The latest data on oil consumption suggest the dip in consumption that appeared in 2008 after the global financial crisis quickly reversed. The contraction in oil has now turned to expansion with consumption up 4% y/y globally.

According to the latest reported information from the Energy Information Administration (EIA), EIA oil consumption is up 4% for 2010 from 2009. The data oil consumption data suggests the global economy has recovered from the financial crisis and is translated into higher oil demand.

Figure 1 Global Oil Demand

WE have seen economic contraction result into declines in oil demand before. Oil demand dropped in the 1979 to 1983 period with of a 10% decline per year. On a global basis, oil demand declined approximately 2% in 2009 from 2008, but is not up nearly 4% in 2010

In the US, oil demand dropped 5.7% in 2008 and 3.7% in 2009 with demand in 2010 increasing 3.8%. The oil consumption trend in the US suggests the decline in oil demand was cyclical as apposed to any structural changes in US consumer demand.

Figure 2 US China & India Oil Consumption

The real story is the growing demand for oil from China and India. According to data from The Centre for Global Energy Studies (CGES) , the demand for oil from China is up 100% from in the last ten years. China’s oil consumption rate has grown from 4.8 million barrels per day (MBPD) to 9.6 MBPD amounting to half of the total US consumption. In 2010 the growth in oil demand in China is up 17%.

The demand for oil in India is also increasing. Oil consumption in India is up 58% in the last ten years and up 8% in 2010.

Figure 3 China and India Oil Demand

The bottom line is that is demand for oil continues to increase and we expect further increase in oil prices.

After reviewing oil data from the Energy Information Administration (EIA), Global Petroleum Consumption , it may be helpful to put energy consumption into perspective. Most of us are quite familiar with alternative energy such as solar and wind, but the reality is, even if solar and wind could supply all of electric energy needs, the majority of our energy needs is still predicated on access to oil.

While industry experts and scientist debate whether more drilling will ameliorate the energy challenge we face, let’s look at a couple of data points. Figure 1 US Oil Field Oil Production and Drilling Rigs – illustrates that higher drilling activity as measured by Baker Hughes Rig Count data does not necessarily correlate to more oil production as measured by US Oil Field Production by the EIA. Higher drilling activity does not produce more oil.

Figure 1 US Oil Field Production and Drilling Rigs
Source: Energy Information Administration and Baker Hughes research

Despite the large investment in drilling rigs that more than doubled from 1,475 in 1974 to over 3,100 in 1982, US oil production remained relatively flat. Moreover, even the most recent drilling expansion activity that again more than doubled from 1,032 rigs in 2003 to over 2,300 rigs in 2009, resulted in relatively flat oil production, suggesting that on the margin unit oil production per drilling rig was declining. Perhaps even more disturbing is that the most recent drilling activity in the US was accomplished through extensive use of technology. Seismic imaging technology is being used to better locate oil deposits and horizontal drilling technologies are employed to more efficiently extract the oil, yet oil production still lags historic levels. While on the margin, newly announced offshore drilling could add to domestic oil production, extraction costs of oil will continue to rise adding to further oil price increases.

However, what is most profound is our dependence on oil for most of our energy needs similar to how wood was used for fuel construction material during the 1300’s and 1600’s. If we translate energy consumption into equivalent measuring units such as kilowatt-hours, we can compare and rank energy consumption. Although electricity is captured through consumption of several fuels most notably coal, a comparison of energy usage between oil and electric provides an interesting perspective.

Figure 2 Energy Perspective – provides a simple comparison of the consumption of oil and electricity measured in gigawatt-hours (one million kilowatt hours). A barrel of oil is equivalent to approximately 5.79 million BTUs or 1,699 KWH and the US consumed approximately 19.5 million barrels per day equating to 12 million gigawatt-hours a year. The US uses 4 million gigawatt-hours of electric energy annually. The critical point is that even if solar and wind supplied all of our electric energy needs, it would still only comprise 30% of our total energy needs. Therefore, without an energy strategy that facilitates migration towards a substitute for oil, particularly for transportation, we are missing the boat.

Figure 2 Energy Perspective

It’s not all doom and gloom. Technologies are advancing, economies of scale are driving costs lower, and the economics for new approaches to transportation are improving. From hybrids and electric vehicles benefiting from advances lithium-ion batteries to hydrogen fuel cell vehicles getting 600 miles on a tank of fuel. These advanced technologies could mitigate our addiction to oil, however, without formulating an energy strategy directing investments towards optimizing the economics, energy efficiency, environment, and technology, we may miss the opportunity.

The bottom line is that oil is supply-constrained as there are no readily available substitutes, and therefore, without a means to rapidly expand production; supply disruptions could have a pernicious and painful impact on our economy, national security, and welfare.

Despite the global economic recession, preliminary data suggest oil demand remains rather resilient. According to the latest reported information from the Energy Information Administration (EIA), Global Petroleum Consumption is down one percent y/y in 2008 while China and India show increases of 4% and 5%, respectively. However, current data through September 2009, show oil demand fell quite precipitously in the US. Through September 2009, oil consumption is down over two million barrels per day form the 2007 annual average (an 11% decline). Most of the change in oil consumption is cyclical and with an economic recovery expected, oil demand should rebound and perhaps drive prices higher.

Figure 1 US Average Annual Oil Consumption

Historically, the US has seen this type of demand erosion before. From 1979 to 1983, oil demand in the US declined 28% with annualized rate of a 10% decline per year. Over this same period, oil prices actual rose despite the fall in demand. Oil prices by barrel (42 US gallons) rose from $3.60 in 1972 to $25.10 in 1979. Oil prices are up significantly in 2009. In January 2009, oil was traded at $33.07 a barrel and in January 2010, oil is trading at 2010 Oil prices $78.00 per barrel.

On a global basis, oil demand has only contracted by one percent in 2008, the latest data from the IEA. Despite the fall out in US oil demand, global markets driven from demand from China and India, has kept the global demand for oil relatively stable.

Figure 2 Global Oil Demand

The growing demand for oil from China and India increased their respective share of the global oil markets from 3% and 1%, respectively in 1980 to over 9% and 3% in 2008. At the same time, the US share of global oil consumption has declined from 27% in 1980 to under 23% in 2008. See Figure 3 China and India Oil Demand.

Figure 3 China and India Oil Demand

The bottom line is that as financial growth emerges across the globe, oil demand should increase commensurately and with oil process already at elevated levels, further prices increases are expected. – demand for oil will increase and so will oil prices.

The development of an energy efficiency strategy incorporates analysis of energy expenditures and energy consumption. The energy strategy must incorporate dynamics between costs, budgets and the consumption of energy including the monitoring of kilowatt-hours (KWH) of electricity and liquid hydrocarbon fuels consumed. By analyzing both the financial and the energy consumption components we are better positioned to frame the scope of the energy efficiency projects.

We start with a comprehensive energy audit analyzing energy consumption and expenditures. After determining which activities offer the fastest, cheapest, and greatest economic impact we are then able to define the scope of energy efficiency projects. The next step in the energy strategy process is to assess, rank and specify energy saving opportunities. At this phase, we have a broad understanding of the scope of energy efficiency projects within the appropriate budgetary considerations.

Conduct Energy Audit and Analyze Energy Spending

Upon analysis of the energy expenditures and the appropriate budgetary considerations, we commence with an energy audit to examine the dimensions of energy consumption. The energy audit establishes an energy efficiency baseline for buildings and vehicles. In the energy audit, energy consumption is measured by source and activity using monitors attached to branch circuits, gas pipes, and fuel lines. In this manner, energy consumption is evaluated from a financial and physical perspective and baseline usage patterns are established for electricity and other fuels.

During the energy audit, an analysis of energy intensity is measured. For buildings, energy consumption is measured in kilowatt-hours per square-foot to identify which activities consume the most energy. The energy intensity measurements are then ranked by consumption activity and compared to actual energy expenditures.

The purpose of the energy audit is to establish a baseline of energy consumption and the energy intensity associated with each building, department, vehicles, and/or activity usage category. By constructing an effective energy efficiency strategy that identifies and measures energy demand by activity, a better understanding of economic- and financial-impact is established. The critical component to the energy audit is measurement and verification were wireless Internet-based energy monitoring provide data before and after energy efficiency projects commence. The energy audit and energy monitoring systems together with financial analysis of energy consumption serve as the framework to rank and assess energy efficiency projects.

Heuristically, energy consumption in buildings is tied to lighting; and heating, cooling, and ventilation systems see Energy Intensity . The following chart, Figure 1 serves to illustrate which activities contribute most to energy consumption in buildings.

Figure 1 Kilowatt-hours (KWH) per Square Foot

According to information provided by the DOE, lighting, cooling and ventilation alone account for nearly two-thirds of all energy consumption in a building. For perspective, electric energy demand is increasing at an annualized rate of 1.6%. According to the Energy Information Administration (EIA), demand for electricity grew 21% between 1995 and 2006.

The energy consumption audit provides a means to assess which activities should be further analyzed for energy efficiency projects. The baseline energy usage measured in KWH per square foot serves as the framework to evaluate that locations and activities could benefit from lighting retrofits, equipment upgrades, structural improvements, and energy monitoring systems.

As a consequence of increasing energy consumption in buildings, electric generation relies extensively on hydrocarbon fuels that carry adverse environmental effects. Figure 2 illustrates the proportion of coal and other hydrocarbon fuels that are used to generate electricity in comparison to renewable energy sources. Coal still accounts for nearly half of all electric generation while contributing the most in terms of harmful emissions such as carbon dioxide, nitrous oxide, and sulfur dioxide.

FIGURE 2: Electric Generation Method

As part of the energy audit process for buildings, an energy consumption analysis of lighting and HVAC systems is evaluated along with the building’s insulation R-Value (resistance to heat flow where the higher the R-value, the greater the insulating effectiveness). In addition to lighting and HVAC systems, specialized equipment may also account for large energy demand. During our energy audit, we plan to identify and measure energy usage of special equipment in order to construct energy efficiency initiatives with clearly defined and measurable energy reduction targets.

Energy efficiency for transportation vehicles is one of the most significant factors to manage. The fact that there are no real substitutes for oil in the transportation industry illustrates two important points: 1) structural changes to driving patterns are required to see appreciable changes to oil consumption and 2) government authorities are vulnerable, with no readily available substitutes for oil, supply disruption could negatively impact transportation systems. Therefore, we emphasize fuel management systems for fleets and vehicles that monitor fuel consumption and efficiencies. DOE studies have indicated that changing driving habits could improve fuel efficiency by up to 30%.

Vehicle mounted devices that integrated fuel consumption feedback as the vehicle is driven promotes higher fuel efficiency. These off the shelf products are cost-effective, offering payback in months that dramatically improves fuel efficiencies. Aside from routine tune-ups, limiting weight, and checking tire pressure, augmenting driving patterns through gauges that provide feedback on fuel efficiency make the difference in saving energy.

In most situations, fuel management systems can be installed without significant mechanical aptitude. The ScanGaugeII from Linear-Logic is useable on most vehicles manufactured after 1996 including Gas, Diesel, Propane and Hybrid Vehicles and are designed to be installed by the consumer with plug-and-play instructions.

Identify and Measure Energy Demand by Activity

From the Energy Audit, the energy intensity of targeted buildings and fuel efficiencies of official vehicles are established. In buildings, it’s the lighting and heating, ventilation, and cooling that comprise the bulk of energy consumption.

Heating, ventilation, and cooling represent a significant portion of energy consumption in buildings and are a priority target for energy analysis. The Seasonal Energy Efficiency Ratio (SEER) is employed as an assessment of the equipment and analyzed in conjunction with building insulation. The efficiency of air conditioners is often rated in SEER ratio, which is defined by the Air Conditioning, Heating, and Refrigeration Institute and provides a standard unit measure of performance. The higher the SEER rating of a cooling system the more energy efficient the system is. The SEER rating is the amount of BTU (British Thermal Units) of cooling output divided by the total electric energy input in watt-hours.

For heating systems in a building, Annual Fuel Utilization Efficiency (AFUE) is used to measure and compare the performance of different systems. DOE studies have indicated that even with known AFUE efficiency ratings, heat losses defined as idle losses contribute to degradation in heating system efficiency,

To analyze energy consumption of heating and air conditioning systems (HVAC), we evaluate the building’s R-Value in comparison to the energy efficiency of the current heating and air conditioning systems. The energy demand evaluation includes a cost-benefit analysis comparing options in either HVAC system upgrade and/or improvements to the building’s insulation R-Value. By comparing the buildings R-Value in conjunction with HVAC efficiency performance, projects offering the greatest cost effectiveness are identified. The building’s R-Values can be measured using FLIR Systems infrared camera and software system. In this manner, the replacement cost of an HVAC system and costs to improve the building’s R-Value are analyzed to measure economic benefits. This information will allow the building owner to make an informed decision on whether any energy efficiency investment into HVAC upgrade or improvement to R-Value demonstrate economic benefit, i.e. positive financial return.

Consideration for heating and cooling systems upgrades are assessed by equipment SEER and AFUE ratings, installation costs, and efficiency payback. After equipment assessment is complete, proposals will be provided along with estimates for upgrade costs and payback analysis.

Benchmark and Analyze Energy Intensity

After conducting the energy audit, and compiling data on energy usage by activity category, we benchmark and analyze energy projects offering the greatest opportunities. As illustrated in Figure 3, energy efficiency for lighting systems can be substantially improved by retrofitting legacy light fixtures with higher efficiency fixtures and bulbs.

The energy audit and analysis provide the framework to evaluate energy efficiency projects. By analyzing energy consumption and the economic benefits associated with the energy savings projects, the most efficient and economically beneficial initiatives are identified and ranked.

FIGURE 3: Energy Savings in KWH per Square Foot Figure 1 Kilowatt-hours (KWH) per Square Foot

Establish Measurable Goals and Objectives

To establish relevant goals and objectives we are evaluating projects that are adhering to the SMART goal approach: specific, measurable, attainable, realistic and timely. Energy efficiency gains are most pronounced with lighting retrofits and energy monitoring in buildings in buildings and energy monitoring in vehicles.

After conducting an energy audit, analyzing energy consumption activities and the economics of energy efficiency projects, realistic and achievable energy savings goals are defined. Key performance metrics for energy savings are defined for buildings and vehicles. Key performance indicators are established for each project. For example, KWHs saved are defined for lighting retrofit projects, efficiency improvements for HVAC system upgrades, R-Value improvements for building insulation, and MPG gains for vehicles.

For each energy savings project, timelines are established with clearly defined milestones. Energy projects are presented with costs; expected energy savings measured in energy and dollar units, cost benefit analysis, and timelines.

Architect the Deployment of Energy Monitoring Systems

One of the first energy initiatives to consider in any energy savings project is the installation of an energy monitoring system for vehicles and buildings. Energy monitoring systems demonstrate the fastest and most economical pathways to achieving energy savings.

Energy monitoring systems for motor vehicles also demonstrate positive economic returns and real energy savings. The $180 energy-monitoring device with 10% fuel efficiency gain achieves breakeven at 14,500 miles with gasoline costing $2.50 a gallon.

Evaluate Feasibility of Renewable Energy Projects

Renewable energy projects such as solar and wind energy systems are often costly with long payback periods. Without tax incentives and grants, renewable energy projects are unable to demonstrate positive financial returns. However, utility rates for electric are expected to increase, improving the case for renewable energy projects. To improve the viability of alternative energy projects, energy efficiency projects such as lighting retrofit serve to lower energy consumption and therefore enhance the feasibility of solar and wind energy projects.

The fall in oil consumption was most dramatic following the escalating price of crude oil to $145.16 per barrel on July 14, 2008 then at any other point over the last several years. Price elasticity, a key concept in Economics 101, which measures the impact of price change to changes in unit volume sold, is helpful in determining which products have readily available substitutes or which, like oil are inelastic with no real substitutes.

As illustrated by Benjamin Graham and David Dodd in their book Security Analysis, 1940 edition, during the 1930’s the economy had a dramatic impact on spending and consumption particularly on discretionary items such as travel. In one illustration, the change in demand was most pronounced in railroad revenues where tickets purchased for railroad travel, declined 51% from 1929 to 1993 as measured by gross receipts for the railroad industry. Over this same period, spending on the consumer staples (inelastic demand), such as electricity encountered a decline of only 9%.

While almost everyone would agree that the current economic climate is one of the most challenging since the 1930’s, a quick review of oil consumption over the last several years illustrates that demand has not significantly contracted, suggesting driving habits only changed when prices escalated to over $100 per barrel. Oil consumption dropped only 4.9% from January 2008 through January 2009.

Figure 1 Oil Consumption

As seen from Figure 1, the sharp drop in oil consumption in September 2008 of 8.3% appears as an aberration when measured over the whole year. The fact there are no real substitutes for oil in the transportation industry illustrates two important points: 1) structural changes to driving patterns are required to see appreciable changes to oil consumption and 2) how vulnerable we are as a nation with no readily available substitutes for oil in the transportation systems.

Figure 2 Oil Demand in China and India

With China and India undergoing significant structural changes as they rapidly migrate towards motor vehicles for transportation suggests the demand for oil should continue to grow relatively unabated. Until the price of oil climbs back over $100 per barrel, we will not see the structural changes necessary to develop alternatives to oil in the transportation market.

The bottom line: energy and in particular, oil has not experienced a dramatic drop in demand during 2008 suggesting driving patterns were influenced more by the price of oil then the struggling economy. We must begin to shift emphasis to alternative energies such as solar as well as hybrids and electric vehicles.

America’s appetite for oil declined sharply as the economy weakened over 2008. According to the latest reported information from the Energy Information Administration (EIA), Monthly Oil Consumption oil consumption declined 13% y/y from September 2007 through September 2008.

Historically, the US has seen this type of demand erosion before. From 1979 to 1983, oil demand in the US declined 28% with annualized rate of a 10% decline per year. Over this same period, oil prices actual rose despite the fall in demand. Oil prices by barrel (42 US gallons) rose from $3.60 in 1972 to $25.10 in 1979. In 1983, oil prices increased to $29.08 a barrel, representing an increase of nearly 16% from 1979.

Economics would normally dictate that as demand declines so should prices. However, the geopolitical events and oil supply disruption maintained higher oil prices despite the subsequent decline in oil demand. It was not until structural changes in energy conservation and driving patterns were felt before leading to a fall in oil prices during the 1980’s.

Figure 1 Monthly Oil Consumption

As illustrated in Figure 1, the precipitous fall in oil demand over the last half of 2008 is quite dramatic in comparison to historical price data. The large fluctuations in monthly oil consumption during the 70’s and 80’s, were primarily due to supply disruptions. The higher oil prices resulting from supply disruptions over this period led to structural changes in the energy market that later resulted in falling oil prices.

Figure 2 Oil Prices

While falling demand and rising oil prices during the 70’s and 80’s is an anomaly, we see from Figure 2, that currently there is significant correlation between falling oil demand and a subsequent decline in the price of oil. Excluding the peak oil price in July 2008, oil declined 33% from the average price per barrel of $64 in 2007.

Perhaps the precipitous fall in oil prices can explain why demand for oil on a global basis has not declined as dramatically as in the US. As we can see from Figure 3, the drop in US oil consumption is matched with a slight increase in demand in Europe and only a moderate decline in Japan.

Figure 3 Global Oil Demand

The bottom line is the financial shock that hit global markets is dramatically impacting consumption. As a recovery inevitably ensues, demand for oil will increase and so will oil prices. Let’s not be complacent with hydrocarbon fuels. Falling energy prices act as a disincentive for investment into alternative energies.

To understand current energy prices it may serve us to examine historical energy prices. Our theme is energy economics and specifically that energy prices follow the laws of supply and demand to set pricing.

There are some interesting perspectives on historical energy prices from several books including Security Analysis, 1940 edition by Benjamin Graham and David Dodd, The Great Wave, by David Hackett Fischer; and The Industrial Revolution in World History, by Peter Stearns. These books provide extensive data on pricing, industry revenues, and the framework that energy and technology serve in the economics of the industrial world.

Figure 1 Historical Energy Prices

With the risk of oversimplification, our first figure shows there have been four distinct energy prices waves that have rippled through history. The scarcity of wood that was used for building homes, heating, and tools became increasing scarce as deforestation spread through Europe in the 1300s and followed again in the 1600’s. Coal prices rose rapidly with the War of 1812 and the Napoleonic Wars. Oil prices peaked in 1982 and to an all time high of $145.16 on July 14, 2008.

Figure 2 Medieval Wood Prices

During the Medieval period in world history wood prices increased nearly threefold according to David Fischer in the The Great Wave. Wood prices rose with scarcity and peaked in 1320 as impact of the Bubonic Plague began to kill a quarter of Europe’s’ population. Twenty years from its peak in 1320, wood prices declined by 48% as the Bubonic Plague reduces the population and in turn, lowering the demand for wood.

Figure 3 Wood Prices

Figure 3. Illustrates the rapid rise in the demand for wood as the growing world populations benefited advances in science and agriculture from the Renaissance period. Wood is used for just about everything and prices climb as more land is used for agriculture leading to deforestation exacerbating the wood shortage. As demand for wood increases, prices subsequently follow. By the end of the 1600’s, coal begins to substitute for wood as an energy alternative.

With advances in technology came improvements in coal mining and transportation that allowed coal to substitute for wood as an energy source. With the invention such as Thomas Newcomen’s steam, powered pump in 1712 that facilitated coal mining and James Watt’s steam engine in 1765 that lead to advances in transportation including railroads and machinery, coal grew in importance as an energy source. These advances in technology enabled greater supplies of coal to enter the market which lead to declines in energy prices.

Figure 4 Coal Prices

We can gleam from Figure 4 that coal prices peaked in 1810-to-1815 coinciding with the War of 1812 and the Napoleonic Wars. The technological advances in mining and transportations fostered the development of an infrastructure to support the coal industry. The price of coal rose as wars ragging in Europe and the US, increased the demand for materials and supplies such as coal. However, as the wars came to an end, the abundant supplies of coal allowed prices to fall keeping energy prices low.

Oil entered the picture with the drilling of the first oil well in northwestern Pennsylvania in 1859 and the Internal Combustion Engine in 1860 that facilitated the development of the oil industry.

As oil emerged to become the dominant fuel of the 20th Century, it’s only recently that we face supply shortages. To better understand the dynamics of energy pricing in the face of changing demand, a review of spending on railroads and electricity may serve as a surrogate for discretionary and consumer stable spending patterns.

Figure 5 Industry Segment Revenues

Figure 5 illustrates changes in the aggregate revenues of railroads in comparison to electric utilizes during the Great Depression. Copious notes taken by Graham and Dodd for their book Security Analysis help to demonstrate the economic laws of supply and demand.

The change in demand was most pronounced in railroad revenues. Expenditures on railroads, the more discretionary of the two industries, declined 51% from 1929 to 1993 as measured by gross receipts for the railroad industry. Over this same period, spending on the consumer stable, electricity only encountered a decline of 9%. In economic terms, railroads demonstrate greater demand elasticity meaning there is greater change in demand at prices change or this period, disposable income. While there is some discretionary portion of our spending associated with oil, a large portion of spending on oil is out of necessity. Therefore, even during times of great economic distress, the propensity for energy consumption is not eradicated entirely.

The bottom line: Energy pricing will continue to be dictated by supply and demand. Hydrocarbon fuels such as oil are finite in nature and therefore, without definitive strategies to cultivate alternative energy resources we will remain hostage to the vagaries in energy prices..

Access to energy was instrumental fueling the Industrial Revolution. Over the last 200 years, industrial nations have migrated from wood to coal and now to oil as a source of energy. During the 1700’s, wood was used for just about everything from fuel to constructing houses and building wagons and even tools. As demand for wood increased, the cost of wood rose as deforestation led to the scarcity. The scarcity of wood resulted in deteriorating economics.

It was the availability and access to coal that enabled the growth of Industrial Revolution by providing accessible energy. The Industrial Revolution was predicated upon the availability of Labor, Technology, Capital, and Energy. Scarcity of any of these inputs could undermine economic growth, as was the case with capital during the Great Depression of the 1930’s and the Energy Shock of the 1970’s.

Oil, driven by rapid growth in automobile usage in the U.S, has replaced coal as the main energy fuel. According to the Energy Information Administration (EIA), the 70% of oil consumption in the U.S. is for transportation .

Figure 1 US Oil Imports

Figure 1 illustrates US historical oil imports, as measured by the Energy Information Administration in U.S. Crude Oil Field Production (Thousand Barrels per Day) that dates back to 1970. The EIA provides oil import data dating back to 1910. To estimate the amount of money the US spends on oil imports every year, we can use the data from the State of Alaska Department of Revenue, which provides historical data on the price of oil an derive an average yearly figure.

Figure 2 US Oil Import Spending

Figure 2. appears quite staggering given the amount of money we send to oil producing countries. The US is spending hundreds of billions to import oil. According to the EIA, the US imported an average of 10,031,000 barrels per day equating to $263 billion in imported oil during 2007 when the State of Alaska measured the yearly average spot price for a barrel of oil at $72.

According to Solarbuzz, Germany leads the world in solar photovoltaic (PV) installations with 47% of the market while China increased its market share of PV production from 20% to 35%. The US accounts for 8% of the world solar PV installations. Solarbuzz indicates the global solar PV industry was $17 billion in 2007 and the average cost of solar electricity is $0.2141 per KWH. If a portion of our $260 billion sent to oil producing countries were to be invested into solar energy, perhaps the US would not lag the world in alternative energy.

The bottom line is that the money spent on importing oil has a deleterious impact on our economy and continues our dependence on hydrocarbon fuels producing carbon and other harmful byproducts that negatively impact our climate and health of our children. The longer we are dependent on oil, the longer our economy and environment suffer. Use your vote for alternative energy and not drill baby drill.

Rising energy prices and our diminishing supply of oil threaten our national security. Without access to energy our economy and national defense are vulnerable to collapse. As a solution to our energy needs, we hear political rhetoric to expand oil drilling, but our energy strategy requires a long term solution that means embracing alternative/renewable energy technologies such as solar and wind. It only takes a quick review of oil production statistics to realize how formidable the challenge is that we face.

According to the Energy Information Administration (EIA) in 2007, the US consumed 20.6 million barrels of oil per day (bpd) but we were only able to produce 8.5 million bpd, leaving a deficit of approximately 12.2 million bpd. This means the US needs to import 60% of its oil and at a cost of $130 per barrel, the US will spend approximately $600 billion a year on imported oil.

Oil prices have increased dramatically with an increase of 420% since 2001. The combined impact of rising prices and diminishing oil production leaves the US in a precarious position. Yet, drilling for more oil may not rectify this tenuous situation.

As an example, back in the 1980’s, drilling activity in Alaska helped to ameliorate the oil crisis of the 1970’s. Today, oil production in Alaska has declined significantly. From its peak in 1988, oil production in Alaska has decline 64%. In Figure 1, oil production in Alaska in contrasted to the price of oil per barrel from 1980 to June 2008.

Figure 1 Alaska Oil Production

When we measure the supply and demand for oil, we find in the US, it is really a supply problem. According to the EIA , US demand for oil is growing at an annual rate of one percent over the last ten years, but oil production is down 20% since 1987.

Figure 2 US Oil Production

The energy problem however, is global. The demand for oil in the US may slow, yet supply constraints driven by growing consumption in developing countries could exacerbate this already bleak picture. On a per capita basis, the US consumes approximately 25 barrels of oil per person annually or a little over 600 gallons a year. That figure greatly exceeds other countries and particularly those in developing nations such as China.

In China, oil consumption per person is only 2 barrels or 84 gallons a year. However, oil consumption in China on a per capita basis has increased 88% from 1996 to 2006 according to data from the EIA. Despite China’s one percent population growth, at its current oil consumption growth rate, China is expected to double its current oil consumption by 2015 to over 14 million bpd and exceed the US in oil consumption by 2020. China’s current oil appetite suggests that in 14 years China will require an additional 14.6 million barrels per day. Even if oil producing countries are able to produce the additional oil, those countries that are unable to meet their own needs such as the US and China, will continue to be held hostage to oil producing states.

Figure 3 China Oil Consumption per Capita

The bottom line: the energy model based on hydrocarbon fuels is broken. Neither drilling for more oil will not satisfy our energy needs nor will corn-based ethanol. We need to rapidly embrace electric vehicles using solar, wind, and fuel cell technologies to provide alternative energy solutions. It time to put energy as the most critical component of our national security. Energy should be front and center for the US election. It’s time to invest into clean and renewable energy solutions.

Oil continues to trade above $100 per barrel with the NYMEX CRUDE FUTURE closing at $101.84 on the last day of February 2008 and the US House of Representative passes legislation to raise $18 billion in new taxes for Big Oil to foster development of alternative energies. While President Bush plans to veto the legislation and Republicans claim the legislation unfairly impacts the oil industry, let’s look at the numbers. The legislation calls $18 billion tax over the next ten years so the impact amounts to $1.8 per year. The oil demand is approximately 20.6 million barrels per day according the to latest data from the Energy Information Administration. With oil at $100 per barrel the US will spend about $2 billion a day on oil and that equates to over $750 billion a year. In comparison to the total amount of oil we use, the tax is about 2/10th of one percent.

Figure 1 US Oil Supply and Demand

Well maybe that’s not a fare comparison. The bill, H.R. 6, the CLEAN Energy Act. would roll back two tax breaks for the five largest U.S. oil companies and offer tax credits for energy efficient homes and gas-electric hybrid vehicles.
According to the CNN article, the money to be collected over the 10-year period would provide tax breaks for solar, wind and other alternative energies and for energy conservation. The legislation was approved 236-182, and is expected to cost the five largest oil companies an average of $1.8 billion a year over that period, according to an analysis by the House Ways and Means Committee. So in other words this bill just repeals tax breaks given to Big Oil to become more competitive in the global market.

Figure 2 Oil Prices and World Rig Count

So what is the $1.8 in tax impact on Big Oil? Let’s just look at the impact this would have if just Exxon Mobil Corp (XOM) had to endure the tax only. Exxon Mobil generated $404 billion revenues in 2007, which means if Exxon had to face this tax only, it would be less than ½ of 1% of revenues. Considering that some states impose a 6% sales tax on consumers, a tax impact of 0.2% on the largest oil companies seems rather innocuous.

If the world has to depend upon OPEC oil production, questions do arise over the expansion of oil production and OPEC’s willingness to supply oil despite oil over $100 per barrel. As figure 3 illustrates production among OPEC nations is faltering. Could this be a prelude to Peak Oil?

Figure 3 OPEC Oil Production

The bottom line is that without incentives and further research on alternative energies, the world continues to be held hostage to oil and hydrocarbon fuels which are directly linked to rising CO2 levels and climate change.

From the Industrial Revolution we learned that economic growth is inextricably linked to energy and as a result, our future is dependent upon equitable access to energy. When the Stourbridge Lion made entry as the first American steam locomotive in 1829 it was used to transport Anthracite coal mined in nearby Carbondale, PA to a canal in Honesdale that in turn linked to the Hudson River and onto New York City. Coal fueled the growth of New York and America’s Industrial Revolution because coal was cheap and more efficient than wood.

Advances in science and technology gave way to improvements in manufacturing, mining, and transportation. Energy became the catalyst to industrial growth. Steam power such as Thomas Newcomen’s steam powered pump in 1712 developed for coal mining and James Watt’s steam engine in 1765 were initially used to bring energy to market.

In terms of heating efficiency, coal at the time offered almost double the energy, pound for pound, in comparison to wood. Energy Units and Conversions KEEP Oil offers higher energy efficiencies over coal and wood, but as with most hydrocarbon fuels, carbon and other emissions are costly to our economy and environment.

With rapid growth in automobile production in the U.S., oil became the predominant form of fuel. According to the Energy Information Administration, in 2004 the U.S. spent over $468 billion on oil.

Figure 1 U.S. Energy Consumption by Fuel

We all need to become more conversant in understanding energy costs and efficiency and as a corollary, better understand the benefits of renewable energy such as solar, wind, and hydrogen fuel cells. A common metric we should understand is the kilowatt-hour (KWH) – the amount of electricity consumed per hour. The KWH is how we are billed by our local electric utility and can be used to compare costs and efficiency of hydrocarbon fuels and alternative energies.

One-kilowatt hour equals 3,413 British Thermal Units (BTUs). One ton of Bituminous Coal produces, on the average, 21.1 million BTUs, which equals 6,182 KWH of electric at a cost of about $48 per short ton (2,000 pounds). That means coal cost approximately $0.01 per KWH. To put that into perspective, a barrel of oil at $90/barrel distilled into $3.00 gallon gasoline is equivalent to 125,000 BTUs or 36.6 KWH of energy. Gasoline at $3.00/gallon equates to $0.08 per KWH. So gasoline at $3.00 per gallon is eight times more expensive than coal.

Is oil and gasoline significantly more efficient than coal? Let’s compare on a pound for pound basis. A pound of coal equates to about 10,500 BTUs or approximately 3.1 KWH per pound. A gallon of gasoline producing 125,000 BTUs weighs about 6 pounds equating to 6.1 KWH per pound (125,000 /3,413 /6). While gasoline is almost twice as efficient as coal, coal’s lower cost per KWH is why it is still used today to generate electric.

The Bottom Line: the economics of energy determines its use – coal still accounts for approximately half of our electric generation because it has a lower cost than other fuels. However, there are two factors to consider 1) the cost of carbon is not calculated into the full price of coal or other hydrocarbon fuels and 2) the cost of conventional fuel is calculated on a marginal basis while alternative fuel costs are calculated on a fixed cost basis. Meaning the cost of roads, trucks, and mining equipment is not factored into the price of each piece of coal, only the marginal cost of producing each ton of coal. For solar, hydrogen fuel cells, and wind energy systems, the cost to construct the system is factored into the total cost while the marginal cost of producing electric is virtually free. We need a framework to better measure the economics of alternative energy. The impact of carbon on our climate and global warming are clearly not measured in the costs of hydrocarbon fuels nor is the cost of protecting our access to oil such the cost the Iraq War.

Despite the carbon issues surrounding coal, (coal has higher carbon-to-hydrogen ratio in comparison to oil or gas) coal is more abundant and therefore is cheaper than oil. As electric utilities in 24 states embrace alternative energies through such programs as Renewable Portfolio Standards (RPS), perhaps the benefits of alternative energies will begin to combat the negative economics of hydrocarbon fuels.

Ethanol may emit less CO2 and help reduce the demand for foreign oil in the short term, but ethanol and in particular, corn-based ethanol raises food prices, is less efficient than gasoline, diesel, and biodiesel, and is not a substitute for oil.

According to research compiled by National Geographic Magazine , the energy balance of corn ethanol, (the amount hydrocarbon fuel required to produce a unit of ethanol) is 1-to-1.3 whereas for sugar cane ethanol the ratio is 1-to-8. This suggests corn-based ethanol requires significantly more energy to produce than sugar cane ethanol. Corn ethanol is only marginally positive.

A major issue with corn ethanol is its impact on corn prices and subsequently, food prices in general. It is the price of oil that is impacting the price of corn because nearly all ethanol produced in the U.S. is derived from corn. Therefore, corn prices are inextricably linked to oil prices as well as to the supply and demand of corn as food and feedstock. Corn Prices while volatile and impacted from weather and other variables appear to follow the rising price of oil as illustrated in Figure 1. In turn, corn prices are also influencing other commodity prices where corn is used for feed for livestock.

The rising motor vehicle usage in China and India is escalating the already tenuous situation in the oil markets. With ethanol tied to oil prices we are beginning to see corn prices exacerbate the inflationary pressures at the retail level. Over the last year consumers are paying more for food with large increases in the prices of eggs, cereal poultry, pork, and beef which are tied to corn.

Figure 1 Corn Prices

Senate legislation for Renewable Fuels Standard calls for ethanol production to increase to 36 billion gallons by 2022 with 21 billion derived from as cellulosic material such as plant fiber and switchgrass . Corn is expected to comprise 42% of the ethanol production in 2002 from virtually all today. The fact is that ethanol production at its current level of 6 billion gallons equates to only 4% of our gasoline usage and is already impacting food prices. Gasoline consumption in 2005 amounted to 3.3 billion barrels or 140 billion gallons. Current estimates put gasoline consumption at 144 billion gallons a year in 2007. Even if vehicles could run entirely on ethanol, there is not enough corn harvest to substitute our demand for oil. We need a cohesive and coordinated effort using multiple technologies to develop alternative energies to reduce our dependence on foreign oil.

Performance

According to Renewable Fuels Association ETHANOL FACTS:
ENGINE PERFORMANCE, ethanol offers higher engine performance with octane rating of 113 in comparison to 87 for gasoline and has a long history in the racing circuit. In 2007, the Indy Racing League, sponsors of the Indianapolis 500 started using ethanol in racecars. However, the higher engine performance may come at a cost of lower fuel efficiency.

Table 1 Specific Energy, Energy Density & CO2

Efficiency

Gasoline offers 56% higher energy efficiency (specific energy) over ethanol as measured by kilo-joules per gram (kj/g). (As a reference: 1 kilowatt-hour = 3,600 kilojoules = 3,412 British Thermal Units) Biodiesel with 35 kj/g is 33% more energy efficient than ethanol at 24.7 kj/g.

In terms of energy density, ethanol would require larger storage capacity to meet the same energy output of gasoline diesel, and biodiesel. Ethanol requires a storage tank 48% larger than gasoline and 41% larger than diesel for the same energy output.
Please see Hydrogen Properties and Energy Units

For a quick review of Specific Energy and Energy Density – (Molecular Weight Calculator) the specific energy of a fuel relates the inherent energy of the fuel relative to its weight and is measured in kilo-joules per gram.

CO2 Emission

The molecular weight of CO2 is approximately 44 with two oxygen molecules with an approximately weight of 32 and one carbon atom with a weight of 12. During the combustion process, oxygen is taken from the atmosphere producing more CO2 then the actual weight of the fuel. In the combustion process a gallon of gasoline weighing a little over six pounds produces 22 pounds of CO2.

CO2 emission is a function of the carbon concentration in the fuel and the combustion process. During combustion ethanol produces approximately 13 pounds of CO2 per gallon. Gasoline and diesel produce approximately 22 and 20 pounds per gallon, respectively. CO2 emissions per gallon appear quite favorable for ethanol. However, the results are less dramatic when CO2 emissions are compared per unit of energy produced.

Figure 2 CO2 per KWH

When measured in pounds of CO2 per kilowatt-hours (KWH) of energy, the results show ethanol producing 6% less CO2 than diesel or biodiesel and 5% less than gasoline. In the case of ethanol, the lower specific energy of the fuel negates the benefit of its lower CO2 emissions. Meaning more ethanol is consumed to travel the same distance as gasoline or diesel thereby limiting the benefit of its lower CO2 emissions.

The bottom line is ethanol does not ameliorate our dependence on foreign oil and while it demonstrates higher performance for racecars, it is still less efficient than gasoline diesel, and biodiesel, and diverts food production away from providing for people and livestock. The reality is there are special interest groups that obfuscate the facts about ethanol for their own benefit. The real solution to our imminent energy crisis is alternative energies including cellulosic ethanol, solar, hydrogen fuel cells, and wind.

A brief review of history and in particular the industrial Revolution, it’s quite apparent that economic growth is inextricably linked to energy. As energy is tied to our economy, our future is dependent upon equitable access to energy. This in turn sets the framework of our dependence on oil and hence, why our national security is tied to securing the flow of oil.

Eighteenth-Century England gave birth to the Industrial Revolution. Four critical components provided the framework enabling the Industrial Revolution: Labor, Technology, Risk Capital, and Energy

Improving efficiencies in agriculture lead to an increase in the food supply while minimizing the amount of labor required to cultivating crops. The improving agriculture efficiencies lead to population growth and an available labor force that began to migrate to the cities.

Advances in science and technology gave way to improvements in manufacturing, mining, and transportation. It was the harnessing of steam power such as Thomas Newcomen’s steam, powered pump in 1712 for coal mining and James Watt’s steam engine in 1765 that lead to railroads and machinery.

Risk capital was also an important element for the development of the Industrial Revolution. Risk capital and the entrepreneurial spirit that allowed capital to be applied innovation helped transition England into the largest economy in the world.

And Energy. Access to an available source of energy was instrumental fueling the Industrial Revolution. With wood being used for just about everything in the early 1700’s from housing, wagons, tools, and fuel, deforestation lead to energy scarcity. It was coal that enabled the growth of Industrial Revolution by providing an accessible energy source.

With rapid growth in automobile production in the U.S., oil became the predominant form of fuel. According to the Energy Information Administration, in 2004 the U.S. spent over $468 billion on oil. Given that we import nearly 60% of the oil we consume, most of our wealth travels abroad. More emphasis on alternative energies could help ameliorate our dependence on oil.

Figure 1 U.S. Energy Consumption by Fuel

While solar and wind energy have seen some very strong growth, alternative energy still account for less then 2% of our global energy production.

We need to realize that our dependence on oil could cripple our economy. Supply constraints or disruption to oil flow could derail economic activity. It should be an imperative for our national security to develop alternative energies.

With oil prices over $80 per barrel, the National Energy Assistance Directors’ Association in its press release today Record Home Heating Prices for Heating is expecting the average home heating cost for the ’08-’08 season to rise 9.9%. For homeowners using oil heat, heating costs are expected to increase 28% and for homes using propane, a 30% increase is expected.

With rising energy costs driven by costly oil extraction, the potential impact from carbon emissions with our continuing use of oil on climate change and rising sea levels, as well as the potential for fuel supply disruptions, could exacerbate our tenuous relationship with energy.

Eventually, as price rise dramatically, alternative energy becomes more compelling. The problem is our economy is so inextricably link to oil, that our energy security is based on securing foreign oil.

Figure 1 Oil Prices and Home Heating Costs

Without support and research on alternative energies such as solar and fuel cell technologies, we are hostage to oil. The U.S. economy is facing one of the most crises since the Oil Embargo of the 1973. Inflation driven by escalating oil prices is impacting the cost of home heating, transportation, production, materials, and food, particularly as corn is diverted to ethanol production. The housing market is in turmoil with falling home values, rising foreclosures, and a credit crisis that is making it more difficult to secure a mortgage may lead to slower consumer spending. With rising inflation and slower growth we may find ourselves in an economic world described as stagflation that was coined in the ’70’s to describe the bleak environment when gas stations rationed fuel, unemployment grew and the Federal Reserve raised rates dramatically to quell inflation.If we could limit our dependence on foreign oil through investment into solar energy and fuel cell technologies, we would not be impacted by the exogenous events in oil producing nations.

We believe there are a number of catalyst that could serve to dramatically lower the cost of alternative energies. It takes initiatives from all of us to change the balance. After all, oil is becoming more costly to extract, new oil discoveries are in difficult and challenging environments, and oil will eventually run out – it is finite. If we wait to long, our ability to make a difference may not be available.

The U.S. Department of Energy (DOE)’s $23.6 Billion Spending Plan for FY’07 calls for $1.5 billion for the Office of Energy Efficiency and Renewable Energy where spending includes $28 million in solar, $16 million for thin-film photovoltaic manufacturing equipment to reduce the cost of solar panels, $23 million for researching ethanol, and $100 million for carbon sequestration research. However, more than half of the DOE spending is targeted towards research on weapons, defense, and security. Perhaps our national security would be better served if the U.S. were not dependent on foreign oil. Investment into alternative energies like solar and fuel cells could provide us with energy independence with less concern over protecting oil in foreign lands.

Solar energy is significantly more expensive than conventional hydrocarbon fuels. In Green Econometrics’ prior analysis of fuel efficiencies and costs, we found solar energy cost approximately $0.38-to-$0.53 per Kilowatt-Hour (KWH). See Understanding the Cost of Solar Energy
There is considerable variance in the cost of solar energy because sunlight availability varies by geography and climate. With limited sunlight solar costs could be over $1.00 per KWH. In terms of cost per KWH, solar energy is four-to-ten times the cost of hydrocarbon fuels.

Figure 1 Cost per Kilowatt-Hour

For solar energy to be at parity with conventional fuels solar energy needs to be subsidized through tax incentives, utility rebates, and research funding. Research is perhaps the most important aspect of improving the economics of solar energy because through research companies could dramatically lower production costs. The disconnect in solar energy research is limited funding. Funding is required to incubate ideas and new approaches to solar energy in order to develop a roadmap for commercialized products that in turn, could be embraced by venture capital.

The DOE’s research funding for solar is just a drop in the bucket or barrel that better correlates the magnitude disparity. Electric utilities companies are providing electric power generated mainly through coal, which contributes heavily to CO2 emissions, and yet they don’t spend on research and development towards alternative energies. Large energy companies like Exxon Mobil (XOM) don’t have R&D budgets like pharmaceutical or technology companies that spend 14%-to-20% of their revenues on R&D. Merck (MRK) and Genentech (DNA) spent 17% and 20%, respectively on R&D while Microsoft (MSFT) and Google (GOOG) spent 15% and 14%, respectively on R&D in 2006.

If Exxon Mobil were spending 10% of its 2006 revenues of $377.6 billion towards R&D to develop alternative energies, it would amount to over $37 billion, a figure that is larger than the DOE budget of $23.6 billion. DOE spending on solar energy research is approximately $28 million. According to the DOE, U.S. energy expenditures in 2004 were over $869 billion. So with that amount of money being spent on energy, how much should be spent to avoid dependence on foreign oil?

Figure 2 Historic Energy Spending

Solar energy and fuel cell technologies have the potential to ameliorate our energy dilemma of foreign oil dependence and risk of climate change from carbon emissions. While it’s hard to measure the economic impact of climate change, our dependence on foreign oil leaves us with growing $450 billion debt for our presence in Iraq and our national security vulnerable to vagaries of oil prices. The Cost of Iraq War The $450 billion the U.S. is spending in Iraq is almost enough money to equip the 124.5 million homes in the U.S. with a 1 KW solar energy system. The U.S. housing units rose to 126.7 million in 2006. Of course that may not cover your total electric usage that averages about 10,760 KWH per household according to data from the Energy Information Administration Electric Power Annual 2005 – State Data Tables

Can higher R&D spending on solar energy help?
Even some of the leading domestic solar photovoltaic cell suppliers are light on R&D spending. SunPower (SPWR) and First Solar (FSLR) are budgeting their R&D spending towards the single digits as a percentage of revenues. Despite relatively low R&D spending levels, SunPower intends to lower solar panels cost by 50% by 2012. Solar photovoltaic cells undergo the same production processes as semiconductors. Experience curves associated with semiconductor production indicate a 20%-to-30% cost reduction with doubling of production. See The experience curve or cost-volume curve article from the Lockwood group TECHNOLOGY TRANSFER: A PERSPECTIVE The solar energy market is expected to grow at 80% over the next five years according to Rhone Resch, president of the Solar Energy Industries Association Solar Leader Expects >80% Market Growth Even without new advances in photovoltaic materials, with a solar energy market growth of 25% and an experience curve of 30%, solar cost could decline by 30% every three years from about $8.90 a watt ($0.45 a KWH) to $2.14 a watt or $0.11 a KWH in 15 years equal to the current price of electricity. The bottom line is that faster market growth and/or increased funding of solar energy research could significantly improve the economics of solar energy and give the U.S. greater security and energy independence.

Solar and alternative energies represent a very small percentage of our total expenditures on energy. Energy Price and Expenditure Estimates by Source
So a substantial reduction of solar energy costs, assuming somewhat elastic demand, we should see significant growth in solar energy. In addition, if we tax hydrocarbon fuels by their respective carbon emissions, we might begin to see level energy playing field.

Figure 3 Energy Spending

Funding solar energy should be views as a strategic imperative at par with national surety. Energy security should equate to national security and alternative renewable energies should provide us with the means to our energy independence.
