Solar and Hydrogen: Energy Economics

October 31st, 2007 · Comments Off on Solar and Hydrogen: Energy Economics

After reviewing some of the details of Honda’s experimental solar-power hydrogen refueling station in Torrance, CA and its fuel cell vehicle several questions concerning efficiency and practicality come to mind. It most be noted that solar and hydrogen don’t emit harmful byproducts such as carbon dioxide or carbon monoxide so both technologies are important to […]

Solar and Hydrogen Energy – where vehicle fuel efficiency is headed

October 17th, 2007 · Comments Off on Solar and Hydrogen Energy – where vehicle fuel efficiency is headed

Despite efforts that have enabled the U.S. to limit its demand for oil, world oil demand is up significantly. Advances in technology such as solar energy and vehicle fuel cell could help the world reduce its dependence on oil. Figure 1 Oil and Gold Prices The U.S. Department of Energy (DOE) and the U.S. Environmental […]

Economics of Solar Energy – price parity and efficiency: Are we there yet?

October 12th, 2007 · Comments Off on Economics of Solar Energy – price parity and efficiency: Are we there yet?

With the Solar Decathlon is taking place in Washington DC today promoting commercially available solar energy technology and oil prices pushing to an all time high of $84/barrel, where are we in terms of cost parity with hydrocarbon fuels. Advances in solar energy technology, lower production costs, and rapidly rising oil costs could bring solar […]

A small investment produces huge savings on your electric bill

October 9th, 2007 · Comments Off on A small investment produces huge savings on your electric bill

My September electric bill arrived the other day and I was interested in comparing my energy savings after swapping 60 and 100-watt light bulbs for Compact Fluorescent Light bulbs (CFL), as recommended by the U.S. Department of Energy (DOE). Our progress in migrating to solar and wind energy is moving slower than expected. The CFL […]

The DOE’s Change a Light, Change the World campaign misses the bigger point.

October 4th, 2007 · Comments Off on The DOE’s Change a Light, Change the World campaign misses the bigger point.

The U.S. Department of Energy (DOE) is quite correct in suggesting that if every household in the U.S. substituted a 100-watt standard light bulb for a Compact Fluorescent Light bulb (CFL), it would eliminate an amount of carbon dioxide (CO2) equivalent to one million automobiles. However, it is the bigger picture that matters, – motor […]

With choices like Biodiesel and Ethanol, what’s the best fuel for your vehicle?

October 3rd, 2007 · Comments Off on With choices like Biodiesel and Ethanol, what’s the best fuel for your vehicle?

With the rapid growth in vehicle use around the world, it would be nice to know what are the most efficiency, economic, and least carbon emitting fuels. The number of motor vehicles on the road is increasing rapidly. The number of cars and trucks in China is up over 3,600 percent in the last thirty […]

What’s Pushing Solar Energy Efficiency?

October 1st, 2007 · 1 Comment

From our post last week we visited some research at California Institute of Technology’s division of Chemical and Chemical Engineering The Lewis Group and its focus on energy conversion and trade-offs between costs and efficiencies for photovoltaic (PV) devices. We are providing a brief and very oversimplified analysis of the physics behind solar energy, and […]
