Formulating an Effective Energy Efficiency Strategy with Measurement and Verification Copyright © 2009 Green Econometrics, LLC
June 27th, 2009 · 1 Comment
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 [...]

Ethanol offers short-term solutions, but corn-based ethanol is not the answer
January 6th, 2008 · 1 Comment
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 [...]

The DOE’s Change a Light, Change the World campaign misses the bigger point.
October 4th, 2007 · 1 Comment
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, - [...]
