Ethanol offers short-term solutions, but corn-based ethanol is not the answer

January 6th, 2008 · Comments Off on Ethanol offers short-term solutions, but corn-based ethanol is not the answer

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 · 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 […]
