Biofuels Are a Loser, Despite the Hope and Hype

February 21, 2013 by Rod Adams

No amount of genetic engineering can overcome the fundamental limitations of trying to grow fuel for vehicle propulsion and why adding biofuels into our fuel supply makes us less secure.[read more]

Do Lighting Standard Delays Threaten Consumer Choice?

December 21, 2011 by Geoffrey Styles

In just under two weeks, standard 100 Watt incandescent light bulbs will be officially banned in the US, in the first step of a gradual phaseout of Edison's technology. However, as a result of recent Congressional action, enforcement of this regulation has been delayed by about a year, leaving the bulbs and the retailers who sell them in a temporary limbo.[read more]

Appropriations Bill Amendment Attempts To Derail Efficient Lighting

December 21, 2011 by Steve Nadel

It is unfortunate that some members of Congress have inserted a provision in the federal appropriations bill seeking to derail implementation of lighting efficiency standards enacted in 2007 and signed by then-President Bush. Contrary to misinformation being spread by some lamp standard opponents, the standards do not ban incandescent lamps, but merely require incandescent lamps to be more efficient.[read more]
