America Beyond Oil

While ample study has been made of the technical potential to reduce emissions by improving vehicle technology, there have been fewer comprehensive assessments of the potential to cut pollution by reducing traffic levels and improving the efficiency of the transportation system.[read more]

Could Weather Forecasting Be the Secret to Energy Management?

Weather and Energy Efficiency

WeatherBug doesn’t want to just provide its weather data to energy management companies, it wants to be an energy management company. Like EcoFactor, WeatherBug is hardware agnostic and makes micro-adjustments to HVAC to save energy without homeonwers noticing a difference.[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]

We all know that LED lights save energy, help the planet, reduce electrical costs, and last a whole lot longer than incandescent bulbs (the Cree LR6 Downlight LED, for example, is rated to last up to 50,000 hours -- somewhere between 25 and 50 times the lifespan of an incandescent bulb).  But they also have another benefit: they can...[read more]
