Realizing the Promise of Energy Efficiency

read
Small gains in energy efficiency can create huge savings. So why isn't everyone doing it?

President gets hot and bothered over improving energy efficiency in your home.

On a visit to Home Depot in Alexandria, VA yesterday, President Obama said retrofitting homes to improve energy efficiency is "sexy". What's sexy about it, he said, is "saving money". Ohhkayyy.
