U.S. Energy Efficiency

What 5 million data points say about energy efficiency potential

Energy efficiency is the country's cheapest power source and the secret to unlocking its potential isn't a new fracking fluid or a new nuclear reactor design. The key is data. A new era of data transparency and quantification is turning energy efficiency from a guesstimate into a reliable and deployable resource that our country can count on. This page is a small peek into that brave new world that brings together data on housing structures, heating and cooling, appliances, and energy habits from more than 120,000 U.S. households. The data illuminates clear opportunities for saving energy and money.

National Highlights
