Last year, the U.S. produced a record amount of solar power, generating 39 times more solar power than a decade ago. In 2008, solar produced 0.05 percent of electricity in the U.S. But by the end of 2017, solar generation reached more than 2 percent of the electricity mix — enough to power 7 million average American homes.
Wind has also seen dramatic growth over the last decade. From 2008 through 2017, American wind energy generation grew nearly five-fold. Last year, wind turbines produced 6.9 percent of America’s electricity — enough to power nearly 24 million homes. And the forecast shows even more growth as America’s offshore wind industry begins to takeoff.
Meanwhile, the average American uses nearly 8 percent less energy today than a decade ago, thanks in large part to energy efficiency improvements.
The U.S. transportation fleet is also transforming. Last year, sales of all-electric vehicles broke past 100,000 annual sales for the first time, with 104,000 units sold. As recently as 2010 the number of EVs on American roads numbered in the hundreds, even including plug-in hybrid vehicles. Now there are more than 20 pure-electric models on the market, ranging from affordable commuter cars to ultra-fast luxury vehicles.
