Solar power is expanding rapidly. The United States now has 77.7 gigawatts (GW) of solar photovoltaic (PV) capacity installed – more than enough to power one in every 10 homes in America.

In the U.S., transportation is climate enemy number one. America’s transportation system produces more greenhouse gas emissions than any other sector of our economy and, on its own, is responsible for 4 percent of the world’s greenhouse gas emissions – more than the entire economies of France and the United Kingdom combined.
