The idea … Read More

Are we underestimating the growth of solar power?

Electricity from solar power is only a small fraction of electricity generated in the United States and across the globe.  In 2011 the total installed capacity of solar power was around 55 terawatt-hours, and the United States alone needed more than 100 times that much electricity in 2011.
