Solar power has been growing like crazy. Last year the solar industry installed a record amount of solar capacity. The impact can be seen in the data. According to the Energy Information Administration, in 2012 there were 3.5 million megawatthours of electricity generated by solar photovoltaic panels. In 2013 that more than doubled to 8.3 million Mwh. And to think that a decade ago the U.S. generated just 6,000 Mwh from solar PV.
