Preliminary numbers for new power-generating capacity built in the US in 2016
Solar: 9.5 gigawatts
Natural Gas: 8.0 gigawatts
Wind: 6.8 gigawatts
Coal: 0 gigawatts
The figure for new solar power is three times the amount built in 2015, which was twice the amount built in 2014. Of course even at that rate of growth, solar power only accounts for just over one percent of total power production in the US. But that is changing fast.
