U.S. Electricity Generating Capacity Additions 2010-2017
Solar continues to drive a growing portion of new electric generating capacity additions. Last year in 2016, solar ranked as the No. 1 source of new capacity additions. Building off that momentum, solar accounted for 30% of all new electric generating capacity installed in the U.S. in Q1 2017, ranking as the second-largest driver of capacity additions across all fuel types.
When we look at the 1st graph, we can see that 2014 was the last year in which coal was newly installed. Over the last 3 years there were no new coal additions! The 2nd graph shows that in 2015 coal and natural gas were equal in electricity generation, while renewables are 13% of total generation.
