Wind power surged in 2015 with capacity growing by 12% since 2014, representing 41% of all new capacity installed in the U.S. last year. As of 2015, there were nearly 74,000 megawatts of utility-scale wind power deployed across 41 states and territories -- enough to generate electricity for more than 17 million households.
Utilities and the power sector are installing more utility-scale PV, as the installation cost of utility-scale PV has steadily declined year after year, falling over 64% since 2008. This drop in cost has enabled explosive growth with total capacity reaching more than 13,900 MW in 2015, a growth of 43% over 2014.
Solar PV: Distributed Generation
Over 3,110 MW of distributed systems were installed in 2015, a 34% increase over 2014. This year, the millionth distributed PV system was installed, an indication of how widespread this technology has become.
