According to the latest "Energy Infrastructure Update" report from the Federal Energy Regulatory Commission's Office of Energy Projects, solar, biomass, wind, geothermal, and hydropower "units" provided 394 MW - or 100% - of all new electrical generation placed in-service in November 2013.

There was no new capacity during the month from natural gas, coal, oil, or nuclear power. Renewable energy sources also provided 99% of all new electrical generating capacity in October.

For the first eleven months of 2013, renewable energy sources (i.e., biomass, geothermal, hydropower, solar, wind) have accounted for more than a third (34.9%) of all new electrical generating capacity: 2,631-MW solar, 1,108 MW wind, 519 MW biomass, 121 MW hydropower, and 39 MW geothermal.

That is more than that provided thus far this year by coal (1,543 MW - 12.2%), oil (36 MW - 0.3%), and nuclear power (0 MW - 0.0%) combined. Solar alone comprises 20.8% of new generating capacity (2,631 MW) thus far this year - two-thirds more than its year-to-date total in 2012 (1,584 MW).
