WASHINGTON, D.C. -- According to the latest "Energy Infrastructure Update" report from the Federal Energy Regulatory Commission's Office of Energy Projects, wind, solar, biomass, and hydropower provided 88.2 percent of new installed U.S. electrical generating capacity for the month of May. Two new "units" of wind provided 203 MW, five units of solar provided 156 MW, 1 unit of biomass provided 5 MW, and 1 unit of hydropower provided 0.2 MW.
By comparison, two new units of natural gas provided just 49 MW while no new capacity was provided by coal, oil, or nuclear power. Thus, for the month, renewables provided more than seven times the amount of new capacity as that from fossil fuels and nuclear power.
For the first five months of 2014, renewable energy sources (i.e., biomass, geothermal, solar, water, wind) accounted for 54.1 percent of the 3,136 MW of new domestic electrical generating installed. This was comprised of solar (907 MW), wind (678 MW), biomass (73 MW), geothermal steam (32 MW), and water (8 MW).
During the same time period, coal and nuclear provided no new capacity, while 1,437 MW of natural gas, 1 MW of oil, and 1 MW of "other" provided the balance.
Since January 1, 2012, renewable energy sources have accounted for nearly half (47.83 percent) of all new installed U.S. electrical generating capacity followed by natural gas (38.34 percent) and coal (13.40 percent) with oil, waste heat, and "other" accounting for the balance.
Renewable energy sources, including hydropower, now account for 16.28 percent of total installed U.S. operating generating capacity: water - 8.57 percent, wind - 5.26 percent, biomass - 1.37 percent, solar - 0.75 percent, and geothermal steam - 0.33 percent. This is more than nuclear (9.24 percent) and oil (4.03 percent) combined. Note that generating capacity is not the same as actual generation. Actual net electrical generation from renewable energy sources in the United States now totals about 13 percent according to the most recent data (i.e., as of March 2014) provided by the U.S. Energy Information Administration.
Some are questioning whether it's possible to satisfy the U.S. EPA's new CO2 reduction goals with renewable energy sources and improved energy efficiency. This latest FERC data and the explosion of new renewable energy generating capacity during the past several years suggest that it can be done.
