Renewable energy sources including wind, solar, geothermal and hydropower provided over 75 percent of the 1,1229 MW of new electrical generating capacity that went online in first quarter of 2015. The results were published in the recent “Energy Infrastructure Update” report from the Federal Energy Regulatory Commission’s (FERC) Office of Energy Projects. The remaining 302 MW added was from natural gas. FERC reported no new capacity from biomass sources for the quarter nor any from coal, oil, or nuclear power.During Q1 2015, eight new “units” of wind came online with a combined capacity of 647 MW — accounting for 52.64 percent of all new generating capacity. Solar provided 30 units (214 MW), geothermal steam provided one unit (45 MW), and hyrdropower provided one unit (21 MW). Five units of natural gas provided the new capacity from that sector.
According to the SUN DAY Campaign, the numbers for the first three months of 2015 are similar to those for the same period in 2014 when renewable energy sources (biomass, geothermal, hydropower, solar, wind) provided 1,422 MW of new capacity and natural gas 159 MW while coal and nuclear provided none and oil just 1 MW. Renewable energy sources accounted for half of all new generating capacity last year.
Renewable energy sources now account for 16.92 percent of total installed operating generating capacity in the U.S.: water – 8.53 percent, wind – 5.65 percent, biomass – 1.38 percent, solar – 1.03 percent, and geothermal steam – 0.33 percent. Renewable energy capacity is now greater than that of nuclear (9.11%) and oil (3.92%) combined. Moreover, as noted, total installed operating generating capacity from solar has now reached and surpassed the one-percent threshold.
“The trend lines for the past several years have been consistent and unmistakable,” said Ken Bossong, executive director of the SUN DAY Campaign. “Each month, renewable energy sources – particularly wind and solar – increase their share of the nation’s generating capacity while those of coal, oil, and nuclear decline.”
