In yet another indication that the clean energy revolution is well underway, a new report finds that solar and wind jobs are growing 12 times as fast as rest of the U.S. economy. These jobs have grown by about 20 percent annually in recent years.

The report from the Environmental Defense Fund (EDF) notes that renewable energy jobs, totaling about 769,000 by the end of 2015, experienced "a compound annual growth rate (CAGR) of nearly 6% since 2012," while "fossil fuel extraction and support services slumped, with a -4.25% CAGR over the same period."

Market forces are driving this phenomenon, due to dramatic reductions in manufacturing and installation costs, coupled with stagnant demand for oil and coal. Unsubsidized solar is now as cheap as coal and natural gas and even wind in emerging markets, and solar prices will continue to rapidly fall.

What's more, these renewable energy jobs cannot be outsourced due to their on-site nature and they pay above average wages.

"Many jobs in the solar and energy efficiency space are in installation, maintenance and construction, making these jobs inherently local and contributing to the growth of local economies. Average wages for energy efficiency jobs are almost $5,000 above the national median, and wages for solar workers are above the national median of $17.04 per hour."

Sustainability jobs – meaning those in energy efficiency and renewable energy, as well as in waste reduction, natural resources conservation and environmental education – now total 4-4.5 million in the U.S., up from 3.4 million in 2011.
