The study, published by the Environmental Defense Fund's (EDF) Climate Corps program, says that solar and wind jobs have grown at rates of about 20% annually in recent years, and sustainability now collectively represents four to four and a half million jobs in the U.S., up from 3.4 million in 2011.
The renewable energy sector has seen rapid growth over recent years, driven largely by significant reductions in manufacturing and installation costs. Building developers and owners have been fueled by state and local building efficiency policies and incentives, the report explains.
But, these gains are in contrast to Trump's support for fossil fuel production, his climate change denial and his belief that renewable energy is a "bad investment".
"Trump's current approach is basically ignoring an entire industry that has grown up over the last 10 years or so and is quite robust," Liz Delaney, program director at EDF Climate Corps, told Business Insider.
