The U.S. Department of Energy has recently published it “2017 U.S. Energy and Employment Report”. In the report, it highlights the employment numbers for the energy sector in the United States.
For the period of Q2 2015 to Q1 2016, employment in the geothermal sector in the U.S. (BUT looking only at the electricity sector), went down from 7,645 in Q2 2015 to 5,768 in Q1 2016. This actually shows that not much has happened in geothermal development in the U.S. around that time. .. and it is actually the only renewable energy and overall energy technology that has not been able to see an increase in employment.
