"President Trump is nominating a Department of Energy (DOE) official who previously fought against policies meant to promote renewable energy to lead the agency’s renewable energy office.
Dan Simmons has been serving since May 2017 as the acting head of the Office of Energy Efficiency and Renewable Energy. The White House announced late Thursday that Simmons would be nominated to be the office’s assistant secretary, requiring Senate confirmation.
Simmons has been at DOE since Trump took office."
