RENO, Nev. (AP) — Opposition from friends, not foes, is creating potential roadblocks to President Joe Biden’s green energy agenda on federal lands in the blue-leaning, Western swing state of Nevada. Two lithium mines and a geothermal power plant in the works in the biggest U.S. gold-mining state are under attack from conservationists, tribes and others who otherwise generally support Biden's efforts to expedite the transition from fossil fuels to renewables. The conflicts put a spotlight on an emerging reality as the Biden administration tries to meet its goal of having the U.S. power grid run on clean energy by 2035.
