No other energy source has seen more rapid growth in the United States over the past half a decade than solar power. But soaring solar installations have begun to distort the power distribution and transmission systems in the top solar-producing states such as California, creating challenges for utilities and the grid.
Battery storage could help alleviate these challenges, and although it is also surging, it is still lagging behind solar capacity additions.
It is no wonder then that despite a continuous decline in U.S. coal power generation, the share of coal in America’s electricity mix is still above 15%, more than any renewable energy source.
All renewable energy sources combined—wind, solar, hydropower, biomass, and geothermal—surpassed coal-fired generation in the U.S. electric power sector for the first time in 2022. But coal still holds about a 16% share of electricity generation, more than wind’s share of around 11%, hydropower’s 6%, or solar power’s 4% share of the electric generation mix. READ MORE...
