Solar and wind power pose a challenge for the U.S. electrical grid, which lacks the capacity to store surplus clean electricity and deliver it on demand. Researchers are developing grid-scale storage batteries, but the fossil fuel required to build these technologies could negate some of the environmental benefits of new solar and wind farms, say scientists.
