Aging is a fact of life, for people and equipment alike. But the negative impact of aging on wind and solar power plants is being reduced thanks to maturing technologies and commercial practices. Researchers at Berkeley Lab have taken a new look at how wind and solar generators are performing in the field, leveraging data from the sizable U.S. utility-scale wind and solar fleets.
