A solar panel “fish” is seen amid a large array on Tiangang Lake in Jiangsu Province, eastern China. This solar project, which covers nearly half of the lake’s perimeter, is a combination of a fishery and a photovoltaic power plant with a capacity of 500,000 kilowatts. China added a reported 30 gigawatts of solar capacity in 2019, and solar was the only form of energy production that did not decline during the nation’s coronavirus lockdown in January and February 2020.
