Solar and wind are booming, while coal keeps shrinking

The boom in solar and wind power in the United States will deal a fresh blow to coal country in the next few years. Renewable energy, led by solar and wind, is projected to be the fastest-growing source of US electricity generation for at least the next two years, according to a report published Friday by the US Energy Department. Boosted by swiftly falling prices, utility-scale solar power is expected to increase by 10% in 2019 and 17% in 2020, the Energy Information Administration said. Wind power should grow 12% and 14% in those years, vaulting it ahead of hydropower for the first time.
