New York (CNN Business) The simple laws of economics threaten to doom America's remaining coal power plants. That figure of at-risk coal plants in the United States rises to 86% by 2025 as solar and wind costs continue to plunge. The research demonstrates how it's increasingly more expensive to operate existing coal plants than build clean energy alternatives. "Nearly three-quarters of US coal plants are already 'zombie coal,' or the walking dead." Utility-scale solar power is expected to increase by 10% in 2019 alone, while wind power is expected to vault ahead of hydropower for the first time, the EIA said.
