Synapse released a report on Wednesday based on the latest version of its Coal Asset Valuation Tool (CAVT), which shows that the United States could save roughly $262 billion over the next three decades by shutting down a significant portion of its coal plants and replacing them with less expensive alternatives. The report demonstrates how a variety of factors, including aging infrastructure, more stringent environmental regulations, and lower natural gas prices, are converging to make the majority of coal plants uneconomic.
