EPA's Climate Plan for Power Plants Faces Legal Challenges and Grid Threats.

The Environmental Protection Agency has proposed a regulation that would require a 90% reduction in carbon dioxide emissions from the largest power plants by 2040, which would reduce carbon emissions by the equivalent of taking 137 million passenger vehicles off the road for one year. However, opponents are likely to sue to block the regulation, arguing that carbon capture and storage (CCS) isn't practical to require. The EPA counters that the declining cost and rapid growth of wind and solar power production mean that the industry can switch to renewables without meaningfully increasing costs.
