Great progress has been made in the industry's efforts to reduce the environmental impact of electricity generation, even as demand for electricity increases.
The U.S. electric power sector has reduced air emissions substantially under existing programs.
- Since 1990, the industry has cut sulfur dioxide (SO2) emissions by 79 percent and nitrogen oxides (NOX) emissions by 76 percent.
- Over the past 30 years, ozone emissions in the eastern United States have been cut by 80 percent. These efforts also have cut emissions of mercury by about 50 percent. Electricity use increased 79 percent during this time period.
The power sector is regulated under many Clean Air Act programs:
