Our power generation fleet is one of the cleanest and lowest-cost in the nation, including nuclear, natural gas, landfill gas, hydro, wind, and solar. We're also developing fuel cell projects, zero-emission natural gas plants, microgrids, and other fresh, transformational ideas. Exelon believes in an integrated grid that combines both existing clean power facilities and new, distributed generation technologies. As we move toward a cleaner energy future, all sources of power will coexist.
