Duke Energy President and CEO Lynn Good called the plan "ambitious," saying in a statement that it "seeks to build on the substantial progress Duke Energy and other utilities have made to reduce our environmental footprint. Even without federal regulations, our company has reduced carbon dioxide emissions from our power plants by 22 percent since 2005. As we continue to move to a lower carbon future, we will also continue to work constructively with states to identify customer solutions that preserve the reliability and affordability that our communities expect. As we continue to modernize our system, energy diversity will be important – nuclear, natural gas, state-of-the-art coal, hydro, renewables, energy efficiency and energy storage."
