Climate Change & The Environment
As one of the largest electric utilities in the United States and a large consumer of fossil fuels, we strive to reduce the environmental impact of our operations while providing reliable, reasonably priced electricity for our customers. Climate change remains a significant sustainability issue for AEP and one of our most challenging.
We believe climate change is a global issue that requires a global solution and cannot be effectively addressed through the existing mechanisms available under the Clean Air Act, including the piecemeal adoption of new source performance standards for specific industries. As the U.S. Environmental Protection Agency moves forward with regulations designed specifically to reduce greenhouse gas emissions from coal-fueled power plants, we will participate in the discussions and work to ensure that regulations addressing climate change are reasonable and reflect the current state of emissions-reducing technologies. We also will strive to ensure that regulations take into account the emission reductions already achieved through the transition of our nation’s electricity generation fleet.
Between 2005 and 2013, AEP reduced its carbon dioxide emissions by 21 percent. The company also reduced sulfur dioxide and nitrogen oxide emissions by more than 80 percent each since 1990, and reduced mercury emissions by nearly 60 percent since 2001. As we retire an additional 6,500 MW of older coal capacity and complete retrofit projects on an additional 5,400 MW of coal capacity during the next two years, these emissions will continue to decline.
Balancing Our Mix of Fossil Fuels
Abundant, low-cost natural gas, combined with new regulations on coal-fueled power plants, are resulting in an increasingly diverse generation fleet for AEP. Our use of coal to generate electricity will decrease in the coming years and our use of natural gas will increase. The remainder of our generating capacity will consist of nuclear, hydro, renewables, and energy efficiency and demand response programs. By 2026, we project that our coal-fueled generating capacity will drop to 49 percent, while natural gas capacity increases to 28 percent.
Because the stability of the electricity grid depends in part on reliable base load capacity that responds effectively to unexpected changes in load or other conditions, we continue to investigate technologies that can supply affordable and reliable base load generation while improving environmental performance. We also are actively engaged in developing advanced electric storage technology and expanding our transmission infrastructure to allow greater integration of renewable and other intermittent resources on the grid.
How We're Addressing Climate Change
Although we'll remain a large consumer of fossil fuels, the changes in our generation fleet will further reduce our future carbon dioxide emissions. Our goal for 2020 is to reduce our greenhouse gas emissions by 10 percent from 2010 levels.
We've proactively supported a number of climate change public policy initiatives. We've also made significant investments in clean-coal technologies including carbon capture and storage. Additionally, we continue to increase our use of renewable resources such as wind and solar, and continue to ramp up energy efficiency and demand response programs where there is regulatory support.
