Alaska has large reserves of both oil and coal and plays a major role in U.S. energy.

Alaska is a key state in the U.S. energy landscape due to its substantial reserves of both oil and coal. The state is home to the Alaska North Slope, which contains significant oil fields, including the Prudhoe Bay Oil Field, one of the largest in North America. Additionally, Alaska has large coal deposits, especially in areas like the Matanuska-Susitna Valley and the Cook Inlet Basin. These resources contribute significantly to U.S. energy production, with Alaska playing a crucial role in oil supply, particularly for transportation fuels, while its coal is used for electricity generation and industrial applications.
