The main source of electricity for Alaska is hydropower.

Hydropower is the primary source of electricity in Alaska, utilizing the state's abundant rivers and lakes to generate renewable energy. Hydroelectric plants harness the power of flowing water to produce electricity, serving many communities, especially in rural and remote areas. While oil and natural gas also contribute to the state’s energy needs, hydropower plays a key role in reducing reliance on fossil fuels. With a focus on sustainability, Alaska continues to invest in renewable energy sources like hydropower to support its growing demand for electricity while minimizing environmental impact.
