A diverse portfolio of energy fuels and sources helps maintain a secure, reliable and resilient energy grid. Renewable energy is becoming an increasingly important part of this energy generating mix, keeping costs down and reducing environmental impacts. In fact, according the US Energy Information Administration, by 2022 approximately 14% of the total electric generation in North Carolina was from renewable resources. The majority of the renewable energy generated in North Carolina is from solar, followed by hydroelectric power. In addition to the benefits noted above, renewable energy also provides long-term advantages toward a healthier environment. Most renewable energy generation sources have zero or low site-based environmental impacts such as NOx, SOx and GHG emissions. As the electric grid transitions toward being powered with a greater percentage of renewable energy generation, the state enjoys lower air emissions and reduced environmental impacts.
