In 2025, New Hampshire's electricity profile is predominantly characterized by a strong emphasis on low-carbon energy sources. More than half of its electricity is generated from nuclear power, contributing to a total of about 71% of clean energy in the state's electricity mix. Hydropower, biofuels, and wind power add smaller yet significant portions to this clean energy composition, while solar energy, both large-scale and behind-the-meter, represents a steadily escalating share of the electricity generated. On the flip side, fossil energy sources still account for just under a third of the total electricity, with natural gas being the primary contributor and coal having a very minimal role. This balanced mix highlights the state's commitment to reducing reliance on fossil fuels and embracing sustainable electricity solutions.

Is Electricity Growing in New Hampshire?
Electricity consumption in New Hampshire is on an upward trend. As of the latest data from 2025, each person consumed an average of approximately 13,928 kWh, marking a significant increase from the previous record set in 2024. This growth of 1,647 kWh per person is mirrored in the rising generation of low-carbon electricity, which saw an increase of 842 kWh per person compared to 2023. The expansion of clean electricity underscores a promising trajectory toward a greener electricity framework, indicating both increased demand and a commitment to sustainable energy sources. Such a boost is crucial in supporting the electrification efforts aimed at reducing carbon footprints and meeting future energy needs.
Suggestions
To further enhance its low-carbon electricity generation, New Hampshire could capitalize on expanding its already significant nuclear capacity. Learning from successful regions, California and Nevada provide valuable insights with their substantial solar generation, which New Hampshire can emulate by increasing its solar energy initiatives. Similarly, looking at wind power frontrunners like Iowa and South Dakota, New Hampshire could explore the feasibility of bolstering wind energy production. By aligning with these strategies and expanding existing technologies like nuclear and solar, New Hampshire could further assert its leadership in clean electricity, ensuring a more sustainable and resilient energy future.
History
Historically, New Hampshire has seen varied progress in low-carbon electricity generation developments. In the mid-2020s, nuclear power witnessed a notable increase, particularly in 2025, with an added 1.2 TWh of electricity generation. This was accompanied by modest growth in biofuels and offset by a minor decline in hydropower. Such changes underscore the state's ongoing pursuit to enhance its clean electricity output. However, wind energy remained constant during this period, suggesting a potential area for strategic development. Overall, New Hampshire's historical shifts reflect an earnest dedication to transitioning toward a predominantly low-carbon electricity system, albeit with room for continued and intensified focus, particularly on expanding nuclear and solar technologies.
