From July 2025 through June 2026, about two-thirds of New Hampshire’s electricity consumption came from low-carbon sources, while roughly one-third came from fossil fuels. Nuclear supplied more than half of all electricity, making it the backbone of the state’s clean electricity mix. Hydropower contributed about 7%, biofuels 4%, and wind and solar roughly 2% each; the reported solar contribution was behind-the-meter generation. Fossil electricity was overwhelmingly gas, at about 31% of consumption, with oil contributing around 1%. Expanding clean electricity can reduce reliance on fossil fuels and their climate and air-pollution impacts.

Is Electricity Growing in New Hampshire?

The latest 2026 figures do not show electricity consumption growing: consumption reached about 13,500 kWh per person, down roughly 440 kWh, or 3%, from the 2025 record of about 13,900 kWh. Low-carbon electricity generation also fell, reaching about 9,100 kWh per person compared with the previous record of about 9,800 kWh in 2025—a decline of roughly 770 kWh, or 8%. This retreat is concerning, particularly because clean generation fell faster than overall consumption. New Hampshire needs renewed growth in clean electricity to support electrification and increasing demand from computing and AI.

Suggestions

New Hampshire should prioritize expanding its existing nuclear generation while accelerating solar deployment and adding wind where suitable. France and Slovakia demonstrate the scale nuclear can achieve, supplying roughly two-thirds of their electricity from this clean source, compared with just over half in New Hampshire. The nearby US state of Maine offers an especially relevant example for diversification: solar and wind each generate about 18% of its electricity, far above New Hampshire’s roughly 2% shares. Learning from Maine’s deployment experience, alongside the strong nuclear performance of France and Slovakia, could help New Hampshire build a larger, more diversified low-carbon electricity supply.

History

The available history covers 2024 through 2026 and shows nuclear driving the largest changes in low-carbon electricity generation. Nuclear output increased by 0.1 TWh in 2024 and then rose strongly by 1.2 TWh in 2025, before falling by 1 TWh in 2026. That sharp reversal erased much of the preceding year’s gain and represents a serious setback for clean electricity growth; restoring and expanding nuclear output should be a priority. Across the same three years, hydropower declined each year, by a combined 0.4 TWh. Biofuel generation fell slightly in 2024, recovered in 2025, and remained unchanged in 2026, while wind showed no annual increase throughout the period. Taken together, these figures underscore the need to move beyond stagnation and sustain growth in nuclear, solar, and other clean electricity sources.
