From July 2025 through June 2026, more than half of New Hampshire's electricity consumption—approximately 67%—is derived from low-carbon sources, with nuclear power representing a commanding 52% of the total. This notable reliance on nuclear energy highlights the state's substantial commitment to generating clean electricity. Beyond nuclear, hydroelectric power accounts for almost 7% of electricity consumption, playing a vital role in maintaining a sustainable energy mix. However, wind and solar energies individually contribute less than 3%, each supplying around 2.3% of the total electricity used, indicating areas where further development could diversify and strengthen the low-carbon landscape. Meanwhile, fossil fuels continue to play a significant role, supplying nearly a third—weighing in at about 32%—with natural gas as the dominant fossil source at roughly 31%.

Is Electricity Growing in New Hampshire?

The state of New Hampshire, unfortunately, is witnessing a decline in electricity consumption, with the latest per capita figure standing at 13,486 kWh, which represents a decrease of 442 kWh from the previous record in 2025. This downturn is mirrored in the generation of low-carbon electricity, which also dropped by 773 kWh per person compared to last year. These declines are concerning, especially considering the increasing need for sustainable electricity solutions to accommodate future demands driven by electrification and technological advancements like AI. The reduction in low-carbon production is particularly alarming due to its essential contribution towards combating climate change and air pollution caused by reliance on fossil fuels.

Suggestions

To enhance low-carbon electricity generation, New Hampshire should focus on expanding its already significant nuclear capabilities, as seen in states like France and Slovakia, where nuclear significantly contributes to low-carbon electricity. Furthermore, the state can learn from the successful deployment of solar power in states such as California and Nevada, where solar contributes more than 30% of the energy mix. New Hampshire could also benefit from emulating Iowa's robust wind electricity generation, presenting a viable opportunity for diversifying its low-carbon portfolio. By looking at these regions and investing in proven clean energy solutions—primarily nuclear and solar—New Hampshire could substantially boost its low-carbon electricity generation, setting a benchmark for clean energy progress.

History

Historically, New Hampshire's commitment to low-carbon electricity has seen various fluctuations. In 2024, there was a minor increase in nuclear generation, complemented by a slight decline in hydropower and biofuels, while wind electricity generation remained stable. The following year, a marked increase in nuclear electricity was recorded, aligning with modest biofuel growth, though hydroelectric power continued its gradual decline. Regrettably, 2026 experienced a significant setback, with a notable decrease of 1 TWh in nuclear generation, accompanied by continued diminishment in hydroelectric capacity. This regression in nuclear output, despite being an anomaly, underscores the need for robust strategies and investments to ensure a stable and expanding low-carbon future for the state.
