As of 2025, New Hampshire's electricity consumption landscape is significantly dominated by low-carbon sources. Low-carbon energy accounts for over two-thirds of the total electricity generation in the state. Within this category, nuclear energy stands out as the leading contributor, supplying more than half of the state’s electricity. Other low-carbon sources, although contributing a smaller share, include hydropower, biofuels, wind, and solar, each playing a crucial role in maintaining a clean energy mix. In contrast, fossil energy sources make up less than a third of the electricity generation, with natural gas as the primary fossil fuel at just over a quarter, followed by coal at nearly negligible levels.

Is Electricity Growing in New Hampshire?
The electricity consumption in New Hampshire has shown a marked increase, with the latest figures reaching 13,928 kWh per person, a notable improvement from the previous year's record of 12,281 kWh per person. This rise highlights a growing demand for electricity in the state, a positive indicator of economic and technological development. Alongside the overall growth, low-carbon electricity generation has progressed substantially, with the latest record standing at 9,842 kWh per person, surpassing the 2023 record by 842 kWh. This progress signifies New Hampshire's commitment to expanding its clean energy sources to meet the increasing demand sustainably.
Suggestions
To further elevate its low-carbon electricity generation, New Hampshire should prioritize expanding its existing nuclear infrastructure, given its substantial contribution to the current energy mix. Learning from regions renowned for their clean energy achievements, New Hampshire can draw inspiration from states like California and Nevada, where solar energy plays a significant role. Furthermore, fostering the development of wind energy could be informed by successes in states such as Iowa and South Dakota, which derive a substantial portion of their electricity from wind. These strategies would enable New Hampshire to harness the full potential of both nuclear and solar energy, transforming its energy landscape into a more sustainable and self-reliant system.
History
Reflecting on the historical trajectory of low-carbon electricity in New Hampshire, it is evident that significant development has occurred. Notably, in 2025, the state witnessed a remarkable increase in nuclear electricity generation, with an addition of 1.2 TWh. Concurrently, there was a minor increase in biofuels, contributing 0.1 TWh, while wind generation remained steady. However, the state experienced minor declines in hydropower in both 2024 and 2025. Despite these fluctuations, the recent history underscores the state's successful shift towards bolstering its low-carbon electricity sources, with nuclear energy playing a pivotal role in driving this transition. Looking ahead, continuing to bolster nuclear and solar capacity will be crucial for sustainable growth.
