In 2025, New Hampshire's electricity consumption sees a significant reliance on low-carbon energy sources, with about 71% of electricity coming from these cleaner options. Notably, nuclear power stands out as the predominant source, contributing more than 55% to the state's electricity supply. Other low-carbon sources include hydropower, biofuels, wind, and solar, each contributing smaller portions, yet collectively proving essential in reducing reliance on fossil fuels. Fossil energy accounts for less than a third of the total electricity consumption, with natural gas being the main contributor. This diversification of low-carbon sources reflects New Hampshire's dedication to a cleaner, sustainable energy future aligned with climate goals.

Is Electricity Growing in New Hampshire?
Regarding electricity consumption trends, New Hampshire is experiencing a promising increase. In 2025, the average electricity consumption per person has reached approximately 13,928 kWh, breaking past records set in 2024. This growth highlights an increase of over 1,600 kWh per person compared to the previous year, indicating a rising demand likely driven by increased electrification and societal advancements. Parallelly, the per capita generation of low-carbon electricity has also surged, with 2025 figures marking an increase of 842 kWh above the previous high in 2023. These meaningful gains underscore an encouraging movement toward more sustainable, green energy practices while meeting growing consumption needs.
Suggestions
To further bolster low-carbon electricity generation, New Hampshire could benefit from expanding its nuclear capacity, given the existing infrastructure and significant contribution of nuclear energy. Drawing inspiration from other successful regions, the state could consider implementing strategies seen in states like Iowa and South Dakota, where wind power surpasses 50% of their electricity mix. Additionally, looking to Nevada and California, both of which have leveraged solar power to provide more than 30% of their electricity, could guide New Hampshire in scaling up its solar infrastructure. These examples illustrate tangible paths to diversifying and expanding low-carbon electricity sources, bridging the gap towards a more sustainable and pollution-free electricity future.
History
Tracing back the history of low-carbon electricity in New Hampshire reveals both advancements and challenges. Particularly, in the years leading to 2025, nuclear energy has shown signs of robust growth, with a noticeable increase in 2025 following a smaller uptick in 2024. However, hydroelectric and biofuel sources have seen slight fluctuations, with hydro experiencing minor declines in recent years. Despite these variations, the gains in nuclear capacity are pivotal, emphasizing the strategic importance of this energy source for New Hampshire's clean energy transition. The state's continued commitment to strengthening its nuclear presence and exploring additional solar and wind opportunities could ensure a sustainable trajectory for decades to come.
