In 2025, the landscape of electricity consumption in Alaska presented a mix of fossil and low-carbon energy sources. More than half of the electricity consumed, around 64%, was derived from fossil fuels, with gas leading at approximately 37%, followed by oil and coal at 15% and 12%, respectively. Low-carbon energy contributed to roughly 31% of Alaska's electricity needs. Hydropower was the most significant contributor within this category, accounting for over 27%, while wind energy accounted for a small fraction, close to 2%. Notably, electricity imported from external sources constituted almost 4% of the total consumption. Despite the reliance on fossil fuels, there is a significant presence of low-carbon sources which are crucial for reducing carbon emissions and achieving sustainability.

Is Electricity Growing in Alaska?
Examining the trends in electricity consumption in Alaska reveals a concerning stagnation. The latest per-person consumption stood at 9077 kWh, a slight decrease from the 2023 figure of 9146 kWh per person, marking a decline of 69 kWh. However, there is a glimmer of hope in the low-carbon sector, which experienced growth. In 2025, per-person low-carbon electricity generation reached 2774 kWh, surpassing the 2023 record by 137 kWh per person. This growth in clean energy is a positive indicator, demonstrating Alaska's potential to shift towards greener energy sources, albeit the overall electricity consumption trend should be reversed to accommodate increasing demands from population growth and technological advancements like AI.
Suggestions
Alaska can enhance its low-carbon electricity generation by taking cues from regions excelling in nuclear and wind energy. States such as Iowa and South Dakota have achieved significant wind generation, around 58%, which can provide a pathway for Alaska to exploit its wind resources more effectively. Moreover, global leaders like France and Slovakia, which acquire over 65% of their electricity from nuclear power, exemplify how nuclear energy can provide a steady and reliable low-carbon electricity supply. Investing in solar power, supported by advances seen in countries like North Macedonia (49%) and states like Nevada (34%), can further diversify and reinforce Alaska’s clean energy strategy. Embracing a balanced mix of nuclear, wind, and solar energies will not only propel Alaska toward a sustainable future but also bolster its electricity grid against reliance on fossil fuels and their associated environmental impacts.
History
Reflecting on the history of low-carbon electricity in Alaska unveils modest fluctuations in recent years. In 2024, hydroelectric power experienced a minor decline by 0.1 TWh, while wind and biofuels maintained their levels, indicating stability. The year 2025 saw an increase in hydro power by a similar magnitude of 0.1 TWh, while wind and biofuels remained unchanged. This stability, however, should be viewed as a call to action to aggressively pursue growth in clean energy. The consistency in wind and biofuel generation suggests an opportunity for expansion, and the slight increase in hydroelectric power marks a positive movement, albeit minimal, towards boosting Alaska's low-carbon electricity generation. With more effort, Alaska could replicate the success seen in other regions by investing strategically in scalable and efficient low-carbon energy sources such as solar and nuclear power.
