In the 12 months from June 2024 to May 2025, Alaska's electricity consumption prominently relied on fossil fuels, comprising over two-thirds of its energy mix. Fossil sources like gas and oil accounted for major shares, with gas representing more than two-fifths and oil contributing around 15%. On the cleaner side, low-carbon energy sources played a significant role, making up almost a third of the electricity generation. Hydropower was the dominant low-carbon source, providing close to this entire share. However, contributions from wind were limited, accounting for close to none of the total electricity generated, highlighting an area with potential for considerable improvement.
Is Electricity Growing in Alaska?
Electricity consumption per person in Alaska has seen a decrease since its peak in 2007, going from 10,027 kWh/person down to 8,598 kWh/person in 2025, a reduction of 1,429 kWh/person. Despite the decline in overall consumption, there has been modest progress in low-carbon electricity generation, now standing at 2,678 kWh/person—43 kWh more than the previous record set in 2020. While this indicates some advancement towards embracing cleaner energy, it emphasizes the urgent need for Alaska to expand this positive trend to ensure future sustainability and reduce reliance on fossil fuels.
Suggestions
To enhance low-carbon electricity generation, Alaska could take inspiration from regions that have successfully shifted towards sustainable sources. States like Iowa and South Dakota have harnessed wind energy extensively, producing over half of their electricity from wind. Likewise, the nuclear capabilities of countries like France, where nuclear energy constitutes more than two-thirds of the electricity generation, underscore the potential for significant clean energy contributions. Moreover, integrating solar, as seen in regions like Nevada with nearly a third of its electricity generated from this source, can provide Alaska with a diverse, clean energy mix, reducing environmental impacts and promoting a resilient energy future.
History
Historically, Alaska's low-carbon electricity generation has largely been due to hydropower, with changes over the years showing relatively stable output. From the mid-2000s onward, hydroelectric output fluctuated slightly with minor increases and decreases, though it remained a consistent low-carbon energy source. The introduction and growth of wind power began in 2013, marking a positive step towards diversity in clean energy sources. However, consistent and considerable investments in more expansive green electricity sources, such as nuclear and solar, remain crucial for Alaska to significantly enhance its clean energy generation, ensuring a sustainable and environmentally friendly energy portfolio for the future.
