In Idaho, the current state of electricity consumption reflects a mix of various energy sources, with a significant share coming from low-carbon options. Over the 12-month period from April 2025 to March 2026, more than half of Idaho's electricity, specifically 56%, has been generated from low-carbon sources. Hydropower leads this group with roughly 37%, followed by wind at just over 10%, and solar power at nearly 7% when combining utility-scale and behind-the-meter generation. Interestingly, net imports contribute to almost a quarter of Idaho's electricity, while fossil energy, entirely from natural gas, makes up about 19%. The reliance on clean energy in Idaho is encouraging, with a clear dominance of low-carbon over fossil energy, reflective of a commitment to more sustainable power sources.

Is Electricity Growing in Idaho?

Considering recent changes, overall electricity consumption in Idaho seems to be experiencing a slight decline. The latest consumption figure stands at approximately 14,374 kWh per person, which is slightly lower than the previous peak of 14,503 kWh per person noted in 2025, reflecting a minor decrease of 128 kWh per person. However, there is a silver lining in the increased efficiency and generation of low-carbon electricity. The per-person low-carbon electricity generation has risen from 7,499 kWh in 2025 to 8,037 kWh at present, indicating a growth of 538 kWh and underscoring a positive trend towards cleaner electricity generation. This shift to higher low-carbon production is a crucial step in promoting a sustainable energy future in Idaho.

Suggestions

For Idaho to expand its low-carbon electricity generation further, focusing on the development of wind energy could be highly beneficial, given its already substantial contribution. Taking inspiration from successful regions, Idaho can learn from Iowa and South Dakota, where wind power comprises 57% and 55% of their electricity, respectively. Additionally, solar energy, while growing, could be further supported by looking at states like Nevada and California, where solar contributions are significant, at 34% and 31%. Importantly, exploring nuclear energy can provide a consistent and large-scale clean power option, as seen in France, Slovakia, Denmark, and other locations with high nuclear generation, often exceeding 50%. By following these examples, Idaho could significantly boost its clean electricity portfolio, reducing dependency on fossil fuels.

History

In recent years, Idaho has witnessed sustained growth in low-carbon electricity. Starting in 2024, hydropower grew substantially by 0.8 TWh and wind energy saw an increase of 0.7 TWh, indicating an expansion in these clean energy sources. In 2025, the trend continued with hydropower increasing by 0.6 TWh and a slight rise in wind energy as well, while biofuels saw a modest growth by 0.1 TWh. Entering 2026, hydropower further increased by 1.1 TWh, although wind energy remained constant compared to the previous year. These advancements in clean energy underscore Idaho's commitment to sustainable power generation and highlight the potential for continued growth in this sector. Overall, the state has demonstrated a strong trajectory toward enhancing its low-carbon electricity capacity.
