From June 2024 to May 2025, Ohio's electricity consumption predominantly relied on fossil energy, making up more than 70% of the total. Specifically, gas accounted for about half of this, with coal contributing roughly one-fifth. In contrast, low-carbon energy sources constituted slightly more than 16% of total electricity. Among the clean energy sources, nuclear energy had a significant role, contributing over 10%, complemented by solar, which contributed more than 3%, and wind, which made up close to 2%. Moreover, net imports also played a role by providing just over 12% of the state's electricity needs.
Is Electricity Growing in Ohio?
While Ohio's overall electricity consumption remains below its historic peak from 2007, recent trends highlight a shift towards greater clean energy generation. In 2025, the total electricity consumption per person in Ohio was approximately 13,849 kWh, which is down nearly 1,000 kWh from its peak in 2007. However, there is encouraging news on the low-carbon front. The latest figures show that each person in Ohio now benefits from around 2,240 kWh of clean electricity per year, which represents an improvement over the previous year's record of 2,156 kWh. This growth evidences a positive trend in the integration of more sustainable energy sources, although continued efforts are essential to fully realize Ohio's clean energy potential.
Suggestions
To sustainably increase Ohio's low-carbon electricity generation, further expansion of existing nuclear facilities could be invaluable, as nuclear power is a well-established, reliable source of clean energy in the state. Additionally, Ohio could benefit from adopting strategies similar to successful regions in both nuclear and solar energy development. For instance, states like South Carolina and Illinois, where nuclear energy provides over 50% of electricity, could serve as models for expanding nuclear contribution. In terms of solar energy, joint lessons can be gleaned from Lebanon and Nevada where solar electricity comprises about 30% and 29% respectively. By exploring such successful frameworks, Ohio can significantly advance its clean energy generation capacity.
History
Historically, Ohio's journey with low-carbon electricity, especially nuclear, has seen fluctuations. In the mid-2000s, there were alternations of gains and setbacks in nuclear electricity generation, with notable decreases in 2005 and 2007. Moving into the 2010s, the state experienced further ups and downs, including significant additions in 2012 and 2015. However, the subsequent decade saw more consistent challenges and reductions, notably in 2021 and 2022. Recently, there was a promising boost in solar energy in 2024 and 2025. These fluctuations underscore the need for sustained investments and policies to stabilize and increase low-carbon electricity generation, securing a steady, green energy future for Ohio.
