In 2025, South Carolina's electricity generation paints a promising picture for low-carbon energy. More than half of the electricity in South Carolina is generated from nuclear energy, which accounts for a significant portion of the state's low-carbon sources. Fossil fuels, however, still contribute nearly 39% of the electricity mix, with gas and coal fairly balanced in their share. Solar energy is contributing just shy of 4%, with utility-scale solar making up the majority of that. Additionally, biofuels and hydropower round out the low-carbon side, contributing marginally. This division highlights the state's reliance on fossil fuels, albeit a significant push toward cleaner options is noteworthy.

Is Electricity Growing in South Carolina?
Examining the figures reveals a slight increase in electricity consumption per person in South Carolina, from 18,828 kWh in 2023 to 18,912 kWh in 2025, marking a small growth of 84 kWh. However, low-carbon electricity per person experienced a diminutive decline of 9 kWh during the same period. Although total electricity generation is on the rise, the stagnation in low-carbon electricity is concerning, given its importance in combating climate change and reducing pollution. This trend underscores the need for stronger actions to promote and expand clean electricity sources to meet future demands and support a cleaner environment.
Suggestions
To effectively boost low-carbon electricity generation, South Carolina should focus on expanding its nuclear energy capacity, building on its already substantial nuclear energy utilization. Taking cues from France and Slovakia, which rely heavily on nuclear energy for their low-carbon electricity, can illuminate pathways for development. Furthermore, looking at regions like Nevada and California, where solar production is high, introduces opportunities to increase solar energy shares in South Carolina. By investing in these technologies, the state can lead the way in green energy progress while reducing its dependence on fossil fuels, which are contributing to climate change and air pollution.
History
Historically, low-carbon energy generation in South Carolina has experienced fluctuations, notably in nuclear electricity. In 2024, nuclear saw a notable decline by 1.9 TWh, yet it rebounded impressively in 2025, adding 2.9 TWh, signaling robust advances in nuclear energy deployment. Meanwhile, small positive changes in hydro and biofuels from 2024 persisted into 2025, despite a slight reduction in biofuels. These shifts reflect a clear determination towards enhancing low-carbon electricity generation, specifically through nuclear advancements, underscoring its role as a cornerstone of the state’s clean energy strategy.
