Over the past year, from June 2024 to May 2025, electricity consumption in South Carolina has seen an exciting shift towards low-carbon energy sources. More than half of the total electricity used in the state now comes from clean energy, with nuclear energy making up the lion's share at slightly over 53%. Although fossil fuels still play a significant role, accounting for nearly 40% of the energy mix, the presence of greener sources like solar, hydropower, and biofuels is encouraging. Solar energy, for example, contributes a modest 3% to the electricity mix, while hydropower adds close to 2%, and biofuels contribute nearly 2% as well. This trend demonstrates a clear commitment to greener energy solutions, although there is still work to be done in reducing reliance on fossil fuels like gas and coal, which together make up about 40% of the total electricity supply.
Is Electricity Growing in South Carolina?
Electricity consumption per person in South Carolina has seen a decline when compared to the historic high levels of 2005. The latest figures show an average of 18,463 kWh per person in 2025, which is a decrease of 5,544 kWh from 2005's peak consumption of 24,007 kWh per person. This dip in overall consumption contrasts with a similar decline in low-carbon electricity generation per person, down by 2,183 kWh from 13,276 kWh in 2005 to 11,093 kWh in 2025. While these figures may suggest stagnation, they underscore the potential and need for growth in low-carbon electricity production to meet future demands and support a sustainable energy transition.
Suggestions
Looking to the future, South Carolina can significantly boost its low-carbon electricity generation by expanding its existing nuclear facilities, as this form of energy already contributes significantly to the state's power supply. Drawing inspiration from regions that have successfully incorporated solar and wind energy can also provide pathways for improvement. For instance, the high percentage of wind energy in states like Iowa and South Dakota or the success of solar power in states like Nevada indicates potential strategies for South Carolina. Notably, countries like France have heavily invested in nuclear power, contributing almost 70% of their energy from this clean source. Learning from such examples, South Carolina can diversify and increase its electricity production portfolio by further integrating solar and exploring opportunities for wind power where feasible.
History
Reflecting on the history of low-carbon electricity in South Carolina, there have been notable fluctuations, particularly in nuclear energy production. Over the decades, there have been years of significant growth, such as 2007 and 2019, when nuclear power generation increased substantially. Conversely, periods of decline, observed in years like 2006 and 2018, highlight challenges that have tempered progress. Hydropower also experienced some growth, notably in 2009 and 2018, but has faced declines as well, such as in 2021. Despite these challenges, recent years show a renewed commitment, with nuclear power increasing again in 2023 and 2025. It's crucial for South Carolina to build on these gains by ensuring consistent investment in and optimization of its existing nuclear infrastructure and continually exploring innovative clean energy solutions.
