In examining the state of electricity consumption in South Carolina from April 2025 to March 2026, it's evident that more than half the electricity comes from low-carbon sources. Nuclear energy leads this group by generating over 53%, contributing the most significant share to the state’s clean electricity. While solar energy and hydropower combine to add around 6%, they still play a crucial role in the overall mix. On the other hand, fossil fuels account for nearly 40%, with natural gas and coal making up the most substantial portions of this category, at roughly 22% and 17% respectively. Efforts to increase the share of clean electricity will not only reduce carbon emissions but also pave the way for a more sustainable energy future in the state.

Is Electricity Growing in South Carolina?

Looking at electricity consumption patterns, South Carolina has witnessed a slight decrease. The most recent figures in 2026 show a consumption of just over 18,700 kWh per person, a small reduction from their 2025 high of nearly 18,900 kWh per person. Similarly, low-carbon electricity generation has slightly decreased compared to the past. With electricity from clean sources falling from its 2023 peak of about 11,600 kWh per person to approximately 11,400 kWh per person, there is a concern about reaching sustainability targets. This stagnation hints at the urgent need for strategic interventions to boost both overall and clean electricity generation.

Suggestions

To bolster low-carbon electricity generation, expanding existing nuclear facilities could be a practical step for South Carolina, given that nuclear energy already forms a substantial part of the state's electricity mix. Additionally, learning from other successful regions could offer valuable insights. For instance, Nevada and California have made impressive strides in solar energy, accounting for around 30% of their electricity consumption. Similarly, the state can look at how France has managed to procure 67% of its electricity from nuclear energy. By adopting similar strategies and leveraging local resources, South Carolina could further increase its low-carbon electricity share, helping to reduce its carbon footprint and promoting environmental stewardship.

History

Reflecting on the historical trends of low-carbon electricity generation in South Carolina reveals some fluctuations over the years. In 2024, nuclear generation experienced a significant decline, impacting the clean energy sector. However, it was quickly followed by a recovery in 2025, marking a substantial increase in nuclear electricity. During this period, there were modest gains in hydropower and biofuels, too, although these were not as prominent as the changes in nuclear energy. The slight reduction in nuclear generation in 2026, paired with minor adjustments in hydropower and biofuels, highlights the volatilities that can affect electricity production. This history underscores the importance of consistent investments and policies to ensure a stable increase in low-carbon electricity, vital for reducing reliance on fossil fuels and setting a precedent for green energy growth.
