In Tennessee in 2025, the electricity consumption landscape offers a noteworthy mix of imported, fossil-based, and low-carbon energy sources. Net imports make up a substantial portion, at more than a third of the state's electricity supply. Low-carbon energy accounts for another third, demonstrating a solid effort towards clean energy adoption. This group includes nuclear power, representing a quarter of the state's electricity, hydropower with close to 7%, and a modest solar contribution, just above 1%. Fossil energy, primarily from coal and gas, makes up nearly a third of the total, with each accounting for around 15%. These figures suggest a balanced yet ambitious energy profile, with a significant emphasis on imported and fossil energy sources, highlighting an opportunity for further development of low-carbon electricity.

Is Electricity Growing in Tennessee?
Tennessee has observed an upward trend in electricity consumption, indicating growth in energy demand and economic activity. The average electricity use per person in 2025 has surpassed previous records, reaching nearly 16,000 kWh per person, an increase of 647 kWh per person from the year before. However, while overall electricity consumption grows, the generation of low-carbon electricity has seen a decline. Current low-carbon generation stands at 5,347 kWh per person, a decrease of 1,218 kWh compared to the 2023 figures. This reduction in clean energy generation is a concerning trend that requires immediate attention to ensure sustainable energy growth aligns with increased consumption.
Suggestions
To enhance its low-carbon electricity generation, Tennessee should focus on expanding its nuclear capabilities and exploring solar energy potential. Building on its established nuclear infrastructure is critical, especially considering regions like France and Slovakia, where nuclear power contributes over 65% to the energy mix. States like South Carolina and Illinois also serve as excellent examples, with significant portions of their electricity coming from nuclear energy. Additionally, expanding solar power, drawing inspiration from Nevada and California, where solar energy accounts for over 30% of their electricity, could provide a sustainable boost to Tennessee's clean energy production. Emulating these successful regions could position Tennessee as a leader in low-carbon electricity, reducing reliance on imported and fossil energy sources.
History
Over the decades, the history of low-carbon electricity in Tennessee reflects both growth and challenges. During the early 2020s, nuclear energy faced setbacks, particularly in 2024 and 2025, with significant reductions of approximately 5.8 TWh and 2.9 TWh, respectively. However, hydropower saw a modest increase in 2024. These fluctuations indicate the dynamic nature of Tennessee's energy landscape, underscoring the need for strategic investments in reliable, low-carbon energy sources, such as nuclear and solar, to ensure a stable and greener energy future. By addressing past declines and emphasizing growth in clean energy generation, Tennessee can play a pivotal role in the transition toward a more sustainable and environmentally friendly energy system.
