From September 2024 to August 2025, Mississippi's electricity consumption relied predominantly on fossil fuels, with nearly 80% of its power coming from such sources. Natural gas accounted for a significant portion, making up approximately 75%, while coal contributed about 5%. Low-carbon energy sources, including nuclear, solar, and biofuels, made up the remaining 20% of the state's electricity. Of these low-carbon sources, nuclear was the largest contributor, supplying nearly 15% of the state’s electricity. Solar energy, though still relatively small, represented over 3% of the total consumption. It is vital for Mississippi to boost its clean energy production to reduce dependency on fossil fuels, which significantly impact environmental and public health aspects due to emissions and pollution.

Is Electricity Growing in Mississippi?
Electricity consumption in Mississippi is on the rise. In 2025, electricity usage reached 26,984 kWh per person, which is an increase of 707 kWh per person over the previous record in 2024. This growth trend is also evident in the low-carbon sector where generation increased to 5,402 kWh per person in 2025, marking an increase of 655 kWh per person compared to the previous year. This signifies a positive shift towards sustainable energy sources, yet more needs to be done to accelerate clean energy's share in the overall electricity mix to sustain this momentum and prepare for future energy needs.
Suggestions
To further promote low-carbon electricity generation, Mississippi should focus on expanding its existing nuclear capabilities, as this is already a significant part of their clean energy portfolio. Additionally, lessons can be learned from regions such as France and Slovakia, where nuclear power comprises over 65% of their electricity, and South Carolina in the U.S., where it contributes over half. Boosting solar energy is also crucial, with opportunities to draw inspiration from regions like Lebanon and Nevada, where solar accounts for around 30% of electricity. By following such examples, Mississippi can effectively harness a balanced mix of nuclear and solar power to drastically reduce its carbon footprint while meeting rising electricity demands.
History
The history of low-carbon electricity in Mississippi, specifically nuclear, has seen fluctuations over the decades. In the early years of the 21st century, nuclear energy production fluctuated with significant increases and decreases, notably in 2009 and 2013 with substantial growth, but also marked declines in 2012 and 2020. More encouraging trends have emerged in recent years, with steady gains such as in 2021 and positive contributions from new solar projects in 2024 and 2025. To continue this progress, Mississippi should strive for consistent growth in low-carbon sources, capitalizing on advancements in nuclear and solar technology to ensure a sustainable and reliable energy future.
