In 2025, electricity consumption in Mississippi heavily relies on fossil fuels, with more than three-quarters of its electricity coming from these sources. The largest share, close to three-quarters, is generated from gas, while coal only contributes to a bit more than 5%. On the other hand, low-carbon electricity sources make up slightly over one-fifth of the mix. Nuclear power stands out as the predominant low-carbon source, providing nearly 15% of the state's electricity. Solar energy, though still a smaller player, is making its mark with almost 4%, while biofuels contribute a modest 2%.

Is Electricity Growing in Mississippi?
Electricity consumption in Mississippi is on an upward trajectory. The latest figures for 2025 indicate a consumption of approximately 26,619 kWh per person, surpassing the previous record of 2024 by 331 kWh. This positive momentum is also evident in low-carbon electricity generation. It reached 5,527 kWh per person, highlighting a significant increase compared to 2024, with a jump of 769 kWh. This growth in low-carbon power is crucial to reducing reliance on fossil fuels.
Suggestions
To further increase low-carbon electricity generation, Mississippi can expand its existing nuclear power capabilities, tapping into its significant contribution and stable output. Learning from successful regions can also be beneficial. States like South Carolina and Illinois, where nuclear energy accounts for around half of electricity generation, provide excellent models to emulate. Additionally, looking towards solar power, Mississippi can draw inspiration from places like California and Nevada, where solar constitutes a substantial portion of electricity, at about 31% and 34% respectively. Embracing similar strategies can help Mississippi boost its clean energy footprint.
History
Reflecting on the historical shifts in low-carbon electricity in Mississippi, the recent years have shown a mix of encouraging growth and some setbacks. In 2024, there was a small decrease in nuclear power generation by 1.1 TWh, alongside a slight dip in biofuels. However, 2025 witnessed a positive turnaround with nuclear power rebounding by 0.8 TWh and wind energy increasing by 0.2 TWh. This underscores a positive trajectory for green energy, reinforcing the need for further investments in consistent and sustainable low-carbon sources like nuclear and solar to ensure a greener and more sustainable future.
