In the year 2025, Mississippi's electricity consumption is predominantly sourced from fossil fuels, accounting for approximately four-fifths of the total. Natural gas contributes the lion's share, with almost 74%, while coal provides about 5%. On the other hand, low-carbon or clean energy sources constitute a bit more than a fifth of the electricity supply. Nuclear energy plays a significant role here, providing nearly 15%, while solar power, including utility-scale projects, offers nearly 4%. Biofuels contribute a small fraction but are not currently a focus for expansion when compared to the larger roles nuclear and solar can potentially play in the future.

Is Electricity Growing in Mississippi?
Electricity consumption in Mississippi is on an upward trajectory, reaching 26,619 kWh per person in 2025, surpassing the previous year’s record of 26,288 kWh per person by 331 kWh. This growth reflects not only an increased demand for electricity but also a stronger shift towards low-carbon energy sources. Low-carbon electricity generation witnessed a commendable increase, setting a new record of 5527 kWh per person, up by 769 kWh from the 2024 figure. This growing shift showcases Mississippi's potential to further embrace clean energy alternatives, which can significantly reduce reliance on fossil fuels.
Suggestions
To further increase low-carbon electricity generation, Mississippi could prioritize the expansion of its nuclear capacity, given its substantial contribution to the current energy mix. Such development could draw inspirations from successful regions, such as New Hampshire and South Carolina, where nuclear energy constitutes over half of their electricity production. In parallel, expanding solar power is also crucial. Observing Nevada and California, where solar energy forms a significant portion of their electricity supply, provides practical models on scaling solar infrastructure. By learning from these regions, Mississippi can effectively boost its clean electricity generation, align with sustainability goals, and reduce its carbon footprint.
History
Reflecting on recent history, Mississippi's low-carbon electricity generation has experienced notable shifts. While 2024 saw a decline in nuclear generation by 1.1 TWh and slight reductions in biofuels, the year 2025 marked a promising turnaround. Nuclear energy rebounded with a gain of 0.8 TWh, accompanied by a modest introduction of wind power. These developments symbolize a positive shift towards clean electricity, emphasizing the importance of maintaining and expanding these efforts to secure a sustainable energy future for Mississippi.
