The current state of electricity consumption in Mississippi shows a heavy reliance on fossil energy, which makes up more than three-quarters of the electricity generation, predominantly from gas. Low-carbon energy sources contribute a little over a fifth of the total, with nuclear energy being the most significant, responsible for almost 15% of the total electricity generated. Coal lags significantly behind, constituting just over 5% of the energy mix. Solar energy contributions are modest, at nearly 4%, mostly from utility-scale installations, while biofuels account for an even smaller fraction, close to 2%. This indicates room for growth in clean energy sources to promote a more sustainable energy mix moving forward.

Is Electricity Growing in Mississippi?
Electricity consumption in Mississippi is on the rise. The latest data from 2025 shows an increase to 26,619 kWh per person, up by 331 kWh from the previous year. Additionally, low-carbon electricity generation per person has jumped significantly from 4,758 kWh in 2024 to 5,527 kWh in 2025, marking an impressive 769 kWh increase. This steady growth in both overall electricity consumption and the share from low-carbon sources signals progress towards a cleaner energy future, driven by an encouraging uptake in sustainable energy technologies.
Suggestions
To further boost its low-carbon electricity generation, Mississippi can leverage its existing nuclear capacity, given its significant contribution to the state's energy mix. Learning from regions with robust low-carbon energy programs can be beneficial. For nuclear energy, Mississippi could look towards France and Slovakia, where nuclear comprises over 65% of electricity generation, or learn from South Carolina's success with nuclear energy accounting for 54% of its mix. In terms of solar power, Mississippi might gain insights from California, where solar constitutes 31% of their electricity, indicating potential for growth in the sunny regions of the state. Drawing on these examples, Mississippi can craft strategies to diversify and enhance its sustainable electricity generation capabilities.
History
The history of low-carbon electricity in Mississippi has seen varied developments over recent years. In 2024, there was a notable decline in nuclear electricity generation by 1.1 TWh, a concerning trend that warrants attention. Fortunately, 2025 has witnessed a positive turn with nuclear power making a comeback by 0.8 TWh and the introduction of new wind capacity adding 0.2 TWh. Biofuels, however, saw no change from the previous year, indicating a lack of growth. This trajectory underscores the importance of strategic investments in expanding nuclear and other clean energy technologies to ensure long-term energy sustainability and resilience against the challenges posed by continued reliance on fossil fuels.
