In 2025, Iowa's electricity consumption reflected a strong inclination towards low-carbon energy sources. More than half of Iowa's electricity came from clean energy, with wind power contributing nearly 60% of the total electricity generated — a significant figure showing the state's commitment to sustainable sources. Although fossil fuels still played a role, accounting for around 37% of consumption, there is a clear trend towards reducing reliance on coal and gas. Coal made up about a quarter of the electricity, and gas contributed nearly 12%, while solar energy, though relatively modest at around 2.5%, also added to the low-carbon mix alongside wind and hydropower, which contributed about 1.5%.

Is Electricity Growing in Iowa?
Electricity consumption in Iowa has been on the rise, demonstrating a growing demand for power within the state. The latest figures for 2025 show electricity consumption at 23,032 kWh per person, marking an increase from the previous year's record of 21,886 kWh per person. This represents a notable growth trajectory with an increase of 1,146 kWh. Low-carbon electricity generation also set a new record, rising slightly from 14,397 kWh per person in 2024 to 14,452 kWh. The overall growth in electricity consumption underscores the dynamic evolution in Iowa’s energy landscape, yet the modest rise in low-carbon generation suggests the need for continued advancement in sustainable energy contributions.
Suggestions
To foster the expansion of low-carbon electricity generation, Iowa could prioritize further investment in its already successful wind power infrastructure. By examining regions with significant nuclear and solar contributions, Iowa can draw lessons to enhance its clean energy portfolio. For instance, states like Illinois, where nuclear energy contributes 50% to the mix, illustrate how expanding nuclear facilities can strengthen clean electricity generation. Meanwhile, Nevada and California, with solar percentages reaching over 30%, serve as examples of how solar expansion can greatly boost low-carbon electricity. By diversifying and expanding on these clean energy technologies, Iowa can meet its rising electricity demands while simultaneously reducing its carbon footprint.
History
The history of low-carbon electricity in Iowa has shown marked success but also highlights areas for improvement. In 2024, the state saw an increase of 2.8 TWh in wind generation, while hydropower only grew marginally, and biofuels did not change. However, 2025 brought a slight dip in wind power generation by 0.5 TWh, accompanied by stagnant growth in hydropower and biofuels. These patterns suggest that sustaining and advancing wind power, alongside exploring new avenues such as solar and nuclear, are crucial for maintaining a robust, green electricity network. With Iowa's present trajectory, the aim should be to build on past successes while proactively overcoming the stagnation seen in recent developments.
