More than 180 scientists and sustainability scholars from academic institutions and organizations across Iowa are urging state leaders, businesses, and residents to accelerate the development of renewable power generation to satisfy rapidly expanding electricity requirements.
The collaborative call to action was outlined in the 2026 Iowa climate statement released Tuesday. In their assessment, the researchers emphasized that the state has arrived at a critical crossroads, facing a definitive choice between expanding clean energy infrastructure or constructing new fossil fuel facilities to address mounting electrical loads.
The authors argued that the urgency of the moment requires participation from all sectors of society. They called upon everyday citizens, technology executives, local policymakers, and utility leaders to actively champion and implement cleaner, more economical, and more efficient methods for electricity generation.
The coalition also pressed decision-makers to remove regulatory and institutional obstacles that have hindered the deployment of clean energy systems across the region. They stressed that artificial impediments should not be permitted to slow down renewable transitions at such a crucial juncture.
Speaking during a virtual press conference, David Courard-Hauri, a professor of environmental science and policy at Drake University, emphasized the compounding environmental challenges facing the state. He noted that Iowa is experiencing rising summer temperatures, altered precipitation patterns resulting in droughts and severe flooding, and an increased frequency of extreme storm systems.
At the same time, Courard-Hauri pointed out that Iowa has witnessed a notable proliferation of energy-intensive data centers. This rapid corporate expansion has amplified electricity consumption and intensified the debate surrounding how the state should power its economic future.
Courard-Hauri raised fundamental questions regarding whether utilities and commercial developers should maintain Iowa's established leadership in renewable development or revert to fossil-fueled generation. He cautioned that relying on fossil plants would expose the public to heightened health risks, environmental damage, and volatile energy prices.
The researchers highlighted findings from a recent report by the Iowa Environmental Council, which revealed a concerning shift in the state's energy mix. According to the council's data, the proportion of electricity produced from coal-fired generation increased in 2025, marking the first such upward trend after multiple years of decline.
To counter this trajectory, the environmental council’s findings called for an immediate acceleration in the installation of wind turbines, solar arrays, and large-scale battery storage systems. Such investments, the report maintained, are essential if the state hopes to achieve net-zero carbon targets by 2050.
Regional utility companies have responded by defending their broader operational strategies. While noting their ongoing expansions in solar and wind capacity, utilities contended that advocacy reports often overlook the intricate technical challenges associated with maintaining grid reliability and consumer affordability alongside environmental objectives.
Broad power grid forecasts indicate that electricity demand will continue its steep ascent. The Midcontinent Independent System Operator, the regional transmission organization known as MISO, noted in a 2024 analysis that peak electrical load had remained largely flat across its footprint between 2009 and 2024 before experiencing a sharp shift.
MISO attributed this reversal to several structural developments occurring in rapid succession. The primary drivers include the boom in artificial intelligence computational facilities, large-scale data centers, domestic manufacturing reshoring, electric vehicle adoption, and the widespread electrification of residential and commercial buildings.
Under MISO's projections, peak electricity demand is expected to climb at a compound annual growth rate of 1.6 percent. Over the twenty-year period between 2024 and 2044, this steady growth is forecast to push annual coincident peak demand 38 percent higher than 2024 levels across the Midwestern and Southern regions covered by the grid operator.
Jacqueline Dowling, an assistant professor of civil and environmental engineering at the University of Iowa, noted that Iowa's forward-looking policies established two decades ago successfully turned the state into a national leader in renewable power. She pointed out that Iowa consistently ranks near the top of nationwide rankings for clean energy production.
Dowling emphasized that doubling down on wind and solar power provides substantial, multifaceted advantages. These include better public health outcomes from cleaner air quality, lower long-term consumer rates resulting from zero-fuel-cost generation, and critical progress toward mitigating global carbon emissions.
The researchers concluded that as utilities rush to add significant generation capacity in the coming years, policymakers and industry stakeholders should seize the opportunity to prioritize low-cost, secure, and emission-free renewable resources rather than returning to legacy fossil fuels.
