A coalition of more than 180 scientists and sustainability researchers from academic institutions and organizations across Iowa is calling on the state to dramatically accelerate its investment in renewable energy infrastructure. The appeal comes in response to an unprecedented surge in electricity consumption driven by emerging technological and industrial demands.
In the newly released 2026 Iowa climate statement, the researchers warned that the state has reached a critical junction in its energy trajectory. According to the document, leaders and residents face a defining choice: either sustain the expansion of clean energy generation like wind and solar, or revert to constructing fossil-fuel-powered facilities to satisfy the rapidly escalating demand on the electric grid.
The collective statement emphasized that this moment requires active participation from every level of society. The authors urged individual citizens, technology company executives, municipal leaders, and power utility managers to advocate for generation methods that are cleaner, more cost-effective, and highly efficient, while actively dismantling obstacles that impede renewable energy growth.
The urgency of the situation was underscored during a virtual press conference by David Courard-Hauri, a professor of environmental science and policy at Drake University. He highlighted that Iowa is confronting an increasingly turbulent climate environment, characterized by hotter summer temperatures, recurrent droughts, heightened flood risks, and more severe storm occurrences.
Courard-Hauri noted that these environmental changes are coinciding with a rapid spread of energy-intensive data centers throughout Iowa. This convergence makes it an essential period for state leaders to determine the structural foundation of Iowa’s future energy supply.
Addressing the choices facing electric utilities and private tech developers building independent facilities, Courard-Hauri questioned whether the state will uphold its established track record in clean energy leadership or regress toward fossil fuels. He cautioned that relying on fossil generation carries substantial hazards, including adverse public health impacts, environmental damage, and the ongoing burden of fuel price volatility.
The scientists' warnings were reinforced by findings from a recent Iowa Environmental Council report, which documented a troubling shift in the state's power mix. For the first time in several years, the proportion of electricity generated from coal-fired power plants increased in 2025.
To reverse that trend and keep the state on track to achieve net-zero carbon emissions by the year 2050, the environmental report emphasized the necessity of deploying significant amounts of new wind, solar, and battery storage infrastructure across the state.
Electric utilities operating in Iowa, while continuing to build out local solar and wind installations, have expressed caution regarding rapid transition goals. Representatives from the utility sector noted that broad climate targets often fail to capture the intricate operational balance required to ensure round-the-clock grid reliability, protect consumers from rising costs, and maintain environmental sustainability.
The broader pressure on the power system is detailed in analyses from the Midcontinent Independent System Operator, the regional grid operator responsible for managing electricity transmission across large portions of the Midwest and parts of the South. Historical data from MISO indicates that regional peak electricity demand remained largely unchanged between 2009 and 2024.
However, grid officials reported that peak demand forecasts have suddenly surged due to the scale and speed of modern industrial changes. MISO identified several key catalysts behind the consumption spike, including the rapid expansion of artificial intelligence, high-density data centers, the electrification of building heating systems, the adoption of electric vehicles, and the return of domestic manufacturing operations.
Under MISO’s updated long-term forecasts, electricity peak demand across its multi-state footprint is projected to grow at a compound annual rate of 1.6 percent. This steady rise means that by 2044, annual peak demand is expected to climb 38 percent higher than the levels observed in 2024.
Jacqueline Dowling, an assistant professor of civil and environmental engineering at the University of Iowa, pointed out that the state’s current advantage stems from forward-thinking energy policies implemented over two decades ago. Those early initiatives propelled Iowa to become one of the top-performing states in the nation for renewable energy generation.
Dowling emphasized that reinforcing a power grid centered primarily around wind and solar provides tangible public health benefits through cleaner air quality. Additionally, renewable power offers long-term financial stability for consumers because renewable technologies eliminate ongoing fuel expenditures.
As electricity demand continues to accelerate rapidly, Dowling concluded that state policymakers and industry leaders should seize the opportunity to construct modern, secure, and cost-effective clean power systems rather than turning back to polluting alternatives.
