A coalition of more than 180 scientists and sustainability scholars from across Iowa has issued a collective call urging the state to accelerate the rollout of renewable energy infrastructure. The experts emphasize that expanding clean power is essential to satisfy the region's rapidly growing electricity requirements.
The appeal, articulated in the newly released 2026 Iowa climate statement, warns that the state has reached a defining fork in the road. Decision-makers must choose between continuing the expansion of clean energy resources or constructing new fossil-fuel-burning generating stations to accommodate rising electrical consumption.
The authors of the statement stressed that the mounting pressure on the electric grid requires immediate and coordinated action across multiple sectors. They noted that the responsibility to champion cleaner power rests not only with utility executives, but also with technology leaders, local elected officials, and everyday residents.
According to the academic coalition, stakeholders must actively pursue generation sources that are cleaner, more cost-effective, and more efficient. The group also cautioned that the state must confront and dismantle policy and regulatory hurdles designed specifically to obstruct the growth of renewable energy projects.
David Courard-Hauri, a professor of environmental science and policy at Drake University, outlined the compounding environmental pressures confronting the region. He noted during a virtual press conference that Iowa is experiencing hotter summer seasons alongside more erratic patterns of drought, severe storm activity, and localized flooding.
At the same time, the state is seeing a substantial increase in the construction and operation of data centers. Courard-Hauri pointed out that this influx of high-demand infrastructure makes the present moment a crucial turning point for determining Iowa’s long-term energy strategy.
The Drake University professor questioned whether utilities and major technology corporations should continue building on Iowa’s established leadership in clean power, or whether they will revert to fossil fuel facilities. He emphasized that fossil generation carries significant climate consequences, public health impacts, and the burden of fuel price volatility that consumers have experienced.
The scientists’ warning follows a recent findings report from the Iowa Environmental Council showing an unexpected shift in generation sources. In 2025, the proportion of electricity generated from coal increased in the state for the first time in several years, interrupting a sustained period of decline.
The environmental council’s findings called for an immediate acceleration in the installation of solar arrays, wind turbines, and utility-scale battery storage. The organization stressed that these zero-carbon resources are vital if the state is to meet its broader objective of reaching carbon neutrality by 2050.
Power companies in the region, which continue to build out their own wind and solar assets, offered a different perspective on the challenge. Utility representatives stated that environmental targets and independent reports often fail to account for the complex operational balance required to guarantee electrical reliability while keeping consumer rates affordable.
Grid-level forecasts show that regional power demand is expanding at an unprecedented rate. The Midcontinent Independent System Operator, known as MISO, noted that electricity peak load across its footprint remained largely flat between 2009 and 2024, but current market developments have dramatically shifted that trajectory upward.
MISO, which oversees grid reliability across broad portions of the Midwest and parts of the South, attributes the rapid increase in demand to several overlapping technological and industrial trends. These drivers include the rapid proliferation of artificial intelligence, high-density data centers, new and onshored industrial operations, electric vehicles, and building electrification.
The grid operator now projects a compound annual growth rate of 1.6% in peak electrical demand. Under this forecast, the annual coincident peak load across the MISO territory is expected to climb 38% higher by 2044 than the levels recorded in 2024.
Jacqueline Dowling, an assistant professor of civil and environmental engineering at the University of Iowa, highlighted Iowa’s historical foundation in clean energy. She noted that visionary policy decisions implemented two decades ago allowed the state to capitalize on wind and solar power, establishing Iowa among the nation's top states for renewable generation.
Dowling underscored that leaning further into a wind- and solar-dominant electricity system delivers multifaceted benefits. Beyond avoiding carbon emissions, she noted that relying on zero-fuel-cost renewables protects consumers from fuel price shocks and delivers substantial public health gains through improved air quality.
With electricity demand climbing swiftly, Dowling concluded that state leaders and power providers should seize the current window of opportunity to build out clean, economical, and dependable energy capacity rather than investing in legacy fossil fuels.
