Voices Of 100%: Des Moines Commits To Clean Electricity Around The Clock

Originally published on 

Though it’s insulated from sea level rise, the state of Iowa faces many dangerous climate change impacts — which in turn threaten the nation’s food supply. Fortunately, the state is rich in renewable energy potential and eager advocates who hope to harness it.

For this episode of our Voices of 100% series of the Local Energy Rules Podcast, host John Farrell talks with Kari Carney and Josh Mandelbaum. Carney is the executive director of 1000 Friends of Iowa and Mandelbaum is a member of the Des Moines city council. The three discuss Des Moines’s round-the-clock clean electricity resolution, how it differs from traditional clean energy commitments, and the strategies Des Moines will use to reach its goal.

Listen to the full episode and explore more resources below — including a transcript and summary of the conversation.

Episode Transcript

Iowa Faces Climate Impacts, Too

Kari Carney is the Executive Director of 1000 Friends of Iowa, a non-profit organization “engaging local residents around responsible and equitable land use.” Part of responsible land use, says Carney, is considering its impact on the climate. Josh Mandelbaum, Senior Attorney at the Environmental Law & Policy Center, was elected to Des Moines City Council in 2017. Mandelbaum describes how he has already seen climate change impacts during his term on the council: flash flooding in 2018, a derecho storm in 2020, and a severe drought in 2021.

In 2021, Mandelbaum and his fellow council members unanimously passed a resolution for 100% clean electricity by 2035. Carney was among many advocates pushing for this resolution. The Des Moines resolution has one crucial clause: the electricity will come from renewable resources 24 hours a day, seven days a week.

Des Moines Citizens Task Force on Sustainability

On Earth Day of 2016, 1000 Friends of Iowa and others began lobbying for the creation of the Citizens Task Force on Sustainability. After meeting with members of the council and gaining the mayor’s support, the city approved the task force. Carney says that this step, and the grassroots mobilization and relationship building it took to accomplish it, got the ball rolling for the clean energy resolution.

“There were a number of different things that we did, but really it was building that grassroots support and continuing to push the rest of the council.” — Kari Carney

After Mandelbaum and others were elected to the city council in 2017, advocates pushed for what would become the 24/7 clean electricity resolution.

A New Kind of City Resolution

Des Moines’s 24/7 compact, also adopted by Ithaca, New York, was modeled after a similar pledge made by Google. Specifying a round-the-clock clean energy supply will lead to more local clean energy development, since the city cannot turn to renewable energy credits.

80% of Des Moines’s electricity, supplied by MidAmerican Energy, already comes from wind. However, MidAmerican greens some of its energy supply with renewable energy credits — which does not align with the Des Moines resolution. MidAmerican also, despite its 100% renewable energy vision, has no plans to retire its five coal plants. The city must therefore find a way to go above and beyond what the utility is willing to do.

“I have confidence that we can innovate and that we can continue to push forward, but we’re going to have to be pushing the utility. They don’t necessarily want to do it on their own, but we also know that they’re capable of doing it.” — Josh Mandelbaum

MidAmerican’s franchise agreement with Des Moines is up for renewal next year, says Mandelbaum, which gives the city some bargaining power.

The city’s first steps toward its goal have been benchmarking current energy and water use and hiring a sustainability director. Des Moines has also added solar to several new buildings, including a new fire station.

Energy Efficiency & Solar Offer an Avenue to Advance Equity

Both Carney and Mandelbaum emphasize the importance of energy efficiency in meeting Des Moines’s ambitious goal. Not only does energy efficiency have value in carbon reduction, but it makes electric bills more affordable and buildings more comfortable.

Energy efficiency is imperative for low-income residential customers, who face the greatest energy burden (portion of their income spent on energy). This is a challenge, since these same customers might not be able to afford the upfront costs of efficiency upgrades. Inclusive financing, sometimes called Pay As You Save, is one solution to this challenge.

Through inclusive financing, the utility pays for the efficiency improvement and the customer pays the utility back through their bill savings. Inclusive financing works for rental properties, as well, since the payments stay with the property.

“You can’t have affordable housing without energy efficiency.” — Josh Mandelbaum

Inclusive financing framework can also be used to install solar power.

Leading the Way for Iowa

Mandelbaum and Carney both describe cities and counties they have contacted or collaborated with. Since Des Moines makes up 10% of MidAmerican Energy’s customer base, says Mandelbaum, banding together with other MidAmerican customers will amplify the city’s voice.

Carney explains how other Iowa cities look to Des Moines as an example. She continues her outreach across the state, but accepts that Des Moines will pioneer the way for Iowa. Still, there are examples across the country that inspire Carney and other advocates — including the Minneapolis Clean Energy Partnership.

“We know Des Moines is definitely the leader, but others are interested in doing it. They just don’t want to be the first.” — Kari Carney

John directs the Democratic Energy program at ILSR and he focuses on energy policy developments that best expand the benefits of local ownership and dispersed generation of renewable energy. His seminal paper, Democratizing the Electricity System, describes how to blast the roadblocks to distributed renewable energy generation, and how such small-scale renewable energy projects are the key to the biggest strides in renewable energy development.   Farrell also authored the landmark report Energy Self-Reliant States, which serves as the definitive energy atlas for the United States, detailing the state-by-state renewable electricity generation potential. Farrell regularly provides discussion and analysis of distributed renewable energy policy on his blog, Energy Self-Reliant States (, and articles are regularly syndicated on Grist and Renewable Energy World.   John Farrell can also be found on Twitter @johnffarrell, or at
