    MidAmerican is focused on meeting our customers’ energy needs with cleaner generation and minimizing our impact on the environment.
    Since 2004, we have invested nearly $13 billion in renewable energy, allowing us to deliver clean and affordable energy to our customers. In fact, 83.6% of the energy our Iowa customers used in 2020 was from renewable sources – that’s our GreenAdvantage. As of year-end 2020, MidAmerican has reduced our CO2 emissions by 58% since 2005.

    As part of MidAmerican’s journey to a net-zero carbon future, we will invest in more renewable energy, such as solar and pumped hydro projects, and cleaner technologies, like battery storage and nuclear power. These investments will continue to climb as we strive to reach our 100% renewable energy vision.
     
    Wildlife and habitat protection are an essential part of our environmental efforts. We developed a Habitat Conservation Plan in partnership with landowners and the U.S. Fish and Wildlife Service, that outlines how we minimize and mitigate negative impacts our wind turbines or energy generation systems have on local ecosystems.

    In 1977, MidAmerican set aside 420 acres for the Big Sand Mound preserve after site evaluations identified an ecosystem not typically found in Iowa. Located south of Muscatine, Iowa, the preserve is a sand prairie ecosystem unlike any other in the Midwest that houses native plants and endangered animal species. Every three years, the preserve hosts a public field day to allow visitors in to study and observe this protected ecosystem.
     
    Energy efficiency is more than just making the most power with the least impact, it’s helping our customers use energy wisely to meet their needs while reducing their usage. Energy management will be an important part of a net-zero greenhouse gas emissions future. SummerSaver, our demand response program, helps protect our system and reduce usage during peak hours on the hottest days of the summer. Our energy efficiency rebates help customers save on energy-saving equipment, while programs like HomeCheck® Online help our customers evaluate their energy usage to make small changes to reduce energy consumption.

    Alongside Berkshire Hathaway Energy’s family of businesses, we are also striving for a net-zero greenhouse gas emissions future. Collectively, we aim to reach this sustainability goal in a way our customers can afford, regulators will allow and technology advances support. As of 2020, Berkshire Hathaway Energy has spent $34 billion on renewable energy, and has made commitments to spend an additional $2.5 billion by 2022. Learn more about these sustainability initiatives.

    MidAmerican knows that the future of transportation is electric. Electric vehicle (EV) adoption in the Midwest has lagged because of a lack of charging infrastructure. But we’re committed to changing that by building a network of more than 35 EV fast chargers across Iowa and offering rebates for EVs and chargers for our customers.
     
    Beyond personal vehicles, we’ve partnered with DART in Des Moines, MetroLINK in the Quad Cities and Iowa City Transit in Iowa City to add electric buses to their fleets. These 100% electric buses run on cleaner energy. Even bikes are running on clean energy! MidAmerican and the BCycle program brought electric bikes powered by wind and solar to downtown Des Moines in 2021.
