MidAmerican Energy serves the energy needs of more than 1.6 million customers in Iowa, Illinois, Nebraska and South Dakota. Our company is part of the Berkshire Hathaway Energy family of businesses. We are a rate-regulated utility, with electric rates 42% below the national average according to the Energy Information Administration.
MidAmerican has invested nearly $15 billion in renewable energy projects across Iowa. We currently have more wind generation capacity than any other investor-owned utility in the United States. Since 2020, our renewable energy sources have delivered an average of 90% of our Iowa customers' annual electricity needs. Plus, our unique GreenAdvantage® program, allows our Iowa customers to claim the annual renewable energy percentage to help them reach their sustainability goals. 
MidAmerican has retired five of its 11 coal units and as of year-end 2023, and we have reduced our CO2 emissions by 41% since 2005.
To finance a portion of our renewable energy development in Iowa, we have issued green bonds to investors totaling $6.35 billion. For more information on MidAmerican's renewable strategy, see slides 86-95 of Berkshire Hathaway Energy's 2024 Fixed-Income Investor Conference presentation
