MidAmerican Energy serves the energy needs of more than 1.6 million customers in Iowa, Illinois, Nebraska and South Dakota. 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. And with the region's record-breaking wind resource in 2022, we delivered 100% of our Iowa customers’ annual electricity needs with renewable sources. Through our GreenAdvantage® program, our Iowa customers can 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 2022, 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 $5.75 billion. For more information on MidAmerican's renewable strategy, see slides 87-97 of Berkshire Hathaway Energy's 2023 Fixed-Income Investor Conference presentation
We are stronger and more successful when we work together. MidAmerican works collectively with the Berkshire Hathaway Energy family of businesses to support our broader sustainability goal to achieve net-zero greenhouse gas emissions. Reaching net zero in a manner our customers can afford, regulators will allow and technology advances support is key. This approach centers around making reductions now, delivering on commitments to increase renewables, investing in transmission infrastructure, and using proven technologies while continuing to explore innovative ways to allow the use of existing fossil resources in a more carbon friendly way.
$44.1 billion investment in renewable energy
Through December 31, 2022, Berkshire Hathaway Energy has spent more than $37 billion on renewable energy, and has plans to spend an additional $7 billion by 2025.
