As we transition to a cleaner energy future, our businesses continue to deploy noncarbon generation, explore advanced technologies such as carbon capture, retire coal units in phases throughout our regulatory jurisdictions, advance transmission infrastructure to more effectively develop and integrate noncarbon resources, and leverage those efforts with the deployment of energy storage. In alignment with the Green Bond Principles published by the International Capital Markets Association and the Loan Market Association Green Loan Principles, Berkshire Hathaway Energy and its U.S. subsidiaries may issue bonds, loans, commercial paper or other financial instruments to finance or refinance projects with intended environmental benefits that are in-line with our Green Financing Framework.
We support our sustainability efforts by aligning our financing strategy with our focus on minimizing the impacts of our operations on the environment. Our pioneering commitment to renewable energy began in the early 1980s with preparations to develop our first geothermal project in Southern California. Today, our businesses are No. 1 among investor-owned utilities with clean power in operation in the U.S. Some of the results of these efforts are outlined in our businesses’ green financing impact reports.
Invested in clean power at year-end 2022.
