Kaiser Permanente signed agreements to purchase 223 megawatts of solar and wind energy in California, reducing greenhouse gas emissions from electricity use by 30% between 2008-2017. This includes 110 megawatts of solar and 43 megawatts of wind through offsite power purchase agreements, and 70 megawatts of onsite solar across hospitals by the end of 2016.
