Harnessing the power of wind for a cleaner Colorado.
Windsource® from Xcel Energy® is now open to new subscribers in Colorado. When you purchase Windsource you are helping to support clean, renewable wind energy generated from Colorado wind farms. It’s an affordable and easy way to help Colorado’s environment.
With Windsource, you choose how much wind energy you would like to support. You can choose a fixed number of Windsource blocks (100 kWh each) or choose the 100% Windsource option. Windsource is available on a first-come, first-served basis. Once our wind energy supply is fully subscribed you may be added to a waiting list.
