Green Energy customers are typically making the decision to offset the carbon impact of their energy usage to some degree. KU and LG&E want your level of purchase to reflect any level of impact that you choose. Therefore our Green Energy Calculator will show you the environmental benefit of your purchase in terms of carbon emissions reduced, at any level you choose.

Another way to make this decision is to call KU or LG&E customer service and inquire about the "average monthly kilowatt hours (kWh) of electricity" you use. If you use an average of 900 kWh of energy each month, and you want to fully offset the carbon impact of your usage, you would enroll in Green Energy for $15 per month.^*
