Green power, in its simple form, is defined as electricity that is generated by using renewable energy sources that have minimal impact upon the earth. Two of the more commonly known renewable energy sources are wind and solar. Their popularity is based on the fact that they are naturally produced, have low operational costs, and that they produce electricity without emissions.
In 2014, City Utilities added solar energy to its portfolio of locally-generated electricity, with a 4.95 megawatt solar farm. Customers can voluntarily choose to participate in this solar program and elect to have some or all of their electricity needs be provided by the energy produced at the CU Solar Farm.
Since 2009, City Utilities has been purchasing 50 megawatts of electricity from the Smoky Hills Wind Farm near Salina, Kansas. In 2016, City Utilities began receiving 200 megawatts of purchased wind energy from a wind farm in northern Oklahoma.
