According to this notice from the city, we have door to door solicitors in Carbondale until the end of April. They represent Liberty Power, a energy aggregator competing with Homeland Energy, the city's current energy provider.. Liberty Power offers rates of .055 cents per kilowatt hour, compared to Homeland Energy's rate of .058. However, Homeland Energy offers 100% green energy while Liberty Power, it appears, does not. To me, paying .003 more per kilowat hour for renewable energy is certainly worthwhile. However, you do have the option of changing over to Liberty, all you have to do is sign the paperwork the solicitor offers.
