<prompt> Human: I live in OH and use Duke Energy. A few months ago, I was sent a mailer to sign up for electricity sourced through 100 renewable energy sources on my bill with a company called CleanChoice Energy I accepted their offer and it seems that my energy costs have raised 20-30 each bill. Here is a breakdown from two past bills:Bill 1 415 kWH used------Distribution-Customer Chg 6.00Distribution-Energy Chg 415 kWh 0.02534200 10.52Delivery Riders 13.41Total Delivery Charges 23.93Generation Riders 0.12Rider RC 4.38Rider RE 21.67Rider AERR 0.22Rider SCR 0.03crTotal Generation Charges 26.24Total Current Electric Charges 56.29Bill 2 228 kWh used------Distribution-Customer Chg 6.00Distribution-Energy Chg 228 kWh 0.02534200 5.78Delivery Riders 10.98Total Delivery Charges 16.76Generation Riders 0.17Total Current Electric Charges 22.93Generation Transmission 228 KWH 0.12000 27.36Total Electric Supplier Charges 27.36Total Bill 50.29Despite using half the electricity, my bill stayed the same amount with CleanChoice added. For context, I live on the top floor of a three-story multi-family with around 1100 sq ft.I am interested in supporting clean energy sources, but Id like to know if this is the best method. Ive read in a few places that its not possible to send a different sources of energy to houses that are grouped together, which sounds like Im paying a premium for nothing? Others have said that theres no guarantee in knowing if the energy is sourced from renewable sources at all.Does anyone else opt to add this to their monthly electric bill? Is CleanChoice Energy a scam or a good value if Im looking to support renewable energy in the area?  <response>: The specific energy you use may not come from renewable sources, as it doesnt really work that way outside of having something like solar panels on your roof, but you are basically supporting a company that is installing more renewable sources to the grid, theoretically reducing the amount of non renewable sources that are needed.also, the reason your bill doesnt change much is because most of your bill is not really tied to how much energy you personally consume. a large part of your bill is basically a connection charge, money spent so that the utility can maintain reliable service to your house.
