I looked at my bills. What changed is the city/clean power alliance (CPA) now provides my power, they claim to provide 100% clean power to my home. I now pay a generation charge and some other fees to the CPA. There are options to have 40%, 50%, or 100% clean power with 100% being the default. According to the CPA calculator, the difference in cost between 40% and 100% clean power is less than 10% of the bill - either way you still pay more now. Not complaining about having clean power.
