You're absolutely right.
Here in Marin county, you can opt in to using renewable energy, which my wife and I have. The public renewable utility rate is significantly cheaper than the standard PG&E rate. However, I am forced to pay more than the actual cost that the public renewable utility charges, because -- due to California state law -- my electric bill comes from PG&E, who -- despite not making the electricity -- has responsibility to charge the consumer. Of course, PG&E charges a 'convenience and distribution' fee that eradicates the difference in pricing between the renewable resource and their own electricity. Note that, if I opt in to using PG&E generated electricity, they kindly 'waive' the fee. Thus, despite the renewables being cheaper, I do not get the benefit as the consumer.
I have contacted my state senator and representative, and they sent me back a form e-mail about how they are 'standing' up to PG&E. Give me a break.... this is something that is easily legislated.
