L.A.D.W.P.'s Green Energy Program

I just signed for L.A.D.W.P.'s Green Power program. Again, seems like so little (an extra $3/month) to support L. A.'s green efforts. I found it here on their website. I needed my DWP bill in order to enter my account number, but filling out a simple form online was all it took. I liked how you could choose the percentage of energy you wanted as green energy. I've heard from others in my workshop that previously, you only had the option to purchase 20% green energy. Now you can choose from 20-100% depending on how much you wanted to support.
Makes me proud of our smog torn city.

here's an explanation form the form I filled out...

The price for new green power is slightly higher than power generated from conventional sources such as coal and natural gas. The extra cost is currently 3 cents per kilowatt hour, which is applied only to that portion of renewable energy that is chosen. The minimum contribution percentage for residential or small non-residential customers is 20%, but up to 100% may be elected. For the average LADWP customer that chooses a 20% contribution and whose monthly electric charge is $50, the additional charge would be $3 (or $6 on a bi-monthly bill). This extra cost may be offset by free energy efficiency products and services provided by LADWP. Participating customers are required to remain on the Green Power rate for a period of no less than 12 months.
