I had posted this in February of last year, but it bears repeating. Here are the details:
My electricity provider, 4Change Energy, is offering a $25 credit after your second bill, when you sign up with the following link:
They offer low fixed-rate plans, starting at 6.9 cents per kWh with only a 3-month contract, and part of every payment goes to charity in a category you choose! My personal choice was American Cancer Society.
It costs nothing to sign up, and I've been very happy with the savings and the service so far.
