At the risk of stating the obvious, if it's only added $2-3 to your bill, then it's only given the energy company $2-3 to build renewable capacity. That's not nearly enough to make any kind of meaningful impact in your carbon footprint (assuming you have somewhat average consumption).

I spend about $20-30/month on electricity, so it's about a 10% change. My electrical consumption is about as low as I think one can get it without going without things like refrigerators.
