It's easy in many states to pay for a "renewable" energy plan. In practice this means that your energy still comes from the same sources, but your utility purchases renewable energy credits from other solar and wind providers elsewhere in the country and "retires" them. This adds a small amount per-kWh to your bill, but in practice it's still dirt cheap. The problem is that I don't know if the prices are high enough to incentivize providers to actually build out renewable energy sources, or if this just makes people feel good.
