I voted some. A bit of hydro and a bit of wind but mostly coal. My electric company offers a Greenpower program where I can voluntarily choose to pay an extra $2.50 per month per 100KWh block. However, I can't figure out what it is supposed to accomplish. Water is going to continually fall over the dam and the wind will pretty much blow whenever it wants to. Since the infrastructure is already built and it takes a very long lead time to replace, coal has to provide the remainder. It should have some effect on the power company's bottom line, so I guess it does have the benefit of reducing or delaying rate increases for non green power customers. If I had a choice of electricity suppliers, I would definitely be tempted to go with a green producer.
