Last month, we signed up for wind energy from our electricity company. We just paid our first bill with the wind energy charge, and it was pretty easy on the check book. We used 857 Kwh this month (as opposed to 1073 last year – yea! keeping the temp. higher and drying clothes on racks instead of the dryer is working!). The total windsource charge was $32.67. But then there’s a “windsource adjustment” that subtracts $18.78 from the bill (I assume this is a state refund type of thing, sort of like the tax break for buying a hybrid car). So the extra charge for using wind energy for all of our electricity came out to $13.89 for the month. That’s in July, which is a high energy month (even though we’ve been keeping our thermostat at about 78 degrees, the ac has still been running quite a bit, just to maintain that level). Most months of the year we don’t use more than 500 Kwh, so our average windsource expense is probably going to be under $10/month. And it’s money very well spent.
