I just signed up for a program that will supply 500 kWh per month of wind power for our home. It feels GREAT to actually put my money where my mouth is when it comes to renewable energy!
I just discovered today (per a tip from a friend) that we're eligible to purchase the option of either 100% wind power, or purchase 100 kWh blocks of wind power per month. We used 1040 kWh in July 2009, thus we'll buy about 1/2 of that in wind power.
The catch - you have to stay with the program for at least a year. And it could cost a little more than what you are paying now (but not much). From our energy provider's site:
The cost of all the Windsource energy you purchase, whether you chose to purchase blocks or 100% Windsource, will be based on your actual metered electricity usage. For 2008, the average net Windsource charge was $0.70 per 100 kWh block. Based on this rate history, an average residential customer using 675 kWh per month and signing up for 100 percent Windsource should expect an average increase of less than $10 to their monthly bill.
Increase in my bill? Don't hang up yet! Here's an article from the Minneapolis Star Tribune - Wind Power was CHEAPER in July of 2008. Headline: Xcel wind power proved to be a July bargain
Start up time is about 1 month. I'll report the results as they come in.
