I signed up for Rocky Mountain Power’s Blue Sky program a few years ago. Each year they send me these updates about my participation in the program. This year I received the following:
We are pleased to present your personalized 2008 Blue Sky support details to show you the difference you’ve made:
- Your current purchase of 2 blocks per month
- Your total 2008 Blue Sky purchase of 2,400 Kilowatt-hours helped avoid the release of 2,908 pounds of carbon dioxide emissions into the air,
- Providing environmental benefits equivalent to not driving 2,949 miles.
I think the 2 blocks of wind power cost about $3.90 per month extra. Not releasing 2,900 pounds of carbon dioxide into the air is worth far more than this! To join this great program, go to the Blue Sky Program website and sign up.
