Cheese curds, thunderstorms, and hospitality in Wisconsin

The annual Midwest Renewable Energy Association (MREA) Renewable Energy and Sustainable Living Fair was held this past weekend in central Wisconsin drawing people from all over the Midwest. Roughly 15,000 festival goers made the trip from Minnesota, Iowa, Illinois, Ohio, Kansas, Indiana, Michigan, and other nearby states. I even managed to meet a woman who journeyed 18 hours from Oklahoma to become better educated on eco-living tips and renewable energy knowledge.

Highlight of the fair: while taking a gander around the fairgrounds, I managed to run into David Johnson, a radiologist from Minnesota (pictured here) who was showing off his Chevy S10 electric pick-up that was fully equipped with a TerraPass sticker. He did a great job of plugging TerraPass as one of “the most cost-effective ways to contribute to climate change mitigation” to all those who visited his truck and his enthusiasm was truly contagious.

Thanks again to all those who stopped by the booth to learn about TerraPass and if you weren’t able to log on at the fair, use our online carbon calculator to get started.

    I tried to look up an electric Chevy S-10 pick up on the Terra Pass carbon calculator and they did not list it. I know they exist because I have friends that have them and I remember when they were being sold new by the factory. Is GM trying to pretend they never made them either, like they did the EV1. Tell me, which Terra Pass did he have on his S-10?

    PS: I have a friend who travels form Washington State evey year to go to your event and he has nothing but great things to say about it. Keep up the good work!

    I would recommend using an electricity carbon calulator for your state and enter in how many kWh you use in a year for the E-S10. You can then figure out which terrapass level is the equivalent for that many lb. of CO2. Try this one:

    I think “hybrid” is 6000 lb, “efficient” is 8000 lb and so on.

    You beat me to it. =)

    We typically don’t list electric vehicles in our calculation because there are no tailpipe emissions. The emissions come from the production of electricity which will vary in its emissions profile depending on where you live and what type of source (coal, renewable, etc.) it comes from.

    I believe David (featured in the picture above) used his own calculations to find the appropriate offset level.

    If you are interested, the e-grid database located at is also a great resource to start with.
