Environmental heroes Ed Begley Jr. and his wife Rachelle Carson will be appearing on the Oprah Winfrey show tomorrow, April 29.

Oprah will be interviewing Rachelle in studio while Ed gives a tour of their home via Skype. According to Wikipedia, the Begley home is 1,585 square feet and utilizes solar power, wind power via a PacWind vertical-axis wind turbine; an air conditioning unit cooled by Greenway Design Group, LLC.; an electricity generating bicycle used to toast bread, and he pays around $300 a year in electric bills.

The couple currently have a reality show about green living called Living With Ed on Planet Green.
