energy efficiency

The U.S. EPA estimates that companies in Michigan waste up to a third of the energy they buy because of inefficient buildings and equipment.

But most of the companies just keep paying those high energy bills, month after month, because they can't make a business case for a big energy efficiency project. The payback for the upgrades takes too long – often ten or more years.

Living off the grid can be a lot of work, but Joe and Shelly Trumpey and their two daughters have managed it for years. Their home is near Grass Lake in Jackson County. Finished in 2009, the home relies on straw bale insulation, solar power year-round, wood burning in the winter and efficient construction to keep it running.
