Forbes magazine describes a form of alternative energy that is already here. Wasted heat from large factories is beginning to be captured and used to produce electricity. It is happening right now in the upper Kanawha Valley at West Virginia Alloys. Here is the Forbes article.
The article notes that utilities and public service commissions often stand in the way of this new generating method, perfect for a distributed grid system.
“Working against electricity production from waste heat is the fact that most states still have utility-friendly laws that prohibit nonutilities from selling power directly to others without going through the grid. Bilateral agreements to buy and sell power can be done across the grid, but producers such as RED must surrender roughly a third of the selling price to a utility for transmission fees, even if it’s just across the street.”
