There is a Department of Energy-sponsored project right now to test how plug-in hybrid vehicles affect the grid. A number of utilities, including Detroit-based DTE Energy are testing these vehicles right now, including this Saturn Vue which was converted to a plug-in hybrid. In its tests with a plug-in hybrid Escape, DTE Energy has put over 13,000 miles on the SUV and gotten 68 miles per gallon, according to DTE CEO Anthony Earley.
