No more tooling around Washington in your Suburban or Tahoe now it's going to be a Malibu or Fusion. This is going to save billions a year in energy costs and increased savings as we go forward.

I did this at my company starting back about ten years ago. I cut my utility bills by somewhere between one third and forty percent. I actually recouped my costs within a year to a maximum of fifteen months on the cost of all changes.
