This is not the point. The DOD has set a mandate to reduce its consumption of raw materials including fossil fuels. We also are to reduce water and power consumption by like 2014. We lease hybrids which cost more than a smaller suv, were supposed to put e85 in flex vehicles, which i have done. I paid the same amt for it as e10 but get 30% MPG.
The crazy thing is much of it is a pr stunt. My office is at a Dam, we have our own weir and mini generator that turns power for just the dam and our office. There is no storage capacity nor is it hooked to the grid to sell back power like the 7 large generators are in the dam. Its strickly for our power use at the offices. Now that thing runs X gallons an hour regardless of the actual power needs at that moment in time. Yet we just last year put in like 400 CFLs to reduce power consumption!! Thats great but there is no difference as that water will run through the dam anyway weather it makes power for cfls or incandesants its purely a PR and image thing, cause we cant store the saved power that we dont use under this system.
Now for maintence we have to swap to the grid and pay, this is where the savings would come but we dont do this often as it costs thousands of $'s per month to be on the grid.
Ick!
