Alt Fuels Save the Day

Until they don't:

The federal government has invested billions of dollars over the past 16 years, building a fleet of 112,000 alternative-fuel vehicles to serve as a model for a national movement away from fossil fuels.

Under a mandate from Congress, federal agencies have gradually increased their fleets of alternative-fuel vehicles, a majority of them "flex-fuel," capable of running on either gasoline or ethanol-based E85 fuel. But many of the vehicles were sent to locations hundreds of miles from any alternative fueling sites, the analysis shows.

As a result, more than 92 percent of the fuel used in the government's alternative-fuel fleet continues to be standard gasoline. A 2005 law -- meant to align the vehicles with alternative-fuel stations -- now requires agencies to seek waivers when a vehicle is more than five miles or 15 minutes from an ethanol pump.

The latest generations of alternative vehicles have compounded the problem. Often, the vehicles come only with larger engines than the ones they replaced in the fleet. Consequently, the federal program -- known as EPAct -- has sometimes increased gasoline consumption and emission rates, the opposite of what was intended.

Read it all and keep it in your pocket for the next time you hear a politiciam promising to fix things. Thanks big government!
