Nearly 204,000 hybrid electric, ethanol-capable E-85 and
clean-diesel autos were on Colorado's roads last year,
according to R.L. Polk and Co. figures. That ranks Colorado 18th in the nation in terms of the total number of alternatives in use.
Nationally, 1.5 million alternative fuel vehicles were sold in 2006, surpassing automakers' expectations by 50 percent.
Last year's sales brings the total number to 10.5 million alternative-fuel vehicles on the road.
April has been dubbed Alternative Fuel Autos Month, and there are 60 models of alternative-fuel vehicles on the market. That's up from just 12 models for sale in 2000. A complete list is at www.DiscoverAlternatives.com.
