Managing Incentives for Green Vehicles

With increasing concerns about global warming, energy security,

and gas prices, policymakers have encouraged the adoption of

more efficient vehicles.These automobiles run the gamut from alternative

fuelsuch as hydrogen, natural gas, biodiesel, and electricto the

more prevalent (at least in the United States) hybrid-electric vehicles offered

by a growing number of manufacturers.Hybrids still run on gasoline but are

much more efficient than nonhybrid models of similar size and performance.
