Avoid gas stations altogether. Electricity is cheap and ubiquitous. EVs are the greenest vehicles you can buy. But limited range means mostly local driving.
Gas-electric hybrids are the most efficient cars that don’t have a plug. There are nearly 40 available models—ranging from compact to full-size SUV.
Diesel vehicles have exceptional fuel efficiency and are fun to drive. Today's diesels are much cleaner and quieter than those from previous generations.
Great fuel efficiency is possible with conventional gas engines. There's a growing list of reasonably priced models getting 35 mpg or higher.
Research is required to find a local station that pumps CNG (Compressed Natural Gas), and choice of models is limited. But the payoff is low-cost fuel that burns clean.
If you live near an E85 pump, a flex-fuel car utilizes a domestic source of farm-grown fuel.
