FAQ - tzero and other AC Propulsion EVs:
"Why build electric vehicles?
Because people will buy them. They are smooth, quiet, powerful, efficient, clean, convenient, and fun to drive. There is also air quality. Compared to the cleanest gasoline cars, such as hybrids and PZEVS, electric cars reduce emissions of hydrocarbons, carbon monoxide, and nitric oxide, even considering the emissions from powerplants.
Perhaps the best reason is energy security. Everyone from the President on down agrees we import too much oil and that it comes increasingly from unstable regions of the world. We have to shift our energy use away from oil. Electricity comes from natural gas, coal, hydro, solar, wind, geothermal, and nuclear, but very little electricity comes from oil. Electricity is energy without oil. Electric vehicles are transportation without oil.
Some think hydrogen is the ultimate fuel, but hydrogen is made using electricity. It is more efficient, economical, and convenient to use the electricity directly to charge electric cars"
OK, maybe a bit overblown, but the main point is true...we can make electricity without oil, and that's why electric is the wave of the future.
