2) Effect of hybrid cars on environment? Hybrids have fossil fuel engines that work alternatively or in concert with electric motors to reduce smog emissions and increase fuel economy, without ever having to be plugged in. As gas pump prices inflate and as foreign oil increasingly becomes a non-reliable source for American consumers, sales and visibility of hybrid cars are rising. The hybrid vehicle does not have to be plugged in like electric cars. The batteries, much like a conventional battery recharges itself. The electric battery is the only power source when the car operates on low speeds, when more power is required, the gas engine kicks in. The electric engine releases no emissions. |
