What are the Environmental effects for a hybrid car?
As with all alternative energy, there will always be consequences to using resources. Obviously raw materials and machines are being used to produce these cars, possibly using fossil fuels for energy at the plants. While more relative to the car, there is a difference between a hybrid and electric car. If you're talking about hybrid, gasoline is used to start and stop the engine. Once the engine is at a certain speed, the electric motor will take over. In a parallel hybrid, the car is driven by gasoline and power is maximized by the batteries. Either way, toxins and cloroflourocarbons (CFC's) are being produced and released into the atmosphere. Flexfuel cars and biofuel cars can run on ethanol or even vegetable oil which don't produce harmful gases such as cars using gasoline. The alternative would be an electiric car, but while you're charging it, you must remember that the electricity must still be produced at a plant somewhere, which may or may not be using fossil fuels to produce their energy.
