Can electric cars save the environment?

Then there are also hybrid cars that use both fuel and a battery charged electrically. I think i would prefer these. i have just searched for it and the environmental issues are as follows: The hybrid vehicle typically achieves greater fuel economy and lower emissions than conventional internal combustion engine vehicles (ICEVs), resulting in fewer emissions being generated. These savings are primarily achieved by three elements of a typical hybrid design: relying on both the engine and the electric motors for peak power needs resulting in a smaller engine sized more for average usage rather than peak power usage. having significant battery storage capacity to store and reuse recaptured energy, especially in stop-and-go traffic. recapturing significant amounts of energy normally wasted during braking etc. (regenerative braking) This is a mechanism that reduces vehicle speed by converting some of its kinetic energy into another useful form of energy, dependent upon the power rating of the motor/generator; other techniques that are not necessarily 'hybrid' features, but that are frequently found fuel saving measures on hybrid vehicles include: shutting down the engine during traffic stops or while coasting or other idle periods; improving aerodynamics ; (part of the reason that SUVs get such bad fuel economy is the drag on the car. A box shaped car or truck has to exert more force to move through the air causing more stress on the engine making it work harder). Improving the shape and aerodynamics of a car is a good way to help better the fuel economy and also improve handling at the same time. using low rolling resistance tires ; (tires were often made to give a quiet, smooth ride, high grip etc. but efficiency was a lower priority. Tires cause mechanical drag, once again making the engine work harder, consuming more fuel. Hybrid cars may use special tires that are more inflated than regular tires and stiffer or by choice of carcase structure and rubber compound have lower rolling resistance while retaining acceptable grip, and so improving fuel economy whatever the power source. These features make a hybrid vehicle particularly efficient for city traffic where there are frequent stops, coasting and idling periods. In addition noise emissions are reduced, particularly at idling and low operating speeds,[35] in comparison to conventional engine vehicles. For continuous high speed highway use these features are much less useful in reducing emissions.
