Will Electric Cars Lower Global Warming Emissions ?

Increasing use of Electric cars would dramatically reduce emissions that cause global warming and air pollution. Therefore, increasing the use of Electric vehicles is important for all of us.

The current fleet of gasoline-powered cars and trucks leaves us dependent on oil, contributes to air pollution problems that threaten our health and produces large amounts of global warming pollution.

Some Electric Cars run on electricity alone, while others are paired with Gasoline engines to create Hybrid Cars. Hybrid Cars can get over 100 miles per gallon, while Electric Cars consume no gasoline at all. Electric Cars produce no direct tailpipe pollution when operating on electricity and there is enough Power infrastructure to fuel them. As renewable energy sources, like wind and solar, meet a larger share of our electricity needs, Electric cars will contribute to little or no air pollution.

The current electric system in the US  has the capacity to fuel up to 73 % of Vehicles without building another power plant by charging vehicles at night or using solar panels by day. However, the US  will need to clean up its electric grid to reap the full environmental potential benefits of Electric Cars.

Electric vehicles offer a way to utilize the natural resources and minimize Fossil fuel consumption.  Electric Vehicles  reduce mobile point source emissions and are one step toward energy independence. The technology needed to build workable Electric Cars exists today, and they have several advantages over  Fossil fuel Cars including the fact that they require less regular maintenance and no oil changes.

The Government of all nations in the world should harness the power of Electric Vehicles by setting clean Vehicle standards, offering financial incentives for buyers of Electric vehicles, creating a low-carbon fuel standard that allows Electric Vehicles to contribute to lowering global warming emissions & promoting renewable energy.

However, Skeptics say Switching to Electric vehicles will not have a significant impact on Carbon emissions.  As  most electricity in the world is still generated by burning gas and coal, the difference between an Electric car and a small, low-emission petrol or diesel car is negligible. Success depended on the availability of Green electricity.

A range of new low-carbon energy sources was needed to ensure a greener power supply to Electric cars. These included new nuclear power stations, wind farms and tidal barrages. A smart grid was also needed that could allow millions of vehicles to be recharged using low-carbon electricity without overwhelming local distribution circuits.

However, Electric vehicles are the future of transportation. Electric vehicles are green, quiet, and eliminate trips to the fuel station. Best of all, they are fun to drive.

How much voltage would i need to charge to charge the chevy volt or any car using an electric engine?

this is a science project, im trying to figure out how many volts or energy would it take to charge a car electric moter by a wind turbine. So that the car runs completely off the energy produced. also what size the car moter ,the battery ,and generator

The car battery is charged with power, as KW over a period of time, which is onergy as KWh. The motor is rated as power in KW, and uses power over time as energy in KWh. The power used by the motor varies however. Depends on how much acceleration, wind resistance and so on. It is minimal while cruising at a moderate speed, maximum when accelerating hard. You can assume it won't exceed the maximum power rating for more than a few seconds.

The battery has to provide enough KWh for running the motor over a desired period of time/distance. Often the figures for cars are quoted as distance run (range), but even so the energy used depends on the number of stops and starts and the speeds used.

The power to recharge depends on the efficiency of charging (chemical efficiency and the electrical efficiency of the charger). Allow something like 130% of the energy used to get the battery recharged.

The link below has some figures like range (all electric) 40 miles, battery 16KWh, and recharging takes 8 hours or 3h with bigger power supply. From this we can assume:

The average energy usage is 0.4KWh per mile or 2.5 miles per KWh. This is something like 4.8c per mile from the grid in the US.

It takes 21KWh to recharge, and that is over 8 hours, so the charge power is 3KW or less over a period of time totalling to 21KWh, taking at least 8 hours. A 3KW wind generator is likely about 18 to 20 feet diameter, not all that small. It will only generate this power in significant (I should say strong) winds. It is likely to produce about 1KW average over a period of time in a region that is "good for wind". It does nothing until the wind speed exceeds a threshold, then increases as the wind speed.

In reality these figures may be different because the battery may not be fully discharged ever (toi ensure its life is long). This may mean only 8KWh is ever used or replaced in the 16KWh battery.
