    NOTE - AVISHEK'S ANSWER IS CRIBBED FROM ONE OF MY PAST RESPONSES. You can tell from the asterisks, which are my calling card.

    *

    The principal disadvantages are limited driving range and higher purchase price.

    *

    Offsetting the higher purchase price, however, is a lower operating cost - a typical EV driver will save $150 per month or more by using electricity instead of gasoline. If this savings is considered, and the shorter driving range works with your driving needs, the EV will probably have a lower overall cost of operation.

    *

    Advantages of EVs are - extremely low fueling cost - extremely reliable motor (electric motors have just one moving part - no maintenance required at all) - extremely quiet and smooth ride (no gear shifts needed at all) - no pollution generated (and very little generated from most power plants.)

    *

    Be aware that many other points cited as disadvantages are outdated.

    *

    Older battery technologies required frequent replacement, for example, but modern battery technologies are very robust. Chevy Volt's batteries are warranted for 100,000 miles, and are expected to last more than 150,000 miles. Even at that point, a total battery replacement is unlikely - Volt's battery is modular, and any of 200 cells can be replaced individually.

    *

    And modern EVs are equivalent in power to gas vehicles - both Volt and Nissan Leaf accelerate better than average cars, and have top speeds near or over 100 mph.

    Pros and cons depend upon the setting and the comparison. We could compare the EV to walking, a bicycle, in winter driving or at racetrack but the likely assumption in a single vehicle family setting and with a petrol vehicle. You also need to define what you consider to be an "Electric car?" Is a Volt which drives with electric and gas engines an EV? Is a Prius or other hybrid? I will limit my comments to battery electric vehicles.

    But already we have a problem because most battery EV advocates want to compare the EV to a two car household as a commuter vehicle with the argument that using the tool for the right purpose shows is most favorable to the EV and comparisons that don't fit the purpose are just a little silly. (pros and cons of a jack hammer for putting together a picture frame?)

    Within the appropriate setting there are 4 other considerations: The vehicle's: economics, environmental impact, strategic hedge, and its social appeal.

    ++ Economics -----

    - The EV will have less drive train maintenance. The petrol vehicle can have over 800 moving parts compared to as little as 5 for an EV.

    - The cost to fuel can be about 1/3 or less as the EV is 5 times more efficient and electricity is generally cheaper.

    - Batteries are expensive and fro 1/3 to 1/2 the price of the vehicle. The vehicles are more expensive than petrol counterparts for now. But as battery prices come down the balance of the vehicle cost is less expensive and presently is encouraging lots of innovation.

    ++ Environmental impact -----

    - The EV is a zero emissions vehicle. Overall the system within which it operates is about 2/3 to 1/2 less polluting than the petrol counterpart.

    - The EV does not use oil for lubrication and pollution from improperly discarded oil is also eliminated.

    - Batteries like present varieties will be even more likely to be recycled as they have value as stationary batteries when not suitable for an EV.

    - Range limitations encourage light innovative construction and safety features.

    ++ Strategic Hedge -----

    - on the individual level the threat of no gas at the pump is avoided

    - on a national level the potential exists to eliminate our negative balance of payments. Oil is mostly a foreign resource while electricity is domestic.

    - Anyone serious about the budget gap should be serious about EV adoption.

    ++ Social Appeal -----

    - The EV range fits into over 90% of most commuting patterns however some find range the greatest limitation. Planning a trip with an EV is relatively easy but lack of infrastructure makes many unplanned trips more problematic. IE it makes a better commuter vehicle.

    - Charging can be the great advantage of avoiding the pumps and fueling at home or the big disadvantage for an apartment dweller.

    - High torque makes driving an EV a lot of fun but can wear down the battery more quickly. Hypermiling will increase the vehicle range.

    Disadvantages - At the moment they are more expensive to buy, less powerful than the internal combustion engine so generally slow unless you buy a very expensive one (Tesla Roadster), batteries must be replaced every few years which is expensive, there aren't many places to recharge them at the moment, charges take a few hours so imagine waiting in a petrol station for a few hours, ranges are pretty short for long journeys.

    Advantages - They have the potential to be fast and develop longer ranges (see Tesla Roaster videos on youtube), they will become cheaper in the future, we will always have electricity unlike fossil fuels, we may one day have fuel cells where you will just replace a small box which contains the whole supply with a charged one.

    I wouldn't buy one at the minute unless I won the lottery or something, give them a couple of decades and I'm sure they will be much more advanced and the norm for people to drive.

    Some advantages;

    --------------------------

    *

    -Lower fuel cost. Electricity costs just 2 to 4 cents per mile. Gasoline cost is 12 to 30 cents per mile (depending in your car's mileage.)

    *

    -Higher reliability. Electric motors have just one moving part and require no regular maintenance. Think about the electric motor in your refrigerator, how it just runs and runs for decades. Would you want a gas engine in there?

    *

    -Higher efficiencies. EV motors are better than 90% efficient, generate no waste heat, and can even recover braking energy to recharge batteries. If we take the huge amounts of energy we use to refine gasoline, and use it to power EVs instead, our net energy usage will drop significantly.

    *

    -Energy independence. All the energy needed to power electric cars is made right here. No more imported oil, no need for foreign entanglements or wars protecting petroleum sources. Who needs the middle east anymore?

    *

    -Cleanliness. This follows from higher efficiency, and also from the energy saved (with its pollution) by refining less gasoline. Higher efficiency means less miles driven on a given amount of energy - which also means less pollution, no matter what gets burned to make the electricity.

    Some disadvantages:

    ------------------------------

    *

    -Driving range. Most EVs are limited to less than 100 miles per charge. Lower battery prices, and fast charging (a full charge in 5 to 10 minutes) will eventually fix this, but will take another 10 years or so.

    *

    -High purchase prices. This is common with any new technology, but prices are already starting to drop. The newest EV on the market, the Mitsubishi MiEV, is less expensive than its predecessors.

    *

    -Battery charging time. Some people like the idea that their car can charge overnight at home. Others see this as a disadvantage, since most EV charging takes hours to complete. Luckily, fast-charging is already feasible for some electric cars, and will become more common in the next decade.

    Advantages: No gasoline required, environmentally friendly.

    Disadvantages: Short range, long recharge times, expensive batteries.

    Save money not buying gas. Not supporting the oil companies a lot less, since they finally cannot supress alternatives like this. Helping the environment, but not as much as you think.

    Batteries pollute in landfills. Uses coal, nuclear, and wind turbines as energy source, which aren't as bad as oil, but also have their negative impacts on society too. No quick recharge stations yet so you can't go far compared to gas. Not much power either, gutless in comparison. Batteries are the weak point. Expensive to replace

    Overall better than hybrids but far from practical

    There are lots of different electric cars ...

    Can you give us an idea of what you're trying to compare?

    Hydrogen -> electricity -> motor

    Battery -> electricity -> motor

    Hybrids?

    There are all kinds of possibilities. What are you comparing TO?
