How good are electric cars compared to normal ones? How do they work exactly?

I'm 17, I'll get a car soon, I'm just wondering how electric cars stack up next to a regular car...pros and cons?

Answer
Electric cars come in hybrid and pure-electric forms. Hybrids use gas engines in combination with electric motors, and may or may not have to be plugged in. Pure electric cars need to be plugged in, and the time it takes varies.

This explains the variation in charge times: http://www.plug-in.com/charge-times-how-long-to-fill-your-battery/

If you only plan on driving your car short distances between recharges, then an electric car will save you money in the long-run. However, since you're young and might want to take road trips or travel to college, you might want to wait until prices for electric cars go down.

Performance-wise, they can be pretty equal if you are willing to pay the right price. The available options are less, however, and you should put a little time into researching a car before you buy it. I'm sure you already know to be safe once you get your car. Congrats and Good luck!

How would the environment change if everyone drove electric cars?

Just having fun speculating and such, how much better would the environment get if the world drove electric cars.. would we physically see a noticeable change?.... I mean, this is obviously not possible in the near future, the whole word driving and being comfortable with electric cars won't be reached at least for another 50-100 years, but just to satisfy my curiosity.. how much will this benefit our planet?

Answer
How would you describe the change? It would be hard to fix an actual percentage. You might listen to the inspirational beginning of an EV world podcast: http://www.evworld.com/evworld_audio/gpastor_shanghai-to-paris1.mp3 You could read a nonfiction book on the subject: http://www.amazon.com/Future-Drive-Electric-Sustainable-Transportation/dp/155963328X or you might see a movie that featured electric cars or watch a youtube video interview:

But if you wanted to fix a percentage it would have to start with the pollution given out by the vehicles of today. How much does auto pollution presently damage our planet? You would have to look at each element of pollution separately. Also, are we counting all harmful substances or only those that will be metabolized in a fixed or variable amount of time? How do we determine how much time.

We can say with some certainty that approximately 60 to 70% of crude oil's refined products are used in transportation. The pollution will be found in the air, our water and our soils. Oil pollutes during its production1, exploration (the BP well was an exploratory well), transportation (tanker spills), refining (energy usage and byproducts, transportation and storage again (road and pipeline spills ) pumping (ground and water contamination at gas stations, and use (air pollution, water and soil pollution from "lost" oil 2) Of this we can probably attributed 50% to ground transportation that would be replaced by electric cars and trucks. (I would assume you may include trucks in you overall assessment.) This source determines the tonage per vehicle of greenhouse gas emissions: There are over 200 million vehicles on the roads in the US alone producing 1 billion tons of CO2. Refineries would add to this amount.
