Our topic is electric cars. Companies are starting to make electric cars and we wanted to find out more about them. Also we were interested in cars and wanted to learn more about the new car technologies. Supposedly, electric cars are environmentally friendly and we wanted to see if this was true. In the near future we will be buying cars and were interested in what may be a new environmentally friendly car.

When we run out of oil on earth, the only energy source will be electric. But, we need to make sure we don't run out of oil because many things run on oil, like lawnmowers, boats, planes, snow blower, leaf blower, etc. So, making an electric motor will be necessary to help preserve oil. It's better to use electric now to save and preserve oil for later. Eventually, we will learn how electric works and maybe, use it more often.

You maybe wondering how much one of these cars cost? Well it is anywhere from 30,000 to 40,000 dollars. This may sound like a lot but it is a new technology. "Drivers may ultimately compare fuel efficiency through another measure: cost per mile. If gas costs $3 per gallon and typical mileage is 25 mpg, it will take 4 gallons of gas to go 100 miles, at a total cost of $12. The per-mile cost is one hundredth of that, or 12 cents per mile. For the Prius, at 50 mpg, fueling costs are half that: 6 cents per mile." (|jdbmihjnh||ssJN "U.S. News & World Report"||sljh','');|U.S. News & World Report; Apr2010, Vol. 147 Issue 4, p47-49, 3p) In the long run it saves you money. Per mile, it costs double to use just gas then an electric car.

Now you maybe asking yourself, how does this help the environment? These cars save you gas and money. Also these electric cars are more efficient then gas cars. China and America are the 2 top polluting countries in the world. By 2020 China wants at least 5 million of these electric cars in use, instead of gas.

It takes around 8 hours to charge the car battery. Researchers say to plug it in overnight so it is ready the next day. It plugs into a wall outlet. The outlet should be 120- 200 volts for a full charge. In a single charge, the car can go anywhere from 40- 100 miles, depending on the car.

The cars we use today use both battery and gas. The battery is a waste though, because it only powers the electrics in the car, not the car itself. In cars today you need to buy both gas and a new battery every few years. The electric cars use only electric. No gas is used to run it.
