Would you like to have a fuel-efficient car as powerful as a regular gasoline car? Then start using electric cars. These cars don’t have moving parts. An electric car is powered by an electric motor which is fueled by electricity.

How Electric Motors Work

The electric motor gets its power from a controller, which gets its power from batteries. The accelerator pedal connects to a potentiometer, which sends a signal to the controller to tell it how much power it has to send.

Electric Cars on the Market

The Tesla Model S is an all-electric sports car. It costs around $90,000, but don’t worry about the price. Refilling a car with electricity is much cheaper than refilling with gas. For example, if 1 gallon of gasoline costs 3.5 dollars and 1 KWH of electricity costs 12 cents, you would pay about 20.58 cents per mile for a Mercedes S Class (@17 mpg), and you would pay about 5.3 cents per mile for a Tesla Model S (using a standard 110 volt outlet). This drops further to 4c/mi if you use a 220V outlet. Tesla Motors said that the range for the Model S was 306 miles for an 85 kWh Lithium-ion battery pack in the car.

The Nissan Leaf is a small electric car. The fuel economy is 126 MPG for a city and 101 MPG for highways. Nissan Leaf prices at $28,980 to $35,020.

Cons: These electric cars may be very fuel efficient and better for the environment, but they cannot last long on one charge. Also there aren’t many electric car outlets, and it takes 8 hours to fully charge a Tesla Model S using a 110-volt outlet.

Electric cars can prevent pollution, and are very fuel efficient which will lead to inexpensive fueling costs. A car with such positives is one that catches my eye! What about you?
