Electric cars came on the scene a few years ago as a green alternative to gasoline powered cars. Electric cars get their energy from a controller, the amount of power it puts out is controlled by how much pressure the driver puts on the accelerator. Electric cars are also know as Electric Vehicles or EV's for short. An electric car's energy is stored in a rechargeable battery which you can charge with your household electricity. There are all different types of batteries available. As with most things you get what you pay for, the cheapest batteries store the least amount of energy and will need to be charged often.
When it comes to EV's versus gasoline vehicles, there are five major differences. The first is that EV's don't produce the tailpipe emissions that gasoline vehicles do. Secondly, gasoline powered cars rely on OPEC for their supply of energy and electric cars rely on a utility company. Mileage is also a major difference, gasoline powered cars get about 300+ miles per full tank where as electric cars only get about 100 per fully charged battery. Another issue that some view as inconvenient is the time it takes to recharge an EV's battery. You can fill up your gasoline powered car in a few minutes, however an electric car can take hours to recharge. The final major difference is cost per mile, EV's only cost about two cents per mile and gasoline cars cost about 12 cents per mile.
Electric cars are a good choice for a number of reasons, including reducing harmful emissions, reducing our dependency on oil and they are overall cheaper to operate. EV's haven't been widely accepted yet mainly due to the need to be recharged, long recharging times and limited availability. However this will hopefully be changing soon as scientists and engineers are working to increase energy storage for batteries and reduce costs. Here are some pics of upcoming electric cars.
