Electric cars

Electric cars are vehicles that use electric energy stored into batteries. The batteries should be recharged more often than the fuel in a normal car and had to be changed from 3 to 5 years. The EC has a zero emission ot polutants that produce smog effect and other Greenhouse gases. This makes them environmentally useful but still we have the polution produced while manufacturing the electricity. EC also reduces the oil market dependance, the noice and also gives evidence of about 90% efficiency. The moving energy can be converted into electricity again which reduces the energy requirement of a trip. Although being safe for the reason that there is no danger of explosion the electric car is good only for short distances. Except for that the batteries, thir instalation and recharging are too expensive fot a evarege salary of 100 $ in Bolcan coutries for example that cannot afford 50 000$ for full pacage of the service.
