Are Electric Cars the Future?

Electric cars have become much more common over the last ten years. They produce no exhaust fumes, which helps to keep city air cleaner. They are also cheaper to run because electricity usually costs less than petrol. However, they are still more expensive to buy than many ordinary cars. Another concern is how far they can travel on a single charge. In some areas, there are still not enough places to charge them. Building the batteries also requires a lot of energy and raw materials. Despite these challenges, many governments plan to stop selling new petrol cars. It seems likely that the roads of the future will be much quieter.
