Interest in it has resurfaced due to concern for the environment and the damage inflicted on it by gasoline cars, but although electric cars are once again on the market, a mass transition to such vehicles from their gas-powered equivalents seems unlikely to happen just yet. One of the main issues is that the purchase price of an electric car is still by far more expensive than that of a gasoline car. Electric car engines are pricier to develop, produce and operate in comparison to internal combustion engines, and many customers simply are not prepared to spend more money for a vehicle just to reduce their carbon footprints. The range of electric cars is also a problem. Battery charges are limited, and so is the infrastructure available for recharging them. Battery life is also an issue, the fact of the matter being that electric batteries deteriorate over time and eventually have to be replaced.
