Our generations are facing huge environmental disasters that are linked to excessive emissions of greenhouse gases into the atmosphere. Governments created a number of international initiatives trying to preserve the environment but without greater success. Transport sector is one of the leading polluters and in the near future we won’t be able to burn fossil fuels in order to create useful work due to ecological unsustainability of that kind of system. We will have to completely turn to alternative forms of producing (converting) energy. One kind of alternative energy used in vehicles is electric energy. It’s omnipresent in our day to day lives, but we rarely see it propelling vehicles. There are some other forms of ecological vehicles like the ones using alternative fuels that are less harmful or aren’t harmful at all, but transport sector made of electric vehicles is the only one that is seen as sustainable for long term use. Production of such vehicles began with the turn of the century, but we rarely see them even today because in the eyes of the public they are still an unproven new technology and are more expensive in comparison to the conventional vehicles.
