I think that electric vehicles are really good for local environment, where there is a huge problem with air quality. They could for example reduce occurrence of smog and increasing standard of living for residents of large cities. However, I am not so convinced about replacement all traditional vehicles with electric ones (at least for now), due to the greater carbon footprint of production the electric vehicles and because of some methods of generating electricity, which powers their motors (eg. from fossil fuel, like coal). There is also a big problem with disposal batteries. I think we should be really careful to not solve the problem of air pollution at the price of other part of our environment. I hope someday we will be able to have a good solution for these issues. It is a pity that we cannot use safely the burning of hydrogen to get an energy. Deviating from the topic of environment, there are also issues with a longer time of refuel electric car and their smaller range (compared to traditional motors). However, I think those problems are easier to solve, as they are in the interest of companies producing electrical cars and wanting to sell them as many as possible. In the end I hope someday there will be vehicles that could be practical and eco-friendly simultaneously. I will be grateful for any advice, corrections, suggestions, anything that will help me improve my writing skills :)
