These days the industry tends to become more 'green' in order to save our planet from pollution. One of the inventions that will probably change the world greatly is an elecric car.
The first elecric car appered in 1884. It was invented by Thomas Parker, English engineer, known as "the Edison of Europe". These vehicles use energy stored in rechargeable batteries. Since then, they has become popular although it is still quite rare to see elecric cars in the streets in most countries.
Nowadays in Japan there are more filling stations for eletric vehicles than for cars working on fuel.It means that the era of electric vehicles is coming.A lot of companies such as Mercedes-Benz, Toyota, Nissan, Chevrolet and Volkswagen has already introduced this type of cars.
To sum up, this is the innovation of the future that will affect our lives a lot.
