It's a fact that electric vehicles are going to impact the way we consume electricity and shape how the utilities companies will evolve.

However, there is also a second not so known "by-product" of the electric vehicles that will result in a win-win  situation for customers and generators. 

The V2G (Vehicle-to-Grid) technologies enable customers to store home generated renewable energy in their battery, or fill their battery when energy tariffs are low or even free. Customers can then draw energy out to power their home or to the grid (and get paid for it!) when it is needed or tariffs are high. 

On the other hand, for the utilities companies this tech would play an important part in helping to balance the electricity network as part of their demand side response (DSR) initiatives.
