Apart from combating pollution, electric cars in the EU could contribute significantly to stabilising the bloc's electric grids.
The popularity of electric vehicles (EVs) is growing rapidly and is poised to help foster much greener transport in Europe's near future. There may be yet another important added benefit emerging from widespread use of electric cars, namely their potential to help stabilise and balance demands on national electric grids using their electric storage capabilities. To illustrate, if only 5.5 % of Germany's car fleet becomes electric, the country will have enough storage capacities to provide all required stabilising power to the grid from EVs.
