Smart grids and gradually rising generation will ensure the electricity supply for e-car growth.
Clearly, a growing electric vehicle (EV) fleet will increase the electricity demand on power systems. But the total energy and peak power needed will not pose a problem, thanks to the adoption of smart grids and progressively increasing electricity generation.
For example, studies show that a million additional EVs in Germany would consume just 0.5% of total demand and wouldn’t affect the country’s electricity grid. A UK analysis concluded that if one in three cars sold in 2035 is fully electric, the vehicles would make up only 3% of total electricity demand. Similarly, Norway, the global leader in e-car market share, demonstrates that there is no need to be concerned about the electricity supply.
Meeting power demand
Increase in demand will be met by the growth of renewable energy generation in combination with energy storage systems and smart grids. Owners will charge their cars when electricity is cheaper, for example when wind and solar energy are plentiful, or overnight when demand is typically low.
EVs could even provide a boost to the electricity grid by discharging energy to buildings or the grid to help cope with fluctuations from intermittent wind and solar farms.
