Electric vehicle owners could earn thousands by supporting power grid
Electric cars could make their owners money while they sit idle Maskot Bildbyrå At least 90 per cent of the electricity generation being built today is renewable. But solar and wind farms produce electricity only when the sun is shining and the wind is blowing, so the power supply will fluctuate more. A pilot project in the US state of Delaware has shown that owners of electric vehicles (EVs) could make thousands of dollars each year by allowing their parked cars to serve as part of a giant collective battery that stores electricity when there is high supply and distributes it when there is high demand. Some data suggests that the average EV is driving as little as 5 per cent of the time. Otherwise, it is often parked and plugged into the grid. This means that, rather than building giant battery farms, electric companies could balance the grid by drawing power from these cars when usage peaks in the morning and evening, then recharging them during the day, says Willett Kempton at the University …
