An “off-grid” home conjures images of a cottage in the middle of nowhere and a hair-shirted existence. But it’s possible to turn a normal property into a carbon-negative home – simply by using an electric car. Some tech-savvy, money-saving homeowners have turned their houses into energy-efficient “eco-systems”. These use solar panels to produce electricity, which is then stored in their electric car or a battery pack overnight. In some cases, electric vehicle owners are able to buy cheaper and greener energy overnight and sell it back to the grid at peak times, cutting their bills substantially. One couple, Shilpen Patel and his wife Reshma, recently installed a “vehicle-to-grid” system in the driveway of their north London home. This method allows electric vehicle owners to make money by selling power back to the grid when demand is high, while charging their batteries when supply is plentiful. The Patels’ Nissan Leaf has a battery large enough to power their home for two days.
