If you have<\/span> solar panels on your roof, it makes sense to add batteries, too, so you have some degree of self-sufficiency should you lose power. In fact, it might be a good idea to have such a storage system even if you don\u2019t generate your own power. That way, you can charge the batteries when power is cheap and use that stored energy when electricity is eye-wateringly expensive and the mercury is reaching for the sky like it\u2019s at a midsummer rave party and the bass just dropped.<\/p>\n

From a distributed power strategy point of view, it would make a lot of sense for everyone to have their own local power storage. But it\u2019s unlikely that folks who don\u2019t have solar, wind or, in some cases, hydroelectric power on their property will spend on huge and expensive powerwalls.<\/p>\n

However, there\u2019s an unlikely solution for this: The enormous battery packs people already have in their electric vehicles, and the California Senate is discussing a bill that is hoping to cut through the red tape associated with V2G (vehicle-to-grid) charging.<\/p>\n
