Many new luxury homes in San Francisco now feature electric car charging stations. Helena Zaludova’s listing at 1864 Greenwich is just one example. This 5 bedroom, 5.5 bath home by M-PROJECTS will be returning to the market after Labor Day. For home owners who really want a zero carbon footprint, Tesla recently released the Powerwall Home Battery, using electricity generated through solar panels. The batteries can store 7 or 10 kilowatt hours of electricity and cost $3000 or $3500, respectively, for later use. I am looking forward to seeing these Powerwalls in my future listings.
