Reduce your carbon footprint and your energy use



Inspired by the Al Gore documentary “An Inconvenient Truth”, Indradeep Ghosh and his wife Anita were determined to reduce the carbon footprint of their 1997 home. They decided on a complete retrofit of their house, replacing every gas appliance with all-electric ones, installing solar panels on the roof and purchasing fully electric vehicles.

“The water and space heating works perfectly. The induction cooktop is super-fast and a breeze to clean. The EVs are a joy to drive. And now, with my solar panels providing all my electricity during the day supplemented with SVCE’s 100% carbon-free energy during the night, I have successfully achieved a zero carbon footprint in all my energy use.

I have hosted several open houses to demonstrate to neighbors and the community how essential and affordable going all-electric is. In fact, the retrofit project actually spawned a graduate level course in Electrical Engineering at Santa Clara University Introduction to the Smart Grid that I teach as an adjunct faculty.”
