Rajneesh Bajaj wanted his home to serve as a model for achieving the zero carbon goals that were established by California’s energy bill, SB 100, an environmental measure committing the state to running on 100% clean energy by 2045.

“I aspired to live in a home that is not only energy-optimized to the highest level, but also optimized for functionality, comfort, convenience and least impact to the environment. Being a chemical engineer, I clearly realize the challenge of becoming carbon-neutral but I believe that goal is achievable with the technology and equipment available today. If properly designed and installed, all-electric systems do not pose any challenges. In fact, the quality of living is the same or better than with other gas or hybrid systems.”

He began by installing a PV rooftop solar system, followed by a heat pump water heater and HVAC.

“A heat pump water heater does have some noise (like a refrigerator) but with appropriate location and sizing works as well as a gas-based heater. I also installed an induction cooktop, which has significant safety and efficacy advantages over natural gas stoves.

“Now my average net energy bill is $0 – 50/month, and that includes complete home heating, cooling, water heater, induction cooking, as well as charging two electric vehicles that are driven a total of approximately 15000-20000 miles per year.”
