When Doug Kunz and his family moved into their Sunnyvale home in 2007, almost every appliance in the house used natural gas. They had always wanted to reduce GHG emissions from their home but weren’t sure how. Then, after reading up on new carbon-free technology and attending a speaker series from Sunnyvale’s Sustainability Commission, they realized the time to go carbon-free was now.

“It was like a light bulb went off and I knew I could convert our house to all-electric immediately!  The technologies for doing this are more mature and cost-effective than people realize. For example, our heat pump HVAC has a variable-speed compressor which saves money and keeps the temperature the same in every room. Basically, everything in the house runs more efficiently and I feel a lot better paying for carbon-free energy rather than paying to dredge goop up out of the ground and light it on fire. We haven’t burned any gas since last January.”
