Canary Media’s Electrified Life column shares real-world tales, ideas and insights to demystify what people can do to shift their properties and lives to wash electrical energy.
Cutting fossil fuels out of our properties and commutes is usually a formidable problem. But the local weather dividends can be big: greater than 40 % of U.S. vitality emissions come from our home equipment, house vitality sources and automobiles, in line with electrification nonprofit Rewiring America.
In 2022, Judy Ko determined to take up the problem and begin electrifying her 1965 San Francisco house. The principal of climatetech consultancy LK Hillside admits that, despite the fact that she’s a clean-energy knowledgeable, the challenge was a bear. “I wasn’t in a position to deal with it till I had a six-month sabbatical,” she advised Canary Media — a chunk of time most individuals don’t have entry to.
Her house isn’t completely freed from fossil fuel — the fuel range lingers — however she’s made immense progress. Over a 15-month slog, Ko has efficiently swapped her fuel furnace and water heater for an uber-efficient warmth pump and heat-pump water heater, put in insulation and purchased an EV. She additionally put in photo voltaic panels and a house battery to energy her house and automobile.
That makes Ko among the many early movers towards an electrified life, and her still-ongoing journey is rife with classes that would assist the remainder of us. Canary Media caught up together with her to ask about how she managed it, what tasks have been hardest — and what advantages she’s reaping now.

There are so many items to electrifying our properties and automobiles. How did you determine the place to begin?
Our sport plan was based mostly on: What is the pure finish of life for among the massive items of kit or parts of the house? When is it time to redo the roof? When are our furnace, water heater and automobile getting near their finish of life?
Part of it was additionally [asking] what’s the most important bang for the buck. We knew insulation would make a actually massive distinction.
So we determined to go forward and do the insulation, the photo voltaic and the warmth pumps. And the sequencing was logical. For instance, roofing is tied to whenever you set up the photo voltaic. And we have been making an attempt to dimension the photo voltaic system to account for an EV and warmth pumps, so I labored with the photo voltaic firm to estimate the variety of panels.
I additionally spoke with QuitCarbon [a home-decarbonization company based in California]; they helped me assume by all the items.
[And] I talked to my electrician, who I’ve used for a few years. But he’s clearly influenced by the conservative media’s tackle all this local weather stuff. He was pooh-poohing warmth pumps: “Natural fuel is nice. If you get a warmth pump, the grid’s going to break down!”
Did he stay your electrician for the heat-pump job?
No, I ended up working with another person. I nonetheless like him; I work with him on our regular electrical jobs. But he was sufficiently skeptical that I wished to work with somebody who was extra on board.
You tackled a big selection of home-decarbonization tasks with various ranges of issue. What have been the simplest tasks, and why?
The photo voltaic set up and the re-roof have been simple. We have been capable of finding a native contractor that was in a position to do each. They have been additionally, frankly, a excellent contractor: well-organized, simple to work with, good communications.
They additionally ended up doing {the electrical} panel as a result of they’ve an electrician in-house. Later, they put in the battery. Having [a contractor with] three trades in-house — the roofing, the photo voltaic and electrical — made issues a lot simpler.
And these tasks have been additionally simply not that invasive. The electrical panel and the Powerwall [home battery] are down in our storage space; if we lose that area for a whereas, it’s not a massive deal.
Replacing the water heater with a heat-pump water heater was additionally fairly simple.
Let’s get to the juicy stuff. What was the toughest challenge? What challenges did it throw in your means?
Going from a fuel furnace to a ducted warmth pump was a little painful as a result of we needed to redo a few of our ducts. Heat pumps want a increased quantity of air circulation to work as a result of the temperature differential isn’t as sturdy. [Editor’s note: In some cases, but not all, switching to a heat pump may require getting larger ducts.]
