“Making the switch from methane helps all our communities and region address some of the fastest growing sources of heat-trapping pollutants responsible for our changing climate,” San Mateo County Supervisor Dave Pine, who also is a Peninsula Clean Energy co-founder, said in a press release.

Unfortunately, I don’t see a lot of money being saved as the issue is still the out-of-pocket capital costs to purchase and install replacement units (a loan is still a capital cost). There are no numbers showing return on investment (ROI) so allow me to take a gander…

If we look at PCE’s Joint Rate Comparisons paper, we can see that a 50% renewable rate, you may save between $3 to $10/month. If you opt for the 100% renewable plan, you won’t save any money. You’ll pay around $1 to $4/month more for your electricity. I’m ignoring the third PCE plan which is not “clean” as around 1/3 of the energy is from natural gas. Now I don’t know how much a new electric heat pump HVAC or water heater costs, but it won’t be zero, even with rebates. Let’s assume one has a net cost of $1000 (highly doubtful, but if you can bear with me…). If you opt for the 50% plan, it’ll take a little over 8 to 27 years to recoup your investment. On the 100% plan, you’ll never recoup your investment, you’ll go negative. Now if you double the net cost to $2000, it’ll double your ROI to 16 and 54 years, respectively. Of course, this example holds true only for electricity usage. I haven’t factored in gas costs and I also haven’t factored in the increased use of electricity due to all-electric appliances. Will these two costs cancel each other? Someone else with more time can do some calculations. Please, if anyone cares to, check my math – it’s sometimes hard to do math while on a Zoom call. Or provide a counterpoint, along with numbers.

The bottom line (whether my math is correct, or not) is whether it is worth the capital outlay to convert to all-electric, knowing that electricity continues to be provided mostly by fossil-fuel burning sources. Will you stay in the house long enough to receive an ROI? How many times have we had gas outages compared to electrical outages? How many times have we been told to conserve on natural gas to keep the “grid” from going down? Your house, your money, your choice. If you plan on going for it, take advantage of subsidies while you can. Otherwise, when it’s time, you may just want to replace your current electrically operated appliances with Energy-Star certified appliances. Hey, it’s a perfect time to ask the significant other if you can replace that old TV with a new one. You can take comfort knowing you’re helping to save the planet. As a plus you’ll have a new TV with new bells and whistles. Of course, dispose of your old TV responsibly.

But Terence, you just don't get it. You will be saving the planet, isn't that important enough? As far as the financial aspect is concerned, someone will have to pay for the interest free loans. That will likely come in the form of a surcharge for all PCE customers who still think they are helping with the mitigation of climate change.

From various impartial websites one can determine how cost effective these heat pump installations are. They are not, unless of course the cost of natural gas is skyrocketing. We should learn from the current situation in Germany and The Netherlands where energy costs have gone through the roof and many millions are now sitting in their homes without or with limited heat. I have no issue with this all-electric conversion but all who contemplate it should be fully informed of the economic and logistical consequences. As you have mentioned, there is little or no information on this important topic. And lastly, unlike PG&E, PCE is not a regulated energy provider and can raise rates at the behest of its Board. These are all Greeniacs, so be aware.

Dirk, you are so right! Shame on me for not caring about the planet even though China, India, and other developing countries continue to use fossil-fuels to their heart’s desire. Perhaps I’ll cogitate upon the error of my ways as I fly off for another vacation. Maybe when I return, I’ll be able to read about the costs of conversion and their performance from folks with personal experience.

I guess the next step is they will have a down payment program and try to fund housing for those who agree to go all electric.
