Remember during Covid where every restaurant's menu was a QR code on the table that linked to a PDF in S3?

[^X] means any character other than X, so [^X]* matches zero or more of any characters, so long as none of them are X.

Yes the calculations are different for natural gas, I don't have that option. Rural properties here (south/central Ontario) typically use delivered oil or propane supplemented by f…

That makes more sense, but your utility's failings are not necessarily the same as mine nor anyone else's. I wish I'd never mentioned solar nor net metering now- I'm not on some cr…

Comment #45707090
The point of my original post was that I’ve seen a much greater ROI on my own heatpump than solar, even though I don’t regret the solar installation. I wasn’t making any claims abo…

It is for a fraction of consumers- power companies and governments are well aware of that.

I’m not sure what you mean by ‘unsustainable’ nor ‘critical mass’ here. Of course not everyone can net meter- on a sunny but mild day with no-one using A/C nor heating and everyone…

The issue for me with batteries is that in the summer I can produce in a day much more than I can use, and in winter I consume a lot and barely produce anything. This is where net …

I think the argument is that on average people are buying heat pumps and EVs faster they are installing solar panels but it’s not completely convincing though, power stations can b…

Yes the people selling solar systems all factor in aggressive future electricity increases, it's best to also see how it looks with more conservative rate increases. By my calculat…

Yes the figures are my approximate bills so include net metering revenues. You're right about the 8 year negative IRR for the heatpump, although I'm being very conservative about p…

There was a C$7k government grant at the time for the heatpump, which roughly matched the tax. The current Ontario solar grant is weird- it only applies to battery systems without …

People told me that, but I did the calculations myself and the impact on my energy bills is real. Net metering is essential though, so not everyone can do it. Compared to say SoCal…

I'm in Canada at a similar latitude with ground source, resistance heating normally kicks in at about -25C (-13F) or so, just a few hours on the coldest nights, doesn't cost much. …

The prices when I looked weren't that different- it was about C$30k Canadian for air source and C$40k for ground source (which I went with).

I'm amazed at these prices, I replaced a propane tank + furnace with horizontal loop ground source for $40k Canadian (+ tax, but government rebate matched that). It's almost paid f…

It's the opposite for me, much bigger ROI on the heatpump than solar. Rural property, 10 years old, ~3,500 sq ft + basement, in Canada where summer can be above 30C (86F) and winte…
