If you're considering the total cost then you have to factor in the entire reason to electrify which is the environmental cost of continuing to burn dead organic matter. In that case, electrification is absolute bargain.

to what end?

I just said. To reduce environmental impacts. A fully electric factory drawing power from a grid of renewables is cleaner, safer and more stable.

so it sounds like "bear infinite prosperity / comfort / security costs for dubious environmental benefits" . Have you thought about how to weight the costs vs the benefits? Are you proposing being poorer, hungrier, more miserable, less comfortable in the hot & cold season for "clean energy". so how much are you willing to sacrifice for it?

Nothing and we don't have to and idk what you're talking about. I literally have an all-electric home and it's perfectly comfortable. Heat pump works great on the hottest and coldest days (outside temp has been as low 2F as high as 99F). And security benefits are also very much in favor of renewables. There is no global supply chain for wind and sun in the hands of a cartel. You have been suckered by a lot of industry propaganda.

residential is a small piece of the pie
