Best to think of fossil fuels as a shot in the arm of the development of human civilization. On that timescale, It was always going to be temporary, whether due to climate change or simply the limits of availible fuel. We were always going to need to use it to bootstrap onto something else within a couple hundred years of the invention of the steam engine. The math is reasonable and yes, total solar power isnt a problem (storage and distribution is, but total availability isnt hard).

Hydrogen is just portable energy storage. Different problem than generation.

And yes, heat pumps run down to -20C or so now.

Everybody tests their backups. Some people even manage to test their backups before they need them.

I see this all the damned time. Some people are obsessed with pages breaking at a heading or figure so they insert manual page breaks all over the damned place.

Even the slightest font kerning difference and you end up with blank or mostly blank page when some manual page break gets pushed to the next page.

Delete the manual page break that never should have been there? Nah, just cancel everything.

I swear I have been reading this article for 20 years. Some gov org balks at Microsoft cost and pitches free alternative. They dont plan on spending extra to complete the transition and then dont adequately train or build out the infrastructure.

Replacing an intrenched system with a free software alternative successfully will require more money in the first few years, not less.
