On a beast of a HVAC system, a simple 15A wall plug isn't going to cut it for powering the whole thing, but if the furnace runs off e.g. natural gas and you just want to power the blower off a 15A plug, that solves the problem of switching power sources.
The median reactor in the US produces 1-2GW. Most nuclear installations have multiple reactors, so capacity is a multiple of that. 1GW of solar generation requires literally millions of solar panels and thousands of acres of land, and still needs the transformers and distribution infrastructure. And that doesn't include any storage capability.
This is a contrived example. You're making it sound like solar is power available now. It simply isn't, on any scale like that. If it takes a decade to bring 1GW of solar online and two decades to bring 1GW of nuclear online, it's not as clear-cut.
Nuclear could be done a lot more quickly than it is and still be safe. Not as fast as solar, but it's not like it's an order of magnitude.
This article isn't about personal solar installations, in any event.
It's fine for casual game servers for friends.
It's not trivial to run your own email stack, but it's not hard either. It's more tedious than anything. Once it's up and running, it's low-maintenance. And it's fairly trivial to avoid spam. I get vastly more spam in my Gmail than I do on my self-hosted domains.
The biggest challenge with self-hosted email is getting an IP address that's not blocked or carrying low reputation. Most VPS IPs from e.g. Digital Ocean, Linode, Hetzner, AWS, etc. are going to get blocked from Google (the strictest) and Yahoo, Hotmail/Live/MS, etc. Cloud providers often block incoming and outgoing mail ports, too. I have a Digital Ocean VPS and my account is old enough to be grandfathered into the old policy, which means my email ports aren't blocked. I used to have no trouble sending email anywhere from my VPS, until I downsized it and got stuck with an IP in a bad reputation CIDR. Now I use smtp2go for relaying outbound mail, but still handle all inbound mail. 10/10 score on mail-tester.com, and I never have any problems or need to do any maintenance.
This is all pedantic. The point is that you can chain smoke quite a lot if you're dedicated. I've never met anyone who smoked more than two packs a day regularly or maybe three on a crazy night out of drinking and smoking. 4-5 is crazy.
The police want the capability. Flock just happens to temporarily have the better technology.
If you live in a dense city, there's a good chance you can reach an open network. When I lived in midtown Manhattan, there were around 500 SSIDs reachable from my apartment.
A TV not on the Internet is basically worthless these days, unless you have a third-party streaming device like a Fire or Shield--and then you're just moving the trust point from the TV itself to the streaming device, and the same concerns exist. Do you trust Amazon any more than you trust LG?
It's nothing more than purchasing votes with tax dollars and limited natural resources.
