can solar run 24/7 factories?? it's not that simple guys
With the help of electrolysis and a gas turbine, it can. The problem is that we don't have enough solar panels and not enough electrolyzers.
Tangential: is the unit kWh/h a standard in the industry? It hurt my brain until I canceled the hours and got kW. (Yes I know kWh is a widely used unit of energy)

It does not have to be painless. That's fine, it's a minimal price compared to what's happening to Ukrainians.
That's been my argument to friends and family this week. If an extra dollar per gallon is what it takes for fewer Ukrainian children to die then that's what it takes.
· We should put extra dollars not to buy goods from Israel, so fewer Palestinian children die
· We should put extra dollars not to buy goods from the US, so fewer Syrian children die
· We should put extra dollars not to buy goods from the UAE, so fewer Yemeni children die
· ...
I'm afraid I don't have so much money.

Putin’s and his inner circle’s plan was that it will take 1-4 days to take Kiev and two weeks to take most of Ukraine. Minimal resistance was expected. The window of opportunity with this expectation is from mid-December until end of February. They picked a date with this plan.
> Putin’s and his inner circle’s plan was that it will take 1-4 days to take Kiev and two weeks to take most of Ukraine. This is being said a lot these days, but I haven't seen any proof of it. I'm not saying that proofs don't exist nor that it's wrong, just that I've been reading it everywhere, and haven't seen evidence. So I'd be happy if someone reading this could point out to some clues

I never knew until recently how tied up Russia's oil strategy was to their military / political thinking. If others are interested, this video has a great overview: https://www.youtube.com/watch?v=If61baWF4GE
Gas and oil is all they have to trade and they have a lot of it.
Since new investment into fossil fuel projects will go to nearly zero from here (and old equipment becomes defunct unless it is replaced), expect there gas/oil exports to decline significantly in the next years/decades. Putin didn't only mess up Ukraine now, he also wrecked his own country for at least a generation to come.

I am certainly empathetic to having power and lights go out... In the midwestern USA, we survived last year with rotating blackouts during an unexpected winter storm that reached deep into Texas to parts that haven't seen snow in 50 years, and some parts ever receiving snow on recorded record. That being said, people are dying because of cheap power and gas. I know it's easy for me to say halfway across the world fro…
While what happened in Texas is good for empathy, it’s not exactly the same. The power outages there were due to a poorly regulated electrical market where the power stations froze in predictable ways. Notice that it was only Texas utilities that experienced the most major issues.
Situation in West Europe is also based in energy politics, a lack of energy security planning, and no impact studies from shutting down nuclear power plants.
There are parallels in my mind in that both are a product of short sighted ideological thinking.

What's the round-trip efficiency of such a system? There are multiple lossy conversions, you'd be doing well to hit 50% if the gas is simply burned to spin a turbine.

More convinced that the only thing stopping wars will be energy abundance not reliant on fossil fuels. Countries will still fight over natural resources, but probably less
