Dams + renewable energy is a perfect combination. Transmission capacity is cheap and long lasting, why anyone worries about transmission is beyond me, it's like saying you shouldn't buy a TV because of the cost of the HDMI cable.
Yes, Europe imports/exports energy, in the UK we're actually building (more) transmission lines to Norway just to be able to use their pumped hydro. We're also considering lines to Iceland and we have lines to France.
Unless you charged your electric car during the day in which case it could give a few percent of it's storage back at night, with led lights, TVs etc you wouldn't need much.
As I understand it, earthquakes are kind of like that. At millions of points along a fault, various rock structures prevent the plates from slipping past one another. Periodically, those break or shift, allowing the plates to continue sliding. An earthquake occurs when the stress becomes sufficient to cause one of those rock structures to break or shift so that the plates can move again. The size of the earthquake is proportional to the amount of pressure that was on that structure prior to when it broke or shifted. So to predict an earthquake accurately, you would need to know the stress on not the fault as a whole, but at least ostensibly on every single rock structure of a given size or larger within the fault system.
And of course some rocks are stronger than others depending on composition, pre-existing cracks, rock orientation (because of the grain).
Some interesting stuff there. But more data is certainly needed, the way people got ill in the lead up to an earthquake is fascinating, but again there could have been a separate cause.
Or like throwing that tennis ball at the lever that releases the ship from dry dock - a few megatons might just be enough to start something which is already close to happening.
Fracking causes earthquakes so you can't say it's not possible.
Can we measure them indirectly? - Honest question. I don't know if GP post is correct or not, it could be that when stress reaches a certain level an earthquake will occur. Obviously you'd never know down to the second, but could we ever know down to the day.. month... or year? How chaotic is it?
Maybe it'd be possible to deliberately set off an imminent quake, doing this could save a lot of lives as you could get everyone to safety 1st. I'd love to hear an experts opinion on this
We have a vastly superior knowledge of items in images and videos, we understand information about colours, materials, living things, the way physics interacts with these things, what's flammable, floatable, destructible, cheap expensive, natural, man made and countless more attributes. We understand these things, we don't just attributes words to them when we don't even comprehend the meaning of those words.
Look at Eliza bots, they basically talk meaningless gibberish, sometimes they get lucky like a human who doesn't know the answer to a question but answers yes or no regardless.
There's no doubt that we will soon reach a point wherein solar and wind will be readily available...
FFS wind and solar are just too of over a dozen ways to harness renewable energy. And what on earth is 'will be' there for? Solar and wind are readily available now.
Other renewables types and ways to move over include:
Tidal lagoons, tidal streams, wave power, dams and pumped storage - several types including compressed air underground, underwater and dual reservoir. Solar panels, solar water heating, concentrated solar and this including molten salt storage etc. Geothermal power generation and geothermal home heating. Air-source and ground source heat pumps. Fusion and cold fusion*. Battery technology is going nuts right now, cheap battery tech that could store vast amounts of grid energy using some of the most common elements is currently being developed, for example Materials discovery for earth-abundant battery | UTokyo Research.
And then there's 'time-shifting' which would be a lot easier if all vehicles where electric or some electric some hydrogen etc. These vehicles could be charged when renewables output is high.
Energy ratings could be vastly improved, the creators of consoles and computers could be moved to improve standby energy use and have default energy profiles which save energy quicker.
Home heating systems could be vastly improved, it could be mandated that all new radiators have indiviual temperature monitoring and remote setting capability, we've had the technology to be able to do this for decades already. Heating a whole house 24/7 when half the rooms aren't in use is very wasteful. Energy taxes should escalate with usage / waste, the 1st 10kwh / day tax free, the next 10kwh/day taxed higher etc or something along these lines.
Country of origin labelling should be mandatory, for example I bought an apple the other day which it turn out had come from the other $%^&ing side of the planet, I didn't know this because UK supermarkets don't have to say where food comes from.
Just saying we can't power the world with wind and solar shows a complete lack of understanding of renewables and ways to go 100% renewable.
I wish they'd stop calling this stuff A.I. it's simple pattern recognition. There is no such thing as an AI that has any kind of comprehension and it doesn't look like there will be any time soon.
And this stuff will likely be driving cars and trucks, I want to know every detail of how it can fail beyond the obvious ie that it can't tell the difference between a dress and a cat or a face and two giraffes etc.
Which is besides the point, the trucks don't need to be fossil fuel powered and I said vehicles, not trucks, many vehicles could be electric or hydrogen etc, particularly taxis and buses.

Yes I support nuclear, and I support solar and wind, but those not familiar with the power industry don't realize how delicate a balance the grid is with supply and demand. There has to be a source to keep the grid stable with the varying wind and solar input. The best choice for that is nuclear be it fission, or fusion.
Eh? Nuclear is useless for load balancing, it supplies a continuous output. And the cost of nuclear at 90% output is not much different from the cost of nuclear at 45% output so if you reduce output to 45% then the cost per kWh almost doubles - and it's already expensive to start with.
There is no point in backing wind/solar with ordinary hydro because you might as well just use the ordinary hydro and forget the wind/solar.
Wrong, the point is you double your capacity annually, there is a finite amount of Hydro, very few countries can get 100% of their electricity from hydro, if you can get 50% of your need from hydro then you can simply get the rest from wind + solar.
And if you can get 50%+ of your electricity from hydro then why not produce > 100% from renewables and sell the excess.
I was going to mention pumped hydro but didn't, Canada has huge pumped hydro potential no doubt but I wanted to keep it simple.

Iceland, can it even grow it's own food?
Yes, Europe imports/exports energy, in the UK we're actually building (more) transmission lines to Norway just to be able to use their pumped hydro. We're also considering lines to Iceland and we have lines to France.
Sure, if you ignore all the external costs of coal.
Unless you charged your electric car during the day in which case it could give a few percent of it's storage back at night, with led lights, TVs etc you wouldn't need much.
You think being a wage slave is better than taking holidays? why is productivity so important to you, you own a lot of shares?

You get all of your power from hydro, install extra turbines if necessary.
Eh? Nuclear is useless for load balancing, it supplies a continuous output. And the cost of nuclear at 90% output is not much different from the cost of nuclear at 45% output so if you reduce output to 45% then the cost per kWh almost doubles - and it's already expensive to start with.
