Notes -
Then nothing is cost-effective except for fossil fuels and hydroelectricity, ultimately.
But we already knew that; that's why banning their use is such a powerful socioeconomic weapon. Nuclear just happens to be both the closest you get to viability (since the plants from the '70s and '80s seem to be doing just fine; that was back when construction and labor were way cheaper though) and something that's arguably worth funneling research dollars into from a materials science perspective.
This line always frustrates me because this is an isolated demand for rigor. Mine drainage (and it is a rather interesting flex that a modern mining company saw fit to name itself after the most expansive environmental mining disaster zone in human history- that being the Rio Tinto, which is what that's a picture of) will kill future Fred Flintstone far more quickly than anything else will. Fortunately, we discovered radioactivity before we invented the backhoe.
And I get that you have to convince John Q. Public of that, who will never come around in their lifetimes thanks, ironically enough, to radiation exposure (they sat too close to the TV while watching Simpsons reruns). Which is why you basically can't do this until you have a military that will deal with that.
Correct! Hell, forget about cost - there is no viable replacement for fossil fuels.
Nature is already going to do that for us - not only are the fossil fuels going to eventually run out, rational human beings prioritised the easiest-to-access and most efficient stores of fossil fuels. The energy return on energy invested of conventional fossil fuels is going down, and the EROEI of shale and fracking is even worse.
No, not at all. I believe mining should be heavily regulated, especially when it comes to disposal of hazardous and toxic wastes. Allowing people to pollute and destroy the biosphere imposes immense costs on the rest of society - it is a form of abusing the commons, and is ultimately substantially more expensive than properly disposing of the waste. It's just that the cost is paid by the rest of society as opposed to the mining companies.
How long are you going to be waiting? We've already hit peak conventional oil, and tight oil is significantly less competitive on an EROEI basis (which is the only basis that actually matters). Nuclear power, barring some great new discovery or innovation(which, to their credit, the Chinese may have actually achieved), will remain on the shelves in most cases because it is just not capable of functioning as a viable replacement for fossil fuels due to the poor EROEI.
Isn’t there quite a bit of easy to access fossil fuels that are off limits for political reasons, eg Venezuela’s dictator not trusting anybody capable of drilling?
Venezuela's oil is notably low quality and requires extensive processing before it is usable - and they actually are drilling for oil anyway for export to China. The last time I ran the numbers, Venezuela's oil reserves, if totally extracted, would be able to power the current global economy for less than a decade assuming zero economic growth. While there's likely to be significant demand destruction due to the US economy imploding to the degree that the administration won't even publish the numbers anymore, Venezuela's oil just isn't worth the squeeze - and even if it was, it won't last for long.
