I don't know - to all of the above.
I'm convinced that combustion-based energy technologies have overtaxed
planetary resources to the point that there is no longer any upside to
their continued use on any significant scale.
Can't disagree, but the ratios do matter.
If fossil fuel is 1% direct heat and 99% global warming, one might conclude
that nuclear energy is a viable alternative for generations.
A cursory review of our "peak wood", "peak whale oil", and "peak
petroleum" experiences leads me to conclude that fueled technologies all
ultimately lead to some "peak fuel" point.
Seems to me that it'd be smart to choose technologies that don't have
downsides.
Yeah but...you have to have viable technologies to choose from.
The human race is selfish and greedy.
I've cut my carbon footprint in half over the last few years.
I could do more, but I'm greedy.
I like long, hot showers.
I can afford long, hot showers.
I'm not gonna stop just so there'll be more energy so YOU can
take a long, hot shower in my place.
The human race is also very resourceful in fixing problems.
But they don't care until it affects them directly in ways they
can't tolerate. In this case, by the time that happens, it'll be too late.
I take great comfort in the fact that I have no descendants and
will be dead by the time it happens. There's that greed again...
