I think there are solid reasons to believe that there is at least as much room for improvement in the nuclear industry as SpaceX demonstrated there was in the aerospace industry.

For sure! YC has funded several nuclear startups and hopes to fund more.

Note. Countries with the highest of
#nuclear#energy are Not the least contributors to#globalwarming
My2c:
Uranium/Hydrogen are not the way to a carbon free world
What we gain on 'clean' (energy) is lost on 'safety' or 'sustainability'.

What is the context though? Would they contribute even more without nuclear? Generally contributing a lot doesn't equate to it being due to using nuclear power.
-
Indeed. That's exactly why I only argumented on these countries with high nuclear power production not contributing in
#globalwarming reduction, since i cannot prove accurately for its increase. I suspect, but decided to play it safe
-
It would be nice if you knew though. My own take is, that the demand for electricity is likely not going down. Due to technological devices in homes & automation. So, you'd have to have tech that produces the same amount or electricity & emits less CO2, to blame nuclear power.
-
Just to clarify smthg though: i am not blaming nuclear power for global warming. Causes are known and easy to 'fix', we all are simply not ready for the tough choices that'd impact of current quality of life -- like trading big horse-powers with smaller, slower cars for eg. 1/2
-
I am stating that w overconsumption/overuse /overproduction we allow ourselves thx to cheaper (not anymore) energy sources, is neither sustainable nor a 'free pass'. Most centrals in France & elsewhere are way beyond their lifetimes, EPR is a €€ hole, Fusion is still scifi.

Nuclear share: France 75% US 20% diff: 55% Electricity CO2/total US CO2: 28% US/world CO2: 15% 15%*28%*55% = 2.3%

Ok, seems like "always" might be an important part. US emissions share decreased to 15% from 50% in 1950. 30% on average, 30%*28%*55% = 4.6%pic.twitter.com/sRcnImzndb

I know you’re just answering the question but I’d like to point out that it is misleading to talk in percentages when the absolute values keep growing so much. Thanks for the graph w absolute values!

Not quite what you're asking for, but if the US emitted the same amount of CO2 per capita as France, it would produced ~3.7 gigatons of CO2 and the total world production of CO2 would be reduced by more than 10%. (See https://data.worldbank.org/indicator/EN.ATM.CO2E.PC?locations=US-FR … and https://www.iea.org/publications/freepublications/publication/GECO2017.pdf ….)

A big chunk of the difference is that French people drive less, is smaller cars, etc.
-
Yes, there are definitely many reasons beside the part of nuclear in the energy mix, although this also a significant factor.

It’s ironic (and frustrating) that so-called environmentalists are the ones blocking us from picking the #1 lowest-hanging fruit to decarbonization

A big part of the death of nuclear was Three Mile Island. The primary cause of Three Mile Island was he usability problem caused by an unclearly labeled light for a valve. We could be using more nuclear energy if we had a UX engr with a label maker.

Can I tag this with a request for back of envelope calculation for how much less global warming would happen if we required US bound freighters to have emissions regulations. I bet it’s a multiplier over US power station emissions.
-
3.5-4% of global GHG emissions come from shipping (global, not just US), and the volume of shipping has more than 2x’d in the last 10 years (https://www.statista.com/statistics/264117/tonnage-of-worldwide-maritime-trade-since-1990/#0 …) so today’s figure is higher than historical average. US electricity contribution to GHG~5% of world total today
-
This is all answered in terms of today’s emissions of course, which isn’t what you asked for, but is probably enough ballpark context to suggest shipping isn’t quite as big a contributor as you’re implying
