Fundamentally capitalism isn't about pricing things, it's about growth and extracting a profit.

Not on the right order of magnitude. We need to reduce our material consumption and energy consumption, even keeping them to the present level would not be sufficient, so for what you're talking about we'd need absolute decoupling

In a productivist system that is... The issue is that the options we have on the table at this point are keeping such a system (possibly not keeping growth going anyway I may add) and we’re pretty much guaranteed mass death or coming up wit

Surprised that nobody in the answers points to the levels of nitrous oxide emissions that nitrogen fertilizers brought along with them. At some point we have to decide which is worse: lower yields or hothouse earth...

There's still plenty of references and small but essential stuff. One notorious example that comes to mind is the KURL name that stuck: https://chromium.googlesource.com/chromium/blink.git/+/maste...

Arguably, licensing revenue was a drop in the bucket for Nokia and they had a lot more to lose with the liability that came from commercial customers. It was a hard move to (at least partially) undo for the Qt Company.

Considering we can't hold big oil accountable for burrying the lede on climate change, and electing to spread lies and cause confusion instead, I guess that's fair.

Some questions just shouldn't be asked if one is not willing to put in the effort to educate first. A recent poll in France found out that more than half of the people believed nuclear power was bad for the climate!

My point exactly, I refer you to the first sentence of the article, which I was criticizing: "Hydrogen, overlooked for decades by Germany’s energy planners, is gaining ground as alternative to fossil fuels as the nation scrambles to re

Just gonna have to shower your enthusiasm a wee bit on the electricity prices in France: they are rising steeply, but this is mostly for political reasons, as this was to allow the private sector to make money from the public nuclear produc

by elproxy 7y ago
Unlike fossil fuels, hydrogen is not a primary energy, so that article starts very poorly.

Don’t forget the PR aspect, and political cost. A lot of people in France believe nuclear power is carbon intensive because of the plume coming out of the towers.

I thought the cooling towers at Tricastin were only for the fuel enrichment part

The problem is regulations. If the river is already hotter than the max temperature allowed as output, then it’s not possible to operate, for regulatory reasons. Temperature delta is on the order of 0.1°C

Agree on most things except on the worst case scenario being constant with time. We should expect things to get worse and plan accordingly.

Also note that PV efficiency goes down with heat, so I fully agree with you that excessive AC reliance is a very real concern. Insulating buildings should be a big priority.

by elproxy 7y ago
The problem is two-fold: maintenance scheduled in the summer when the demand is “usually” lower. And stations operating with a river for cooling, where they have severe restrictions on many parameters, including maximum output temperature,

ITER will most likely be a big net negative, and the cost is much higher. Should we cancel it without trying then? If you consider Superphenix as a prototype shut down prematurely for political and ideological reasons, the numbers aren’t th

There's a lot of irrational talk on nuclear (which one could even be tempted to suspect was the result of astro-turfing campaigns by oil companies), I find this is a pretty decent starting point to question mainstream opinions and beli

I think the key technology when looking at extending supplies is fissile breeding, so you probably want to look at fast neutron reactors, and since you quote the french wikipedia, I will follow suit: https://fr.wikipedia.org&#x2F

I think orders of magnitude are in different leagues, a quick indication being the relative shares of fossil fuels and wind/solar in global final energy. Our best bet for carbon capture is probably to be found in the plant kingdom.

by elproxy 7y ago
The CO2 we’re putting in the atmosphere from the combustion of fossil fuels will be there for 10000 years. Current nuclear waste is essentially harmless in a few centuries.

Your math is off on the current scale of wind and PV and the time it takes to get it anywhere significant. Plus you are forgetting storage and infrastructure costs due to the intermittent nature of these sources and the imposed load factor.

Hydro is finite... When you've harnessed 80%~90% of the potential, that's about it.
