If only it were possible to permit and build the things in some kind of reasonable time frame....

The problem with sloppy work is that the supply FAR EXCEEDS the demand

 

[SlideRuleEra]

.... and at a price per MWh that's even close to competitive with other clean energy sources.

Fairly ridiculous piece. I don't say that because I am for or against nuclear energy.

My question is always: what will we do with that doubled amount of energy ?

what will we do with that doubled amount of energy

All those electric vehicles require electricity to recharge the energy expenditure that would otherwise come from fossil fuels. A Tesla going full range requires 55 kWh of energy recharge coming from the power mains. There are supposedly 7M electric cars, so that would be 385 GW*hr of electrical capacity, for every 7M additional electric cars, assuming they were all Teslas and all running fully range over some number of days.

Additionally, if we are actually going to stop or slow down using fossil fuels for power generation, there may not actually be any extra energy

Mine Bitcoin, duh!

Sure, nukes would help reduce the amount of CO2 from power generation, and there are many opportunities to replace FF power with electricity, with presumably acceptable limitations, restrictions, and costs.

In the 1st world there are probably surmountable problems ... where to get the "rare earth" metals for the batteries ?
The other key 1st world issue is ... what about those other things we do the create CO2 ? (like AIUI cement/concrete production ?)

The bigger question is for the 2nd and 3rd world economies ... are we going to deny them cheap FF energy ? Can we even deny them burning coal ??
Is it "better" for them in the long run to leapfrog FFs and go directly (with 1st world support of course) to an electric economy ??

another day in paradise, or is paradise one day closer ?

As to your second question, I don't think reliving history is necessary for each country. In a unicorn world somebody would develop a safe cheap nuclear power station that uses low grade fuel and is sealed for life. these could be deployed worldwide. In the real world however the entire nuclear industry is tied up in so many knots that this won't happen. Perhaps Mr Musk could stop tweeting and fund something useful.

I propose a thought experiment.

The manufacture, deployment and maintenance of renewable energy equipment and resources is to immediately cease all use of non-renewable derived energy. This includes, among other things, all manufacture, transportation, installation, commissioning, maintenance and repair of wind turbines, solar electric and solar heating equipment and batteries.

Prove that it works

Well that was a complete point miss!

Well that was a complete point miss!

I had to go back and re-read your message a few times to understand what you could have been saying that was missed. When you said, "what will we do with that doubled amount of energy", I take it you mean.... that expanding nuclear is only worthwhile is we take other fossil fuel power plants off like.

 

[LionelHutz]

LOL, and people wonder why this forum fails.

Global energy needs are rapidly increasing. Electricity demand alone is projected to double in the next three decades. However, a key question remains. How can we effectively offer abundant clean energy globally?

 

[rb1957]

I'd accept "fail" if you mean "fails to accomplish anything useful".

As a "passable waste of time" it's quite entertaining ...

listen ... (shouts) in-coming !! ...

another day in paradise, or is paradise one day closer ?

 

IRStuff,

And what will we drive all those EVs on, yellow brick roads? Situated only on wasteland?

Almost all of the technical 'solutions' I see being proposed fall into the fantasy category of 'having your cake and eating it too'. We consumers (formerly citizens) love to hear it, and politicians are congenitally incapable of telling us different. Their careers depend on it. The naive author of the powermag piece writes literally those words in extolling the virtues of nukes.


"Everyone is entitled to their own opinions, but they are not entitled to their own facts."

 

[LionelHutz]

rb1957 - yes, completely useless so far.

 

[IRstuff]

And what will we drive all those EVs on, yellow brick roads? Situated only on wasteland

And NOT driving EVs is a better solution, how? We're decades, if not more, from full EV usage, if ever; there are some fundamental blocks that might never have a clean solution, one of which is that recharge time of the EV is currently quite high, which is a point of resistance, at least for me.

If every car factory in the world switched to EVs only tomorrow, it would take 20 years to replace the global fleet of cars. (That is, the global fleet is 1.4 billion and the best year's production is around 70 million). It's going to be a long journey. In reality of course what will happen is that rich countries who care, and can afford it, will go EV first.
