GHANA TO SELECT NUCLEAR SITE IN 2022

Ghana is tired of running short on generation, and is advancing from its existing nuclear research reactor program to a full commercial nuclear energy program.

Ghana can be the Sweden of Africa, blending existing hydro with new nuclear.
I visited Ghana's research reactor in October of last year.

It was cool but the real highlight of my trip was a conversation with Dr. Stephen Yamoah, director of Nuclear Power Ghana, who is quoted in the GhanaWeb article.

He had a clear vision and a plan. His team is executing.
Intriguingly, the Ghanaian nuclear program has attracted a proposal from SNC-Lavalin to build CANDUs, which if built would be the first CANDU exports since Qinshan in China twenty years ago.

It's surprised observers in Canada who thought the CANDU new build era was over.
Part of what's so exciting to me about Ghana's progress is the message it sends to neighbors like Nigeria, with 200m people, and like Ghana, extremely low land and sea wind speeds, and middling solar potential.

Get going or get left behind: West Africa's future is in nuclear.

INDIAN POINT NUCLEAR CLOSURE ALREADY CAUSING ENERGY SHORTAGES:

There's not enough natural gas to feed both the city and all the replacement gas turbines built to accommodate @NRDC's campaign to switch New York to 100% fossil energy.

We predicted exactly this.
NRDC hired their own energy experts, whatever frauds would come up with the obviously wrong answer that the city's biggest power plant, only significant one not powered by natural gas or fuel oil WASN'T NEEDED in an area with severe gas supply constraints

People are going to push back and say that these are customers who chose to be on interruptible service to save money.

The problem is that without Indian Point, the city's strongest defense against extreme cold has vanished.

2GW of nuclear once displaced 6GW natural gas heat.

It takes remarkably little exposure to large solar projects and their developers before people realize it's actually industrial energy production, and a particularly low-fi form at that.

It's the opposite of the journey people take when discovering nuclear, typically.
Solar in theory: wow free energy from the sun! Heck yes!

Solar, reality: what the hell just happened to our community. Where is our forest

Nuclear in theory: seems odd...I get bad vibes from it

Nuclear, reality: this place is incredible and it's surrounded by nature! I love it
To say the very least, this increasing pushback solar and wind experience with increasing pubic exposure is rarely considered in spreadsheet decarbonization.

There's a reason Germany will have to substantially curtail local democracy to force wind turbines into its forests.

"WHAT ABOUT THE WASTE?"

Nuclear energy's got EXCELLENT waste: there's almost none of it, and it announces its presence reliably even w/ cheap detectors.

The Dutch have solved it: make the place with the waste HIGHLY ACCESIBLE, CLASSY, and most of all, FUN.

@ParisOrtizWines
The physics and engineering of shielding and storing even the spiciest nuclear wastes are simple.

Social and psychological challenges cause people to ask "What about the waste?"

So the Dutch hired top artists and architects for @COVRA_nv

Engineering + pure vibes = waste SOLVED
If everyone with nuclear reactors built their own @COVRA_nv and schoolkids and politicians and cultural leaders got to hang out & vibe with their nuclear waste like we did here, there WOULD BE NO NUCLEAR WASTE PROBLEM.

At a fraction of the cost of silly holes like Yucca Mtn.

MESSAGE TO ENERGY MODELERS:

You must model the loss of transmission lines. You must model continent-wide wind droughts. You must model continent-wide droughts that knock out hydro.

If you're still selling 100% Wind-Water-Solar after that, you're a knave or a fool. Or both.
I don't have to model these things because I fundamentally distrust giant intricate energy models.

Shit goes wrong. Big shit. Crazy shit. Shit that's never gone wrong goes wrong.

I didn't predict what's happening now in the UK specifically, but that's the point: YOU CAN'T KNOW.
Texas weirded me out.

How it had been managing to have such crazy low revenue going to generators, but seemed ok.

How it was running with lower and lower reserves each year, but appeared to be fine.

Until it wasn't.

After the fatal blackouts energy modelers got another try.

ILLINOIS SENATE PASSES THE BILL

BYRON LIVES DRESDEN LIVES

THE NUCLEAR PLANTS WILL LIVE FOREVER

VOTE WAS TIGHT, MARGIN OF 1, DOESN'T MATTER
Brussels erupts in cheers, nuclear advocates from around the world cheering Bryon, Dresden, Chicago, Illinois, USA, and nuclear plants fighting for survival around the world:
We must never lose another plant!

GERMANY: We must not lose Gundremmingen in December! We must not lose Grohnde! WE MUST NOT LOSE BROKDORF. Image

The general public has a misunderstanding that somehow, energy experts have found a way around wind and solar coming and going.

It's not true. THREAD.

Here we have Chief Energy Correspondent at Bloomberg News @JavierBlas patiently explaining record prices to a curious follower:
No matter how many tens of billions of £ are spent on wind and solar energy in the UK, it still turns off more or less daily.

It turns off in the UK as it turns off in surrounding countries.

There's no solution except more gas or electricity rationing.

Now gas is expensive.
This problem gets dramatically worse as you get more wind & solar, as these energy types soak up power system revenues when they're on, but must be expensively made up for when not on.

And more wind and solar means weather prediction errors become much more costly for society.
