> The biggest retaliation the West can make right now is a commitment to a rapid exit at unprecedented speed from the oil economy, in favor of renewables.

You can't exit from the oil economy with renewable such as wind or solar due to their non-predictability.

If you want to stop importing Russian gaz, you need nuclear energy.

[danhor]

(all numbers for germany) Only ~14% of gas used is used for electrical energy. About 50% of the gas we use is imported from russia. 77% of the gas is used by households for heating (and also cooking, but that's negliable) and industry

To not depend on russian gas by reducing gas usage, the gas heating systems need to be replaced with heat pumps or something else and industry needs to shift, presumably to electricity (since it's unlikely that we have enough green hydrogen that's not produced from fossil fuels without depending on russia). This isn't going to be easy and unlikely to happen at a large enough scale in the next 5 years.

[flgb]

This is simply not true.

And even if it was nuclear is not a viable response with new projects taking decades to develop. Todays nuclear industry is delivering warmed-up 1970s technology that is expensive, slow, and inflexible.

Solar/wind/batteries with a small amount of backup capacity from hydro, power-to-gas/fuel, biofuels, or new long-duration storage is cheaper and faster to deploy.

>This is not simply not true.

You seem to be disagreeing with our greens. Gas is offered as the only backup source at that scale and timeframe.

>Solar/wind/batteries with a small amount of backup capacity from hydro, power-to-gas/fuel, biofuels, or new long-duration storage is cheaper and faster to deploy.

Wrong. [1]Nuclear wins out when kept open a bit longer and that is without accounting for storage methods. To say "a small amount of backup capacity" is absolutely ridiculous. The amounts we need compared to what is available right now would be massive. Most European countries aren't norway with loads of hydro capacity either. Also power to gas/fuel is a pipedream due to inherent costs and losses alone. You're better off making more pumped storage power stations like in Coo but those don't fit anywhere and aren't magical either.

[andromeduck]

The technology/resources for the storage required woudvtske even longer but you're right, we don't need new technologies, we should be serial building proven designs like CANDUs until SMRs hit stride.

[rplnt]

40% of EU gas is from Russia (and co.). Let's instead switch to nuclear where 60% of EU supply comes from Russia (and co.).

[londons_explore]

* but is worth far less, is easily transported so there is a worldwide market, and there are other producers in other bits of the world.

[Aeolun]

So we can just start using 50% less energy and there won’t be any problem.

[akvadrako]

Or local coal and gas reserves. The Netherlands has plenty of gas, they just choose not to use it. Germany has plenty coal.

[GekkePrutser]

That choice is because the emptied gas fields are causing earthquakes so there's good reasoning behind it :)

[henearkr]

But then you depend on West Africa for uranium. It's not a coincidence if Russian groups are in Mali, maybe they have an eye on Niger's mines.

[starfallg]

You can with storage systems albeit with lots of constraints. Having nuclear is important to guarantee baseload, but we can't rely on that solely either. With current gen nuclear tech, well also run out of fuel within a few generations.

[xroche]

> You can with storage systems

There is no such thing as storage systems at wide scale unfortunately

> well also run out of fuel within a few generations

Absolutely. But hopefully fusion will be around then.

[oceanofsolaris]

AFAIK the running out of fuel would be a non-issue with breeder reactors, which are disliked for the proliferation risk they are. Well, trade-offs.

Also: currently, nuclear fuel cost is a small part of running a reactor. If nuclear fuel follows a similar cost/available quantity curve as other geologic resources, we should be able to find more once we start looking in earnest.

[afroboy]

> you need nuclear energy.

Don't forget they are easy targets when war get declared.

[moonchrome]

I'm guessing if anyone is going to start nuclear war then we're going back to stone age with or without nuclear power plants.

[Hamuko]

Attacking a nuclear power plant in Germany is harder than turning off a pipeline.

[petre]

A gas pipeline is also an easy target unless it's under the sea like North Stream.

[arez]

so let's build some nuclear power plants, they should be done in 20yrs is that fast enough?

[modo_mario]

A serious stretch. Nevertheless the argument that they're too slow to build has been popping up for 20 years now.
