@11112011 15 years yeah, but unless you can find some serious batteries....

@skells https://www.power-technology.com/projects/windfloat-atlantic-project/

@11112011 25MW lel

@skells that was just the pilot

@11112011 the problem remains - how do you match the grid load when these things drop off?

@11112011 you're gonna need a fuckload of hydro (also sensitive to climate conditions) or fossil fuels/nukes

renewables can be run as supplementary, sure, but not core energy

@skells u get it from other places

@11112011 that synchronisation fragilises the system in proportion to use of renewables

@skells the grid needs to match generation with consumption thats why crying that adding renewables doesnt make sense, u on the field of ideology

@11112011 it's not ideology it's electrical engineering

renewables (other than hydro) are volatile and you need alternatives when generation falls below consumption

@skells its pure ideology all added generation is gud

@11112011 don't have a problem with renewables, i have a problem with euro wonks blindly ideologueing the continent into an energy crisis

putin is just the catalyst, this sucker has been brewing for a while

@skells so u dont have a problem wit added generation independence

@11112011 ofc not

@skells

@11112011 yeah I know linked it last night

@skells so u know stop throwing ideolgy at me

@11112011

It's really not. Add enough renewables and you can have spot prices drop to zero, or even go negative. You're basically forcing the conventional providers to act as grid stabilizers for the renewables, meanwhile they don't get to sell electricity when the grid is producing.

@dave @skells prices down gud

@11112011 @dave

Legacy providers need to make money to stay in business dude. I know we *eventually* need to shut them all off, but (safe) nuclear is expensive right now, and miracle batteries are still 5-10 years away, just like they were 20 years ago. You can't shut them off until you have a real viable replacement.

@dave @skells nukes take 15 years to build

@11112011 @dave yeah, which is why it's fucked

Which is insane, because you know it didn't take 15 years when the shit was new. I hope SMRs take off and this becomes like a 1 year max process.

@dave @11112011 i think you need depleted uranium for the SMRs

FYI, depleted uranium is just uranium with most of the U-235 spent. That would be much easier to acquire/create than the enriched uranium that most reactors use.

But the only current certified design (from NuScale) uses normal enriched uranium anyways.

@dave i stand corrected

@dave @skells no one needs to make money

@dave @11112011 @skells

Can confirm, we get negative spot prices sometimes. In Australia they have negative spot prices during the daily solar panel peak.

In New Zealand we use geothermal, rather than nuclear for the base load electricity.

Our geothermal plants produce about 20% of our electricity.

You could build geothermal plants in most countries that have hot springs or volcanoes.

@DazzaNZ @dave @11112011 that's wild

@DazzaNZ @dave @11112011 what happens when you run out of magma

@skells @dave @11112011

The magnetic field of the planet will collapse and the atmosphere and water will be stripped off the surface the planet.

It will never run out in practical terms. If you look at the planet, it's 99% volcano, and 1% crust.

If reinfect the hot water after you turn turbines with the steam, then the system re-heats the water.

@skells @DazzaNZ @dave no no no renewables bad

@11112011 @dave @DazzaNZ geothermal is easily the most based of all power generation

@skells @11112011 @dave

Yeah, they are going to keep building it, out to 35% of generation. The hydro that's already been built will last for ages.

About 3/4 of the geothermal has been built in the last 25 years. They built the new ones when they understood what they were doing properly.

The first trial plant was built in the 1950s.

@DazzaNZ @11112011 @dave how deep do these things have to go, or is New Zealand just shallow for geothermal vents?

@skells @11112011 @dave

I think they are more than a kilometre deep.

Also it is not just used for electricity. Factories and greenhouses use it.

In Taupo, you can see giant insulated stainless steel pipes across the farm land taking the steam to factories.

@skells @DazzaNZ @dave when u live of exporting gas and oil like russia and u dont realy have that much use internely to it, all renweabes inur customers contries are bad

@skells @DazzaNZ @11112011 @dave "The industrial activity that expands relentlessly with developments in the natural sciences is basically a campaign to promote energy consumption. Its target has not been so much to boost energy production as to senselessly waste energy. As long as man continues to take the stance that he is 'developing' nature, the materials and resources of the earth will go on drying up." -Masanobu Fukuoka, The Natural Way of Farming, Natural Farming for a New Age

@dave @11112011 @skells

This is a good point.

The base load, geothermal, keeps everything going overnight, where stuff that stays on all night is the base load.

Then in the morning, they let water out of the top dams, which generates breakfast rush power.

The water runs down the river where a dam generates the lunchtime rush. Then later the dinner peak.

The dams store and don't generate if wind and solar are generating.

Gas generate for peaks responsive to sudden demand in Auckland.
