Onshore, Europe has enough wind potential to power the world.
https://web.archive.org/web/20231004055500/https://www.bbc.c...
Currently we have 14.7 GW of operational off-shore wind gen. Another 13 GW is in the planning stage and 46 GW more in the "early planning" stage.
There's currently 14 GW of on-shore wind gen.
Is there an API to monitor prices?
I ask because I frequently see posts like this one, but then also that Europeans are paying more than ever etc. Hard to figure if we are putting a dent in anything.
It has worked out great so far, some days when there isn’t much wind can be painful but overall it works out better. Even if it didn’t, I’d rather pay a fair amount than have energy companies rip me off.
There is a massive shortage of Scottish -> England transmission though. So it's a lot better to build them closer to where the power is needed.
However, there is nearly 10GW of HVDC in the pipeline to transmit power from Scotland to England (look up national grid eastern link 1, 2, 3 and 4).

There's also major potential for wind farms in Wales, although it's been controversial since some of the sites are on top of peat bogs or scenic hills.
>Scotland finally leaves (I am still certain it will happen in my lifetime).
Scotland could aim for a Channel Islands-type arrangement where they still enjoy an economic union without an administrative one. That would be similar to the situation that existed before the Acts of Union. Of course, they're quite a bit bigger than Jersey, so it could be tricky.
Besides, the European electricity grid is much larger than the EU, it spans all the way from Ireland to Turkey, and from Finland to Morocco.
* Actually, many of them are owned by non-UK governments.
I remember reading a few papers about essentially underwater turbines in tidal estuaries. Where you have natural flow of water that you can just tap. If I recall correctly impact on local wildlife (seals iirc) was lower than expected.
Main argument I could see was that water had 1000x the density of air so 1000x the amount of power for a rotor with the same swept area. Of course fluid speeds are lower so it’s not quite that easy. But much more predictable. They did some fancy optimisations in the blades and came up with decent efficiencies. It’s a great little series of papers by Batten and Bahaj et. al from 2006.
I assume the art has progressed since then.
But yeah, anything with moving parts in seawater is a nightmare as far as I can tell.
That would mean we’d be well into the type 1 civilisation about 10^19W a year and we’ll be on the way to a type 2 civilisation.
There may be some neat tricks, this is an area I know I'm not good at, but you have to be very careful.
SF authors (like David Brin) have screwed up on this very topic.
Lasers can be used for cooling, by shining a laser on a target carefully set up so that anti-Stokes scattering carries away entropy. The light scattered is quite incoherent, though.
Not really, no. Even if you completely solved the issue of corrosion (which we absolutely haven't), you'd still have to deal with biofouling - anything you leave underwater will rapidly become covered in algae, seaweed and invertebrates. We have antifouling coatings, but a) they're quite toxic, for obvious reasons and b) they need to be regularly renewed.
That would be enough of a problem, but you've also got the cost and difficulty of maintaining underwater infrastructure. It's inherently dangerous, very slow and often made impossible by tidal or weather conditions.
Offshore wind turbines are already much more expensive to build and maintain than onshore, but tidal generators are on another level entirely.
There was a project to build a tidal lagoon in Cardiff [1] that was eventually abandoned, and I don't know about the environmental impact. But it had the merit of being ambitious.
It's more useful for getting from 90%/95% to 100% green energy than from 0% - 90% though, and it's more expensive than natural gas performing the same function so we likely won't see it used in anger for a while.
Where did you get that idea? Hydrogen is extremely hard to work with and really really wants to escape from any containment vessel you put it in. See https://www.sciencedirect.com/science/article/pii/S136403212...
Your article talks about it positively.
He said it wasn't unusual to have gales in the winter, with >100Km/hr winds.
Seems to be a rich local resource.
Despite multi-decade mismanagement by government
I disagree. Exactly this post shows much much progress the UK has made. Can you share some specifics of "multi-decade mismanagement by government"? Can you compare that to other highly developed countries? especially now Scottish Independence is receding from the conversation
Can you explain why this matters? I assume the UK minus Scotland has enough onshore and offshore locations to fully power itself with wind and solar.UK response to GFC was amongst harshest austerity policies in Europe, leading to infrastructure neglect, local government bankruptcy, degrading of the military and lack of investment in education, healthcare and the rest. This set the scene for Brexit, a policy which increased trade friction with the country's most important trade partners whilst also _increasing_ the immigration it was supposed to reduce.
- Scotland Independence
Indy movement argument for economic viability was access to wind / wave energy around the cost of Scotland. Over half of UK total wind energy comes from Scotland.
Yeah a long way to go but considering we are only really at the beginning of the green energy revolution this is all great news. It affirms that we can do it.
Before: Jan 600kWh electricity, 3300kWh gas = 3900kWh
After: Jan 1580 kWh electricity, 20kWh gas (cooking hob)
So in total, 41% of previous amount, and for heating, 30%.
So yes, for crappy uk houses heat pumps are totally fine.
Adding in solar pv, and a time shifting battery, and the bills are maybe £2k per year lower than they would be.
Past year average: £97.90/MWh Right now: £5.99/MWh.
Better transmission and storage tech or better ways to scale demand at different times will be a game changer here.

TLDR It is a superior long duration liquid energy storage system vs hydrogen.
Hydrogen is cheap for long term storage because underground storage caverns can be extremely cheap (solution mined in salt formations), less than $1 per kWh of storage capacity. This is how natural gas is often stored, after all. There are alternative e-fuels but they have various problems. Ammonia is touted a bit below this comment in these responses.
I was thinking low cost retail electricity would be quickly absorbed by anyone not yet on electric (or district) heating buying cheap electric heaters (and they ARE cheap).
My opinion if you get regular periods where electricity prices drop to zero or negative someones going to move to take advantage of that.

National Grid don't want these storage projects to allow us to tide over for days of no wind / no solar, but to add grid balancing.
At the moment if a large power supplier disconnects (e.g. a 1.2GW Nuclear plant) then to handle the drop in supplied power over a period of seconds/minutes before a standby gas turbine generator can fire up they currently rely on the "spinning" mass within the system - literally the intertia of the spinning steel within all the remaining nuclear, gas, coal, biomass power plants. As the grid is being decarbonised this spinning mass is being reduced (Unfortunately wind turbines don't have enough mass for this) and they need to add more responsive balancing.
Grid scale storage on the order of days isn't really viable yet.
In the not so distant future I think we will see a lot of sharply negative pricing on windy days, given that we will probably have ~70GW of wind capacity installed for perhaps 50GW of demand by 2030.
Then on non windy days (especially at night with no solar), somewhat higher prices - not sure how high but there is going to be a big delta between the two.
That means there will be a lot of aribitrage to be had and money to be made to store and shift that power.
My guess is H2 will work quite well for this, as even if it's really quite inefficient the fact your input power is free/negative negates a lot of that. It really will come down to how cheap hydrogen electrolyzers can get.
My ev has 100kWh, just the bi directional is not yet working
Only if you actually believe my Batterie has only 1000 cycles.
You can easily charge and discharge EV Batteries a lot more times if you do it slow and controlled. 1000 also only means reduction of load to 80% (in theory/worst case).
And no i'm not doing this for $2, i would assume that i would consume 50kWh per day for heating, which is already nearly $20 and its about grid stability.
Flywheel storage (which is not new), but we sacrifice some efficiency and energy density so we can do it for cheap.

The forecast is to beat the record peak 4610MW for wind today too.
Seems the links to/from rest of europe are working out fairly well. Is there some web source that would show the "trade balance" on eg monthly basis?
Since then Germany has increases it’s own LNG capability and gas storage in Europe was filled much sooner
I believe there might be a lot of wind power, but the UK grid doesn't yet have the capacity to transfer it, with London and the SE being a key user of power. Until then a proportion of wind power needs to be curtained, and gas power generated near the South East.
A coming link from Scotland to Norway should allow power to be exported, in addition to the England Norway link.
The main issue I believe is the Scotland to England link, a second interconnect, this time on the Eastern side of the British isles is being built.
Batteries can only soak up only so much extra wind power, and currently there isn't much call for desalination plants in Glasgow.
Checking Octopus it seems to be averaging about £140 a month on my account.
Look further at the 'past day' stats on that page, 61% of power came from wind in the past 24 hours and 78.5% from 'zero carbon' sources overall (also including hydro and nuclear). This is fantastic progress.
Like a heat dome, for example, is only possible when there’s no wind to push the dome away.
Oh wait.
