Unkel I think you are being too optimistic and you detractors are being too pessimistic. Turlough Hill only has a capacity of 292MW but it can go from standstill to full generation within 13 seconds and can generate electricity at full load for up to six hours per day.
The average difference between the peak load and min load every day is about 2000MW but fortunately the peak is during the day when the sun is shining - except in December/January
. Also we often get 24-48 hours of very low wind power generation.
The cost of going renewable increases super-linearly as we approach 100% renewable. Something like 85% renewable can be had relatively cheaply and quickly. But even this would require a combination of more reneables, more storage and more interconnectors. It would also help if we could make the heavier consumers smart so they take advantage of lower rates at times of high renewable generation.0 -

I was not being optimistic, I was just explaining the idea about the plan. It's very doable from an engineering and cost point of view, but it will mean flooding some very large areas of land and that will never get political support in Ireland, hence why I referred to having a friendly dictator

Anyone know enough German to know what’s going on here? They have an ID.3, e-Niro, Taycan and Ampera using Superchargers.

There’s a friendly dictator in Turkey and he has just flooded 12,000 years of history in Hasankeyf.0 -

dam damnThanks
.
That thing generates about 4 times what we use at any given time. However, the flooded area is equal with the sum of the first 8 largest Irish lakes or something like this Still wishing Aladeen to build it?0 -

I think if that was the place flooded, you'd have a majority of pop. behind it no matter the cost 0 -

That area does a pretty good job of flooding itself regularly anyway, might as well get some use out of it "The internet never fails to misremember" - Sebastian Ruiz, aka Frost

So what you're saying is that we'd only need 1/4 of that area, and we already have a bunch of lakes we can use anyway "The internet never fails to misremember" - Sebastian Ruiz, aka Frost

The BMW I3 seems to fare badly on that model check tool. Worse than the same year Leaf?
In fact, if you choose 2017, giving 3 years of data, the I3 is by far the worst of the cars available here.
Cue Mad_lad to regale us with tales of his zero degradation i3! 0 -

I wonder where that data is from? Must be US only. And where did they get it from? The fact that they only have i3 info from 2017 doesn't give me a lot of confidence , the car has been around since 2013. Also Tesla Model S only available from 2015 (around since 2012)
And a Nissan Leaf from 2012 has zero battery degradation? Yeah right
I'm calling BS on that study My ads on adverts.ie

No just some random thoughts. I was trying to visualize the size of things. Not really my field but I believe having the lakes is not enough. You need the heights to increase the potential energy.cruisey1987 wrote: »So what you're saying is that we'd only need 1/4 of that area, and we already have a bunch of lakes we can use anyway
Interesting enough Europe does not have large capacity hydro power units, largest was built by two dictators back in 70's.0 -

That's right. Hence the west of Ireland where you could have the lakes with quite some elevation above sea levelInteresting enough Europe does not have large capacity hydro power units, largest was built by two dictators back in 70's.
It upsets a few people who have to move house as their homes will be flooded. They will protest. A dictator generally doesn't really care and just makes the protest disappear My ads on adverts.ie

Discharge rates:
Three Gorges Dam: 48,800 cubic metres per second
River Shannon: 200 cubic metres per second.
https://en.wikipedia.org/wiki/River_Shannon
Apart from being Ireland's longest river, the Shannon is also, by far, Ireland's largest river by flow. It has a long term average flow rate of 208.1 m3/s (7,350 cu ft/s) (at Limerick)
https://www.aljazeera.com/news/2020/08/water-china-gorges-dam-nears-maximum-levels-200821044024067.html
With 75,000 cubic metres per second of water flowing in from the Yangtze River on Thursday, the reservoir's depth had reached 165.6 metres (543 feet) by Friday morning, up more than two metres (6.6 feet) overnight and almost 20 metres (65.6 feet) higher than the official warning level.
The maximum designed depth of China's largest reservoir is 175 metres (574 feet).
Authorities raised the discharge volume to a record 48,800 cubic metres per second on Thursday to try and lower water levels

With our annual rainfall & given the Shannon drains 20% of Ireland, we'd need 250 times the area of Ireland, or, 250 times our annual rainfall, to feed that dam.
We're not feeding that dam from a river or from rain My ads on adverts.ie

Guy buys a $31,000 electric "supercar" from a Chinese dealer, gets scammed with this!
All jokes about Chinese quality control are valid
They couldn't even get forward and reverse the right way round! 0 -
