It is easy to see that the German Energiewende takes Germany down into a bottomless green hole.
See http://wp.me/p1RKWc-11F
A European Energiewende will be even worse.
During the winter, when there is most demand for power, we have minimum sunshine. Nothing at nighttime.

Contrary to many Green Dreams, the North European wind is almost synchronized.
On http://www.reo.dk/CustomerData/Files/Folders/9-udgivelser-pdf/275_danish-and-european-energy-2015-iia.pdf you will find a very comprehensive evaluation of the North European wind.
On page 22 you will see (normalized) data from Austria, Belgium, Czech Rep., Denmark, Spain, France, Finland, Hungary, Poland, Sweden and Germany.
Over this enormous area, the wind power varies quite a lot.
Maximum 269 % of average and minimum 18 % of average (7 % of maximum)
The modern society cannot function without a stable supply of power.
Besides all this, it will be very expensive, if we should have wind-turbines here, there and everywhere – just hoping for something fantastic to turn up.

Norway has quite a lot of regulated hydro-power, but it will be a very expensive drip in the ocean if it should satisfy European needs.
In South-Australia, the heavy reliance on solar energy has made it necessary to introduce scheduled black-outs.
In Germany, it has not been necessary. They get help from Poland and especially from France.
And of course, there is intensive strip-mining and use of brown coal.

My conclusion is that whatever we get of connections with a strong international grid, it will never conjure a stable supply.
OK
Let us realize that nuclear is green energy and more reliable than the renewables.

To avoid mistakes, I mention that uranium can be extracted from see-water and there will be enough for quite a long time.
However, Neodymium, which is used in wind-turbines, is a rather scarce commodity.

On the last page of another site you will find a summary of win-data from 14 countries in North Europe.
The maksimum is 78 086 MW and the minimum is 3748 MW
It is less than 5 %
The obvious conclution is that you can not share what is not there.

Vinden er synkroniseret
Kan smart grid redde den fluktuerende vindkraft?
I diskussionen om vindkraftens variation nævnes ofte at man ‘sådan bare’ skal forbinde landene med et stærkt net af højspændingsledninger.
Problemet er behandlet af Sören Kjärsgaard, der giver en meget grundig vurdering af energisituationen, i Europa.

” Det er klart, at når du har sagt vindkraft, så må du også sige back-up.”
Kan denne back-up bestå af Europæisk vindkraft der er forbundet med et super smart grid?
På diagrammet på den sidste side fås en vurdering af den samlede vindkrafts variation i følgende lande:
D – GB – F – SP – SE – PL – DK – BE – FI – A – NL – HU – CZ – CH
I dette store landområde varierede vindenergien (2016) mellem
78 000 MW og 4 000 MW (5%)
Svaret vil blive NEJ – Desværre
Selv nok så meget smart grid kan ikke fremtrylle en stabil forsyning.
I Syd Australien hvor der ikke er gode forbindelser til norsk vandkraft og svensk atomkraft, der har man set det, vi ikke vil se i Europa – endnu.
Før man regnede på prisen ville man have tilstrækkeligt med batterier.
Nu har man travlt med at få dieselgeneratorer og gasturbiner.
Ikke nok med det, så vil man forbyde mere vindkraft.
Man kan nemt finde meget, men jeg vil nøjes med at referere til følgende.
