There's so many exciting projects[1] going on in Europe in this space. The offshore Danish wind power island and the massive wind farms off the UK coast for example. Given how windy[2] the coastlines around Britain and Ireland are, it's great to see this in development.

One project I'd like to see get implemented is connecting Iceland to Britain to give 24/7 renewable baseload energy via undersea cables to Britain and potentially to mainland Europe. This would reduce the need for so many battery capacity being built out[3].

[3] makes me wonder if we could simply convert Iceland to a giant geothermal power plant, and power most of Europe..

Sure, it would take some investment, but isn't the technology already here?

The Swiss tried geothermal power at large scale but the initial tests caused two earthquakes of 3.5 and 3.4 respectively. They then stopped the project.

Maybe somebody else has examples of well running geothermal power plants but at least the Swiss are quite vary of them.

Iceland does lots of geothermal power.. indeed power intensive industries like aluminum refining favor Iceland due to low power cost.

Sure, it's hard to know how far geothermal in Iceland could scale..

But there is an active volcano, how much worse can it get? :)

That’s what I often think. We have the technology. Sure it will take some time to iron out the kinks and there will be transmission losses but we can do this with current technology.

Despite all the recent talk the real barriers are lack of political will and investment, it was viewed as an emergency we could pull it off very quickly indeed.

And what a juicy military target those undersea power cables would be in such a situation (Unfortunately)

That'd be quite the underwater cable. It'd span about 900 km to get to the Scottish mainland:

1050 km to reach the tip of Norway (or Ireland).

So what? Use the https://en.wikipedia.org/wiki/Faroe_Islands as junction, and branch from there to Scotland and Norway.

Each branch wouldn't be that different in distance from the part between Cyprus and Crete from the https://en.wikipedia.org/wiki/EuroAsia_Interconnector or the related https://en.wikipedia.org/wiki/EuroAfrica_Interconnector
