> Norway can buy wind energy from the UK

Even Southern England cannot get enough wind energy from Scotland to fully utilise wind farms because transmission capacity is insufficient. I would imagine a transmission line to Norway will be even more expensive than to England.

But they are building such a link, because it'll make/save more money than it costs.

Imagine how many doom and gloom headlines we'd have avoided if these two massive construction projects could have been sync'd up perfectly or if we had a national press that could do anything other than try to scare people with big numbers.

The interconnects already exists.
