That struck me as odd, because Denmark is flat as a pancake - it's basically an overgrown sandbank laid down by Norway's fjords. But the article explains that the cable will carry power from Norwegian hydro plants, which for some reason comes via Denmark. There is a direct cable from Norway to the UK, but i suppose this adds some redundancy, which is good. And, as the article notes, allows the UK to export surplus power (from wind?) to Denmark.
On Denmark being flat, here is its highest point - note that in the photo, the highest point isn't visible, because it's behind a barn:
Correct. Quite a bit of offshore wind potential Great Britain.

By going via Denmark the distance under water is shorter. Also continental Europe, mainly Germany and Benelux slurped the power first, so the infrastructures have already been there. Why not use them as much as possible, i guess? Although recently some direct point-to-point has been built.
That number doesn't say much, since the actual output will be a small percentage of that (15-20%).
Seven countries are expected to end the use of coal by 2025: Portugal (2021), France (2022), Slovakia (2023), the UK (2024), Ireland (2025) and Italy (2025) (per Europe Beyond Coal)
Politics and entrenched interests will have no choice but to accept market forces. The sun dumps enough power on the Earth in an hour to power all of humanity for a year, and it's mostly free for the taking.
