I get irrationally angry when a map is skewed in this way and there is no way to change it. The more you zoom in, the worse the distortion is made to be. Even zooming all the way out does not eliminate the angular distortion. This took actual effort on some programmer's part! Who ever thought that this is a good idea?!?

It's like those navigational mini maps (car or computer game) that won't keep north pointing up... only worse.

Also got annoyed by this, but worked out pretty quickly that if you hold down right click and drag then you can change the angle

Something I've wondered for a while: if the whole continent is on a synchronized grid, how can countries tell to or from whom they're exporting and importing electricity. I can see how they can measure their total imports or exports by comparing generation to consumption, but how do they figure out which neighbour they're getting electricity from / sending it to?

There are five synchronous areas in Europe, the largest one being the synchronous grid of continental Europe [1].

Each national grids has interconnections with other grids and you can measure the flow of power through these interconnections to know who is sending electricity or getting electricity from neighbours.

You can measure the flow of power by calculating the vector product of the current and voltage in the power line. EEVblog has a very good explanation video how this is done in an (analog) domestic watt-hour meter: https://www.youtube.com/watch?v=P_3DXcB9-xE

For completeness - that's just one grid included in this viz, for the map of the different european grids see: https://en.wikipedia.org/wiki/Synchronous_grid_of_Continenta...

(Russia is another big chunk of Europe but not included in the above map, though I think it may be the same grid with the Baltics)

For the question, measuring the flow of electricity is just normal power engineering, your home electricity meter does it as well. It's not so much the countries doing it though.

One observation I could make from the visualization is that major cities have very big power generation centers, despite that they seem to be drawing power from surrounding areas. It is very apparent near London. I guess it is obvious that bigger cities have more demand from both industrial and residential consumption.

When looking at France, at a zoom level where one can see the whole country, all the green dots are located next to nuclear power plants. It's a good reminder that the french grid is mostly powered by nuclear. It'd be nice to see the same map over summer to see if the different electric mix then gives birth to a different map.

if it wasn't for France having primarily used nuclear power decades ago, Europe as a whole would be in a much much worse state when it comes to CO2 emissions. That makes it abundantly clear that nuclear needs to be a part of the mix when it comes to non-emission generating energy production.

Not sure if that still holds true nowadays with renewable energy and storage having got cheaper and cheaper.

Earlier quoted context omitted.

France has 12% of Europe's population, and its primary energy is 45% from fossil fuels and 40% from nuclear power. The effect on Europe as a whole is therefore pretty small.

France is simultaneously one of the most populated countries in the EU and the of the top transitioned countries, it does make a difference
