I really enjoy this one: https://app.electricitymaps.com/zone/GB

It shows energy sources for all of the countries in Europe on a map, import/export, prices and CO2 intensity.

The visualisation on that site is good, but it's sadly plauged with data errors. The UK data doesn't seem to correspond to any other source I can find. I think it might be delayed by 24 hours, but even that doesn't seem quite right...

A GitHub issue was filed regarding this: https://github.com/electricitymaps/electricitymaps-contrib/i...

Well, that issue explains a lot. The data source went missing, so the website just made up some data and used that instead!

That whole website is a nonsense, what's the point in visualising imaginary data and pretending it's real...

Totally agreed. May be the top link change to non-lying site so not to affect all the good works of others.

My favourite for showing UK grid data on a nice, clean, fast chart over custom timescales:

My favourite for showing many country's grids around the world, and the power flowing between them through interconnectors:

I love the data visualizations but I am always surprised to see so many different ones given how little use-cases they serve. They can broadly let people know where the power is coming for and help policy makers to a certain degree. They are just naturally interesting for a little bit while you explore but then drop off. It's almost like its most useful for exploratory data analysis and not a ton else

I'm curious if other people have interesting use cases here and how accurate is the data? Is this all people putting different layers on top of one source of truth for data - or patching together various sources?
