From this map you might think that the UK is currently depending (96.5%) on fossil fuels. But it's not quite that bad: https://grid.iamkate.com/

The real eye-opener (for me) on the latter display is the emissions per kwh over all time - dropped steadily from 500g in (only!) 2012 to a steady 150g or so recently. Encouraging!

This is a good point – I'm not currently accounting for solar in the aggregate and I'm lumping everything else as "non-renewable" which is true but not ideal as it's not all fossil fuels.

I'm going to look at how to be a little more accurate with this, similar to Kate's great website.

I think hydro and tidal power is renewable right?

Sure is! I'm limited by the way the generation is broken down in the source data [1] as it doesn't make any distinction for tidal generation – though I'd argue that's probably a very small amount in the UK. Hydro is already separated though.
