It's funny how photography changes the way you see everyday places. I’ve somehow ended up with favourite staircases on the Underground, yes, staircases!

This one at Forest Hill is definitely one of my favourites on the Overground.

The ISS edition of my experiments visualising energy data using Blender.

It shows most major high-voltage transmission lines, inter-connectors, power stations, wind farms, solar farms and more.

Colours show line voltage if available, and only power lines above 132 kV are visible unless they are offshore.

Data from OpenStreetMap and Mapterhorn.

If we break it down by individual technology, I estimate that in 2026 solar will be 10% of global electricity generation, wind 9%, and other renewables 2.5%.

One caveat: these plots only cover electricity, and there is lots of non-electric fossil fuel use (e.g. for heat)!

Non-hydro renewables (primarily wind and solar) are on track to pass gas this year as the second largest source of electricity generation globally. The rapid over the past 10 years is pretty remarkable!
