40% for the first time since the 1940s

Ember Energy’s Global Electricity Review 2025 made for fascinating reading. 3 takeaways –

  • Clean power passes 40% of global electricity for the first time since the 1940s. This is amazing to see because we are only getting more electricity hungry as a society.
  • Solar doubled in three years – nearly half of the boom came from China
  • The growth in fossil fuels came because of hotter temperatures and more cooling needs.

It is fascinating to reflect on the self-perpetuating nature of choices.

Hotter temperatures force more cooling and more carbon for peak loads. The more we use carbon, the hotter the temperatures get, and so on.

I’m hopeful we’ll see this graph go to 60% clean electricity by 2030 – powered by solar. The business case is as simple as it gets – cheap energy from the sun. And this exponential growth makes me optimistic that the picture will look a lot better in a decade.
