I do bloody love this chart. Who'd have thought, 20 years ago, that solar would be ~10% of world electricity generation by 2024 - and over 20% in some countries, rising rapidly in others?

Definitely not me. When I started this job I hoped to be part of a solution for maybe 1% of global electricity.

A chart from https://docs.nrel.gov/docs/fy25osti/95135.pdf , sourced to the IEA as of April 2025, showing solar power as % of generation in different countries. This varies between over 25% for the Netherlands, through about 24% for Spain, about 14% EU average, about 8% for the US to almost nothing in Norway. Text says that the IEA reckons global is about 10%.

I thought we might see 15% of global electricity from renewables excluding hydro by the end of career. We passed that last year, but I'm not ready to retire any time soon.

  1. The things you see in your next decade of work could make the last few decades seem like slow motion if we do this right. I am not sure how anyone working in energy could retire now.

  2. One thing that I do miss from earlier in the transition is exciting epiphanies. It’s just felt like watching a pot boil for quite a while now. There’s so much that we still don’t know about what the full transition looks like, and life thereafter. Plenty left to do!
