What happened
Ember data shows solar electricity generation narrowly overtook nuclear globally in 2025, and BBC analysis of the 12 months to September 2026 puts solar 13% ahead. Solar went from about 1% of world power a decade ago to a projected ~10% in 2026, met three-quarters of the growth in global electricity demand in 2025, and has grown roughly 2,700-fold since 2000 while nuclear output stayed flat. Jan Rosenow of the University of Oxford calls solar 'the engine of the power transition,' and Ember co-founder Dave Jones notes mainstream IEA outlooks assumed linear growth and slowly falling costs and 'got both wrong.'
Why it matters
For this audience the direct takeaway is thin: nothing in the text covers datacenter power, cloud pricing, or AI compute costs, so there is no concrete action for a builder here. The one transferable lesson is a forecasting one — the IEA's linear-growth, slowly-falling-cost assumptions missed solar by a wide margin, which is a reason to stress-test any linear capacity or cost projection you build into your own planning. Score reflects low relevance to shipping software, not the size of the energy story.
Discussion angle
The IEA got both the cost curve and the growth curve wrong by assuming linear change — where in your own infra or pricing forecasts are you assuming linear growth, and what would an exponential assumption break?
