Wind and solar capacity additions?

This model calculates how large global wind and solar additions would need to be, in GW per year, to deliver our roadmap to ‘net zero’.

Annual capacity additions need to treble, we find. This is an enormous scale-up, which likely also entails a trebling of global wind and solar spending.

The model is disaggregated region-by-region, and dovetails with our other models of decarbonizing the US, China, and broader gas-and-power use in Europe. 85% of the capacity growth must also take place outside of Europe and the US.

Please download the model in order to stress test the rate of capacity additions by region, renewables’ decline rates, asset lives and the grid shares.
