Andrew Birch, a physicist and solar expert, has unveiled the S-Curve model, forecasting solar energy to meet over half of global demand by 2035. The model replaces outdated metrics by focusing on delivered energy, showing solar’s efficiency and electrification benefits. Solar’s cost reductions and accelerating growth are key drivers of this transition. Birch and Prof Andrew Crossland of Durham University highlight solar’s potential to lower costs, boost resilience, and cut emissions. The model predicts solar will surpass nuclear by 2025. It will overtake oil by 2031. By 2035, it could save $9 trillion annually. This depends on fair competition without fossil fuel subsidies or clean tech tariffs.
