Regional economic and industrial development policy can resolve inequity, and can mitigate risks posed by resistance from declining industries 59. Without any further energy policy changes, solar energy appears to follow a robust trajectory to become the future dominant power source before mid-century.
A low energy demand scenario for meeting the 1.5 °C target and sustainable development goals without negative emission technologies. Nat. Energy 3, 515–527 (2018). Victoria, M. et al. Solar photovoltaics is ready to power a sustainable future. Joule vol. 5 1041–1056 (Cell Press, 2021). Nemet, G.
Regarding global power generation, solar nearly doubled its share over the past 3 years, growing by 1.3 percentage points only last year to a 7% share in the world's electricity mix. This growth continued to drive renewable penetration and pushed additions of conventional electricity sources to a new low.
A solar-dominated future is likely to be metal and mineral-intensive 48. Future demand for “critical minerals” will increase on two fronts: electrification and batteries require large-scale raw materials – such as lithium and copper; niche materials, including tellurium, are instrumental for solar panels 49.
