Solar PV and wind
Arguably, the fastest change in global energy systems in history is underway. In 2020, new solar photovoltaics (PV) and wind capacity comprised 75% of global net new generation capacity (Figure 1) according to the International Renewable Energy Agency.
New PV and wind capacity was 10 times larger than net new hydro and coal capacity and 100 times larger than net new nuclear, carbon capture & storage, bioenergy, geothermal, solar thermal and ocean energy generation capacity.
Extravagant deployment growth rates are required for other low-emission technologies to catch PV and wind.
