At the end of 2020, solar PV and wind each had nearly twice the global installed capacity (Gigawatts, GW) of nuclear.

Importantly, the deployment rate of new solar and wind capacity is much larger than for nuclear, and so the gap is rapidly widening. Over the past 5 years, the growth in installed nuclear capacity was only 11 GW compared with for 417 GW for solar and 266 GW for wind. Compared with solar and wind, nuclear power station construction is a cottage industry.

 

The combined global annual energy production of solar and wind (Terawatt-hours, TWh) has passed that of nuclear. Because solar and wind capacity is growing much faster than nuclear capacity, this gap will rapidly widen.

This is just the begining. As more utilities add battery storage it will grow even faster. The cost is much lower. There is no pollution or water use. Nothing else has improved so much and dropped in cost as well. Combines with hydro and Geo-Thermal it is as perfect as we can get.

Large-scale low-cost energy storage isn't batteries; rather, its off-river pumped hydro: https://energycentral.com/c/pip/millions-gigawatt-hours-cheap-energy-sto...
