Some countries have an almost 100% renewable electricity mix thanks to favorable geographical conditions, but this is difficult to generalize and apply elsewhere. Intermittent renewable energies do not guarantee stable production, requiring the addition of controllable means of production to the mix.
Nuclear energy is an intermittent source of electricity
False
Unlike renewables such as solar and wind, nuclear power plants can operate continuously, providing stable and predictable electricity generation. Reactor shutdowns are events that occur several times a year and cause nuclear production to vary, but this is nothing like the intermittence experienced by wind turbines and photovoltaic panels.
