In 2020, nuclear is still the second-largest source of low-carbon electricity, after hydropower. In the US, Europe and Japan nuclear power is the largest source of low-carbon electricity generation. It provides more than hydropower, but also more than wind and solar PV combined. Nuclear energy has reduced global CO2 emissions over the last 60 years by almost 20%.

France has proven that using 80% nuclear energy for electricity built in the 1980s was a faster and cheaper way to decarbonize than Germany construction of solar and wind power. France is still doing better with nuclear than any other country has done with wind and solar.

China is also building solar, wind and creating a massive advanced energy grid using ultra high voltage power lines to reduce energy losses for transmitting over large distances.

We will be able to compare states, regions and countries that attempt to only use solar, wind and batteries with other countries that use solar, wind, batteries and nuclear power. We will see which countries have problems with power outages and which get less energy generation for the costs spent on infrastructure.
