Answer:
Nuclear is reliable.
Nuclear plants are the most efficient source of electricity, operating 24/7 at a more than 93 percent average capacity factor. ... That's more than two times the capacity factor of any other carbon-free source. During the 2019 polar vortex, U.S. plants operated at more than 98 percent capacity.
On the other hand, Wind is not as effective as some countries have little to no wind, especially the hot arab or african countries.
Some disadvantages are:
The wind is inconsistent.
Wind turbines involve high upfront capital investment.
Wind turbines have a visual impact.
May reduce the local bird population.
Wind turbines are prone to noise disturbances.
Installation can take up a significant portion of land.
Wind turbines can be a safety hazard.
Nuclear:
Expensive to Build. Despite being relatively inexpensive to operate, nuclear power plants are incredibly expensive to build—and the cost keeps rising.
Accidents.
Produces Radioactive Waste.
Impact on the Environment.
Security Threat.
Limited Fuel Supply.
However, both are at least better than fossil fuels as they are renewable.
