How does nuclear energy compare to other renewable energy sources?

The law of thermodynamics states that all energy is "non-renewable" because entropy is always increasing and that energy cannot be created or destroyed—it can only be changed in form. Nevertheless, when it comes to the energy sources that are currently available on Earth, we consider any sources that are directly derived from the sun to be "renewable." Examples of these sources include wave, water, wind, biomass conversion, and direct photo-voltaic electrical production. Nuclear power is generated from a fixed supply of raw materials that cannot be "renewed."

Even though the production of nuclear power is thought to be "cleaner" than that of "fossil fuels" (hydrocarbons), at least in terms of greenhouse gas generation, it still needs to use a finite mineral resource: uranium ores. These ores are not renewable, even though they may have very long lives, and they are only found in finite amounts on Earth.

Even though fusion power produces much more, it still uses more net physical resources and is generally cleaner for the environment than fission-produced power.

Nuclear energy is not classified as a renewable energy source, unlike solar, wind, and hydropower. While nuclear power has low carbon emissions, it generates radioactive waste and carries safety concerns. Renewables are considered cleaner and safer options, with advantages like sustainability, minimal environmental impact, and lower risks. However, they may face intermittency challenges, unlike nuclear power. The choice between them depends on specific factors like energy demand, geographical considerations, and environmental priorities.
