I assume you mean "nuclear" energy. Nuclear power is considered beneficial for several key reasons — especially for fighting climate change and supplying reliable power. Briefly:

Main advantages
- Very low greenhouse‑gas emissions in operation: nuclear plants emit only a few grams of CO2 per kWh over their lifecycle, roughly comparable to wind and much lower than coal, oil or natural gas. That makes nuclear useful for decarbonizing electricity.
- Very high energy density: a small amount of nuclear fuel produces a huge amount of energy, so fuel needs and mined material are far lower than for fossil fuels.
- Reliable, dispatchable baseload power: nuclear plants run at high capacity factors (typically ~80–95%), providing steady, predictable generation that complements intermittent renewables (wind/solar).
- Small footprint for the energy produced: compared with renewables that need large areas (wind/solar) or the pollution from fossil fuels, nuclear requires less land per unit energy.
- Long operating lives: reactors can operate for decades with proper maintenance and upgrades.
- Reduced air pollution and public‑health impacts: replacing coal and gas with nuclear reduces particulate and NOx/SOx emissions, which lowers morbidity and mortality.
- Advances in technology: new designs (small modular reactors, Generation IV concepts, passive safety systems) promise enhanced safety, lower costs at scale, and better waste and proliferation characteristics.
- Useful byproducts: nuclear programs produce medical isotopes and other industrial materials.

Main caveats and challenges
- Radioactive waste: spent fuel is small in volume but long‑lived. Solutions include secure interim storage, deep geological repositories (being implemented in some countries), and recycling/reprocessing in some programs.
- High upfront capital cost and long construction times: building large reactors requires big investment and long lead times; cost overruns are common in some markets.
- Safety and accident risk: major accidents are rare but have serious consequences and shape public opinion. Modern designs and strong regulation have markedly improved safety.
- Proliferation concerns: some fuel cycles and technologies can increase risks of diversion for weapons unless tightly controlled.
- Regulatory, political and social acceptance: public opposition or policy shifts can stall projects.

Bottom line
Nuclear energy is a low‑carbon, high‑reliability way to produce large amounts of electricity and can play an important role in deep decarbonization when paired with renewables, energy storage, and strong safety/regulatory frameworks. Whether it’s the right choice depends on local priorities, costs, and policy. If you want, I can compare nuclear to wind/solar/costs in your country or explain small modular reactors, waste storage options, or safety records in more detail.
