Nuclear energy supplies about 10% of the world’s electricity and nearly 20% in the U.S., with a capacity factor of over 90%, meaning plants run almost continuously—far higher than wind (35%) or solar (25%). It is also one of the lowest carbon-emitting sources, producing emissions comparable to wind across its life cycle. Modern reactor designs have advanced safety systems, and nuclear waste is tightly regulated and stored safely. With rising energy demand and the urgent need to cut emissions, expanding nuclear offers a proven, scalable solution for reliable clean power.
