While nuclear energy is regarded as the lesser of the two evils when compared at an emission level to the burning of fossil - fuels, it may trump on the containment of the heat process, which burns in a contained nuclear reactor through an in - ward heat - chemical reaction called fission, but nuclear energy production is a chain from uranium mining to the toxic waste disposal and therefore as an entire process is an equally high risk environmental option.

Fusion remains the holy grail of clean energy research, because the fusion reaction generates new elements that are not radioactive, unlike nuclear fission which leaves us with hazardous fuel wastes that require generations of management.
