Fusion is the fundamental energy source of the universe. It is the process that powers the sun and the stars. In a fusion reaction, energy is released when the nuclei of two light atoms (such as hydrogen) fuse together to form a heavier one. Tapping into this energy source offers the prospect of a long-term, safe, environmentally friendly option to meet the energy needs of a growing world population.

Fusion is an environmentally friendly energy option offering the possibility of a sustainable, large-scale and long-term energy supply. Several factors make it particularly attractive for large-scale, base-load electricity production:
