Fusion will be environmentally sound without atmospheric pollutants or contribution to global warming. It will be economically attractive and capable of producing the energy that future generations will require. The sun and stars are powered by fusion. Harnessing these reactions to produce energy on earth presents a grand challenge to scientists and engineers. Steady progress has been made but several scientific and technological advances are necessary before the dream of commercial electricity production will become a reality.
Fusion reactions release enormous amounts of energy.
