It is commonly accepted that energy produced by the Sun is the result of nuclear fusion, a reaction in which two or more atomic nuclei collide at high speeds to produce a new type of atomic nucleus in addition to large amounts of energy. This process, theoretically, is an idea power source as it produces zero carbon emissions and resource waste during operation. In addition, it is highly energy efficient. It is for this reason that modern scientists are working to bring this solar source to Earth.
While nuclear fusion has already taken place in labs, reactions have yet to reach the point at which more energy is produced in fusion than is used to begin the process. A major breakthrough has, however, recently taken place. US researchers have recently been able to generate more energy in the fusion process than they put into the reaction in nuclear fuel. While the energy produced did not makeup for the energy that was also needed to start the reaction, this progress represented a major breakthrough in the quest for clean power.
