The U.S. Department of Energy is set to announce it has made a breakthrough on fusion energy.

By using lasers in an experiment, scientists have been able to create a ‘net energy gain’ from an experimental fusion reactor.

This would represent the first time that researchers have successfully produced more energy in a fusion reaction than was consumed during the process.

This is the same energy that the Sun and the Stars produce.

Nuclear fusion is considered by some scientists to be a potential energy of the future, particularly as it produces little waste and no greenhouse gases.
