Fusion power is distinctly different from fission power in that it produces little radioactive waste, some physicists even predict that we may have this technology by 2030. Other than being a tremendous source of potential electrical power, nuclear fusion power may also perhaps solve our energy needs for this century.
It is then clear that nuclear fusion based power would be the holy grail for which our problems with regards to energy needs would be largely solved due to that fact that it could potentially generate huge amounts of power. The fact remains that we are not there yet, in fact it was only in August 2013 that the NIF (National Ignition Facility, which is located in California in the United States) was able to generate fusion power with a net energy gain. Actual controlled releases of fusion power were first made in 1991 in England.
There also needs to be a dose of skepticism with regards to achieving full fusion power capabilities. In 1951, Argentinian President Juan Peron, claimed that Argentina had successfully harnessed the power of the sun with the help of German scientist Ronald Richter. His claim turned out to be fake, however.
Fusion power thus offers a lot of promise, but in terms of actual power output we have only recently been able to harness it with a small net energy gain. The next 10-20 years will therefore be critical in determining whether we can generate this source of power on a massive scale.
