There has been a relentless quest to find sustainable energy sources in the past decades. One source of energy that has thus far eluded scientists is nuclear fusion. This is the Holy Grail of clean energy. Generations of physicists have tried to replicate this reaction. Scientists in the USA say they recreated the power of the Sun for a minuscule fraction of a second. 

Nuclear fusion is the best source of energy.

There has been no scientists replicating this reaction.

Powerful lasers blasted a tiny target to create a reaction. The burst lasted just 100 trillionths of a second, but it created 10 quadrillion watts of power. Ten quadrillion is equal to 1 followed by 16 zeros. The power the scientists created is the equivalent of 6 per cent of all the energy from the Sun hitting Earth's surface at any given moment.

The blast created 100 million watts of power.

Lasers need to fire through a large target.

Scientists do not know the power of the energy form.

This reaction equates to six percent of Sun's earth hitting energy.

Nuclear fusion powers the Sun and other stars. The website cnet.com said it is "a long-sought-after panacea for many energy and environmental challenges". Nuclear fusion power plants could solve our clean energy conundrum and provide infinite, safe, clean and green power.

Nuclear fusion could quite possible solve numerous energy difficulties.

Nuclear fusion would cause further struggles between the power struggles.

The Earth has no energy or environmental difficulties.

It could also reverse the damage we do to the environment. Physicist Dr Debbie Callahan, who worked on the experiment, spoke about the breakthrough. She said it is a "huge advance for fusion" and a big step toward generating "a net-positive amount of energy".

The addition of nuclear fusion can increase environmental damage.

Physicist Dr. Debbie Callahan worked on the NASA space station.

Nuclear fusion has the capability to build a positive relationship between clean energy and our environment.

Nuclear fusion technology is not a breakthrough.

Futurism.com said: "The promise is as lucrative as it has ever been – an infinite supply of carbon-neutral energy without ever running the risk of a nuclear meltdown."

Carbon-neutral energy is the future of clean energy.

There is zero risk of nuclear energy damage.

Lucrative energy sources are of the past.

Dr. Debbie Callahan advises energy and a risk for nuclear meltdowns.
