Paragraph 1

There has been a relentless to find sustainable energy 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 have tried to replicate this . Scientists in the USA say they recreated the of the Sun for a minuscule fraction of a second. Powerful lasers blasted a target to create a reaction. The burst lasted just 100 trillionths of a second, but it created 10 quadrillion watts of . Ten quadrillion is equal to 1 followed by 16 zeros. The power the created is the equivalent of 6 per cent of all the from the Sun hitting Earth's surface at any given .

Now go to   Paragraph 2.
