For the first time ever, scientists successfully produced more energy from a nuclear fusion experiment than the laser energy used to power it.

In the infographic below, Visual Capitalist's Mark Belan and Bruno Venditti describe nuclear fusion and illustrate how this discovery may pave the future for a new form of clean and sustainable energy.

What is Nuclear Fusion?

Nuclear fusion powers the Sun and the stars, where immense forces compress and heat hydrogen plasma to about 100 million degrees Celsius. At this temperature, the lighter particles fuse into helium, releasing enormous amounts of energy.

Nuclear fusion is a fairly clean energy source as it does not produce harmful atmospheric emissions and only produces a small amount of short-lived radioactive waste.

Scientists have been trying to replicate it on Earth for almost 70 years, using isotopes of hydrogen—deuterium and tritium—to power fusion plants.
