JET research reactor: European project reports “world record” in nuclear fusion. 69 megajoules of energy were produced from 0.2 milligrams of fuel.
This could run a television, a kettle or an electric stove for several hours. Fusing atomic nuclei could be an efficient, safe and environmentally friendly source of energy. It would be a tool in the fight against the climate crisis, which is also why politicians and scientists have a lot of hope in the method.
