This is a big deal⚡️Scientists around the world have been working on nuclear fusion for almost a century, and this week, for the first time ever, US scientists produced more energy than they put in, using powerful lasers. This “net energy gain” is a major milestone on the path towards a long-held dream of safe, emissions-free power, generated by replicating conditions only found in the sun and other stars. So how far away is a future powered by clean, green fusion? Well, nobody really knows yet. Major hurdles like scalability and cost remain, and they could take decades to overcome. This breakthrough however has captured the world’s collective imagination about what the future of energy could look like and put a spotlight back on renewable sources. Climate scientists and policymakers are hoping it will reignite conversations about our currently available technologies, like solar and wind, which many believe are the key to reaching emissions targets.
