  • Nuclear fusion energy has the potential to revolutionize future power supplies by offering a limitless supply of clean, green, and warming energy. This process, which produces more energy than it uses, is what the sun has been doing for billions of years. Scientists have been working on replicating this process for about 70 years and have finally achieved a significant breakthrough. However, it may take a few decades before this technology translates into energy for homes and businesses.The rising cost of energy and the environmental impact of consuming fossil fuels have prompted the search for alternative sources. This California lab may have found the answer with their significant milestone in nuclear fusion research. This breakthrough brings us one step closer to achieving zero-carbon, abundant fusion energy that could power our society sustainably.In the UK, three quarters of the energy consumed comes from fossil fuels, thus reducing this dependency is crucial for meeting climate goals. Nuclear fusion offers a promising alternative. Scientists have successfully recreated the fusion process on Earth using powerful lasers. By focusing these lasers on atoms, they can fuse them together to release energy. For the first time, they have managed to produce more energy than was put into the process.Compared to current nuclear plants that rely on fission, which emits harmful radiation along with energy, nuclear fusion is a cleaner and safer option. While there are still challenges to overcome and more research to be done, this breakthrough provides hope for a future powered by clean and abundant energy.
  • Subtitles section
  • Good evening.
  • Imagine on this coldest of nights a limitless supply of clean, green, warming energy.
  • It sounds like a physicist's dream.
  • Actually, like an energy bill payers too and an environmentalist for that matter.
  • Nuclear fusion is a process which produces more energy than it uses.
  • In fact, it is what the sun has been doing for four billion years.
  • Scientists have been working on replicating it for slightly less time, about 70 years, and finally have succeeded.
  • It is a serious, serious breakthrough, pretty much everyone agrees.
  • But don't turn the thermostat back on just yet.
  • It may not translate into energy for homes and businesses for a few decades.
  • Still, it isn't every day someone discovers a holy grail.
  • This year, more than ever, the cost of energy has been on all of our minds.
  • The political and economic price of relying on gas from countries like Russia and the environmental impact of consuming fossil fuels.
  • But could a scientific breakthrough at this California lab provide the answer?
  • This laser, the key to a sustainable future?
  • This milestone moves us one significant step closer to the possibility of zero carbon, abundant fusion energy, powering our society.
  • In the UK, three quarters of the energy we consume comes from fossil fuels.
  • Bringing that down is key to meeting our climate goals.
  • So it's hoped this breakthrough could provide an alternative.
  • Nuclear fusion is what keeps the sun burning.
  • Scientists have recreated that on Earth using powerful lasers.
  • They focus them on atoms, fusing them together to release energy.
  • Now, for the first time, they've managed to produce more energy than was put in.
  • It's cleaner than current nuclear plants that rely on a process called fission, which emits lots of energy but also harmful radiation.
  • So this facility is very similar to the National Ignition Facility in the US. Physicists here in the UK have spent decades developing the science.
  • So here at the Central Laser Facility in Oxfordshire, there's much excitement.
  • We've reached what people call the holy grail of nuclear fusion research, which is to get more energy out than what you put in.
  • It can create a clean, essentially zero radioactivity infinite, secure energy source.
  • So if you can do all those things in an economically viable way, then it really is the ultimate energy source.
  • This huge laser, the size of two Olympic swimming pools, is similar to the one used in the US experiment.
  • The laser pulses travel along here and into these portholes.
  • At its target, it's the equivalent intensity of all the sun's light hitting the earth, focused down onto the head of a pin.
  • There's still a long way to go until this scales up.
  • Scientists now calling for more investment so we can harness this power to protect our planet.
  • And Rebecca is here to talk about all this.
  • So you've got one minute to explain the secrets of the universe and the meaning of life.
  • No, that's not a sensible question.
  • I guess this is exciting.
  • I mean, look, there's been a lot of bad news around, hasn't there?
  • And here there is something to be quite joyful about.
  • But when are we going to see it on the grid, realistically?
  • Well, it's hard not to feel excited.
  • It is a huge achievement.
  • But the joke among scientists has always been that fusion is the future and always will be.
  • Even the optimistics say it could be decades before we turn this into a realistic power source.
  • To put it into context, this experiment produced the equivalent energy of two Mars bars.
  • So we're a long way off powering our homes.
  • It took $8 billion of investment to get this far, and it'll take much more to progress this.
  • Others point out that this is already too late for the climate crisis, and we should be investing in existing low-carbon technologies like renewables to ensure we have both short and long-term strategies.
