There are exciting green stories unfolding all around the world as countries and communities build clean, cheap, and resilient energy systems at a staggering pace.

This session is looking at what the UK can learn from the places making the fastest progress, and asks how new tech is helping nations leave fossil fuels behind for good.

Meet the panel: who's on stage right now

• Lucy Siegle: An environmental writer and BBC broadcaster. She's interviewed everyone from David Attenborough to Björk.

• Li Wenxuan: Founder and CEO of PCG Power. He is a massive player in China's clean energy shift.

• Devon Cox: President of Pelican Energy TCI with two decades of utility leadership under his belt.

• Wade Crowfoot: California’s Secretary for Natural Resources. He manages an agency tasked with protecting the state's environment.

• Rachel Moriarty: Executive Director at Prince William’s Earthshot Prize. Her brief is to track down the world's most transformative environmental solutions and build the global partnerships needed to scale them up fast.

Hannah Fry brought up a staggering statistic in her chat with Jimmy Wales: if Wikipedia had simply run banner ads, the site could have been worth $10 billion.

So why walk away from that kind of cash? Isn't it annoying that you don't have a private jet, she asked. For Jimmy, the answer is simple. “It just made sense. This idea of neutrality is really important.”

Jimmy and Hannah touched on the future of the internet, the pitfalls of artificial intelligence, and his high-profile critics. Here are the biggest takeaways:

The problem with "plausible" AI

“AI tends to hallucinate and actually one of the problems hallucinations is they tend to be very plausible so if you go in and ask a question it will tell you something that sounds pretty authentic,” he said.

He shared a hilarious example of testing a bot by asking who his wife (Kate Garvey) married. The AI confidently claimed she married British politician Peter Mandelson. When Wales pointed out, “Isn’t he quite famously gay?”, the bot scolded him, stating it wasn’t appropriate to speculate about people’s personal sex lives!

Ultimately, Jimmy argued that AI desperately needs reliable data sources like Wikipedia to function well/ "Can you imagine what would an AI trained on Twitter be like? Very stupid you know, and very badly behaved."

The "Elon effect"

Hannah asked about Elon Musk's recent campaign against the platform, famously dubbing it "Woke-pedia."

Jimmy's response? A masterclass in unbothered success. “There was the day when Elon tweeted ‘defund Wikipedia’," Jimmy recalled. "We brought in about $5 million that day.”

Fighting for the dream of the internet

Despite the chaos of the modern web, Jimmy remains deeply optimistic about his life's work. He champions radical transparency in journalism and believes that, at our core, “The vast majority of people are basically good.”

His parting message was a rallying cry to preserve the collaborative, human-centric spirit of the early web:

“This is what the dream of the internet is really all about, and I just think we all of us have to really push and say, let's fight for the world where the things that matter are the things that we do”

OK, everyone suitably fed and watered? Let's look ahead to the next talk, which should be simply delicious. Hannah Fry, who has made a career out of explaining maths in a non-boring way (impressive), sits down with Jimmy Wales, the Wikipedia founder.

Jimmy, who says he's a "pathological optimist", argues that trust is the most important commodity we have in a world clouded by misinformation and nonsense. He and Hannah look at how this commodity is won and lost.

Wow I thought that was a really interesting panel. We often think of AI as a a uniformly bad thing as far as energy goes; I'd never really thought that perhaps it could help us to use LESS power by making everything more efficient. I liked a lot of Josh Parker's points, but the crux was: "There are so many opportunities for AI to help be a solution that goes well beyond its own footprint."

Thought-provoking stuff.

The next panel promises to be fascinating. It's all about the AI boom, which is incredibly power-hungry. The flip side is that it could pave the way to a smarter, greener energy system that uses less power. So is it a force for good after all?

Moderated by Sky News presenter Matt Barbet, this session brings together the heavyweights of tech and grid flexibility.

Meet the Panel

• Matt Barbet (Moderator): has spent over two decades anchoring flagship broadcasts and covering the world’s biggest stories.

• Maud Texier: Global VP of Data Centres and Industry at Octopus Energy. Maud has a ridiculously impressive CV, which is peppered with little names like Google and Tesla.

• Brian Denvir: Head of EMEA Energy Market Development at Google. Brian is working on Google's ambitious carbon-free data centre plan.

• Josh Parker: Head of Corporate Sustainability at NVIDIA, which makes the incredibly powerful chips that are driving the global AI revolution.

Ooh, Katie White just clapped back at Boris's claim that the government isn't doing enough to bring bills down. She says: "Boris says a lot of things - he might be on a different stage saying a different thing!"

She also said:

• "There has never been a better time to go electric"

• "We've reduced our emissions by 54% whilst growing our economy by 80%"

• "For economic and security reasons, renewables are the right path to take. It's just practical and sensible when you look at what our natural, most abundant resources are on this windy little island."

Boris "My advice for the new PM? Don't listen to anything Milliband says about energy"

During a wide-ranging and characteristically blunt address, Boris Johnson offered a whirlwind tour of his thoughts on national rivals, the UK's energy landscape, and the future of the planet.

He drew a laugh when he batted off questions about the Prime Minister's resignation with a single sentence: "My thoughts on Keir Starmer are entirely predictable." However, he did offer piece of advice for the newly empowered Labour party: "The government have got a huge majority, they should use it to do some sensible things for the country...the new guy shouldn't listen to anything Miliband says on energy."

And he did weigh in on Andy Burnham, who is widely expected to become the new PM. "Burnham? Doesn’t deserve the job at all, as far as I can see. He's going to get it (he hasn't been elected)."

Pivoting away from personal politics, Johnson struck a highly optimistic tone regarding the nation's infrastructure and resources. "The natural strengths of the UK are immense," he declared. "In sectors like energy, we lead the world."

To capitalise on that edge, he made a passionate case for upending the UK's current market structure in favour of regional rates. "I think it's mad that we have one energy price across the country," he argued. "I think there is a case for nodal pricing. Maybe the new guy, whoever it's going to be, will get it through."

He expanded on this idea, framing localized energy markets not just as an infrastructure shift, but as a core economic strategy:

“More renewables would be a wonderful thing for places like Lincolnshire, or Scotland, or Wales. You know, it's a great levelling up agenda. They happen to be the places where you can produce prodigious quantities of wind power, right, and that obviously produces some sort of some benefits for the local population. They might not necessarily like the look of all the wind turbines, or whatever, but then on the other side, they're going to have the cheapest juice in the country.”

Taking a broader, more philosophical view of the global transition, Johnson expressed total confidence in the viability of green tech. "Wind power and solar power can be more than adequate for the future of humanity," he noted. "I think the outlook is good."

Reflecting on the stabilizsng global population, he concluded his address with a surprisingly utopian vision for the future, highlighting the dual forces he believes will save the planet: "I see two immensely positive things, I see technical solutions that can fix climate change, and I see the prospect of a human race that no longer expands with Malthusian structure."
