Ice hockey was hit hard by the pandemic, with empty arenas and financial losses threatening the sport's future. Now in 2025, North America's National Hockey League (NHL) has come roaring back.

We'll look at that journey and how the sport is about to enjoy a record-breaking season with predicted revenues of $6.6bn.

The small country has big ambitions to become a tech and innovation hub.

It has a reliable source of renewable energy, thanks to the Itaipu Dam - a huge hydroelectric dam on the Paraguay-Brazil border.

We hear from government ministers and business leaders about how they believe they can make it happen - and the benefits it could bring, particularly to young people in Paraguay.

A new type of solar cell has been developed and has made it to market.

Perovskites have been called a 'magic material' that many believe will be the new, efficient way to convert the sun's energy to electricity.

Now the material is being used on commercial roof panels for the first time, we look at the opportunities of the new tech, its flaws, and when it might be available to households.

In the final episode of our series, we've gather together a panel of experts who all have an interest in critical mineral mining.

Demand for minerals like cobalt, lithium and copper is growing rapidly, as countries turn to green energy solutions. These minerals are used in EV batteries and wind turbines.

So what does the future hold? How do countries approach China's dominance in both mining and processing, and what about the environmental and ethical concerns?

Rising demand for critical minerals to fuel the green energy transition means an expansion of mining around the world.

New mines are opening, existing mines are being scaled up.

In the fourth programme in our series, we find out about the impact of mineral mining on the planet and for those people both working in the mines and living nearby.

We head to the Democratic Republic of the Congo where there are claims that child labour is being used in so called ‘artisanal’ mines and there is little scrutiny of the supply chain.

China’s headstart in market dominance is significant, and its grip on critical mineral supply chains remains tight.

The question now is whether other governments can move fast enough — and smart enough — to build something more secure, more sustainable, and less dependent.

We head to La Rochelle in western France for a rare look inside one of the world’s biggest rare earth processing plants, and find out what it reveals about Europe’s efforts to build a supply chain of its own.

The country dominates the global processing of critical minerals - materials essential to clean energy, defence, and modern manufacturing.

In the second part of our series on the global race to secure these resources, we explore how China built its control over the supply chain, from strategic state investment to partnerships abroad.

We also head to Indonesia, where Chinese firms are leading the charge in nickel processing. Has one country gained too much power over the world’s green transition?

They’re essential to the green transition, modern tech, and defence systems—and global demand is soaring.

In the first part of our series on critical minerals, we ask what they are, where they're found and why they matter?

As countries scramble to secure supplies, we explore the rising geopolitical tensions shaping this fast-growing industry—including the Oval Office standoff between Presidents Trump and Zelensky over a landmark minerals deal.

It’s been 10 years since Ireland made history by becoming the first country to legalise same-sex marriage through a public vote.

While other countries had legalised it, it was the first time a referendum had been held.

We hear from wedding planners, photographers and venues about how things have changed for them since the 2015 referendum.

As the overall number of marriages in Ireland decreases, the number of same-sex marriages is still increasing. We hear from same-sex couples who are now seen as prospective clients for this sector.

Six months on, we head back to the Spanish city to hear from residents and businesses.

We're in Colombia where workers have been been shot at, threatened with violence and seen their work colleagues killed – all because of union membership or association.

Why is this happening, what’s being done about it, and what drives people to still sign up for trade union membership?

Nuclear power is back in favour, as more countries across the world consider ways to cut carbon emissions to combat climate change.

Countries like China and Japan are planning to build more reactors, but should nations in Africa invest in renewable sources of generating electricity, like solar panels, wind turbines and geo-thermal power, instead of nuclear?

We examine how energy generated from nuclear fission has huge advance costs which would mean African governments finding loans from willing investors, but that might cede more economic influence to China or Russia.

We also hear how Amazon, Google and Microsoft are investing in nuclear power, using smaller modular reactors to run data storage centres in the United States, as demand for electricity is expected to surge when artificial intelligence is running at full capacity. Could the developing technology of SMRs prove useful in Africa?
