The Pentland Firth is the strait that lies between the far north of mainland Scotland and the Orkney Islands. It's a wild area with some of the fastest tides in the world, where the power of the sea is being harnessed by tidal turbines sitting on the sea bed.But this type of green energy is still very expensive to generate - so what is the future of tidal and wave power? We explore some of the ground breaking projects being developed in the region and speak to companies who are trying to reduce costs to make the energy more viable.

Folge vom 26.03.2024How do you keep food cold?Up to 40% of food in Africa and India is wasted because of a lack of what's called "the cold chain" - the infrastructure keeping food chilled and fresh, from farm to fork. Many small-scale farmers have no access to any kind of refrigeration, meaning they're losing income and wasting food that could otherwise be sold.Devina Gupta meets the entrepreneur who is building pay-as-you-go solar powered cold rooms in India, and hears from farmers, traders and experts on how we can keep food cold as the population grows and the planet warms up.(Picture: A farmer carries a crate of mangoes from an orchard on the outskirts of Bangalore.

Folge vom 25.03.2024Will high interest rates be cut soon?The past few years have been marked by two economic trends that have affected pretty much everyone on the planet. The first is the cost of living crisis that followed the Covid pandemic and was made worse by Russia’s invasion of Ukraine. That saw prices in the shops soar - in many countries they rose by their fastest pace for four decades. The attempt to stamp out this inflation is the second of those big economic trends, as central banks aggressively increased the cost of borrowing. Millions of households and businesses saw the cost of home and company loans shoot up.But the action taken by central banks does seem to have worked in curbing inflation, and now financial markets predict that interest rates in the United States and Europe will be cut this year. But will they reduce them soon?(Picture: Federal Reserve Building in Washington, DC, United States. Credit: Getty Images)Presented and produced by Rob Young
