Some companies are returning to an old concept, sail-powered cargo ships, to reduce the amount of carbon used to ship goods across the ocean.
From PBS NewsHour: “Eighty percent of all global trade travels by sea, and the ships carrying those goods account for 3 percent of global greenhouse gas emissions. Now, some shipping companies are taking a new tack as they try to navigate the industry to sustainability on the high seas.”
As climate change accelerates, finding clean alternatives to fossil fuels is more urgent than ever. Social entrepreneur Vaitea Cowan believes green hydrogen is the answer. Watch as she shares her team’s work mass producing electrolyzers — devices that separate water into its molecular components: hydrogen and oxygen — and shows how they could help make green, carbon-free fuel affordable and accessible for everyone.
From Insider Business: Alhaji Siraj Bah researched how to reduce deforestation and realized many trees were being cut to create fuel. He discovered a way to produce biomass briquettes from coconut waste for use as an alternative to wood for cooking fuel. Learn more about his company Rugsal Trading, which also produces paper bags.

World famous track cyclist Robert Förstemann battles a 700w toaster. Can he, with his 74cm legs, generate enough energy to create a golden-brown toast? Please like, share and comment! The challenge was set up to show how much energy we humans consume compared to what we can generate. This is a graduation project from the Stockholm Academy of Dramatic Arts filmed in Stockholm, Sweden. The finishing examples estimate how many Roberts that would be needed to power either a petrol car consuming 6,5l/100km for one hour, or a one-hour Boeing 737-800 flight.
European scientists say they have made a major breakthrough in their quest to develop practical nuclear fusion – the energy process that powers the stars.
The UK-based JET laboratory has smashed its own world record for the amount of energy it can extract by squeezing together two forms of hydrogen.
If nuclear fusion can be successfully recreated on Earth it holds out the potential of virtually unlimited supplies of low-carbon, low-radiation energy.
The experiments produced 59 megajoules of energy over five seconds, more than double what was achieved in similar tests back in 1997.
