The energy transition is accelerating — solar, storage, electrification. But as energy systems become more connected and more distributed, they also become more exposed. In this episode of  Raw Green , Francesco De Lieto and Emma Mee speak with Uri Sadot , Managing Director of Solar Defend (https://solardefend.eu/) , about a topic that is quickly moving from theory to reality: cybersecurity in ene...

Carbon fibre is one of the most advanced materials in modern engineering. It makes aircraft lighter, electric vehicles more efficient, wind turbines stronger, and high-performance sports equipment possible. But behind these advantages lies a major challenge. Producing carbon fibre is extremely energy-intensive, manufacturing generates large amounts of waste, and recycling composites remains techni...

For more than two decades, companies have relied on emission factors, spreadsheets, and high-level averages to calculate their carbon footprints. But what if this entire system is fundamentally flawed? In this episode of Raw Green , Francesco De Lieto and Emma Mee speak with Spencer Brennan , founder of Neutreeno (https://www.neutreeno.com/), about why today’s carbon accounting methods often fail...
