In this episode of Raw Green 🎤 🌵, hosts Francesco De Lieto and Emma Mee - our new co-host (!) - sit down with Christophe Williams, CEO and founder of Naked Energy, to explore one of the most promising frontiers in clean energy: hybrid photovoltaic thermal (PVT) technology.

From advertising to clean tech, Christophe shares his entrepreneurial journey, and how Naked Energy’s solar innovation is changing the economics of renewable heat and power.

🔥 What we cover:
• What makes PVT solar different—and why it matters
• Naked Energy’s flagship tech: VirtuHOT and VirtuPVT
• Real-world performance and return on investment
• Key lessons from testing, certification, and failure
• Scaling up through partners like E.ON
• Innovative models like “heat as a service”
• The future of integrated, high-efficiency clean energy infrastructure

💡 Naked Energy isn’t just another solar company—it’s rethinking how we generate, distribute, and monetise heat and electricity in buildings.
