In this episode of Climate Confident, I sit down with Dr. Jemma Green, Co-Founder and Chairman of PowerLedger, to explore how blockchain technology is reshaping the energy sector. We discuss the shift towards peer-to-peer energy trading, how utilities can adapt to a decentralised grid, and what role blockchain-backed renewable energy certificates can play in ensuring transparency and accountability.

Dr. Green explains why traditional feed-in tariff models are becoming unsustainable, how local energy autonomy can reduce grid congestion, and why distributed energy solutions are key to managing growing electricity demand. We also dive into the economics of vehicle-to-grid (V2G) technology and the impact of Europe’s Clean Energy Package on decentralised energy markets.

Takeaways from this episode:

• Why utilities need to move beyond traditional energy supply models
• How blockchain ensures trust and efficiency in energy trading
• The economic incentives driving distributed renewables adoption
• What energy prosumers (like EV owners) can do to optimise costs

We also touch on India’s approach to energy decentralisation, regulatory hurdles slowing adoption in Europe, and how businesses can benefit from corporate renewable energy trading.

Tune in to understand how technology is driving the future of sustainable energy.
