“Sustainable AI means using AI without destroying the planet.” – Pascal JolyWhat if the next great challenge for AI isn’t bias or privacy — but energy?In this episode of The AI Lyceum™, Samraj Matharu speaks with Pascal Joly, a Silicon Valley product leader turned sustainability advocate, to unpack the true cost of intelligence: the carbon, water, and energy footprint behind AI.Pascal combines decades in cloud and DevOps with environmental science, helping organisations cut emissions and build greener systems — including AI Wattch, an open-source tool he built to track LLM emissions in real time with Antarctica, a climate-tech firm. Together, they explore how to balance innovation with planetary limits — and why sustainability may be AI’s defining test.From the greenwashing vs. greenhushing debate to tools like Electricity Maps, AI Wattch, and the AI Energy Score by Hugging Face.EPISODE HIGHLIGHTS0:00 ➤ Introducing Pascal3:15 ➤ What “Sustainable AI” Really Means7:00 ➤ How AI Creates CO₂ and Water Impact10:40 ➤ The Data Centre Energy Race14:10 ➤ Green IT vs. GreenOps Explained17:00 ➤ What Consumers Can Actually Do18:30 ➤ Tools: Electricity Maps, AI Watch, CodeCarbon, AI Energy Score22:45 ➤ Using AI for Sustainability (Climate Tech Examples)26:00 ➤ Training vs. Inference – The True Energy Split30:10 ➤ Making AI Development Sustainable37:00 ➤ Greenwashing, Greenhushing & Corporate Truths43:00 ➤ Recycling Heat and Water in Data Centres45:30 ➤ Small Language Models & Embedded AI49:00 ➤ The “Swiss Army Knife vs. Chef’s Knife” Analogy52:00 ➤ Why Pascal Is Cautiously Optimistic54:00 ➤ Audience Question: How Concerned Are You About AI’s Footprint?KEY QUESTIONS ANSWERED➤ What does “sustainable AI” really mean in practice?➤ How do AI models create carbon and water emissions?➤ Which tools can measure AI’s energy footprint in real time?➤ What’s the difference between greenwashing and greenhushing?➤ Why are small language models (SLMs) key to efficiency?➤ Can AI itself help solve the climate crisis — or is that wishful thinking?🎧 Listen on Spotify: https://open.spotify.com/show/034vux8EWzb9M5Gn6QDMza🎧 Listen on Apple: https://podcasts.apple.com/us/podcast/the-ai-lyceum/id1837737167🎧 Listen on Amazon: https://music.amazon.com/podcasts/5a67f821-89f8-4b95-b873-2933ab977cd3/the-ai-lyceum📺 Watch on YouTube: https://www.youtube.com/@The.AI.Lyceum🌐 Learn more: https://theailyceum.comHosted by Samraj Matharu — Certified AI Ethicist (Oxford) | Visiting Lecturer (Durham) 400+ members from OpenAI, DeepMind, Oxford, Google, and more.#AI #SustainableAI #GreenIT #GreenOps #EthicalAI #ClimateTech #AIWatch #ElectricityMaps #SmallLanguageModels #HuggingFace #DataCenters #ResponsibleAI #MachineLearning #AIResearch #AITransparency #EnergyEfficiency #GreenComputing #FutureOfAI #TheAILyceum #Podcast
