PRAISE FOR DISCIPLINED ENTREPRENEURSHIP FOR CLIMATE AND ENERGY VENTURES The energy system is challenged simultaneously to deliver reliably and affordably while minimizing emissions and serving the needs of investors. Technology and business model innovation are the essential tools for meeting this complex challenge, and MIT's Climate and Energy Ventures class has, from its inception, supported and developed entrepreneurs whose success we all depend on. This book captures the insights gained over fifteen years by faculty and students alike and, as such, provides an invaluable guide to those who will build the clean energy economy.--Ernie Moniz, Former U.S. Secretary of Energy Addressing the closely coupled climate and energy challenge is the moral imperative and economic opportunity of our generation. I have watched the MIT climate and energy entrepreneurial ecosystem from its start and as it has successfully grown well beyond MIT. I know that at the core of its success have been rigorous frameworks to bring research to market. This book describes the MIT model in ways that should be useful to all current and aspiring innovators in this field.--Susan Hockfield, President Emerita, MIT There is no pathway or prescription to successfully address climate change, nor energy security, economic and environmental well-being without energy innovation. This book makes accessible to everyone proven, actionable, entrepreneurial strategies arising from one of the world's greatest epicenters of innovation. I highly recommend it to all.--Andy Karsner, Former Under Secretary, U.S. Department of Energy, Current Member of Board of Directors, Exxon Mobil, Managing Partner, Emerson Collective Disciplined Entrepreneurship for Climate and Energy Ventures is more than a guide--it's a catalyst for action. What sets this book apart is its tailored focus on the unique challenges and opportunities within the climate and energy sectors.--Georgina Campbell Flatter, CEO, Greentown Labs Through my personal journey in building companies and supporting hundreds of entrepreneurs, I know that the learnings are hard won, and the journey can feel lonely. This book captures best practices that I hope every entrepreneur can benefit from to accelerate their progress and build world-changing companies.--Carmichael Roberts, PhD, serial co-founder of multiple deep tech companies, Co-Founder and Managing Partner, Material Impact, Co-Lead, Investment Committee of Breakthrough Energy Ventures
