We can produce abundant, sustainable and cheap energy — for everyone, says physicist Julio Friedmann. He explores the infrastructure, innovation and investment needed to supply energy to 10 billion people, offering case studies from Chile's refurbished supply chain, built in partnership with Japan, to Namibia's budding clean hydrogen production, inviting us to envision a greener, more equitably powered world.

How to harness abundant, clean energy for 10 billion people

Supplying 10 billion people with abundant, sustainable, and cheap energy is not just possible, it's necessary for progress on climate, health, food, and poverty. Every day, the sun delivers 163,000 terawatts of energy to Earth, yet today the world uses only 26 terawatts. Transformative examples from Chile, Kenya, and Namibia reveal how investments in infrastructure, innovation, and systemic financing can unlock global energy potential. Collective action and optimism, not scarcity thinking, will power a thriving, equitable future.
