How satellites are supporting farmers across Africa | Catherine Nakalembe

The best thing that could happen to the energy industry | Matt Tilleard

History has been written by whoever controls the dominant fuel of the era — until now, says renewables entrepreneur Matt Tilleard. He explains why, as the clean energy transition ramps up, we’re moving from a world where energy comes from burning fuels to one where it will come from using technology. Learn why this could change everything about global power dynamics — and why the future belongs not to those who control resources, but to those who build and share technology.

How to pull the emergency brake on global warming | Mohamed A. Sultan

Landfills across African cities are catching fire and releasing methane, an invisible greenhouse gas with more short-term warming potential than CO2. Sustainable strategist Mohamed A. Sultan reveals how local communities are turning this crisis into opportunity, diverting hundreds of tons of waste from landfills and helping thousands of farmers adopt more sustainable techniques. Learn why cutting methane emissions is a win-win opportunity to drive down global temperatures while also creating more livable cities. (This ambitious idea is part of The Audacious Project, TED’s initiative to inspire and fund global change.)

In 2014, the world’s second largest coal consumer made a bold promise: to increase its solar capacity from three gigawatts to 100 gigawatts in just eight years. Many people called it overly ambitious, but energy expert Kanika Chawla saw the opportunity of a lifetime. She tells the story of how India became a solar powerhouse, turning an expensive dream into an economic reality — and creating a model for other countries to follow suit. After, Sherrell reflects on what drives the green economy and the growth strategy other companies can follow.
