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.

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 this first episode of a four-part miniseries, Sherrell interviews environmental health scientist Dr. Sacoby Wilson on what happens when data centers infiltrate a neighborhood. They discuss why data centers disproportionately undermine working class communities and how Dr. Wilson is working developing ordinances to better regulate data centers and holding planning commissions accountable.

If you’ve tried AI and felt underwhelmed — or if the constant pressure to “just play around with it” makes you want to throw your laptop across the room — you’re not alone. But according to Max Mullen, co-founder of Instacart and one of the most practical thinkers on this technology, you might be closer to becoming an AI expert than you realize. In this episode, Max makes the case that expertise with AI isn’t about taking a course or spending your weekend trying to learn how to use it. Max talks about how to use AI to solve real problems, why you want to try it more than once, and argues that building a relationship with the tool is the key to getting better and faster results. This is the episode for anyone who’s skeptical, behind, or just exhausted by the hype.

Electric vehicles have a surprisingly long history. Battery-powered cars have existed since 1881. So why did the world choose to spend over a century investing in fossil fuels? Sherrell explores this question with a talk from engineer Doreen Orishaba. Doreen built Africa's first electric vehicle and now runs 100+ electric buses across East Africa. Her success proves that the countries that did not inherit a broken infrastructure may be best positioned to build what comes next. Then digs deeper into the background of electric cars in a TED-ED lesson from Daniel Sperling and Gil Tal.
