Energy expert Sebastián Kind helped Argentina go from virtually no renewable energy to generating nearly 40 percent of its electricity from wind and solar in just six years, despite economic crises and skepticism. How did the country's...

Clean energy visionary Lei Zhang loves the Gobi Desert — the most Mars-like place on Earth. Why? Because of the promise it holds to provide the free, abundant solar and wind energy to fuel humanity’s next leap forward. Sharing the story...

How did a small, economically vulnerable country become a trailblazer in sustainable industry? Clean economy builder James Mnyupe explores how Namibia is teaming up with partners from around the world to turn sun, wind and water into...

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...

Impact investor and Acumen CEO Jacqueline Novogratz unveils a bold vision to bring off-grid solar electricity to 700 million people still living in darkness, transforming lives while slashing emissions. She asks a thought-provoking...

Fighting climate change is much like long-distance running: a complex journey filled with obstacles, fast-changing conditions and the need for constant adaptation. Drawing on his own experience as an ultramarathon runner, energy expert...

How prevalent is solar power, really? According to researcher Jenny Chase, it's already displacing fossil fuels in key energy markets around the world. She explains the rise of affordable solar power and dives into how her team tracked...

Industrial manufacturers spend a huge amount of energy generating heat to make everyday materials and objects, like cement, steel, and paper. And since most companies use fossil fuels to reach these high temperatures, industrial heat...

What if solving poverty, caring for nature and fostering well-being were the ultimate goals of the economy, instead of growth for its own sake? Environmentalist and economist Gaya Herrington proposes a shift in thinking from "never...

Here's a wild stat: nearly one-third of the world's food production goes to waste each year, a major contributor to the climate crisis. Farmer and UN climate champion Gonzalo Muñoz sheds light on the international negotiations aimed at...

The clean energy transition has a major blind spot, says energy equity expert Sheila Ngozi Oparaocha: it ignores millions of people without access to energy. Highlighting grassroots women's organizations leading the charge towards...

The basic infrastructure that controls plumbing, electricity and more is vital to your individual agency, says engineering professor Deb Chachra. She offers a crash course on how these systems connect to shape our lives — and suggests...

Why aren't restaurants part of the climate solution? This question inspired chef Anthony Myint to go from opening buzzy pop-ups to pushing for a shift to regenerative farming practices in the food system. He explains how it didn't go the...

In 2022, physicist Tammy Ma and the team at Lawrence Livermore National Laboratory achieved a scientific breakthrough decades in the making: fusion ignition, or the combining of two atoms to generate more energy out of a reaction than...

Typically, with any piece of technology, you pump one unit of energy in and you get about one out. That’s just the first law of thermodynamics: energy has to be conserved. But there’s a piece of technology called a heat pump, where for...

Stars have cores hot and dense enough to force atomic nuclei together, forming larger, heavier nuclei in a process known as fusion. In this process, the mass of the end products is slightly less than the mass of the initial atoms. But...

When you think of newer ways to make electricity, solar cells and wind turbines may come to mind. But scientists can make the stuff from just about anything. And they're working on some truly bizarre ways to generate power.

Hundreds of millions of people lack access to electricity in Sub-Saharan Africa, relying on highly polluting diesel and firewood for power and light. Working to brighten the future in her home country of Malawi and beyond, energy access...

The world relies on manufacturing, and manufacturing relies on heat — a massive contributor to global carbon emissions, responsible for a quarter of the world's fossil fuel use. Energy entrepreneur John O'Donnell has figured out a...

Climate innovation leader Rich Powell dives into the bureaucracy, bottlenecks and not-in-my-backyard attitude preventing the US from achieving its green energy goals, warning that we need about 10,000 new clean energy projects to be...

The world has plenty of clean energy. The problem is storing that energy and getting it where we need it, when we need it, says battery recycling pioneer Emma Nehrenheim. While batteries are fundamental to powering a sustainable future,...

In the US, people spend the overwhelming majority of their time inside buildings that burn fossil fuels, which are bad for both the environment and human health. (Think: breathing in air pollution from gas stoves, furnaces and water...

We've heard news of "peak oil" and "the end of the oil age" for years now, but we keep coming up with ways to find and pump more of it to the surface. Rising CO2 levels and the changing climate that results from burning fossil fuels mean...

Fifteen years ago, Uruguay was experiencing an energy crisis brought on by its reliance on fossil fuels; today, the nation produces 98 percent of its electricity from renewable sources (and even exports extra energy to neighboring...
