Solar-powered LED lightbulbs could transform the lives of rural Haitians, but as Daniel Schnitzer found, they don't simply sell themselves. At TEDxPittsburgh, he shows how smart health and energy products for the developing world are...

So, if economics is about choices and how we use our resources, econ probably has a lot to say about the environment, right? Right! In simple terms, pollution is just a market failure. The market is producing more pollution than society...

We’re in the middle of a rapid, unprecedented, and world-changing increase in the intensity and scale of human activity on this planet.

As the world's attention focuses on the perils of oil exploration, we present Richard Sears' talk from early February 2010. Sears, an expert in developing new energy resources, talks about our inevitable and necessary move away from oil....

Of all the mundane yet astonishing marvels of human ingenuity, knowing what it takes to heat a room to a comfortable temperature is TED Fellow Kathy Hannun's favorite. She takes us on a journey across the planet and under the sea to...

So, what is fire, exactly? What causes fires in the wild, and how do we put them out? SciShow answers your burning questions about the science of fire. (See what we did there?)

It’s hard to replace jet fuel because the alternatives aren’t energetic enough, are too dangerous, or aren’t yet being made at scale.

There's a game of Tetris happening on a global scale: The playing space is planet Earth, and all those pesky, stacking blocks represent carbon dioxide -- a greenhouse gas that is piling up ever more rapidly as we burn the fossil fuels...
