Buildings are bad news for the climate -- but they don't have to be. While our structures are currently responsible for a third of global energy consumption and emissions, a future where they create more energy than they consume is possible. Energy policy analyst Ksenia Petrichenko has a three-tiered strategy for thinking differently about build...

In this intimate talk filmed at TED's offices, energy innovator Amory Lovins shows how to get the US off oil and coal by 2050, $5 trillion cheaper, with no Act of Congress, led by business for profit. The key is integrating all four energy-using sectors—and four kinds of innovation.

When it comes to cost, clean energy is bound to beat out fossil fuels, says technologist Ramez Naam. But the hesitancy to build amid the prevalence of "not in my backyard" campaigns is preventing the creation of our sustainable future. Naam outlines the changes we need to make to get out of our own way and create a stronger, more reliable renewa...

What would happen if we could generate power from our windowpanes? In this moving talk, entrepreneur Justin Hall-Tipping shows the materials that could make that possible, and how questioning our notion of 'normal' can lead to extraordinary breakthroughs.

Call it "fuel without fossils": Jonathan Trent is working on a plan to grow new biofuel by farming micro-algae in floating offshore pods that eat wastewater from cities. Hear his team's bold vision for Project OMEGA (Offshore Membrane Enclosures for Growing Algae) and how it might power the future.

Modern life runs on wireless technology. What if the energy powering our devices could also be transmitted without wires? Electrical engineer Ali Hajimiri explains the principles behind wireless energy transfer and shares his far-out vision for launching flexible solar panels into space in order to collect sunlight, convert it to electrical powe...

In this brief talk, Saul Griffith unveils the invention his new company Makani Power has been working on: giant kite turbines that create surprising amounts of clean, renewable energy.

No matter how we make electricity, it takes up space. Coal requires mines, and plants to convert it into electricity. Nuclear power takes uranium mines, facilities to refine it, a reactor, and a place to store the spent fuel safely. Renewable energy needs wind turbines or solar panels. So how much space would it take to power the whole world? Ex...

Africa needs new energy sources to fuel its development, but the continent should invest in renewable energy instead of cheap, polluting alternatives like coal, says climate inclusion activist Chibeze Ezekiel.
