Today in many countries solar is the cheapest form of energy to produce. Millions of homes are equipped with rooftop solar, with most units paying for themselves in their first seven to 12 years and then generating further savings. So,...

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...

Obviously, you can’t just plant a chip in someone’s head and start manipulating their thoughts and behavior, but doctors and scientists CAN use electricity to activate or inhibit certain parts of the brain. And they can use this power to...

We’ve had a number of false starts that did more harm than good to figure out new treatments, and ECT is one of those treatments that came from a complicated history.

If you've ever been stuck at a red light on a country road, you know it can be annoying. No other cars for miles, but you can't shake the feeling that if you run the light, one will appear out of nowhere and slam into you. Today we have...

We all know the words around electricity -- _charge," _positive," _battery" and more. But where do they come from and what do they really mean? Let the history of these words illuminate the physics of electric phenomena.

Shocking the brain has come and gone as a medical treatment, but it’s currently resurging, as it often provides the best form of relief for severe depression and advanced Parkinson’s disease. ___________________________________________...

This Nobel Prize season, dive into the world of the super small for physics and chemistry. It's where the nanocars roam and phase transitions get really weird.

Jessi and Squeaks learn about special spots on a shark's face that help them find food using electricity!

Alternative energy is great, but our infrastructure isn't exactly equipped to handle it. So scientists are coming up with other ways to use it, including turning it into food.

As climate change accelerates, finding clean alternatives to fossil fuels is more urgent than ever. Social entrepreneur Vaitea Cowan believes green hydrogen is the answer. Watch as she shares her team's work mass producing electrolyzers...

Stretching over roughly nine million square kilometers and with sands reaching temperatures of up to 80° Celsius, the Sahara Desert receives about 22 million terawatt hours of energy from the Sun every year. That's well over 100 times...

Real World Telekinesis (feat. Neil Turok)

Solar power is cheaper and more sustainable than our current coal-fueled power plants, so why haven't we made the switch? The real culprits here are the clouds, which make solar power difficult to control. Alexandros George Charalambides...

Pulsed plasma thrusters use the same stuff that’s on your frying pan to make spacecraft zoom around the universe. And they’ve been doing it since the 1960s.

One potential avenue for cancer treatment uses electricity not from any outside machine, but from within our own bodies.

The internet uses a lot of energy! But people have come up with ways to make it more efficient.

What if we took out more greenhouse gases than we put into the atmosphere? This hypothetical scenario, known as "drawdown," is our only hope of averting climate disaster, says strategist Chad Frischmann. In a forward-thinking talk, he...

What if smallholder farmers could use their produce and livestock to pay for goods and services? TED Fellow and alternative currency enthusiast Fariel Salahuddin is working to make this a reality in places including rural Pakistan, where...

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...

All around the world, millions of people are flipping a switch, plugging in, and pressing an 'on' button every second. So how much electricity does humanity use? And how much will we need in the future? Discover how much energy it takes...

David Thouless, Duncan Haldane, and Michael Kosterlitz won the Nobel Prize in Physics in 2016 for discovering that even microscopic matter at the smallest scale can exhibit macroscopic properties and phases that are topological. But -...

Every 24 hours, wind generates enough kinetic energy to produce roughly 35 times more electricity than humanity uses each day. And unlike coal or oil, this resource is totally renewed each day. So how can we harness this incredible...

There is a chemical reaction discovered a century ago that could be the key to creating everything from fuel to shelter on Mars!
