How to fight climate change with parking lots

How to fight climate change with parking lots

8:31 | Solar photovoltaics researcher and professor Joshua Pearce goes into the data on how placing solar canopies over parking lots could be a worthwhile investment for many cities.

Wind power’s unsolved problem

Wind power’s unsolved problem

10:46 | Wind turbines are playing a big part in cleaning up our energy system. But the blades are close to impossible to recycle and largely end up in landfills. There are more and more companies promising to fix that. Can they?

Have we got enough minerals?

Have we got enough minerals?

13:05 | Will batteries for hundreds of millions of future electric vehicles rob the planet of all its precious minerals? And what about all the minerals and materials for billions of wind turbines and solar panels?

How Wireless Energy From Space Could Power Everything

How Wireless Energy From Space Could Power Everything

10:54 | 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 power and then beam it down to Earth.

How solar energy got so cheap

How solar energy got so cheap

6:30 | Since 2009, the price of solar energy has come down by 90 percent. That’s no accident. It’s the result of policy interventions from the US to Germany to China.

48:51 | Artist Marjan van Aubel argues for a ‘solar democracy’. The moment solar technology is linked to aesthetics and design, a whole new perspective emerges.

Batteries are dirty. Geothermal power can help.

Batteries are dirty. Geothermal power can help.

8:00 | In Indonesia, where the majority of nickel for lithium-ion batteries is produced, the production process emits large amounts of carbon and pollution. It doesn’t have to be this way. Indonesia sits along the Ring of Fire, one of the most geologically active regions in the world.

Perovskite solar cells. Major new breakthrough!

Perovskite solar cells. Major new breakthrough!

11:30 | Perovskite structures have the potential to revolutionise the solar PV industry, but they are notorious for breaking down very rapidly in real-world use. Now a research team from Princeton University has developed a process for overcoming that problem.

Driving on Solar

Driving on Solar

47:26 | The solar car, an electric car with built-in solar panels, will be on the market in 2022. From 2030 onwards, no new cars may be sold in the Netherlands that run on petrol or diesel.

Why wave power isn’t everywhere (yet)

Why wave power isn’t everywhere (yet)

11:16 | The oceans, that cover most of the planet, are full of energy. So much, in fact, that if we could harness that of all the waves, we’d fulfill global demand three times over. There’s just one small problem.
