Why carbon capture needs a reality check

Why carbon capture needs a reality check

14:01 | Oil companies are pouring billions into technologies to capture CO2 at fossil fuel plants or even suck it out of the air. They have made big promises — but where are the results?

How we can make solar power at night

How we can make solar power at night

12:26 | Concentrated solar power can store the sun’s heat for a long time and turn it into electricity when needed – for example at night, when normal solar panels lie idle. Is it set for a comeback?

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?

The greenhouse gas no one is talking about

The greenhouse gas no one is talking about

11:39 | You may know laughing gas from your visit to the dentist. But did you know that it’s actually a climate killer – 300 times as potent as CO₂? Why is no one talking about it? And how can we to stop it?

Are climate doomers right?

Are climate doomers right?

Why electric cars are finally taking over

Why electric cars are finally taking over

10:41 | We’ve known how to build electric cars since long before Tesla came around. And yet, for more than 100 years, we’ve largely relied on the internal combustion engine to get us from A to B. But that’s changing – faster than we might expect.

Why we need to ditch natural gas (asap)

Why we need to ditch natural gas (asap)

11:55 | Natural gas is abundant, versatile – and much cleaner than coal. It lets us keep the lights on AND reduce emissions. That’s great, right? Well, yes. If it wasn’t for one small detail: it’s still a fossil fuel.

Is nuclear fusion the key to fighting climate change?

Is nuclear fusion the key to fighting climate change?

12:47 | All over the planet, billions of euros are being poured into developing nuclear fusion technology. And recent “breakthroughs” in plasma physics experiments have stunned the scientific community. Are we on the brink of an era of limitless clean energy supply?

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.
