A global solar PV waste TSUNAMI is about to hit!
11:21 | Solar PV panels are multiplying at almost virus-like speed all over the planet. That’s a great thing for the transition to sustainable energy, but a massive potential problem for a catastrophically ill-prepared recycling industry.
How Hip-Hop Can Make Climate Action Cool
9:46 | With artists MyVerse and Kristen Warren as an inspiring opening act, social entrepreneur Samir Ibrahim suggests hip-hop and its stars can help us move from talking about the problem to rapping about (and acting on) solutions.
A climate solution you might not think of
11:36 | Research shows that the unwanted by-product of the mining industry, rock dust, could be a transformational supplement to agricultural soils all over the world.
Meltdown in the Himalayas – The politics of climate change
25:55 | The word Himalaya means House of Snow, and is the second largest icecap outside the polar regions. But it is melting at the fastest rate in human history. Pakistan takes a bold bid to mitigate worsening climate change.
DONG to Ørsted: The Oil Giant That Turned Green
7:35 | This is the incredible story of how a nationalised oil and gas company, from the tiny nation of Denmark, became a renewable electricity powerhouse in just seven years.
Annual Arctic Sea Ice Minimum 1979-2021 with Area Graph
0:47 | This visualization shows the expanse of the annual minimum Arctic sea ice for each year from 1979 through 2021, with a graph overlay.
Extreme Weather Events – The New Normal?
53:17 | “Extreme Realities” investigates one of the most critical issues of our time: the link between severe weather events, climate change, and threats to our national security.
Gravity Energy Storage. Who’s right and who’s wrong?
11:10 | Gravity energy storage has real potential to provide cheap reliable grid balancing electricity to compliment the ever growing volume of intermittent renewables on our power grids, but only if it’s done in the right way.
Klimakamp på flere fronter
1:00:00 | TV Udsyn har set på: Den lokale målsætning om at Odense Kommune skal være klimaneutral i 2030. Det teknologiske arbejde med at omdanne CO2 til flydende klimavenligt brændstof. Og en personlig indsats for et bæredygtigt liv i landsbyen Begejstringe.
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.
