11:52 | With 25% of solar in the energy mix Hungary is one of the world leaders in solar energy generation worldwide. But where does this spike in solar come from in a country not known for its sustainability?
10:38 | A new generation of small-scale hydro is promising no-emissions energy, without the large-scale impact. We take a look at three contenders: the vortex power plant, the hydrokinetic turbine, and osmotic power.
10:10 | Solar is booming worldwide, slashing costs and driving the clean energy transition. But this rapid growth comes with its cost: grids in countries like Spain, Australia and Greece have buckled under the pressure.
11:05 | The military has long used reactors to power submarines and aircraft carriers. Could this also work for commercial ships?
8:31 | From Ahmedabad to Boston, cities across the world are making big changes to cope with floods and heat.
15:04 | Tens of thousands of old wind turbines are set to retire globally every year – and many of them are bound to get scrapped. But some companies are trying to save them.
11:54 | Even the most EV-crazed countries can have so-called charging deserts where your electric car could run out of juice any minute.
11:20 | Solar power capacity has tripled globally in the last five years – and there’s more to come.
9:53 | Donald Trump rolled back decades of US climate policy in his first days back in the Oval Office. But how will his moves affect global progress?
11:35 | Around the world, city dwellers are scrambling to stay afloat – by raising walls and buildings, rewilding land, and relocating to higher grounds.
12:12 | Despite net-zero pledges, banks and asset managers, funds and governments continue to give trillions of dollars to the fossil fuel industry.
12:51 | Whether it’s creative accounting or lofty claims: Here’s what to look out for in companies’ climate promises.
11:16 | Wind has been outpaced by solar as the frontrunner of renewable energy. But according to some studies, recent innovations could unlock up to 80% more wind energy potential in the US alone.
22:22 | One project in Kenya covers an area the size of Slovenia and promises to offset carbon emissions by restricting where and when livestock can graze. But indigenous herders are crying foul.
12:02 | Somewhere below the Swedish city of Västerås, there’s a big man-made cave. The local energy company decided to clean it, pump it full of water and heat it up.
14:00 | The US is producing more oil than any country ever has, despite pledging to reduce emissions.
16:16 | Right now, millions of old solar panels are headed for landfills. But companies are still chasing the tech that makes it viable to reuse the recovered materials in new solar panels.
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?
11:56 | Gravity batteries are a new big hope for storing excess renewable electricity. The idea is ingenious. Does it pass the reality check?
12:20 | The idea was simple: why not use solar energy from Australia’s sunny and spacious north to power Singapore, which has no space for renewables of its own?
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?
12:43 | If you’re looking for a climate success story, you’ll find it, of course, in Scandinavia. Sweden has cut 80% of its net emissions since 1990 – while growing its economy.
9:49 | Fossil fuels still supply 80% of our energy. And people point to this number to say it’s impossible to switch to renewables. But their argument overlooks just how much energy we waste – and how we could do it better.
13:29 | Europe’s betting big on hydrogen – despite a lot of drawbacks. Is the continent’s hydrogen strategy overblown? And if so…why?
11:33 | I flew in the first ever e-plane certified to take off to figure out whether we will all soon be flying electric.
13:04 | The race to develop small modular reactors is on, with the promise to provide fossil-free energy everywhere. But only one has been built so far. What’s going wrong?
15:20 | The shipping industry is responsible for three percent of global emissions. One of its best bets to get these down is fueling their vessels with ammonia.
11:38 | Burning carbon, for example in the form of coal, produces cheap energy – but also tons of emissions. Why don’t we just tax that?
6:52 | People used to be really worried about peak oil – what happened? And does it matter if we run out?
13:15 | It’s almost impossible to pin down how much the military emits globally. We are talking about a sector with a budget of 2.2 trillion dollars using helicopters, tanks, ships, fighter planes.
11:33 | Heating our homes with cold water! Sounds absurd? It’s not. Heat pumps are revolutionizing the way we heat and cool our homes and cities. We went to the German city of Mannheim to find out how.
11:10 | Imagine creating solar panels without relying on materials in short supply and adopting an eco-friendlier production process. And at the same time boosting efficiency? Enter perovskite tandem solar cells.
12:11 | Biochar is supposed to suck carbon out of the air, reduce air pollution and even generate energy. But does it live up to the hype?
11:53 | A handful of solar cars are available for pre-order now, but how realistic is the tech?
11:06 | Truck manufacturers are under immense pressure to cut emissions. But should they bet on fully electric batteries, hydrogen fuel cells or even both?
11:26 | Planting Great Green Walls in an attempt to restore dry land has become a continental effort, led by governments and NGOs in both Africa and China. Now India has ambitious plans to do the same.
