KlimaTV – Vedvarende energi
16:19 | 15 million jobs are set to be lost from the fossil fuel industry in the coming years, but more than three times that will be created in the renewable sector.
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.
15:59 | Solar photovoltaic panels provide electricity for homes, businesses and utility scale grid providers. Ironically though, the hotter they get in direct sunshine, the less effective they are at producing power.
50:07 | In the season opener, David Letterman travels to India. Back in the U.S., Cecily Strong travels to Florida and Nevada.
10:57 | Denmark’s climate minister Dan Jørgensen lays out his plan to end the country’s oil industry by 2050 and transition to a fossil-free future powered by wind energy.
42:26 | Algae are perhaps the most adaptable and productive organisms on Earth. They’re an important food source, and their ability to provide oil could make them a replacement for fossil fuels.
15:59 | Algae has been used by humans for thousands of years, but the idea of using algae as a secret weapon to combat climate change is definitely a modern day concept.
12:16 | Solar, wind and wave power from a single offshore platform?
6:53 | Africa needs new energy sources to fuel its development, but the continent should invest in renewable energy instead of cheap, polluting alternatives like coal.
10:08 | A team in Cambridge has developed a film that can amplify the number of photons that a solar photovoltaic panel can use, with a potential increase in efficiency to as much as 35%.
9:50 | Fossil fuel replacement isn’t enough, Solomon Goldstein-Rose explains in this compelling talk: we need to rapidly develop a new global system capable of producing 12 times the amount of clean electricity we generate today.
11:18 | Solar power stations in space. Sounds like pure science fiction doesn’t it?
6:47 | Solar power is one of the fastest growing energy sources during the last decade and the global production has gone up from 21 tWh in 2009 to 724 tWh in 2019.
11:11 | Solar panels are highly sensitive to what you might call ‘sub-optimal’ conditions… a research team reckon they’ve overcome those problems by creating a spherical version of the common solar PV panel.
11:57 | It’s estimated that we could (practically) capture enough tidal energy to power all homes in the United States TWICE over – but we can only manage a tiny fraction of that right now.
9:02 | More and more solar panels are popping up all over the world – and it’s easy to see why: They provide clean energy at falling prices. But there are also some not-so-green sides to this technology.
Seat At The Table, Episode 7: I’m heading to Scotland to see how workers rights can be protected as we transition to sustainable energy. Plus we take a look at clean energy in Africa and the most powerful tidal generator in the world.
13:38 | Solar PV panels are now a common site around the world and they do a great job. But they only work on flat surfaces. What about the millions of other surfaces that are not so conveniently shaped?
15:10 | Deep beneath your feet is a molten ball of energy the same temperature as the surface of the sun — an immense clean energy source that could power the world thousands of times over, says Jamie C. Beard.
14:50 | One UK company have just announced a £16 billion project that will be generating 3.6GW of solar, wind and battery capacity in South Morocco.
10:35 | Wooden windmills are surely a relic from our pre industrial history aren’t they? Well, that was certainly true until recently.
14:16 | With wind almost always blowing on sea, there is no lack of power. But the technology is struggling with a bunch of other hurdles.
6:50 | Making clean energy isn’t enough: We also have to move it.
18:55 | The climate emergency requires climate solutions. And fast! A new analysis suggests that 90% of the job could be achieved by just a handful of disruptive technologies that are very real indeed.
The global freight shipping industry accounts for nearly 3% of all GHG emissions, so freight operators are on a quest to reach net zero by 2050. Here’s three of the most promising wind power options that could help them get there.
9:27 | What if we could not only harness the power of the sun, but actually use it to run the entire planet?
11:44 | The Port of Blyth boasts a world-class research hub for offshore renewable energy.
12:58 | Offshore wind turbines powered almost 40% of all the UK’s homes in 2020. IEA says there’s enough potential energy out there to power all of Europe, the US and Japan several times over.
12:37 | A jumbo jet sized floating platform supporting two large turbines has been launched off the coast of Scotland, providing new hope for a potentially influential industry.
10:16 | A major housing development in Austin, Texas is installing five miles of geothermal pipework to serve a Master Planned Community that will comprise 7500 homes and 30,000 residents.
14:28 | Agrophotovoltaics, agrivoltaics, or APV. Just like the name suggests, it’s a way of combining photovoltaic solar panels with agriculture.
10:59 | Kerosene lamps are still widely used in many parts of the world, not least by kids trying to study during the evenings in Sub-Saharan Africa.
12:08 | Most air flows just goes to waste. What if we could scoop that air up and do something useful with it?
17:48 | Switching to renewables is an important step towards a more sustainable future. Optimising the efficiency of those mining and processing operations can hugely reduce their impact.
14:02 | A new micro-hydropower technology is working with the natural flow of water and wildlife rather than against it, to bring much needed constant baseload power to off grid areas in remote areas of developing nations.
25:54 | India and China will most likely be key to the success or failure of our transition to a sustainable future. They’re now jostling for geopolitical power too.
11:11 | Biomass is held up by governments around the world as a net-zero carbon alternative to fossil fuels. Just like most aspects of climate change mitigation though, the reality is far more complicated than that.
25:37 | The cold winds of the North Sea could soon be providing warmth and light for millions with the first-ever purpose-built energy island.
10:37 | Solar Power is set to be the dominant transformative form of power on the mighty subcontinent of India as it moves away from its dependence on coal and towards a more sustainable future.
7:53 | A lot speaks for solar energy. It’s clean, renewable – and now even cheaper than energy from fossil fuels like coal or natural gas. But it only makes up a tiny bit of global electricity production.
6:08 | “Kur mod klimakaos” er baseret på NOAHs klimahandlingsplaner, der er lavet som et kritisk modspil til regeringens klimalov.
4:08 | Hydro energy is the dominating renewable energy source. In this video I visualize the development from 1965 up until today.
9:51 | The potential of geothermal energy seems enormous. If estimates are correct, then the heat under our feet amounts to 50,000 times more power than all the oil and gas resources in the world.
11:05 | India has a historic opportunity to power its industrialization with clean energy – and its energy choices will make or break the world’s fight against climate change.
4:02 | How the global Wind Energy production increased by 500 % in 10 years.
13:35 | Geothermal energy could be potentially transformational for our power grids. But you and I can also get in on the act by drawing our own domestic heating from beneath our gardens (or communal gardens if you live in an apartment block).
14:37 | Science tells us there’s enough energy in the first 10 kilometres below our planet’s surface to provide all our energy needs for millions of years. So why isn’t our entire planet powered by it?
25:42 | With two thirds of our planet covered by sea, maybe it’s time to look to the horizon for our future energy needs. Are floating wind farms the answer?
