3:15 pm
university of patio. thank you. okay, so much more on that story of course i'm dw, the comes please do follow us to take the jar and great invalid. thank you for the good news. innovation green the green revolution global. so listen to a whole lot of crime. it's probably up to speed if the carriers subscribe to the subscribe to plan, it's a the of the
3:16 pm
new solar energy project and the tank of desert of china. it's set to become one of the world's largest and will supply over $2000000.00 homes with electricity in china as l squared renewable energy is becoming lower cost solution. then fossil fuel, the port of albert denmark blazer being loaded for an offshore wind park. and the north sea is it's beautiful. it's a symbol of green energy. right now the world is going through. it's great is transformation since industrialization. 150 years ago. to beach climate change, fossil fuels will need to be phased out for renewable energy. but is that even possible? and if it is, what do we need to do to successfully make it happen?
3:17 pm
the, it looks a bit like giants performing a dance routine. these rotor blades are among the largest in the world soon they'll be turning to the coastal winds of denmark, north sea, providing energy from a source that can never run out. al board is a key location for the transition in energy production engineer ava nielson is helping make this transition possible. i remember my 1st a 1st time i saw a plate moving, it was lifted from the mold and was moving under the roof. i imagined it that it was worth like us, is that it was as a ship and just moving a both me because it was so huge and douglas, assuming surprised me the long blade and now we have 115 meters the i still get some chris when
3:18 pm
i go in production homes and i see at the end of the whole several hundreds of lead us away, i can see small people up to 18000 households can be supplied with energy from a turbine of this size. here in albert, german, spanish manufacturer, siemens can mesa is building some of the largest wind turbines in the world. in the future, however, it won't just be about building as big as possible, hyphen move in the future that would be much more focused on the, on the waste. our customer will come with the men spent in demand. so we'll come into the contracts that will have to, to, to improve our folks all the time. so that will the, now it's a big news that we can, we can make and recycle blades with all this time. that will be something that we will need to do because the way we have to improve the way we're building. currently the fiberglass competed blades can't be recycled by 2030 though. all rotor blades made and albert are to be fully recyclable.
3:19 pm
the zeros answer, the phone. and once we finish, we close the form. and then we put a proxy. so the proxy is if the cookie to combines all the materials and all the confidence into together. and the big it big is like a cake. when we finished baking, we opened up the mold and then we have to plate. it'll be even more important in the future. that wind turbines can be recycled at the end of their service life. as we build ever more of them off shore on the open seas, where today there are thousands, there will soon be tens of thousands. for me it's like a simple off to image. if you have a plate, this is a slice of a bird that i would not mix of it. this is what you see from the outside is what most people see when they look at the 2 events. but as an engine. yeah, i also look at the insight, we will have this strength where they have to reinforcement so, so it's super interesting and it's really,
3:20 pm
really nice. the high end technology has been good for growth over 20 years. the planted l bork has expanded to provide around $700.00 jobs. sarah maci was offered her as well. she was still studying what's really interesting is that when you have this great phone activity produce, you have a lot of modeling industries that kind of follow that. so that means that when we make blades, you need someone who tests them, you meet the, you mean, actually stable way to transport it. so you had a lot of growing together when you actually start out with a project that was to see what i'm working with in his physical form and knowing that i was able to help make this. that's insane. he grabbed the floor and it really gives a lot of joy in my life. and the, and that's invaluable. denmark is a pioneer in the field of wind energy and a global leader in the transition to
3:21 pm
a carbon neutral economy. lena bar for it is the deputy mayor of copenhagen addressing the issues of technology and the environment. when i was a kid, it was kind of the 70s. we were hit by the prize like a lot of other countries. and of course, a lot of a political resources were put into how can we reduce energy consumption. but also a lot of people in copenhagen denmark site, i'd say we want to produce energy that we can be show off. so a lot of people started to look at wind and solar power. wind power covers over half of denmark's usage, the highest per capita in the world. mad snip a seals are stat builder of offshore wind farms. the way out see the globe move race against time to fight climate change is that there is no competition. the only partners on the green transformation and we need to help each other. we need to
3:22 pm
share or technology innovation. we have across awards with each other, not make it proprietary. because if it's, if one small country convinced great solutions and it only helps a small country, then it won't help the boys. and the rest of europe benefits hugely from denmark's know how and wind energy to while in denmark, wind power already mix up more than half of energy supply is only around 25 percent in germany. denmark shows that this change is possible even without major restrictions on demand. the green transmission that is necessary is not a fault. how can we go back to the stone age showing the seeing. the green transition is the possibility to make new lives new way of living. that could be a lot better. how can we completely transition to renewable energy? what will that mean for society?
3:23 pm
these are some of the questions that the pottstown institute for climate impact research is addressing this into them. so what else the a z is if you, if we need many, many different technologies, right? i didn't high quantities one because of a failure to a knocked climate policies over the past 15 years from c. r o is very important to understand how huge the challenge is or some years ago we were discussing that. if we don't do anything, then we will have the big climate change, and that would be terrible. now we have to say, it's not something that would come into the future. it's here now. if we are to achieve sustainable climate policy, will need renewable energy in 2022 for the 1st time, there was as much money invested into renewable energy as into fossil fuels. the majority of europe's new wind turbines are currently in the north sea, off the coast of germany and england. in a few years. the power generated is set to be able to supply half of the used population just a few years ago. these sorts of magnitudes were barely imaginable,
3:24 pm
but things have changed a development which also benefits german, wind farm operators. offshore into the flu, and offshore wind was an asset class. everyone used to laugh about, see if you wind turbines offshore and the german nor see or the u. k. the today that has completely changed all of the backbone of our energy transition stand rivaling large power plants are offshore. wind farms are comparable to coal fired plants, even nuclear plants, full cost exclusive, the north sea, but also the baltic sea outs. fantastic potential, especially if off showing is this. i know most of it was a, it's a huge, expensive ocean z home with potential to build 300 gigawatts. the following kind of 300 gigawatts of power from the wind farms in europe's northern seas alone equivalent to over 200 nuclear power plants. it could supply up to 300000000 households, a tenfold increase over its current output. the
3:25 pm
germany's power great operators are also preparing for the shift you that always, i think everyone's realized would bone succeed in north sea. and other places will most likely be able to generate to future energy reliably with sun, many countries and to use. yes, think about it, lindsay. so in so many industry represents tips on board and foot lead. i think the consensus is that it really has become fluids. the world's largest wind turbine test center is located in are still off the western coast of denmark. here they're looking into how to improve the stability and efficiency of the turbines. they're to withstand the forces of nature for 20 to 25 years and came out of conditions that were considered untenable just a few years ago. a super calm,
3:26 pm
but you'll also see the really rough wind what it can do and how these structures play with nature. so when it's really windy, you couldn't really hear that the wind is pulling in the plates. as a wind turbines, output increases sodas, it's cost effectiveness, increased efficiency, ultimately impacts the price of electricity for end consumers, both for household and for industry. we started to interstate in 10 years ago with a much smaller turbine, that was 6 megawatts in size. and i think it never becomes routine because every year, every 2 years, we expand that the turbine size is significantly even when the wind is blowing. the pace of the use transition to climate neutrality is determined by the speed of adoption of greener energies. northern european countries will need
3:27 pm
a considerable amount of wind turbines as they build out their networks on sea and land. it's why s b or denmark has built to europe, the largest shipping hub for wind turbines. in just a few years, all of these here will be supplying electricity also to new industrial centers. so that are being built along the new energy networks. vivian's and us know, you believe we'll see industrial companies, new investments and locations aligning with where energy is particularly great and where is particularly cheap. so i think there's a close connection between transformations and energy systems and future industrial policy industry party taking that. so the international renewable energy agency has also noted a correlation between sustainable energy supplies and economic up turn. it even the it transitioning to renewable energy is the project of the century. which means
3:28 pm
rebuilding our industrial structures. irina is predicting a 380 gigawatts target for 2013 and even 2000 gigawatts by 2050 with improved take. those are global targets. 2000 gigawatts is enough to provide a 5th of humanity with power to progress, especially where wind energy is concerned. is astonishing. nevertheless, the pace of expansion would have to pick up significantly to hit that self imposed target. and prices would need to continue to fall as themselves mostly kind of this does via and we've had a few extremely inspiring developments and technology and with folks of all tax. but we've seen that the cost of energy being generated by the palms, a full and by a factor of 10 between 20102020 c. that's breathtaking cycles and see and on. so i to the twenty's, does this possible the 2nd pillar of the energy
3:29 pm
transition is solar power. it too has seen rapid technical advances. the 1st solar power plants used thermal heat to generate power mirrors focus solar radiation onto a tower generating temperatures of up to a 1000 degrees celsius minerals such as salt or melted. they store the heat, which can then be used to power turbines and generate electricity at night, or in bad weather. they're known as concentrated solar plants, initially expensive to operate. they are now experiencing a technical and economic renaissance in madrid, jose luis, out of narrow works for a major spanish technology group, analyzing investment opportunities in renewable energy and those type in
3:30 pm
the fios, but i don't understand how long what it is from a technological perspective. i mean, we're striving to be at the forefront by using the latest solar panel models and technology. so what i like by facial panels or finding out the best way to optimize our inverters and things like that. well, the best thing for you is that gonna be the prospects for growth in foldable takes in spain are incredibly promising. all of the necessary conditions are years in the plenty of land, solar energy. so a well connected infrastructure and being motivated supporters for actively developing project the spain has invested extensively into new solar plants. now and it's funny is read in the country enjoys very low production costs for solar power. when compared to many other parts of europe. the constant advances in technology are now also leading to smaller systems with the centralized applications. the concentrated solar process remains essentially the same. mirrors
3:31 pm
focus the sunlight, directing it on to a storage medium. in this system, water in a drainage system is heated. the steam drives the turbine, which in turn generates electricity. that's fed into the grid, the if the spanish in the north sea regions, existing capabilities were utilized optimally. they, with the help of the sun and wind, could cover much of use energy requirements, something becoming more and more possible with the following costs of renewable energy. when they might just suzana named each month as of yet that's a lot to use it. and you can see that we went on my way to a system that suit based on fossil fuels was the renewables by the end of it, it gives us the fundamentals of that. but the question remains to how do i scanned
3:32 pm
it? so often times, before the worst case clinic catastrophe occurs. um it does if i tried to come, we'll just, we'll do. we'll do. just have to keep my car to school, thoughts of the how do we scale up the building blocks for such a system? scientists around the world are asking themselves the same question in berkeley, california. professor jan lynn together with beijing's ching, while university is researching the influence, energy generation has on climate change. in the past, people typically assume going clean or green, or inc from new york technology or an economy didn't cost you more, is no longer the case in china as a l square. renewable energy has to be coming lower cost solution then fossil fuels . in china, 2 developments in sustainable energy generation are seeing
3:33 pm
a rapid upswing industrial waste plants in areas no longer being farmed or turning into gigantic solar farms. around 80 percent of the country's rising energy needs are still met by fossil fuels. but that's such a change. china wants to double it's solar and wind power capacity by 2030. this would place the large country alongside the european union. as a global leader in the transition, the dig into $4.00 per site, we're predicting that 60 percent of global investment into energy transition will happen in asia, in the 40 percent of thoughts in china. and, you know, it takes sort of a coordination on massive scale. there's still a lot of a so called bond on in the road as your transition, so completely to or carbon neutral economy. but climate change is a global challenge that would require global classroom actions from all
3:34 pm
sectors of the world, both public and private, both industry, government and the citizens. large solar parks are being built on the water and in the mountains to an infrastructure is also coming along by capacity power lines that carry electricity to where the world's 2nd largest economy needs at most in its industrial centers and large mega cities analysis. they have demonstrated that as clean energy become cheaper than the traditional fossil fuel energy, you're going to save money for consumers and manufacturers as the money saved can be recycled. so we economy investment in consumption that will lead to a higher level economic growth. and more in jobs a new solar plant is currently under construction in the tank of desert.
3:35 pm
it's set to become one of the largest in the world, supplying more than 2000000 households with electricity. projects of this magnitude don't only directly impact china's energy industry. given the science of chinese economy was that these had to move to a certain direction able to effect the technology costs and innovation process globally decreasing costs and increasing efficiency. if the potential of solar and wind energy is harnessed consistently a full transition could succeed on a global scale. worldwide, researchers are currently hard at work on technologies to advance energy generation . in california is silicon valley. there's a special focus on materials research. the scientific community sees this is vital
3:36 pm
to the transition to renewable energy. the hope is to increase the efficiency of production that's making it even more affordable. in order to achieve these goals, we need to understand on an atomic level how energy and matter interact. stanford university is home to the world's largest linear particle accelerator with this 3 kilometer long machine. researchers want to find out how certain materials can absorb, store, and transmit energy with as little loss as possible. professor norbert whole camp played a key role in the machines design. the german american has an international research group, the cutting funding destination stuff out of the mind that i'm yeah, because the california is california or isn't like the rest of america and above the california was in many ways a trail place. you see here and all team is you look around as
3:37 pm
a spectrum of nations is in some ways to approach things to of it's great and also getting the front of the toys. we all the answers on the mail and we worked very closely with several attributes. she should have a whole pa, tooth around the well, ya pure dependent korea and south korea course, totally honest and many other countries that come visit to us and not the use of facilities to collaborate with us come and come back again to this guest research as soon as customers are traveling adults, with this gigantic machine around 3000 researchers are hunting for the smallest particles of matter in order to understand how they affect certain materials and how those materials can be further improve the gym to void. a. been an excellent, we're showing interest in this building the electronic center, right?
3:38 pm
so the only thing and then the kinetic energy is converted into x right causes pain . those x right pulses are extremely intensifier on to see about a 100000000 times more intense than any other x rays or if every show and then what we physically screw car here. and let me do this in science. this can use this lots of materials. we're searching can on the process of acquiring the very few lasers in the world like this one that this one was 1st demonstrated here in 2009. and i'll get to show that something like this does in fact well. and then suddenly, within 10 years, let's say there's 7 more stuff in the one who i talked investigating in 2009, it was proven that a laser shot at matter over a very long distance, leaves immeasurable mark at an atomic level institutes and laboratories can ducting basic research in these areas have sprung up alongside the stanford particle accelerator. this is where the materials are created. that will one day help with
3:39 pm
our energy needs. steve eyeglass leads one of these laboratories. in this lab, we develop new materials and chemistries for batteries. new architectures for putting batteries together. we develop scalable processes for manufacturing those materials at large scale for the world's energy transition. and we make small batteries that we can actually test and use in real operating conditions. the battery technology is currently developing much like the way micro chips have becoming increasingly smaller and more powerful. without ships, modern life would be wholly inconceivable. the same goes for batteries to they are necessary for the transition away from fossil fuels. yet they're still too heavy and too expensive for many applications. a race in global research has been happening in this field to so touched is just the feeling materiality.
3:40 pm
and so basically it is indeed true for us in order to truly usher in this new era. new materials will needs to be tailor made to specific uses. so if you're under no solution that incentives in the move this guy to have the possibility to assemble materials like lack of pregnancy are just as you want them to ball and beyond. it's a big challenge of cause and lots of people are working on. it was always portal and if it's successful at the most, it will have a huge impact in almost vehicle when it's a foreclosure. this age and a half 1000 kilometers away from stanford in copenhagen chase. vega, it's a global research group at the technical university of denmark. it compares world wide scientific findings and makes them available to researchers a key concept and what we're doing is developing what's called materials
3:41 pm
acceleration platforms. and the, uh, you can think of them as scientific legal blocks that you can construct with legal blocks in different colors from different countries to solve or to build the specific capital that you are interested in, in building. so it's you can say, continue is the operating around the world, 247, gathering the data that's needed, controlling experiments and equipment at other places it's, it's really a global challenge. and the global solution research so elaborate and complex that it would be inconceivable without international cooperation and exchange. once a year, berlin's falling walls science summit springs together leading experts, scientists, vega, and whole can have also been invited. the hot topic at the moment is artificial intelligence, with the immense amounts of data from global research a i could help find the most promising approaches faster than any human k. a i
3:42 pm
guide the discovery is really key to what we do. but having the right players in the wall room is actually essential. so yes, we can do a lot with artificial intelligence. but imagine that processing techniques that are required for that specific material to not scale. we need the input from the produces the manufacturing industry to get that integrate into the design process, the system to develop the gradual process too much. sometimes if you're lucky can lead to joining the steps forward in cycles. i will just refer to this problem, of course has to be solved globally, is enough to just solve one problem. but if you want to make this a better, well, you really have to cycle hold of. and so that's my business. i live, i'm good. singapore is considered a major hub for research into future technologies. there's a high concentration of world renowned universities and the small city states. many research institutions are collaborating with large globally active companies. on
3:43 pm
the advanced technologies of our time. the goal is to test research results quickly identifying any applications for industrial mass production, so that successes can hit the market as fast as possible. the professor hughes institute to is focusing on research into new semi conductor materials. they're used to convert solar energy into electrical energy. the particular attention is being paid here to a mineral called pair of skate. it's special crystal structure, insures higher efficiency in solar cells.
3:44 pm
so that's how they make a power sky, the base of attendance on ourselves. so this, our power is colored this the boxes and because the powers guys are very sensitive to the last here and also oxygen and the here are you thinking of also they have a feel wondered person to an average and at the most fear and the which allow us to make a deficient on a stable power. and this solar cell continue to absorb the layers. why is the power sky otherwise i'll go on it. and this the why is the way things which are pen g t and the con, the 3523.4 percent, which is the word like or for just kind of have all the solar cells the higher the efficiency, the more electricity generated care of the money work on the sort of services. and so there are kind of like a, a bridge between the university and the industry. and the here we want to a center is a transition funds a lot for the actually the national university of singapore. it has
3:45 pm
a reputation comparable to that of stanford in the us or oxford in britain here, interdisciplinary research is being conducted into future green technologies with a focus on solar power. i think we shouldn't be optimistic. we just take solar energy as example 20 years ago. why's us now? the cost difference issue a $100.00 times difference? we never, it's fast to be so cheap. so feel renewable, which it is. if we fix the solar energy, as example, we started 20 years of all, few dollars per kilowatt, right? and over the years through the continues, if us of many researchers, and there's actually mix in terms of the size that we can expect. now actually, and some of the places the world is on a light fuel stands per kilowatt. something crucial for the future of solar energy . one of the leading centers for research in this field is the california institute
3:46 pm
of technology. solar cells using new materials are developed here. professor harry atwater researches there development when i began my work in solar energy, the world had less than one megawatt total across the entire world of solar power. we now have as of last summer, more than one terror. what electric power generated by sort of a tech, so a 1000000 se, gross, that's just under a quarter of renewable energy sources total output. but of course nowhere near enough for a complete global transition. it's estimated that 20 terrell watts will be needed to meet this goal. researchers like add water hope to keep improving their materials. internal science is a platform for innovation for sustainable energy. it's a very,
3:47 pm
very powerful platform because almost all the renewable energy technologies that we are working on now, whether they be solar cells, fuel cells, batteries, electric chemical cells that make hydrogen or uh, you know, reduce c o 2 and do all of the things that we're trying to do, to build a sustainable energy economy. they all rely on materials. something being researched all around the globe in order to move as quickly as possible. researchers need to work closer together than ever before. developers of, of new technologies, new materials have fantastic equipment available, fantastic resources, experts in different domains, different places. but we need an infrastructure that supports that we can use that and exchange data to perform the experiments that i'm most essential to gather the missing piece of information that's needed to for the development of,
3:48 pm
of the new materials. we need to discover new materials that have higher energy density for electricity storage, new materials that can produce higher solar to electric or solar to fuel conversion efficiency. we were able to achieve record efficiencies for generation of hydrogen from water splitting. that actually was a collaboration with the technical university of illinois now in germany. yet another example of successful international cooperation on to germany to the omen now, university of technology that the engine energy research institute here was founded with the aim of bringing individual areas of research together. experiments to test the practical applications of research for industrial processes are carried out as quickly as possible. together with his colleague add water from pasadena, professor thomas han apple is conducting research into the components of the 21st
3:49 pm
century is most important resource, semi conductors. they can be as tiny as they are complex and made up of different layers of materials to create perfect harmony within that layering a mastery of basic mitch cereals is required to understand how they all work together. the goal here is to achieve the greatest efficiency possible when what you really have to understand things down to the atomic level to get the main components to ultimately run flawlessly. and the elemental reactor can heat matter up to 1000 degrees celsius. at that temperature, materials can reach a perfect level of purity. once the semi conductors are free of impurities, they can be assembled like a lego set. and stacked 2 layers and studies. doing so helps improve the efficiency
3:50 pm
of existing semi conductor materials and could allow for the creation of completely new materials. so you can basically say the actual reactor. here's the sample. here's what the gas comes in, flowing over the sample. air, it takes another minute to reach its boiling point, once the pressure and the reason the results of hun and i can start the process for temperatures. but we're no aiming for this sample which are the kind of bits and phone 1000 degrees. the temperature is slowly rising, connecting such highly complex research to practical applications like this is unique reactors like the one in elman. our also used an industry. everything that's needed for swift implementation on a large scale it's already on hand to
3:51 pm
exist. combination is pretty original. standing up on locations may have comparable approaches. the fact that we do this balancing act here, directly linking of science and then just the process. jesus was, it is the solution which i believe is unique in the world's design speed isn't everything, but it's highly important in the race to a green or future for a long time government's had other priorities. the focus was on the use of fossil fuels and research and to nuclear energy just as a sort of the 6 fits and what's happened really want to we lost them over 15 years as a global emissions continue to rise, etc. as we've also realized that the effects of climate change and much more dramatic than we thought 15 years ago, that's in 10 minutes. we need to have even more aggressive climate. it's august. the speed of transformations need to get from
3:52 pm
a current state to an emissions need to systems we need to increase also in every source, not try window shrunk from 50 or 70 years, like from just 25 all fluid santiago. so that's why scientists are under pressure to deliver results that can quickly reach industrial maturity. additional ideas are being pursued today. that sound a bit like science fiction. like harnessing the power of the ocean or capturing solar energy in space. at the california institute of technology, the space solar power project is pursuing the bold plan of collecting solar energy directly up where the earth atmosphere doesn't get in the way from there. it could then be beam to relay stations on earth. from the we're just demonstrating here today a couple of small scale,
3:53 pm
very small scale prototypes of the photo voltaic cells being designed for the space solar power project. the space or power project is aimed at building the components of an ultra light, very large scale solar power generation system in space. so every satellite in space nowadays uses solar panels to power. satellite operations are typically satellites are relatively compact structures. they're a few 100 kilograms at most, but what we're aiming to do with the space or power project is develop scalable fabrication methods for building very large scale power systems that could go to the megawatt and you know, hundreds of megawatt scale in space. and which would allow us to wirelessly transmit the power back to the earth and use it on earth. even this experiment in space would not have been possible,
3:54 pm
had it not been for the great leaps, made in materials research. photo vol techs have seen incredible breakthroughs. yeah, well it turns out that the materials that are most suitable, in fact, are inspired from some of this work that we have done in fordable techs and solar fuels because they are semi conductor materials and insulating materials. the kinds of materials that we use in, in, in those other lines of research. in january 2023, a prototype of a self unfolding solar array was launched into space for the 1st time. with it, professor ad waters team hopes to see how feasible a future solar farm could be. each one is expected to measure 3 kilometers by 3 kilometers, at least to start the ideas to assemble several such elements into giant's solar farms. for the big advantage is that it is never nighttime in
3:55 pm
space. if you go far away from the earth to a g, a stationary orbit, and you point your solar collector at the sun. it is noon on a sunny day, 24 hours a day. and as a result, you generate on a day night cycle basis, much more solar power in space than you do honors in space. there is no limitation to neither sun nor size. the energy harvested could then be beam to receiving stations on earth in the form of electromagnetic waves the very much like the way your cellphone, or your mobile phone works, where you transmit a signal from a antenna to your phone or from your phone to the base station, we can use the same frequency radiation to transmit power from space to the or
3:56 pm
a breakthrough was reported in march 2023. for the 1st time, the solar array prototype sent electricity back to earth. so the technology works in principle. it will be years though, before it can be used in practice at stanford and around the world. researchers are thinking far ahead about making a full energy transition possible below. and i would almost say we're racing towards what i quoted an energy revolution that might sound dramatic of the fast. and so the future prospect that she to show us and say, listen, we need to get young people excited about stem professions, about renewable energy. so that they joined as soon as possible that has to happen . these fuels have many jobs waiting for them. they just don't know what you ask if we need them up hopelessly. science and technological innovations have made tremendous progress and recent years. and in
3:57 pm
the major industrialized nations and around the world, the political will for transformation is there. but there is still a long way to go before green energy is powering every thing on earth. we don't know yet. how would we be in 20 or 30 years? but who have to side on it and some of the decisions we take now. we know that may be in 1520. yes. we will look back and say that was a wrong decision. but we have to try today. not simply, someday actions need to be taken that bring us towards the sustainable energy of our future. the
