destro company says it needs water now to make liquid soap laundry detergent and shampoo export to sunny hot enough if the worst. yeah. what is the soul of this fact? we can't do without it last week. even that is if tensor empty the 1st time and we had to send workers home here that may not be the last time. the water authority says, unless there's a drastic change in israeli policy, palestinians will continue to struggle with their basic human right to access water . and tosh again, al jazeera in the occupied west bank. ah, what, you know, just here? let's get a recap of the top stories. this our, the chief of the u. n's. nuclear watchdog says his talks in iran have averted a show down between these land mac republic and the west. iran has agreed to allow

inspectors to install memory cars in surveillance cameras and it's sensitive that nucleus on the coming together of the jigsaw puzzle will come when that he's an agreement at the j c p level. but at that time we will have all this. ready information and there will not have been a gap. so i think with, with this agreement we have today we are going to be able. ready to do exactly that, because our foreign minister has met with taliban leadership to address, humanitarian and security in afghanistan. mohammed been up to rom, and l fanny is the most senior official from any country to visit since the groups tyco van. north korea says it has successfully tested a new type of long range cruise missile over the weekend. the us military said miss l test conducted by north korea posed a threat to its neighbors. i didnt,

tanner's main opposition party is leading in the capital and the k province of one of fairies in the midterm primary elections. the vote is seen as a k test for president alberto fernandez, and the popularity of his ruling center left government in the primaries is mandatory and is often an accurate predictor of the final result. south african president, serial rema pose, says covered 19 restrictions will be lifted and a nationwide, if you shortened following a declining infections. but he has appealed for more people to get vaccinated to 7000000 people out of the population of more than 60000000. a currently fully protected and brazil's political movements, both on the right and left to join forces against president abel. scenario brazilians are unsatisfied with rising poverty, right? those are the headline stage. you can look my phone with my face. you can access your bank accounts with your voice unique algorithmic measurements of us that are

revolutionizing the process of identification. biometrics, a fall from 1st big convenience and seeming infallibility, comes across most crucially, our privacy. in the 4th of a 5 part series at a re addresses the appropriation of our most personal characteristics. all hail the algorithm on jazz. ah, me, we're in the middle of the biggest energy transition to industrial revolution. cove in 1900 pounds is excel rates, and i'll move away from fulfilled price tags of renewables, particularly solar,

comes down. it is now possible to actually imagine a carbon neutral world to run on clean energy. there is still a long way to guys with climate change. this time for that to bang, we must talk global greenhouse gas emissions by 2034 to have any hope of reaching that sir, by 2050, and avoiding the worst effect global warming. so the change while it is happening, needs to happen quicker in this program will be looking at 2 of the solutions that have a part to play in that transformation on the all the islands in the u. k. scientist working with one of clean energy is holy grails, green, hydrogen, and in norway, a carbon neutral data center is using the force of nature to power our digital life . the global demand for energy is increasing, but burning fossil fuels is polluting and it's warming upon it with devastating

impact for life on earth. while renewable energy from when sun and sea cheaper than ever intimated, it's difficult to store. a few of the future is emerging, which could prove fundamental to de carbonite in the global economy. i've come to the orkney islands of the north coast of the u. k, where a network of scientists and researches approving the missing link in the next renewable energy revolution. might be found in the simplest and most abundant elements. hydrogen, the universe is about 73 percent hydrogen, mainly occurring as gas. but on the earth, most hydrogen is contained in water, is the h in h to row. after it's generated from water can be used as a few posts cause buses and even spacecraft. but in order to extract it from water, you need electricity. when that's produced using fossil fuels,

that contributes to greenhouse gas emissions. in order to be known as the energy islands, scientists have discovered how to produce green hydrogen using renewable power, generated by wind farms and title turbines. it could be a game changer. ah, a meeting, a del lydia dale who's a hydrogen project manager and was brought up on orkney. just let me know when we have a sense of self. i should be, we need to do thanks for our sales doctor for we're not really get in touch on the island community. we come to shop and say when a bought me 13 inhabited islands to see how they produced kind of a job to possession of small, quiet island for quite a high tech energy brochure. this turbine is owned by local residents and produces more energy than the local grid can handle. the excess poet is used in a hydrogen production. i'm no scientist,

but i could see on the train that says explosive compress gas. yep. and what is actually happening behind these, this fits what's going on in these boxes. so if they're working energy production sites, before i was done in our site, what's the connection between? when did hydrogen, we have the wind turbine going round here today. when it reaches a certain meter for 2nd, we switch the energy production over to produce hydrogen. these metal boxes contain the key piece of machinery and electrolyte that generates hydrogen gas. and electric current flows through the electrolyzer causing water to break down into hydrogen and oxygen. hydrogen is collected and compressed, so the electrolyzer, it just takes normal drinking or use of the energy from the wind turbine. it splits each to washer and to hydrogen and oxygen. we capture the hydrogen for you for energy and the oxygen at the moment. it's just a tough fear, so your re diverting that wind energy into hydro, right?

as storing and storing it's transported by trailer and used all over me. some in domestic heating, but mostly in commercial vehicles. and fairies in the trail is the hydrogen stored under pressure at $184.00 times. it's original density. that's a lot of energy. a meeting with james ferguson, a specialist and hydrogen storage. the highly inflammable gas is locked away in compounds and the key sight. oh wow. oh gosh. so one of the big advantages of hydrogen is that it is a kind of option for seasonal energy storage. and that's when we want to store a lot of energy over months. so we know that in the u. k. during the winter, it's very blue, it's very windy. if we go to a wind turbine based energy system, we're going to have a lot more generated in the winter than we need. and so we can capture that and store it from the form of hydrogen,

and then keep it until the summer when we don't have any wind blowing and, but we're still using energy that was. so how is hydrogen used as a fuel where? well, james has a rather knotty way of demonstrating this with a toy car that looks about what 20 mills. he shows me how to produce hydrogen with many electrolytes. so we just wait a moment, we're going to generate some hydrogen. we're going to get build up an electric current passing through the water forms hydrogen bubble. now, some gas storage here that we didn't have before. now i'm going to take my cable round here and you can see now that the gases are flowing into the fuel cell. and then that's going to allow us to generate electricity, which means the cargo that is absolutely better catch the principal, the pose, the fuel cell in james is toy car is the same when scaled up to power. a fleet fight council ban on the island. well, completely silent. oh,

completely silent. wow. you can sometimes hear the compressor from the hydrogen when it's when the, it kicks in it, you know, here we, well, that's all you here. david hannon is working with the council to expand its use of hydrogen technology. so for a long time, we're talking about electric vehicles as being the future of, of green transportation. what do you get? the hydrogen per vehicle that you wouldn't get of an electric vehicle? this is also a battery runs off battery. but then the hydrogen is yours to be extend the range on it. so if you're either traveling long distances, you can potentially double lot range and is another advantage. it's quick to review with electric battery. you might take from half an r t. it ours to charge battery, whereas this is pretty much instantaneous, you know, talking couple of minutes normally we'd expect to see an exhaust pick that the back of eventually this. yeah. and you can see there's no source here and the same as

any electric vehicle. obviously we've got hydrogen, but then the sort of emissions off out as water paper is here yet. right? wow. all right, really, i said with, with me it's great to hear. house seems to be growing all the time. and there's that awareness of the importance of this kind of network, or there's a quality of entity when you live in an archipelago. another important form of transport is very nice fe, company of re 74 different connections and there are more than 20000 sailings each year. but the fuel used in shipping badly polluting i, david for david, hidden who works with the fay company clean hydrogen is part of this plan to clean up the operation. and they all happens below deck. ok. have no idea what we get into it. but here we go.

oh wow. both the ship, what we looking at him. these cylinders contain towards the leadership fuel using the hydrogen, hydrogen i still want to invest system will run on a regular engine light steering safety systems and the, the lights and anything. and so when in the future, hydrogen will be used to drive all ships operations including propulsion, stepping within the stopping on small shipping steps and already established fans and fairies powered by green hydrogen just part of the picture in orkney, pioneering research into how the fuel could play a global role in transport and beyond is happening here at the orkney research and

innovation campus. one of the most important projects in aviation, in a normal year, nearly 14000000 flight schools. why each result in heavy field 2 emissions search for an alternative fuel. urgent, one company collaborating with scientists in orkney is 0 avia. i contact director survey kids a live and excited about their 1st 15 minute long hydrogen test plate. it was the combination of almost 3 years of research and frankly it was, it was for the baby. the game was already so excited at the same time. i know that you guys are planning to fly here with one of your hydrogen per claim o the final flight of our fire fire one project will be taking

place from for can you or can you use famous for it, the hydrogen? can you give us a time schedule of when you think that we will see passenger planes in the sky running on hydrogen? of course they're not going to influence you, but i personally believe that 15 to 20 years, they will be a lot of depth. why and using hydrogen, and this is truly exciting. so if we can rise to the challenges of our energy economy, our future transportation needs. it means embracing a range of solutions. and i think what they're doing here orkney is proving the green hydrogen me pot. the green hydrogen is beginning to take home. it's a key part of the ease, the well 1st carbon neutral constant by 2050, a new projects being developed in chile, saudi arabia, the united states. yes,

there is still a way to go before green. hydrogen is proven to be scalable and cost effective, but it is gaining traction. and it's one of a number of current trends that harold, a world free of fossil fuels, is definitely a new power system and a new energy assistance emerg bar i. whether we look at power, generation and distribution, or whether we look at transports, there is no doubt that we are in the middle of the most consequential transition in the energy space that we have seen in 100 years. it is a very exciting moment. it's also a nerve wracking moment because we know that if we don't get to half emission by 2030, it will be too late to do anything substantial about climate change. this is our last window of opportunity to bend the curve of emissions and get on to a did to track undoing society. would be

a society that has one represent clean energy. that energy would be centralized, cheap, ubiquitous. we would be able to provide power to every single home on this planet. we currently have 800000000 people who do not have the power, meaning they're in abject poverty, by moving over to 100 percent clean energy d centralized. we can make energy big and we can bring those were under the line of poverty over that line. a green society would be an economy that has smart grid that has storage available to all renewable energy generation. sources would often be society in which there is efficient and clean transport. passenger vehicles would offer transport as a service,

not being a possession of any individual. and heavy traffic would be using clean field and finally, city would be clean wyatt because we would have put the internal combustion engine into them and that he would be organized into smaller community, around food and energy at the beginning of the most just science, the decade in the history of human kind, it behooves all of us to understand that this has been challenging and will continue to be challenging. but we can do that. we can address climate change in a timely fashion. we can avert the worst dispatchers, the climate change, and in so doing, we can bring a much better quality of life for all citizens of this planet and certainly to the

ecosystem upon which we depend ah, in people across the planet offending an increasing amount of time on line from work meetings and catching up with friends to move it streaming and shopping. we are now more reliant than ever on platforms which generate and store data. but this data doesn't just vanish into thin air. it comes at a very real environmental costs. everything we do on line passes through data centers which consume huge amounts of entity and emit nearly as much c o 2 as the airline industry. i'm in no way to see how one center is honda thing. the energy of the fuel was to stole our digital information without a heavy, comp and footprint. but this is a famous tourist attraction and photo hotspot focused on the no way. it rolls

hundreds of thousands of visitors every year. i'm curious to find out what people know about the data, all these photos generate. so when you take a selfie, it land somewhere. have you ever met in where that could be? i think the 1st time i would imagine if you're asking, i haven't been thinking about it. no, i have no idea. i send it to google, i guess in the now in the cloud. and do you know what the cloud is? a big storage place on the night myself, most people only have vague ideas of where all our data has kept. i've come to university of savannah to meet an expert on data storage and find out where ourselves, he's end up. the photo is, will be stored in the memory of their phone and then if you'll share the photo while you want to back up the photo into the cloud,

it will end up in some data center remotely could be in europe. it could be also in a remote fi across the atlantic and both they have accumulated in those data center and those walls for us to have a big big data center. so the problem for sustainability, how long, how much data we have to store them in recent years, many of us have been moving into the digital realm and even more so under the corporate 19 pandemic year for their study. so that our online habits take a heavy toll on the environment. a typical search which passes through data centers processing and storing information requires as much energy as illuminating a 60 what light bulb for 17 seconds. that doesn't sound like much until you realize google alone processes 3500000000 searches

a day. around one percent of electricity globally is consumed by data centers, many of which provide for note storage facilities or what is also known as the cloud is estimated that in 10 years is our data network grows. almost 7 percent of all electricity will be used just to power and qu huge service, preserving everything from billions of family photos to big data on space travel. so where and how you stole your data can make all the difference. and no way is ahead of the game on this, since it's powered nearly a 100 percent by renewable energy, most of which comes from hydro power. i'm on my way to benefit an island near. i've heard to have an old military storage, but instead of storing to pito hits, they now stole billions of bites of information all over the world. the underground green mountain data center which opened in 2013 is carbon neutral. it's right on

hydropower from water rest of us on the mountains. so question nice to meet you. nice to meet you as well. ah oh wow. this is like being in a james film. i can see that this is very secure. this is very secure. wow, thank you though this is how it looks when we took over there to fight here is empty space, but it will not be empty forever. as soon as we grow, this will be a data center as well. so know we're entering what people refer to as the cloud. this is where our customers are running their server storage equipment.

so what kind of information is still here? it could be anything from storage, your picture to national critical infrastructure. if you'd be kid at home doing their lecture online, so many people when they think about the clouds, they think out in the open as they're saying, white and fluffy. but actually the cloud is miss tally and it's black and it's noisy, it's black and it's noisy. and it consumes a lot of power and generates a lot of heath to see how the center manages this. it's a quick write down the oh, where in the future road, this is where all the green energy flows through into the data. so this is basically the giant engine of this data center. the consumption in this data center

with all the different data holes at consumes the power equal to about 20000 households. while this may seem a lot, some of the biggest data centers consume as much power as the city of a 1000000 people. every click you do on your device, generate at the inside data center summer. if it's in norway, it's green and renewable as well. so using green energy, this data center is reducing its impact on the environment by cooling its service using cold water from the nearby deep salt water inlet of yard. so while most data centers use around 40 percent of the energy to cool servers, which would otherwise reach a 100 degrees celsius in minutes, this data center get to cooling free from nature. so this is where we're producing the cold water use to cool the cloud, a cold sea water from the fuel into the basin next to the data

center. this water which is constantly 8 degrees celsius, is then pumped up through the heat exchanger cooling down, separate water pipes that circulate through the data center. the warmed up feeble to the exits back into the fjord at around 20 degrees celsius. where'd quickly cool down again? the green mountain data center in no way is unique because of the fuel cooling the servers. and the way in which they've repurposed an old site. but all over scandinavia tick giants like facebook, google and microsoft are building huge data centers running on hydro and wind power . in fact, investment in nordic data centers is set to double by 2025. thank you, or be both fully electric. i'm meeting theory kelvin, a local matri ologist in green investor who's confident this trend will continue. so this is where the hydro power is. yes, the over the flu. hydro station,

it's actually the world's longest $4444.00 step over 100 year sold. so be careful though, i can see that it's old from this old train here. here you see the old pipe coming down from the mountain. so all the water's just flowing high speed in the pi, creating electricity when they hit the turbine. so you have to use for nature gives us. so in norway we have incredible rain or the concrete have sun. yeah, we also have wind, but here it's rain that gives us the electricity. scandinavia will be important to the world for data storage. i think scandinavia will be very important for future data storage. it's a cold climate. if you can use the cold fury to, to cool down the data center,

we have the hydro poll were to run data centers. however, i think we also need to be even more responsible and take action the each one of us . and for instance, if we are talking on both data storage, we need to be concerned about how many celsius we need to take home many emails, some snaps and text message. we need to send me though we can't see it. our use of digital devices has an impact on the world around us. this is only set to grow. nearly 60 percent of the wealth population is already online and around $1000000.00 new uses sign up each day. as our reliance and data expands, we need to find greenway to manage it. here in no way, i've seen how this can be done. and i really need to learn from examples like this and make sure that we balance our modern lives with what the planet can sustain in

which so many of us stuck time during the pans. i make it perhaps hard to see that the world really has been given a golden opportunity for green recovery commitments are happening all over the place. as nations businesses, cities, investors pledge 0 carbon target by 2015. but right now 20 per year. that's just under a decade determine the future of the planet around the world already think glimpse of the green society that could be our last year, renewables over to fossil fuels as a main source of electricity in europe. a new case in australia to the solar panels on rooftops, one in for hi me. the know was that photo complex to morocco, studying its 1st phase, and it's already producing enough energy to power the city of my ra cash, twice those 60 percent of month. the call 1000. no. why are these cars will be banned? there in 2025. the solutions that already that they just need to go global. make

a real difference, ought to have shown that the green and prosperous future. ah, russellville and southern england, where 2 farmers turn safari park, pioneers of the attractive nature in the driving seat are just absolutely astonishing the life, the poor back even that the very 1st and i miguel sophie, i, cynthia when one by miriam companies revolutionizing the system. you think blend and artificial intelligence here in flight. you have science, you have the right phone, else are 0 teaching. you can watch out for english streaming live and i get 2 channels plus thousands of our programs award winning documentary and do get
