little gathering for the leaders, wary of a new year filled with unset president trump. uh, i say this respect for me is a business not by backgrounds. i think his engagement, in many ways would be transactional. and i think you were of needs to consider how we can make that case of id economic relationship. be a 2 way street the return of donald trump to the white house that goes more than a possible trade war with europe. it could mean pressure on ukraine to negotiate and into its real war with russia. you lead as a team to show that you can lead the way in supporting ukraine. the presidency lensky was here to tell them that isn't enough. y'all have you heard of ice cubes? i believe that you are p and guarantees will not be enough for ukraine. and this cannot be discussed only with european leaders. because for us, the real guarantees of today for in the future on nato. a wide ranging summit also discussed the use, placing the will economic li, stagnant,

buffeted by competing forces to the east and west. and there was cautious acknowledgement that the full of bus on the left side in syria could lead to the return of hundreds of thousands of syrian refugees. a welcome outcome for a number of member states. one city you will, you have agreed on the main principles and object use of our approach in response to the full of us of the resume and to ensure a peaceful and inclusive transition is a serious 330 of integrity insured respect for human rights, including you women's rights products, religious and ethnic minorities the you and the yeah. on something of a low. it's 2 largest economies from some germany in political crises, gross across the union, anemic and sitting on the sidelines of seismic events on fold in the middle east. little surprised and the many here view the return of the president. trump with

trepidation. jo, nicole elders, era, brussels, a call to in the front says found a man guilty of drugging and raping his former wife, recruiting schools of strangers to rates of a several years. just so how they costs ex husband, dominique are they called has been sentenced to 20 years in prison. 50 other manual also found guilty of rape case shots from sun spots and national debates about violence against women. that's it for me, you can find more features and analysis on our website just to also say are dot com and the media devices of a nice continue to on. so in the just on the huffman the screen 20 yes is the was it on the, on the record struck country the election an easier to for like to untie the

estimated 230000 people can join us as we speak just a 5 isn't victims is all the 4 in the middle of the biggest energy transition sustain joshua revolution. the carpet 19 content, mac is accelerating. i'll move away from fossil fuels as price tags of renewables, particularly solar, come down. it is now possible to actually imagine a cub unusual well to run on clean energy. but there is still

a long way to guys climate change as a guy with the markets thing this time. so about still the same. we must talk global greenhouse gas emissions by 2013 before to have any height of reaching that 0 by 2050 unemployed in the west effects of light, but will make the change one that is happening needs to happen quicker and this program will be looking at some of the solutions that have a part to play in that transformation on the all the islands and the u. k. site is to work and we'd want to clean energy is holy grails, green hydrogen, and in no way a comp and mutual data center is using the force of nature to power or digital lives. 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 a renewable energy for when sun sees cheaper than ever into mrs. difficult to

store a few of the future is emerging, which could prove fundamental to de carbon ice in the global economy. i've come to new york new islands of the north coast of the u. k, where a network of scientists, researches approving a 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 most hydrogen is contained in water is b h and h to go after it's generated from water. it can be used as a fuel depos cause buses and even spacecraft. but in order to extract it from what you need, electricity, when that's produced using fossil fuels, it 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 title turbine. it could be a game changer. the meeting and the lady do who's a hydrogen project manager and was brought up for an orkney. we have this sense of self sufficiency. we need to do things for our sales practice to not really care. we come to shop and say when the board is 13 and habits of the islands to see how they produce, i just kind of a small island this turbine is owned by local residents and produces more energy than the local grid can handle. so the excess power is used in a hydrogen production. i'm no scientist, but i could see on that that, that sign that says, am explosive, compress gas. and what is actually happening behind these display,

it's what's going on in these boxes. there were for working energy production sites, which is why we're sending it. sorry. what's the connection between wind that hydrogen? we have the wind turbine going right into your 3 am when it reaches a certain meters per 2nd. we switch the energy production over to produce hydrogen . these metal boxes contain the key piece of machinery and electrolytes. the generates hydrogen gas and electric current flows through the electrolyzer causing water to break down into hydrogen and oxygen. hydrogen st collected and compressed so the electrolyzer just takes normal drinking or it's use of the energy from the wind turbine exploits for each to oh, well sure into the hydrogen and oxygen. we talked to the hydrogen for use for energy and the option of the moment is just right spirit. so you're re diverting that when delta dental hygiene. that's right. yeah. storing and storing hard it's, it's transported by trailer and used all over organized some domestic heating,

but most of the commercial vehicles and ferries, in the trailers the hydrogen is stored under pressure at a 184 times its original density. that's a lot of energy. i'm meeting with james ferguson, a specialist in hydrogen storage. the highly inflammable gas is locked away in compounds and the key sites. yeah. oh wow. oh gosh. so one of the big advantages of hydrogen is that is a, 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 of in the u. k, during the winter, it's very fluid. 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 then we need. and so we can capture that and store it in the form of hydrogen, and then keep it until the summer when we don't have any wind blowing and, but we still using energy was. so how is hydrogen use as a few where?

well, james has a rather not a way of demonstrating this with a toy car that looks about. what's that test? that's about 20 news. so it shows me how to produce hydrogen with a many electrolyzer. so we just to wait a moment, we're going to generate some type of thing. we're going to get to build up an electric current passing through the water forms. hydrogen bubble is now got some gas storage here that we didn't have before. so now i'm going to take my cables around here and you can see now that the gases are flowing into the fuel cell. and then that is gonna allow us to generate electricity, which makes a target. that is absolutely good. yeah, that. so instead of catching the principal, the pose, the fuel cell in james is toy car is the same when scaled up to power fleet 5, cancel back. so in the island was completely silent. it's all completely silent. wow. so you can sometimes hear the compressor from the hydrogen when it's when,

if it kicks in it, you'll hear me. wow, that's all you'll hear. 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 green transportation. what do you get? a hydrogen powered vehicle that you wouldn't get of an electric vehicle? this is also a battery runs off the battery. but then the hydrogen is yours to basically extend the range on it. so if you're either traveling long distances, you can potentially double wide range and is another advantage. it's quick to review with an electric battery. you might take from half an r t it or the charge of operating, whereas this is pretty much instantaneous. you know, talking couple of minutes. normally we'd expect to see an exhaust stick that the back of a van like this. yeah. and you can see there's no source here and the same as any over electric vehicle. obviously we've got hydrogen, but then the as sort of emissions of thought as water paper is worth

a basement here. yeah. right. all right, really thank you. said with results is me. it's great to hear how it seems to be going all the time. and there's an awareness of the importance of this type of network or this ecology of energy when you live in an archipelago. another important form of transport is very often the fairy company operate 74 different connections and there are more than 20000 sailings each year with the fuel use and shipping by the polluting. david for david hitt, who works with the faith company create hydrogen is part of this plan to clean up. see what the ration nicole happens below that? i have no idea what we're getting to here, but here we go to

the southern desk and t 20 using decided hydrogen is doing the best system engine surprises, eating the safety systems and the the late in the future. hydrogen used to be stopping state funds in phase powered by green hydrogen just part of the picture in ok. pioneering research into how the fuel could play a global role in transport and beyond. it's happening here at the organ, the research and innovation campus. one of the most important projects is an aviation, the in a normal year,

nearly $14000000.00 sites will weigh each result in heavy c o. 2 emissions searched for an alternative fuel urgent. the one company collaborating with scientist in orkney is 0. obvious, i contact direct to circuit kids who live from is excited about the 1st 15 minute loan hydrogen test flight. to is a combination of almost the 3 years of research. and frankly, it was, uh, it was the zip for delivery and the baby, the frontier was uh sorry. and then the so excited at the same time. i know that you guys are planning to fly here with one of your hydrogen po, claim final flight of our 5 fire one project view be taking place from fortunately that work here is famous for it's being hydrogen. can you give us a time scale when you think that we will see passenger planes in the skype running

on hydrogen? of course the technology is in its infancy, but i personally believe that unit for 15 to 20 years. they will be a lot of jets wines using being 5 isn't and this is true but exciting. so if we can arise to the challenges of energy economy or future transportation needs, it means embracing a range of solutions. and i think for the doing here orkney is proving the green hydrogen to be pot see on the green hydrogen is beginning to take up. it's a key part of the ease plans to come to well 1st carbon neutral constant by 2050, a new projects of being developed and julie cloud, you're right. yes, united states. yes. the rest of the way to guys 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 have a weld free,

a fossil fuels. there is definitely a new power system and a new energy system em are kind of our eyes. 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 constant windshield transition in the energy space that we have seen in the 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 high emission by 2030, it won't be too late to do anything substantial about climate change. this is our last window of opportunity to spend the curve of emissions and get on to a different and trucks. and doing society would be a society that has a 100 percent clean energy. that energy would be decentralized, cheap,

the big switches we would be able to provide power to every single home on this planet. we currently have a 100000000 people who do not have access to power, meaning they're in abject poverty. by moving over to a 100 percent clean energy decentralized, we can make energy big switches 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 the renewable energy generation. sources would also 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 truck would be using clean

seals and finally, city would be clean wyatt because the would have put the internal combustion engine into them and cities would be organized into smaller communities around food and enters at the beginning of the most decisive decade in the history of human kind. this was 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 just after supply of change. and in so doing, we can bring a much better quality of life for oil citizens of this planet. and certainly to the ecosystems upon which we depend. the

people across the planet and spending an increasing amount of time online from what meetings and catching up with friends to move it streaming and shopping. we're now more reliant than ever on platforms which generate and store data. but this data doesn't just vanish. interesting as it comes to the very real environmental cost. everything we do online passes through data centers which consume huge amounts of energy and it meant nearly as much c o 2 as the airline industry. i'm in no way to see how one center is honda, sing the energy of the fuel with to stole our digital information without a heavy comp and footprint. this is the famous tories detraction and photo hot spark plug in store and then 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 imagined with that could be i think the 1st time i would imagine is my one. your asking? i haven't seen the thinking about it. no, i have no idea. i send it to google, i guess in the cloud, in the cloud, and do you know what the cloud is? a big storage place. the night myself, most people only have vague ideas of, well without dates as kit. i've come to university of savannah to meet an expert on the data storage and find out where our associates end up to the photo itself. we just saw you in the memory of the phone. and then if you share the photo or you want to back up the photo into the cloth, it will end up in some data center remotely could be in europe. it could be also in a remote size across the atlantic at both. but you probably have accumulated in

those data center and add those wall ele, uh for us to have a pick up pick the data center. so the, there are 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 curve at 19 pandemic year for the city. so i went online, happy to take a heavy toll on the environment. a typical search which passes through data centers processing and storing information requires as much energy as to do meeting a 60 watt light bulbs. so 17 seconds. that doesn't sound like much until you realize google. a loan process is 3500000000 searches a day. around one percent of electricity globally is consumed by data centers, many of which provide promote storage facilities or what is also known as the cloud

. is estimated that in 10 is that what they to network grows. almost 7 percent of all electricity will be use just to power into huge service per serving everything from 1000000000. so family photos to pick data on space travel. so where and how you store your data can make all the difference. and no way is the head of the game on this, since it's powered nearly a 100 percent by renewable energy, most of which comes from hydro power. i am on my way to venice or an island he asked about not. i've had to have an old military storage, but instead of storing to p, those will hits, they now stole billions of bites of information from over the world. the underground green mountain data center which opened in 2013 is comp and neutral is run on hydropower from water rest of us on the mountains. feel question nice to meet you. nice to meet you as well the

oh wow. it's, it's like being in a james film, but i can see that this is very secure. this is very secure. wow, thank you. so this is how it looked. when we took over the, decides 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 no, we're en freight. 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 in here? it could be anything from storage of pictures to national critical infrastructure.

it could be kids at home doing their lecture online. so many people when they think about the clowns, they think out in the open as i think why. but actually the cloud is ms. talbot and it and it's noisy, it's black and it's noisy, and it comes to a lot of car and generates a lot of heat to see how the center manager says it's a quick write down the corey. oh, the where? the end, if use wrote, this is work for the green energy flows crew into the data. so this is basically the drive in june 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 a city of a 1000000 people. every place you do on your device generates activity inside the data central summer. if it's in norway, screen and renewable as well. so when you're using green energy, this data center is reducing its impact on the environment by tooling it service using cold water from the nearby, deep, thoughtful to inlet of the old. so was most data centers use around 40 percent of the energy to cool service which would otherwise reach a 100 degrees celsius in minutes. this data center gets its cooling free from nature. so this is wherever code using the cold water used to cool the cloud inside. and most cold sea voted from the fuel with anticipation next to the data center. this will say which is constantly 8 degrees celsius,

is then pumped up through the heat. exchanger cooling, found separate water pipes that circulate through the day to fit into the wound up symbol to the exits back into the field at around 20 degrees celsius with quickly close down again. the green mountain data center and no way is unique because of the fuel with cooling the service. and the way in which they've repurposed an old site. but old over scandinavia, tech giants like facebook, google and microsoft building huge data centers running on hydro and wind power. in fact, investment and noting data centers is set to double by 2025. thank you. all work is the phone fully electric. i'm meeting theory kelby, a local matri ologist in green and vista, who's confident this trend will continue. so this is where the hyper power is. yes, the or the flow on a hyper station. it's actually the world's longest $4444.00

steps over a 100 years old. so be careful. so i can see that it's old from this old train here . here you see the, the old pipe coming down from the mountains. so all the was those just flowing high speeds in the pi, creating electricity when they hits the turbine. so you have to use what nature gives you. so in norway we have incredible rain or the country it has sun then. yeah, we also have wind, but here it's rain that's gives us the electricity. scandinavia will be important to the welds data storage. i think scandinavia will be very important for future data storage. it's a cold climate. you can use the cold for your to, to quoted on the data center. we have the hydro power to run data centers. however, i think we also need to be even more responsible and take action that each one of

us. and for instance, if we are talking on both data storage, we need to be concerned about how many solid fees we need to take home many emails on snaps and text message, we need to send so we can 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 world's population is already online and around $1000000.00 new uses sign up each day. as our reliance on the data expands, we need to find green ways to manage it. here in no way, i've seen how this can be done. and i think we really need to learn from examples like this and make sure that we've balance our modern lives with what because china can sustain the which so many of us stuck at home during the times that make it seem perhaps hard to see that the world

really has been given a golden opportunity for creating recovery commitments are happening all over the place as nations businesses, cities, investors connection that 0 kaufman's hall gets by 2050. but right now 25. she's the key. yeah. that's just under thanks to time and the feature of the planets around the world already seemed glimpses the green society, the could be ours, no stair renewables. i would say fossil fuels as a main source of electricity in europe. a new case in australia is, is a solar panels on rooftops, one in full hines, the noah was of that sort of complex america. so, i mean, it's fast phase and it's already producing enough energy to power. the city of mara cash twice that 60 percent of monthly cost cells in no way. oh electric diesel costs will be banned, veterans funds, twin size. the solutions are full ready that they just need to go global to make a real difference for us to have that shows that exceed green and prosperous speak

. check the russell bid in southern england with 2 farmers trans safari park. pioneers fits the attractive nature in the driving seat. i was just absolutely astonishing. the license pulled back even not sorry for somebody. and i am again sophie, i sent you over to me when one volume your income funding is revolutionizing. this was the same using funds in our 57th images. here inside, you have science. you have a technology, the fries phone out, your 0 the,
