jewish note any affectively abolishes the right to demonstrate power will test. sorry for some of the wonder. now rosa and today is 5 years old. her brother adolfo, is 3. the drawing on top is also a family window altogether. the one below is of the father. he is in jail, for protesting against the goal is the government. the mother gets the children to write to him every week. she says her husband is sick and is sometimes denied medical care. i tried not to find because for you to see your husband in that situation, it's very painful. some samuel things thinking like a crying because this too much, but he felt so much pain and you cannot do nothing. or you'll have the right people to do something for them, but they don't leasing them. okay. rights groups describing goal is government as repressive. similar to or she me, we have to turn around is you know,

that does not respect human. right? that's good for being a preist. these no freedom of assembly, no press, freedom of detroit arrest and government critics. a silenced it's an accusation that's not a to deny. the government also sees peoples of property, participate in the gathering and not use protests accounts and violence. i'll see to myself the allegations made by just as if it's not true, our going toppling respects human rights and democracy my according to the law and constitution, they are human rights. and nicola, is the presidential decrees that the rest gets to the city. and goal is using the legal system to cut down on projects over the politicians in this building. and by the past will try to introduce legislation to advise groups. they failed to meet international human rights standards and restrict freedom of expression. some of

these laws in people's, in terms of up to 25 years for people who participate in purchase that result in vandalism, and disrupt services and goal as the trying to rebuild is reputation. since 27 years of civil war came to an end in 2002, the country is an important trading partner for china and the united states. but that's of a say. they also want the international community to pay more attention to human rights. had them with us out to their lender more and all the stories we're covering on our website that alger 0 dot com stay with us for a size next. thank you for watching the . the record numbers of chinese asylum seekers are traveling to the us. that's double many take a dangerous route through loss in america. a gang of people points that are coming in the 1st of a 2 part investigation, 11 east meets the chinese,

my friends risk and you know, the american dream on out to 0. the, for in the middle of the biggest energy transition sustained us to revolution. the carpet 19 content, mac is accelerates, and i'll move away from fossil fuels of price types of renewables, particularly solar, comes down. it is now possible to actually imagine a call, but unusual. well, to run on clean energy, but there is still a long white sky climate change as a guy with the markets thing this time. so that's to say, we must talk global greenhouse gas emissions by 2013. if were to have any height of

reaching that 0 by 2050, and avoiding the west effects of global warming. so the change while it is happening, needs to happen quicker. and this program will be look 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 working with one of clean energy, is holy grails, green, hydrogen, and in no way a comp and mutual data sensor is using the force of nature, 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 impacts for life. for a while, renewable energy for when the sun, the seeds cheaper than ever in submissive, 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 earth most hydrogen is contained in water is the h in h to go after it's generated from water, it can be used as a fuel it pose, cause the buses and even space craft, but in order to extract it from water, 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 adel lydia deal,

who's a hydrogen project manager and was brought up on what can we help this sense of self sufficiency? we need to do things for our sales community. we come to shop and say when the board is 13 and have it to 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 m explosive, compress gas. and what is actually happening behind these display, it's what's going on. and these boxes were for working energy production sites on either side. 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. it splits for each to oval. sure into the hydrogen and oxygen. he talks through the hydrogen for use for energy. an option at the moment is just straight. it's often spear, so your re diverting. yeah. that when delta dental hygiene, right? yeah. a storing and storing hyphen it's transported by trailer and used all over or some in domestic heating. but most of the commercial vehicles and series in the trailers, the hydrogen is stored under pressure at a $184.00 times it's 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 that us. 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 is very blue. it's very wendy. 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 electrolytes. so we just to wait a moment, we're going to generate some type of thing. we're going to get a buildup of electric current passing through the water forms hydrogen mobile. there's another 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 the cargo. 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 a fleet fight. cancel. events on the island was completely silent. are 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 counselor 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? 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 battery, 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 the van like this. yeah. and, and you can see there's no source here and the same as any over electric vehicle. obviously we have a 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 was presented to 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 there's a quality of energy when you live in an archipelago. another important form of transport is very often these very company operate 74 different connections and they are more than 20000 sailings each year with the fuel use and shipping badly polluting david for david hitt who works with the fake company create hydrogen is part of this plan to clean up the ration and they all happens below that. i have no idea what we're getting to here, but here we go. oh wow. the ship the southern does contain 20. using

hydrogen is still in the system. it's quite speeding safety systems and the delay in the future. hydrogen used to ship the 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 isn't aviation the in a normal year, nearly 14000000 sites will result in heavy c o. 2 emissions searched for an alternative fuel urgent. the one company collaborating with

scientist in orkney is 0. have you contact direct to survey case of live since excited about the 1st 15 minute loan hydrogen test plate to is a combination of almost the 3 years of research. and frankly, it was the, it was the zip for delivery and the baby, the funky, was the 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, clean the final flight, the power fi, fire one, project view be taking place from fortunately that work here is famous for its being hydrogen. can you give us a time scale of when you think that we will see passenger planes in the skype running on hydrogen? of course the other 2 using its input and see, but i personally believe that unit for 15 to 20 years. they will be

a lot of jets wines using green hydrogen and this is true but exciting the so if we can arise to the. 6 changes 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 off. it's a key part of the ease times to come to well 1st carbon neutral constant by 2050 new projects of being developed. and julie styled your radius 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 in 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 half emission by 2030, it will be too late to do anything substantial about climate change. this is our last window of opportunity to spend the curve of admissions and get on to a different and try and do means to science. new would be a society that has a 100 percent clean energy. that energy would be the central line, cheap, big quickness. we would be able to provide power to every single home on this

planet. we currently have 800000000 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, which is, 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 trans would be using clean feels. and finally, city would be clean wyatt because we would have split 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 asked is the time 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 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 with a very real environmental cost. everything we do online passes through data centers which consume huge amounts of energy and emit nearly as much c o 2 a c as in industry. i'm in no way to see how one center is honda thing, the energy of the fuel with to stole our digital information without a heavy comp and footprint. this is the same as torres detraction and photo hotspot poker 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 sophie, it lands somewhere, have you ever imagined with that could be i think the 1st time i would imagine it's

not when you're 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 child is? a big storage place. like 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 the remote site across the atlantic at both. so you probably are accumulated in those data center and those will force us to have

a pick up pick the data center. so the, there are problem for sustainability. how long? how much of 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 of 19 pandemic. here for the city, so that i went online habits take a heavy toll on the environment. a typical search which passes through the data centers processing and storing information requires as much energy as a new meeting, a 60 watt light bulb for 17 seconds. that doesn't sound like much until you realize google. a loan process is $3500000000.00 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 intent is to start with data network grows almost 7 percent of all electricity will be used just to power into huge service per serving everything

from billions of 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 hydropower. i'm 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 wall 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. so question nice to meet you. nice to meet you as well the 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. 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 know we're en freight. what people refer to as the cloud. this is where our customers are running their servers, 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 cloud, they think out in the open as i think why the 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 cord. oh. where the end, if use, wrote this work for the great an energy flows through into the data. all. so this is basically the drive engine of this data center, the consumption in this data center with all the different data holes that 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 place you do on your device,

generates activity inside the data central summer. if it's in norway, screen and renewable as well. so in a using green energy, this data center is reducing its impact on the environment by cooling it service, choosing cold water from the nearby deep salt water 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 down, separate water pipes that circulate through the day to fit into the wall and up symbol to the exits back into the field at around 20 degrees celsius with quickly

close down again to the green mountain data center and no way is unique because of the fuel 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, notice data centers is set to double by 2025. thank you all work is the phone fully electric. i'm meeting see re kelby a local matri ologist in green and vista who's confident this trend will continue. so this is where the hydro power is. yes, the or the flow may high for station, it's actually the world's longest 4444 step over a 100 years old. so be careful. so i can see that it's old from this old trading here. here you see the old pies coming down from the mountains. so all the

was those just slowing high speeds in the pi, creating electricity when they hit 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 gives us the electricity. scandinavia will be important. so the welds data storage, i think scandinavia will be very important for future data storage. it's a cold climate, you can use the code 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 to take action each one of us. and for instance, if we're talking on both data storage, we need to be concerned about how many services we need to take home. many emails

on snaps and text message. we need to, sam though 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 in 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 scientists can sustain the which so many of us stuck at home during the plans that make it stream. perhaps hard to see that the world really has been given a golden opportunity for reading recovery commitments are happening all over the place. as nations businesses, cities, investors pledge that 0 call been target slide 2050. but right now 25. she's the

key. yeah. that's just on to a tech, to determine the feature of the planets around the world already seemed glimpses the green society, the could be hours last year, renewables. i would say fossil fuels as a main source of electricity in europe. a new case in australia to the solar panels on rooftops, one in full hines, the nor 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 catch twice that 60 percent of monthly cost cells in no way are electric. diesel costs will be found there in 2025. the solutions are full ready that they just need to go global to make a real difference for us to have that shown as a clean green and prosperous speak. check the
