it's the government has imposed a nightclub, a few on the indian ocean islands ahead of a visit by president emanuel my crone. it's 5th, the final death toll could be in the hundreds. lots of sweeping through miles. cycling chito continued west to malawi and mozambique with 34 people have died and several others has been injured. the u. n says thousands of and left without shelter, the water and food of the homes. the schools and health facilities were partially or completely destroyed. at least 14 people have been killed and hundreds injured. after a $7.00 magnitude of quake struck the south pacific island nation of federal law to alexander bias reports. a disaster strikes value out to this is the moment, the 7.3 magnitude earthquake, exploded deep under water near the coast of the capital port v last one of the most

powerful quakes to hit the region in decades. it's a stronger quick than i've ever experienced in my 21 years living in vine, walter, and i seen quite a few and quite a few large ones. my wife said it was the largest one she had seen in her life. i assure you, of course, is born and bundle are true. at least 6 aftershocks followed the initial quake, which flashes buildings throughout the city. like this one, housing, the american, british, and french embassies. all staff are safe and accounted for. but communications are down in power and water caught in most of the capital roads to the port destroyed by land slides with the hospital to damage to function. injured people are being treated outside nearby australia is deploying emergency teams to help. we will provide whatever assistance is required. i'd say i say to the people have been

a while to your family and australia is here to help donna watts who lives within the pacific ring of fire. and 1st quakes are common here. un says more than 100000 people have been affected by this one. witnesses report bodies laying in the streets as rescuers work to help survivors and find those missing. the death toll is expected to rise. alexandra buyers al jazeera as well. that's the news. so now i'm jessica washington. you can find more information as always on our website, our sierra dot com. the news continues here on how to 0 off to us. right. and then terry jones be here with 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 of the color. and the 1st of a 2 part investigation, one. 0, one 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 off to a revolution. the carpet, 19 cons. demik is accelerating. i'll move away from fossil fuels as price tags of renewables, particularly solar, comes down. it is now possible to actually imagine a call but mutual well to run on clean energy. but there is still

a long way to guys climate change this account longer, 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 life a woman. 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 to power a 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 for a while. renewable energy for when the sun, the seas cheaper than ever into mrs. difficult to store

a few of the future is emerging, which could prove fundamental to de carbon ice and the global economy. i've come to the orkney islands of the north coast of the u. k, where a network of sizes and 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 buses and even spacecraft. 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 oregon, 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 deal who's a hydrogen project manager and was brought up for an organ. just let me know maryland. we have this sense of self sufficiency. we need to do things for our sales practice to not really community. 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 m 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 outside. what's the connection between when 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 that 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 uses the energy from the wind turbine exploits for each to oh, well sure into the hydrogen and oxygen. we talked to the hydrogen for you for energy . and the option of the moment is just right spirit. so you're re diverting. yeah. that when delta dental hygiene, that's right. yeah. as 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 it's original density. that's a lot of energy. i'm meeting with james ferguson, a specialist in hydrogen storage. the highly assemble 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 you want to store a lot of energy over months. so we know that 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 the island was completely silent. it all completely silence. 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, 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 the 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 water bases here.

yeah. right. all right, really, thank you. so that was presented to me, it's great to hear how it seems to be going all the time. and there's it 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 operates 74 different connections and they are more than 20000 sailings each year with fuel use and shipping by the polluting. david for david hitt, who works with a company create hydrogen is part of this plan to clean up c authoration. and they all happens below that. i have no idea what we're getting to here, but here we go. the shift

towards using hydrogen is system engine surprises, eating 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. i contact direct to surrogate 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 a, it was a zoo for delivering the baby and the phone. she was 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 flights 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 in about 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 what they're 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 wealth, thus comp and mutual confidence by 2050 new projects of being developed and julie cloud, you're right. yes, united states. yes. the rest of the way to guys before green hodges in 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 wealth free of 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 a 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 will be too late to do anything substantial about climate change. this is our last window of opportunity to spend. it's a curb of emissions and get on to a different and track and doing society would be a society that has a 100 percent clean energy. that energy would be decentralized, cheap,

the big switching. 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 switches and we can bring those work 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 time 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 entrance 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. think the energy of these fuel with to stole our digital information without a heavy comp and footprints? this is the famous tourist attraction and photo hot spark plug is stored 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 imagine 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 data storage and find out where our associates end up to the photo itself. we just saw 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. so you probably have accumulated in

those data center and add those wall ele, uh for us, for have a pick up, pick the data center. so the, there are problem for sustainability. how long? how much data we have to spoil 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 lightbulb for 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 and to huge service pacific, everything from philly and 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 near as development. 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. so question nice to meet

you. nice to meet you as well the oh wow. this is 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 know 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 white and fluffy. 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 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 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, it's green and renewable as well, so new using green energy, this data center is reducing its impact on the environment by cooling it service, using cold water from the nearby, deep, thoughtful to inlet of the old. so whilst 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 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 notice 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 slowing high speeds in the pi, creating it electricity when it 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 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 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 to take action that each one of us

. and for instance, if we're 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 some 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 supreme 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 connection that 0 kaufman's hall gets by 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 who already seemed glimpses the green society, the could be hours, you know, stare, 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 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 cash twice that 60 percent of monthly cost cells in no way are electric. diesel costs will be found veterans punched twin size. the solutions are full ready that they just need to go global to make a real difference for us to have that jones that exceed green and prosperous speak

. sure. the lines of ethnic i'm groups is posing the biggest challenge to me in most contest since the 2021 with the exclusive access to remote camps and find find battles, shouts. the progress of an idealistic young generation of rebels is a pivotal moment in the last 60 years of the country's trouble history. on the phones being ma, on the, on the ropes on al jazeera, the latest news as it breaks the last test. what was the place of the tower of president bush chart? and i said his room is now over with detailed coverage. don't mom on his part to one to process the winning facebook for this funny wordpress to the faithful. the
