but that's decline is that what we're seeing here is proof that we can reverse that trend and we're not doing it in the world in this environment. we doing it right in the middle of a study in this eco century, the birds and metrics all safe from introduced purposes. it's surrounded by an almost 2 meter high fence stretching for nearly 9 kilometers. in 25 years, there will be just full ink cushions. birds act hurley sites in the same tree that fits this incredibly affective. it's a place for them to thrive in the house of the city, but some is no longer completely drowned out by the drone of traffic that's possibly down to people like n e h. one of hundreds of volunteers supporting and ambitious campaign to make new zealand primitive, free by 2050 the hills about the capital. one of the target areas. she's

seeing results a server as we used to catch 5, right? so we now we lucky enough to catching the may be one a month and say those numbers are free really dipped. and from that, we're seeing this that the populations increase for the con, paid to succeed, will require the eradication of thousands more rugs stokes possums and weasels creatures plus brought to new zealand by european unplugged agent settlers. it's a controversial strategy, but one, many conservationists defend. we have seen foods ripped apart by ritz and by starts and fig. smashed by pulse them. humans are doing enough damage. the predators is, it's just, you know, same thing out that the family says something has changed. yeah, type. it has changed for an easy lens. national but the flight let's keep a closer off to being re introduced 2 years ago. the key we is now breeding in

these hills for the 1st time in living memory. new zealand responsive. both power dies because they would know land credit is one of those islands that have evolved separately from the rest of the world. and we have actually unique animals here. and most famous levels are key we, it's what we're known is overseas. it's a really critical part of our identity as people he hopes these hills could again become what they once was a natural but century adrian brown, al jazeera weddington protecting using his natural well. and that's it for me, mccloud plenty more. of course website i'll just or dot com is the address. plenty more news coming up with 0 right off to uprise. i'll see you soon by 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 fast of a 2 parts investigation. 101 east meets the chinese, my friends. risk middle to the american dream on out to 0. the for in the middle of the biggest energy transition sustained, also revolution. the carpet 19 content mckissick celebrates now move away from fossil fuels of price tax of renewables, particularly solar come down. it is not possible to actually imagine a company actual, well to run on clean energy, but there is still

a long way to guys climate change as to how long it takes less time. so that still states, we must talk global greenhouse gas emissions by 2013 before to have any height of reach and that 0 by 2050 and avoiding the west effects of light but will make so 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 working with one a clean energy is holy grails, green hydrogen. and in no way a cub mutual date of sensor 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 light, for a while. renewable energy for wind, the cheaper than ever into mrs. difficult to store a few of the future is

a mode things 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 d h in h to go after it's generated from water. it can be used as a fuel depos cause the buses and even space craft. 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 adel lydia, do 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 practice and we are not pretty cuz 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 shut off small, quiet 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 the hydrogen production. i'm no scientist, but i could see on that the, the sign that says and explosive compress gas. and what is actually happening

behind these display? it's what's going on in these boxes were for working energy production sites on either side. 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. 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 will sure enter hydrogen and oxygen. he talks through the hydrogen for use for energy. and the option at the moment is just straight at top spear, so your re diverting. yeah. that when the d dental hygiene office, right? yeah. storing and storing hard when it's transported by trailer and used all over or some in domestic heating but mostly in commercial vehicles. and ferries,

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. 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 the in the u. k during the winter is 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 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 mills. so what it shows me how to produce hydrogen with a many electrolytes. so we just to wait a moment, we're going to generate some hydrogen. we're going to get a build up an electric current passing through the water forms. hydrogen mobile 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 the cargo. that is absolutely good. is that something better catching on? the principle, the pose, the fuel cell in james's toy car is the same when scaled up to power a fleet fight. cancel. events on the island was completely silent. it's 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 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 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 water bases here.

yeah. right. all right, really thank you. said with results 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 this ecology of energy when you live in an archipelago. another important form of transport is very often the ferry company of rates, 74 different connections, and there are more than 20000 sailings each year with the fuel use and shipping is badly polluting. david for david hitt, who works with the fake company create hydrogen is part of this plan to clean up. see on the ration and they all happens below that. i have no idea what we get into here, but here we go. oh wow. the ship

the southern destin t 20. using this hydrogen is doing the best system. and it tells me to speak to the 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 orkney 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 search a case of live since excited about the 1st 15 minute loan hydrogen test flight to is a combination of almost the 3 years of research. and that, frankly, it was the, it was due for delivering the baby and the funky was so really 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 slide, the power fi fire one project feels 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, there will be a lot of debts, winds using green hydrogen. and this is truly 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 part. see on the green hydrogen is beginning to take off. it's a key punch, the ease plans to come to well 1st carbon neutral constant by 2050, a new project. so being develops into 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 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 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 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,

big, which we would be able to provide our 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 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 trends would be using clean seals

and finally, city would be clean wyatt because we 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 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 are 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 emit 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 the heavy comp and footprints. 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 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 cloud is. ready of a storage place like myself, most people only have vague ideas of where 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 year for the study. so that 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 in 10 is a solid data network grows almost 7 percent of all electricity will be used just to power and to huge serve as preserving 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 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 2 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 and hide to power from both the 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 servers, storage equipment. so what kind of information is going on 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 clouds, they think out in the open as their thing, white and roughly. but actually the cloud is ms tally and it and it's noisy, it's black and it's noisy, and it comes to a lot of car and generate a lot of heat to see how the center manager says it's a quick write down corey. oh, the where? the end, if use wrote, this is where all the green energy flows through into the data. all. so this is basically the drive in june of this data center, the consumption in this data center with all the different data holes and 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 cooling its service, choosing cold water from the nearby deep salt water 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 wind 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 were 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 on a hyper station. it's actually the world's longest 4444.

that's 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, the old pipe coming down from the mountains. so all the was those just slowing high speeds in the pi, creating it 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 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 services 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 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 china can sustain the which so many of us stuck at home during the plans 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 coffins 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 last year, 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 banned veterans, $1.00 to $25.00. the solutions are full ready that they just need to go global to make a real difference for us to have that chose 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 us so much. and i'm again sophie, i sent you over to me when one volume your income funding revolution. i seem to put the same funds in. are you sending the images here inside? you have science, you have a technology, the fries phone out, your 0 the,
