being days, daring, and intriguing, some will admire that others will find it pointless, but increase those world, creating the unnecessary with the ultimate expression of freedom. natasha butler. i'll just sarah paris. finally, broadway is properly back in business in new york theatres. once again, allowed to fill 2 capacity for the 1st time since the pandemic brought curtains down the lion king hamilton and wicked, our course among the 1st to open to a full house and 30 more shows, shows you to follow by the end of the year. ah, it is good. tell you, but the fellow adrian said, again, here in the headlines on, i was just here are the us secretary of state and to the blinking. let's face the 2nd. they have tough questioning. over the heavily criticized withdraw and evacuation from afghanistan, he told the senate foreign relations committee that the rapid collapse of the

african army was unexpected. and they're looking into why intelligence agencies fail to see it coming. we need to look back at all of this because to your point, we collectively over 20 years invested discretionary amounts in those security forces in, in that government, hundreds of billions of dollars, equipment, training advice support. and based on that, as well as based on what we were looking at real time again, we did not see this collapse in a matter of 11 days. the taliban has thanked international donors for the a money pledge to the un conference on monday. at a news conference, the acting foreign minister emphasized the groups intention to distribute the aid to every african who needs it. and he asked more countries and donors to consider sending help. president prisoners hosted his syrian allied bash last out in moscow

as the 1st time they've met since early last year, they discussed how that forces will gain control of serious last rebel held areas. guineas military chiefs, a meeting political and religious leaders to discuss a transitional government. following last week's qu, special forces seized power and arrested long time president of a condi on september 5th. a trial in ramallah for 14 palestinian authority, security officers who are accused of being an activist to death has been adjourned . his arm bandit died in june to be arrested at home that led to demonstrations across the occupied westbank. apple has released software to fix a security flaw that allowed hackers to infect i, phones and other devices without a single click from users, such as say, they capture the malicious code from pegasus spyware, made by the israeli company, and s o group. it was used to hack the phone of a saudi arabian activist, others the headlights and he continues to 0 to us. why as change of power

me ah ah, ah, me are in the middle of the biggest energy transition, some industrial revolution. the cobra 1900 pounds, amec is excel rates and i'll move away from fossil fuel price tax of renewables,

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

impact for life on earth. renewable energy from when sun and sea cheaper than ever intermittent, it's difficult to store. a few of the future is emerging, which could prove fundamental to de carbonite, the global economy of come to the orkney islands of the north coast of the u. k. where a network of scientists and researches approving the missing link in the next renewable energy revolution might be found in the simplest and most abundant elements. hydrogen, the universe is about 73 percent hydrogen mainly occurring as gas, but on earth most hydrogen is contained in water is the h in h 2 after it's generated from water can be used as a few post cause buses and even spacecraft. but in order to extract it from water, you need electricity. when that's produced using fossil fuse,

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 and title turbines. it could be a game changer. ah, a meeting, a del lydia dale who's a hydrogen project manager and was brought up on orkney. just let me know if we have a sense of self should be we need to do thanks for our sales doctor for we cannot really get in touch on island community. we come to shop and say when a board 13 and have a good islands to see how they produce. i just kind of a joke to possession of small, quiet island for quite a high energy for this turbine is owned by local residents and produces more energy than the local grid can handle. the excess power is used in hydrogen production. i'm no scientist, but i could see on the it says, explosive,

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

as storing and storing the high it's transported by trailer and he's all over orkney, some in domestic heating but mostly in commercial vehicles and ferries. in the trailers, the hydrogen stored under pressure at $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 side. oh wow. oh gosh, so one of the big advantages of hydrogen is that it is a kind of option for seasonal energy storage. and that's when we want to store a lot of energy over months. so we know that in the u. k. during the winter, it's very blue, it's very windy. if we go to a wind turbine based energy system, we're going to have a lot more generated in the winter than we need. and so we can capture that and store it from the form of hydrogen,

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

completely silent. wow. you can sometimes hear the compressor from the hydrogen when it's when it kicks in. it, you know, here we, well, that's all you know here. david hannon is working with the council to expand its use of hydrogen technology. so for a long time, we're talking about electric vehicles as being the future of, of green transportation. what do you get a hydrogen per vehicle that you wouldn't get of an electric vehicle? this is also about 3 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 lot range and is another advantage. it's quick to refill with electric battery. you might take from half an r to it ours to charge your battery, whereas this is pretty much instantaneous, you know, talking couple of minutes normally we'd expect to see an exhaust pick that the back of eventually this. yeah. and you can see there's no exhaust here,

i mean same as any other electric vehicle. obviously we've got hydrogen, but then the sort of emissions off out as water paper is here yet. right? wow. all right, really just with, with me, it's great to hear house seems to be growing all the time. and there's that awareness of the importance of this kind of network or there's a quality of energy when you live in an archipelago. another important form of transport is very nice, very company operates 74 different connections and there are more than 20000 sailings each year. but the fuel used in shipping badly polluting i, david for david, hidden who works with the f. a company in green, hydrogen is part of the plan to clean up the operation. and they all happens below deck. ok.

have no idea what we get into it, but here we go. oh wow. oh the ship. what we looking at him. the cylinders contain site looks like that's the 20 leadership fuel. what are you using? the hydrogen? hydrogen, i still want to invest system will run on a salary generated engine light steering safety systems and the, the lights and everything and the so when in the future, hydrogen will be used to drive all ships, operations, including propulsion within the stopping is the smallest built ship in the states that already established fans and ferries powered by green hydrogen just part of the picture in orkney. pioneering research into how the fuel could play a global role in transport. and beyond is happening here at the orkney research and

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

place from for can you or can you use famous for it, the hydrogen? can you give us a time schedule of when you think that we will see passenger planes in the sky running on hydrogen? of course the technologies in its infancy. but i personally believe that 15 to 20 years, they will be a law. the death wind using hydrogen, and this is truly exciting. so we're going to rise to the challenges of our energy economy, our future transportation needs. it means embracing a range of solutions. and i think what they're doing here orkney is proving the green hydrogen part. the green hydrogen is beginning to take home. it's a key part of the ease, the well 1st carbon neutral constant by 2050, a new projects being developed in chile, saudi arabia, the united states. yes,

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

a society that has one re percent clean energy. that energy would be centralized, cheap, ubiquitous. we would be able to provide power to every single home on this planet. we currently have 800000000 people who do not have the power, meaning they're in abject poverty. by moving over to a 100 percent clean energy d centralized. we can make energy, the big picture, 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 renewable energy generation sources. with all of the 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 field. and finally did. he would be clean wyatt because he would have put the internal combustion engine into them and that he would be organized into smaller communities, around food and energy at the beginning of the most just science the decade in the history of human kind. it will 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 the climate change, and in so doing, we can bring a much better quality of life for all citizens of this planet. and certainly to the

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

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

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

a day. around one percent of electricity globally is consumed by data centers, many of which provide remote storage facilities or what is also known as the cloud is estimated that in 10 years this our data network grows. almost 7 percent of all electricity will be used just to power and qu huge service, preserving everything from billions of family photos to big data on face travel. so where and how you stole your data can make all the difference. and no way is ahead of the game on this since it's powered nearly a 100 percent by renewable energy, most of which comes from hydropower. i'm on my way to an island near. i've had to have an old military storage, but instead of storing 2 kito hits, they now stole billions of bites of information over the world. the underground green mountain data center which opened in 2013 it's carbon neutral. it's running

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

equipment. so what kind of information if don't hear it could be anything from storage, your picture to national critical infrastructure. if you'd be kid at home doing their lecture online, so many people when they think about the clouds, they think out in the open as their thing, white and fluffy. but actually the cloud is ms tally and it and it's noisy, it's black and it's noisy, and it consumes a lot of power and generates a lot of heath to see how the center manager says it's a quick write down the oh. where in the future road, this is where all the green energy flows through into the data. so this is basically the giant engine of this data center. the consumption in this data center

with all the different data holes at consumes the power equal to about 20000 household. while this may seem a lot, some of the biggest data centers, consumers, much power. as the city of a 1000000 people, every click you do on your device, generate at humidity in 5 data center, summer. if it's in norway, it's green and renewable as well. so only using green energy. this data center is reducing its impact on the environment by tooling its service using cold water from the nearby deep salt water inlet of yard. so whilst most data centers youth around 40 percent of their energy to cool servers, which would otherwise reach a 100 degrees celsius in minutes, this data center get to cooling free from nature. so if it were producing the cold water use to cool the cloud, a 5 ammonia cold sea water from the fuel into the basin next to the data

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

it's actually the world's longest 4444 stepped over a 100 years old. so be careful, though i can see that it's old from this old train here. here you see the old pipe coming down from the mountain. so all the water's just flowing high speed in the pi, creating electricity when they hit the turbine. so you have to use what nature gives you. so in norway we have incredible rain or the concrete have sun then. yeah, we also have wind, but here it's rain that gives us the electricity. scandinavia will be important to the world's data storage. i think scandinavia will be very important for future data storage. it's a cold climate if you can use the cold fjords to cool down the data center. we have

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

time during the plans that make it perhaps hard to see that the world really has been given a golden opportunity for green recovery commitments are happening all over the place as nations businesses, cities, investors pledge 0 carbon targets by 2015. but right now 2030 is the key. yeah. that's just under a decade determine the future of the planet around the world who already think glimpses the green society, the could be our last year, renewables over to fossil fuels as a main source of electricity in europe, a new case in australia, the solar panels on rooftop the one in for hi me. the know was that photo complex and morocco studying its 1st phase. and it's already producing enough energy to power the city of my ra, cash, twice. a 60 percent of month the car sells and no way or diesel cars will be banned there in 2025. the solutions that already that they just need to go global make

a real difference ought to have shown that the clean green and prosperous future. ah ah ah ah ah, most people will never know what's beyond the stone, the deafening silence of 100000 how it feels to touch danger every day. most people will never know what it's like to

work with. every breath is pressure with fear is not an option. but when most people oh be the hero, world needs. ah, washing in the the american people want to know who is responsible for this. you are a secretary of state anthony pen can face as a 2nd day of questioning about the way the african withdrawal and evacuation were handled. that emergency evacuation was sparked by the collapse of the security forces and government ah.
