green parties are on the rise in france and climate change is expected to be a key issue in next year's presidential election the sense among many environmental campaigners though is the mackerel this missed a chance to win their support. al-jazeera western france and you can find out much more on that and everything else that we've been covering on our website al-jazeera dot com. and now the top stories on al-jazeera more than 3 150000 coronavirus cases in almost 3 and a half 1000 deaths have been reported in india the government says cases are beginning to go down but testing has also dropped the opposition is calling on prime minister modi to impose a national lockdown the government is also facing a backlash for pushing on with infrastructure projects despite the health crisis

continuing. the lawyer for former u.s. police officer derek show that has filed a motion requesting a new trial citing multiple grounds including jury misconduct last month chauvin was convicted of 2nd and 3rd degree murder as well as manslaughter for the killing of black man george floyd it's been 6 months since ethiopia's government began an offensive in the northern tier gray region more than $60000.00 refugees have fled to neighboring sudan surgeon that there would last a fair is one of thousands displaced by ethnic violence since the beginning of the conflict he says the violence particularly against women is escalating. it's getting more worse in the beginning it was. the killing that subsequently the torch has we're getting more grapes there are women who've been raped some of them have come and some of them were brave enough to come in the pot so this accounts of

rapes are very very huge particularly in a place that we were in the same in order to grab the killing is continued. international experts are being called to mexico city to investigate the collapse of an overpass that calls the metro train to plunge onto the road below killing at least 24 people cranes have been lowering the carriages after monday night's accident the crash has raised safety questions about one of the world's busiest metro systems mexico's president of the us find a way lopez obrador has promised a swift investigation and that nothing should be hidden from the public and that is it for now earthrise a change of power is next looking at possible solutions for a carbon neutral world and my colleagues in though i will have more news in half an hour thanks for watching but i. in 19054 young angie apartheid activists were

murdered by south african security forces if you can't solve the problem by the moving the guy then you could get 36 years on a family's quest for justice reveal systemic resistance to prosecution in musselburgh conflict. and exposes the influence the former apartheid establishment still wielded in the new south africa my father died for this people in our investigation on al-jazeera. or in the middle of the biggest energy transition since the industrial revolution because in 1900 m.

it is accelerating our move away from fossil fuels as price tags of renewables particularly solar come down it is now possible to actually imagine a carbon neutral world run on clean energy but there is still a long way to go. climate change as a care what the markets think the science will but still say we must have global greenhouse gas emissions by 2034 to have any hope of reaching that 0 by 2050 and avoiding the worst effects of global warming. so the change while it is happening needs to happen quicker. and this program will be look it's who of the solutions that have a part to play in that transformation on the orkney islands in the u.k. scientists are working with one of clean energy is holy grails green hydrogen and in no way a carbon neutral data center is using the force of nature to power our digital lives. the global demand for energy is increasing but burning fossil fuels is polluting and it's warming the

planet with devastating impacts for life on earth while renewable energy from wind sun and c cheaper than ever but intermittent it's difficult to store. but a few of the future is emerging which could prove fundamental to decarbonise in the global economy i've come to the orkney islands off the north coast of the u.k. where a network of scientists and researches approving a missing link in the next renewable energy revolution might be found in the simplest and most abundant element hydrogen. the universe is about 73 percent hydrogen mainly occurring as gas but on earth most hydrogen is contained in water it's the age in age to go after it's generated from water it can be used as a fuel it poses cause. buses and even spacecraft but in order to

extract it from water you need electricity and when that's produced using fossil fuels it contributes to greenhouse gas emissions in orkney known as the energy islands scientists have discovered how to produce green hydrogen using green you will pose generated by wind farms and title turbines it could be a game changer. a meeting indelible deal who's a hydrogen project manager and was brought up on orkney just living on the island we have a sense of self-sufficiency we need to do things ourselves you can't just a week arriving and not really have something resilient as an island community we've come to shop and say one of the 13 inhabited islands to see how they produce hydrogen it's kind of a juxtaposition of small my island or my high tech energy project. 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 this. explosive compressed gas. what is actually happening behind these misfits what's going on in these boxes so if i'm working in energy production sites which is why we're standing at site what's the connection between when that hydrogen we have the wind turbine going round here today when it reaches a fair and we're 2nd we switch that energy production over to produce hydrogen. these metal boxes contain the key piece of machinery and electrolyzer the generates hydrogen gas and electric current flows through the electrolyzer causing water to break down into hydrogen and oxygen hydrogen is then collected and compressed so the election i just takes normal drinking or it uses the energy from the wind turbine that splits each 2 will water into hydrogen and oxygen. we capture the hydrogen for use for energy and oxygen at the moment it's just rain at the top of

the spear so you're really diverting that wind energy into hydrogen yet as storing and story night and. it's transported by trailer and used all over orkney some in domestic heating but mostly in commercial vehicles and ferries in the trailers the hydrogen stored under pressure 184 times its original density that's a lot of energy a meeting with james ferguson a specialist in hydrogen storage the highly inflammable gases locked away incompetence on the key site. oh well. so one of the big advantages of hydrogen is that it's 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 is very low 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 in 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. so how is hydrogen used as a fuel. well james has a rather not a way of demonstrating with a toy car that looks about what that's about 20000000. issues we have to produce hydrogen with many electrolytes so we just wait a moment we're going to generate some hydrogen we're going to get a build up and electric current passing through the water forms hydrogen bubble some gas storage here that we didn't have for so long going to take my cables around here and you can see you know the gases are flowing into the fuel cell and then that's going to allow us. to tea with me it's a cargo that is absolutely right this is yeah that's sort of better calculate. the principle that posed the fuel cell in james's toy car is the same when scaled

up to post a fleet 5 council so on the island well it's completely silent. open while you can sometimes hear the compressor from the hydrogen when it's when the it kicks in and you know here we. are here david hannan 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 cute true green transportation what do you get a hydrogen powered vehicle that you wouldn't get an electric vehicle. also about 3 runs out. but then the hydrogen is your basic standard so if you're traveling long distances you can potentially double that range and there's another advantage it's quick to refuel with. you might take from an artsy the charger battery whereas this is pretty much instantaneous you know talking couple of minutes. normally we'd expect to see an exhaust stick at the back of

a van like this yeah and you can see there's no exhaust here everything with any of or electric vehicle obviously we've got hydrogen but then me as sort of emissions of water vapor it's water vapor right. all right really. whispers off disney it's great to hear. things to be growing all the time and there's an awareness of the importance of this kind of network or this ecology of energies. when you live in an archipelago another important form of transport is the ferry orkney ferry company operates 74 different connections and there are more than 20000 sailings each year with the fuel used in shipping it's badly polluting. for david who works with the freight company create hydrogen is part of his client to clean up the operation. and it all happens.

ok. i have no idea what we get into here but here we go. oh well fellows this year. what we're looking at here the cylinders continue fighting kilos of hydrogen us economy 20 leadership fuel but he uses this hydrogen hydrogen is still wondering just system it will run on a road so legionary an engine and it's only due to the engine supply stealing the 60 systems and the delays in getting a new condition so d.c. is where in the future hydrogen be used to drive all the ships operation systems including ocean nothing yet this is just a big city within 2 years. we'll be starting all you see on the small school ship in the states are already established. fans and fairies posed by green hydrogen are just part of the picture in orkney pioneering research into how the few 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 40000000 flights world why it result in heavy c o 2 emissions search for an alternative fuel scourge and. one company collaborating with scientists in orkney is cyril aviad. eye contact director sergei kizza live from 6 am but their 1st 15 minute long hydrogen test flight it was the culmination of almost 3 years of research and that frankly it was that it was as if i deliver it maybe the full year was so relieved and so excited that i am and know that you guys are planning to fly here with one of your hydrogen per plane and. the final flight of our high flyer one project

we'll. the taken place on board the orkney is our famous for its 3 hydrogen. can you give us a timescale of when you think that we will see passenger planes in the sky running on hydrogen of course that the technology is in their infancy but i personally believe that. just into 20 years there will be a lot of jets flying using hydrogen and this is truly exciting. so if 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 that green hydrogen can be part of the answer. green hydrogen is beginning to take off it's a key part of the become the world's 1st carbon neutral continent by 2050 new projects are 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 as one of a number of current trends that herald a world free of fossil fuels there is definitely a new power system and a new energy system emerge out of our eyes whether we look at power generation and distribution or whether we look at transport 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 racking moment because we know that if we don't get the hot 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 differ. and track and wean society would be a society that has 100 percent clean energy that energy would be decentralized cheap ubiquitous we would be able to provide power to every single form on this planet we currently have 800000000 people who do not have access to power meaning there in abject poverty by moving over to 100 percent clean energy decentralized we can make energy too big that 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 grids that has storage of vailable to all the renewable energy generation sources would also be a 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 transport would be using clean fuels and finally cities would be clean why it because we would have put the internal combustion engine into the museum and cities would be organized into smaller communities around food and energy at the beginning of the most decisive decade in the history of humankind it behooves all of us to understand that this has been challenging and will continue to be challenging but we can do that's why we can address climate change in a timely fashion we can alert the worst disasters of i'm changed and in so doing we can bring

a much better quality of life for all citizens. this planet and certainly the ecosystems upon which we depend. people are cross the planet are spending an increasing amount of time online from work meetings and catching up with friends to movies streaming and shopping we're 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 cost everything we do online passes through data centers which consumes huge amounts of energy and emit nearly as much c o 2 a c airline industry i'm in no way to see how once into is harnessing the energy of these fields to stow our digital information without a heavy koppen footprint. this is

a famous tourist attraction and photo hotspot pub is stolen in 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 where that could be. in the 1st time i ever imagined this now and you're asking i haven't been thinking about it now i have no idea a standard google i guess in the cloud in the cloud and you know what the cloud is . a. storage place. like myself most people only have vague ideas of where all our data is cat i've come to university of stavanger to meet an expert on data storage and find out where our selfies end up. the photo is so will be a story in their memory of their foam and then if you will share the photo all you

want to back up the photo into the crawl it will end up use some data santa remotely could be an europe it could also in the remote across the atlantic coast they've accumulated in those data. those war will force us to have a big a big debate a santa so there are problem for us there in the. wrong on 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 covert 19 pandemic. our unlined 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 watt light bulb for 17 seconds that doesn't sound like much until you realize

google and loan process is 3500000000 searches a day around one percent of phallic tricity clovelly is consumed by data centers many of which provide remote storage facilities what is also known as the cloud is estimated that in 10 years is our data network grows almost 7 percent of all electricity will be used just to power and cool huge servers preserving everything from billions of family photos to big data on space travel so where and how you store your data can make all the difference and know ways ahead of the game on this since it's power at nearly a 100 percent by renewable energy most of which comes from hydro power. i'm on my way to enter an island near about. to have an old military storage but instead of storing to keep. it's they now stole billions of bytes of information from all over the world the underground green mountain data center which opened in

2013 its cup a neutral is run and hide to power from. the mountains for question nice to meet you nice to meet you as well. oh oh. wow. this is like being in a james bond film. i can see that this is very secure. very secure. well thank you. this is how it looked. when we took over there besides here is empty space but it will not be empty forever and as soon as we grow we'll be a data center as well. so no we're entering. what people refer to as the cloud this is where our customers are running their server storage equipment

so what kind of information is going 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 now they think white and fluffy but actually the cloud is miscavige and it's. and it's noisy it's black and it's noisy and it comes to a lot of power and generates a lot of heat to see how the center manager says it's a quick ride down the corridor. where in the future this is where all the green. and you flows through into the data so this is basically the giant engine of this data center the consumption in this

data center of 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 to vittie inside the data center. if it's in norway is free or new. as well so in a using green energy this data center is reducing its impact on the environment by cooling its servers choosing cold water from the nearby deep salt water inlet a fuel load so whilst most data centers use around 40 percent of the energy to cool servers which would otherwise reach 100 degrees celsius in minutes this data center gets its cooling free from nature so this is rare produce in cold water use cool cloudy and most.

cold sea water from the fjord into sebastian next to the data center this water which is constant 8 degrees celsius is then pumped up through the heat exchanger cooling down separate water pipes that circulates through the data center the warmed up siebel to then exits back into the field at around 20 degrees celsius where it quickly cools down again the green mountain data center in no way is unique because of the fuel load cooling the servers and the way in which they've repurposed an old site but all over scandinavia tech giants like facebook google and microsoft are building huge data centers running on hydro and wind power in fact investment in nordic data centers is set to double by 2025. thank you all work the kids won't drink i'm eating cereal a local green investor who's confident this trend will continue and this is where

the hydro power is yes. it's actually the world's longest 4th toast in 444 steps over 100 years old so be careful so i can see that it's all wood from this old train here. here you see the old pif coming down from the mountain so all the water is just following high speed in the pie creating electricity when it hits the turbine so you have to use what nature gave sears saw in norway we have in the credible rain or the contrasts sun yeah we also have wind but here it's rain that gives us electricity scandinavia will be important to the world's data storage i think skin in the area will be very important for future data storage it's

a cold climate you can use the cold fjord to cool down the data center we have a poll worker to run data centers however i think we also need to be even more responsible and take action that each one of us and for instance if we are talking about data storage we need to be concerned about holeman itself is we need to take whole many emails and slaps and text message we need to say. no we can't 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 on line and around 1000000 new uses sign up each day as our reliance and 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 balance our modern lives with what this planet can sustain.

with so many of us talk of time during the pandemic it's been 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 pledged. 0 carbon targets by 2050 but right now 20 past he's the king yeah that's just under a decade to determine the future of the planets. around the world we're already seeing glimpses of the clean society that could be ours last year renewables over to fossil fuels as the main source of electricity in europe and the u.k. in a straight at the side of britain panels on rooftops of one in 4 high runes the knoll was about solar complex and morocco serving its 1st space and it's already producing enough energy to power the city of america cash twice over. a 60 percent of monthly cost cells and no way our electric diesel cars will be back on there in

2025. the summations of already that they just need to go global to make a real difference to have that chance at a clean green and prosperous future. from the north of africa they crossed the mediterranean and made huge don't hold. build a new future in this circular. in the long 2 friends is 2021 contentious so-called separatism as we look back at the history of muslim immigration to the country into 3 parts. muslims are from it's episode 2 onal jersey. we understand the differences and similarities of cultures across the world. so no
