with these issues, i sure i did. ah, you know, we're live channels. we are not afraid to happen. delicate topic. africa population is growing fast. and young people clearly have the solution, the future as long as 77 percent of every weekend on the w. ah. ah, welcome to global 3000 empty seats. power, brazil and schools are trying to attract students back to class. pot i in the steel

industry, needs to clean up its act. is that even possible and low current? how south africans cope with an erotic energy supply. without electricity, our modern world would grind to a halt. no power means no mobile phones, no internet access bridges, no heating, no cash machines, trains at a standstill and no petrol either. and crucially to it means darkness. according to one study, last year alone, 350000000 people worldwide experienced major power outages. why do they happen? poor maintenance of power plants lack of modernization or simply to few power plants for the growing demand. on top of this climate change driven extreme weather regularly brings down power lines and pilots. in south africa, power carts are a frequency parents for years. the state attic tricity supply has struggled to meet

demands. things with the means to find a way around when it's dark and the power goes out. it's especially hard 2 and a half hours of total darkness and large parts of pseudo. because the national energy provider can't generate enough power and it happens up to twice a day for no one to love debate, it means that her scans won't be ready in time. they need to be banked fresh each day if they're to sell like hot cakes. normally business is good enough for nope, which will do bad. and her daughter to get by. but recent weeks have been tough. the power was switched off daily in their district. a state mandated energy saving measure, known in south africa as load shedding. we don't shaken good. see

here shedding is driving us crazy, loving them. i have a small business and we're trying to grow, but this is holding us back a long time we gazed in. sometimes i have things in the oven when they shut off the electricity and i can't finish baking them in. then they all have to be thrown out . agatha, she's angry at the government. 2 and a half hours without electricity means getting her, scorns to market that much later. and then cuts into her earnings the whole country is suffering as a result. for the past 15 years, south africa state owned electricity provider has had to interrupt supply to certain areas to prevent the power grid from collapsing. however, this winter has been especially hard and it's affecting all sections of the population. janice schecter is an entrepreneur who also runs a guest house and one of johannesburg wealthy suburbs. her life is organized around

the power outages. so we have as low as that shows, pu supper, where we're going to have maintaining that we're going to have stage went from 7 am to 4 pm and i, if we weren't on the group is going to zoom in the suburb, the power will be switched off every night this week, at least they're stover ones on gas. so luckily we can finish making dinner. we can, we can, we can be on line for fun on the hall. usually we actually sit and chat. i. yeah, there we go. okay, sir. okay, so would i need to do a need to get some lights on? well, yes sir, janet schechter turns on the battery powered lights that were charged during the day and are distributed throughout the house powered by a battery. and this recharge as, while the power is her husband brings

a battery powered light for the stairs. so no one falls down when coming down to see that this is the darker side of south africa is so that august of 5, the country has all the raw materials. it needs to produce energy, mainly domestic coal. it's bad for the environment, but there is enough of it. there are enough power plants to, but after years of mismanagement and corruption, there so poorly maintained that they're feeling more and more often. the power has never gone out as often as it has this winter. those who can afford it are making themselves independent from the state power grid in johannesburg. many are installing solar panels. the ideal solution in a land where the sun shines for 9 hours a day, even in winter. that's crazy busy. it's. we typically rain the demand to people wouldn't understand. we getting up to 500 phone calls a day. a lot of the people that tell us just less money. it's so long.

take lunch in the power cuts are promoting the use of green energy, but only for those who have enough money. most people here can't afford the roughly 15000 euro investment. for many years ago i'd the we, we headed the electric stove and we made it a conscious decision to move away from electricity. we had a nice serene top glass top and we moved away from the the glass top and we went to guess. i would suggest to 2 people out there to look for you. alternate of sources . look at green energy. look at your sailors and see what's available on the market . he advises people to have as many different energy sources as possible. that way there's a back up if one power source fails. but that's too costly for people in the townships . not only do they have to live with the power outages,

the constant shut offs have damage. no, go to la. do bed stove. it still hates but only on the highest setting teacher or an offer. yeah. get back to me that i have to go to a meeting and i wish the government would listen to us because it's not just my stove that's broken. it's my fridge has stopped washing my tail with keith. when the power came back on, there was a power surge. and now i don't have a fridge. let a government good tell us when a let this thing and and she just doesn't make enough money with her scans to buy new ones. in europe to the war in ukraine has led to rising energy costs and fee as of fuel shortages. more than 50 percent of the energy used in germany's manufacturing sector comes from electricity and gas. the chemical and metal industries are the biggest consumers, but they also offer the greatest potential when it comes to reducing our overall energy consumption and cutting greenhouse gas emissions. this is the

metal that made from modern world tick. imagine life without it. now cause poems, duchess, electricity. but this one, the material that alive the built around tarry, the dirty secret that nobody's talking about. the steel industry is responsible for jaw dropping, 8 percent of the wealth, greenhouse gas pollution. and bizarrely, we're actually going to need a lot more of it to clean up our economies. so how can we make steel green and what's wrong with the industries favorite solutions? there are 2 reasons, the steel making process of so dirty. the 1st is purifying the ion or needed the steel, but heating i annoy the charco, fires o mixing it with coca cola and big blast furnaces. you can extract pure iron from rock. not because oxygen atoms in the iron ore fly off and bind with carbon atoms

in the cold. what left behind is essentially pure iron known as reduced. i'm. and a whole load of c o 2. the 2nd reason steel sat said that it takes colossal amounts of energy to power this process. and most of that comes from you. guessed it, burning cold today. 72 percent on a global level are produced by this production developed. this is vito ever touched a steel analyst at german climate. think tank a got in a given the he says we're running out of time. the investment decision, steel make of make to day a crucial because the coal fired blast furnace of have a lifetime of 15 to 20 years. and after that need to be repaired or retired. the 2020s are very critical became in disregard because more than 70 percent of the global blast furnace will reach the end of the campaign lives and

require reinvestment and re investment decision. so what should still make be doing right now? either j hydrogen, hydrogen gym wonders of hydrogen, hydrogen to the gas and fuel that can be made cleanly with renewable energy. oh, much less clearly with fossil gas. if you reduce ion or with hydrogen, oxygen atoms no longer react with carbon atoms to make c o 2. instead, they react with hydrogen atoms to make h to the beauty about this concept is yes, you need a new production process. but as a byproduct, you have water instead of c o 2. and this is how we can make the feel making process time. the 2nd step and then feeding the purified ion into an electrical venice. these devices meltdown scrapped steel or reduced iron with high currents of electricity that turn them into liquid state. and ideally,

they would be running on electricity made from renewable energy. that's pretty much what swedish steel make a s as a beaded last year when it deliver the wealth 1st batch of fossil free steel to comic of over europe. steel. make a betting that hydrogen will be the future of steel right now. it costs more to make the switch, but if gas prices stay high and carbon taxes rise, switching away from fossil fuels will become increasingly attracted from a business perspective too. but of course, using hydrogen to learned doesn't make steel, greek. it's a process with several layers. kind of feels like an onion. this is kaitlin's wallack, a steel analyst at the u. s. based non profit global energy monitor. the 1st layer is to make sure your electric arc furnace unit is running completely on, like green energy. but then you need to make sure that the reducing agent and the direct reduce iron plants is hydrogen. but that's not enough. you have to make sure that that hydrogen is actually being produced through an electrolyzer that's

operating on 100 percent green. ah, renewable energy. sir, time for hydrogen. right? well, unfortunately, we're the catch. you need a lot of hydrogen like ready loads making will to steal into you out of hydrogen would require about 6000000 tons of the gas just to satisfy the steel industry. hydrogen, if you need almost as many wind turbines of the you have to date as not impossible, but it is a logistical nightmare. one of the big challenges is where we build these hydrogen ah, production facilities. it needs to happen in places that have that renewable energy capacity for the problem so far is lots of still making regions, dirt habit capacity for at least don't have plans to build a top anytime soon. and piping or shipping green hydrogen from elsewhere requires

infrastructure to do so. and that all mean hydrogen can't be the whole solution. but the powerful waste simply by the problem that sounds almost too good to be true . recycling, you might not expect it, but still is already one of the most recycled materials in the world. more than a quarter of the steel may to day comes from recycled scrap steel that nobody needs that basically because the 1st step of purifying iron or is expensive melting out wholesale. well, that's much cheaper. we have a rising stock of global steel scrap because whenever a car, whenever a breach, whenever a building beach at the end of the lifetime, this deal scrap is collected sorted and then can be melted in electric oxygen to produce new still recycling most steel could massively help in cutting the industry of energy demand. but there are limits. each time you price

a steel little impurities, like cauffron nickel can sneak in and we can the metal. that means you can't recycle forever. a 3rd solution is to keep the blast furnace as we're already using, but catch the emissions before they escape into the atmosphere. that's what advocates of carbon capture cooling for. fossil fuel companies say the principal, as simple. stick a box on top of the polluting pipe and sack up the c or 2 that comes out so you can use it in industry or start safely underground. the reality is trickier. today, capture rates are often low and casa hot. what's more, the fossil fuel industry has used the promise of carbon capture and storage will cease yes, as an excuse to keep on polluting. but when it comes to decomposing heavy industries, i must do broadly agree that ccf the vital role to play alongside hydrogen. we're way behind and where will departmental shelton's going? and it is largely down to complete an auction on the of the policy level. this is eva panel from the cleaner task force. it's one of the few environmental

organizations calling to put money into capturing carbon. one of the reasons why we know we don't know answers to questions like capture rates or how would it work in a commercial scale is because your company's hunter actually reduce their mission. the international energy agency expects carbon capture to cover half of will steal production by 2050, the climate friendly scenario. if it works, it would free up hydrogen to be used in other processes that are also hot clean. but to date, we don't really know what chair of emissions ccrs can actually capture from steel. if steel make a stick to blast furnaces, but c c s doesn't quickly become cheap or efficient. the cold a burn, we'll just keep on polluting. we console steel by giving up on it, but there's a huge amount policy makes and companies can do to get the tech solutions working access to education, a shared learning environment and

a group of peers barely anything is more important for children. but the corona virus pandemic turned life upside down for around one point. 5000000000 children worldwide. with schools closed homeschooling and remote learning became the reality for many education was already a global issue. even before the pandemic, the 258000000 children worldwide had no access to schooling, the pandemic made the situation much worse. for months, 463000000 children found themselves out of school. and even in early 2022, millions of children were missing from classrooms. most schools have reopened, including in brazil, but many children are still staying away to i. hey, victoria, lima loves to slew the route. she wagner and gabrielle have tough cases to solve.

together there for school detectives on a special mission lies them again and if you go back and i l u vomiting. got that was c, as in nancy, where detectives, because we look for missing students and bring them back because he wants to kill somebody. when there's school in rio de janeiro reopened a year ago, almost half the students didn't return. during the pandemic homeschooling was an illusion, says principal carolina taylor. a lot of students have no smartphone or internet access. they stay away, but schoolmates track them down. but when each with asian life, it's good for the children themselves to play a major role, you think they can motivate their classmates in the say, i'm here, learn any, come and join us like he them say the wish that the school sleuths are inspired by budding detectives from tv shows and the principal found their outfits in carnival collections. dressing up makes the paperwork more bearable. together they pour over

lists. students who are often absent or fell to hand in assignments will get a phone call later or personal visit. 1000 students, one goal with visitors don't cancel in the wrong things on the street and they should come to school and learn something valuable. every one should go to school in bush. oh, oh, carolina taylor looks artful. her students here their days are structured and they receive a meal and moral support for to annie. her principal is a role model and confidant. i wish this isn't much for martha. the children need to change their reality themselves at age. now the school is open and waiting for them as follow up. i may have to buy wild only. yeah, they are planning to pay a surprise visit today. katie, though not far away from the school. cutlass edwardo is also looking for missing students. known as car do,

he's one of the few who venture into the fabulous insert of them are my places that are socially invisible. visibility. 6 with young people, don't you talk about already forbid, if you will grab there's nothing here after hit me for president of forgotten place . dorothy, now i got gauge garcia, students are older. so instead of studying many of them work to help support their families, will he find missing students here? any one who wants to enter this for vale or needs to know someone like silver people year work without contracts or future security. and as brazil social inequality grows, so do the frivolous. without it occasion car do says it's impossible to get a good job. suddenly high school dropout, gabrielle shows up nice all up, but on which one would apply? no, savage, air conditioners of the scrap yard was this. i watched up when the meal was his new

dropped out before the pandemic. right. right. and phonology. and i've done that in a couple of the launch gabriella, before the pandemic. but like so many, we weren't able to reach emily about, he's one of those who dropped down. i mean for you can do have gabrielle, will return and that schools won't have to close again due to curve at 19. each quality shows and cools be no safe space, no food, no education. meanwhile, carleen taylor and his students who are on a visit marlena to faces pacheco when school reopened, the children didn't show 3 missing kids with the same last name. the detectives alert at the principal the one when the student may area to me, they all shouted principal catalina. then everyone knew i was tell you that. but if everybody who do back then she puffed by in person, because marlena didn't realize school has started again despite all the news in the

papers and on social media. that's because marlena is illiterate. you don't wish you can get a basket. i don't want my children to be like me. i can't read and write and i want them to go to school and have a future scala. wonderful, thank you, ma'am. a lot of students will need years to catch her. back at the school, the 3 detectives are handing out documents for the new academic year. after the holidays, they'll be moving on to high school. they all plan to keep on studying. i feel like you know, things going to prefer. my dream is to be a teacher and a principal though, so i need to work hard. i don't my some a proof that i'm the bow of the tree. i will have to be replaced by 3 new detectives as they've accomplished their mission. by the end of the school year, almost all of the missing students were back in class.

i don't, it is a person's best friends. well, they're suddenly one of the world's most popular domesticated animals. estimate suggest around 470000000 dogs, a kept as pets worldwide. but the picture is not always is rosy as this one. millions of dogs a cast out by their owners. every year. they end up in rescue centers or roam the streets as strays. exact statistics are hard to come by, but animal rights activists suggest as many as 202500 1000000. and the pandemic st made things worse. bako has a new sweater. something he could have only wished for when he was still living on the street. but now when he has a new owner de la plus, i give me a buck for more amid ice. it was love at 1st, scientifically. when i saw him, i thought he so beautiful as will believe what he also seem incredibly old. holy cow. cool. but i'm pretty sure he was abandoned renella quite

a bit. backer likely doesn't remember much about his former life. he was probably left on the street by his previous owner at the beginning of the pandemic . in los angeles, gomez, the only allowed thought ask was there and he couldn't see out of one eye and the vents, suggested surgery to remove it if case they thought he'd been beaten very badly for the war. so he underwent and operationally seattle here use that animal rights activist. andrea galindo was the one who found him. that when i said the death during lockdown, rumors circulated that posed a threat to every dog in bogota via the user if what that really. but okay, it was a horrible that people thought that dogs were spreading cove it. oh, don't know. people just abandoned them. no matter how long they had the dogs to what i have even 7 years in coffee at those times. it was just merciless and

terribly hard on the animal when we thought, oh my daughter, what they were used to surviving on the streets outside. like i did suddenly they were alone. i did rebels. yeah. those hill lip about for over 2 years, volunteers have been working to care for the strays they collect food and trying to provide veterinary care. but there are just too many dogs impulses at the, almost at lithium. yes, we receive donations and people help us out. i don't, there is a lot of solidarity young echo more by ease i asked, but people have to be able to afford it is yes, yes, fun, good on this. and there's a lot of social inequality in our country. fact cons, ha. and that means that we can't take care of all the animals on the mileage. some of the dogs are lucky and find a new home like pocket did. the son of paco's owner is really happy about having

a new family member and polco. clearly he's pretty happy to look it up that there are 2 stray dogs roaming around, but we can improve their lives. yes, m u for animal welfare activist, andrea galindo, paco's new life is validation enough for her work. she is lost, count of how many dogs she's helped, and every animal she finds has a place in her heart known as i think. i feel, you know, it's hugely gratifying. i always tell myself that's one animal of humor that suffering. but too few strays are as lucky as poco, whose new owner says fate led him to her. is legal. these i, because the pandemic gave us pocketbook giggles. i'm was gays to give to you. we have no idea how much you change your life. the daycare left feel. i think he was

predestined to find us. so look at 4 more. it just take him 3 years to find ourselves. the goal is to be fun. this is his home, but it does look awesome. there are still over 60000 stray dogs in bogota, each one also hoping to find a forever home and that, so from us at global 3000 this weekend, do drop us a line to global 3000 at d, w dot com and check out our facebook page d, w global ideas. see you next week. ah, [000:00:00;00]
