to be. discovered. subscribe to the documentary on you tube. you thought the coronavirus was big or climate change is an even bigger challenge facing the planet but the current health crisis has been a boon for green energy dramatically lower global demand for electricity during lockdown has allowed bridge new balls to flourish they also make more business

sense they're increasingly cheaper than fossil fuels like coal which is turning out to be one of the most expensive sources of power green energy for the future a topic all made the business short. coles biggest threat now is economics but there's still a heap of it used in the making of steel the sector is one of the most energy intensive around the production methods about the change since the 1st industrial revolution of the 18th or 19th centuries usually ion or is smelted in blast furnaces where the impurities are removed and carbon is added by burning coal that lets off huge amounts of carbon dioxide into the atmosphere but changes in the air and you're a of steel making is here without the high emissions. heavy industry doesn't get much heavier than this steel production to. can the metal be

money factor using green alex received at this factory they say they can. seal production is responsible for around 5 percent of global c o 2 emissions but here are. the aca they've slashed their output of the greenhouse gas and this is how. with conventional steel production where coal is burnt in a blast furnace c o 2 emissions are 3 or 4 times higher than with steel recycling using an electric arc furnace. conventional steel production involves the combination of iron ore and coking coal which takes place in the blast furnace when melted the or produces war pig iron. the iron is then melted in the conversion are together with scrap metal to produce crude steel the finished product is used to make items such as steel

girders burning hard cold limits of 2000 the kilos of c o 2 per ton of steel produced. that figure is far lower with green steel because it involves recycling here scrap steel is fed into an electric arc furnace the electricity comes 100 percent from renewable sources such as wind farm. 2 emissions amount to just $110.00 kilos per tonne of steel. the scrap steel comes in all shapes and sizes from waste incineration plants and dealer is primarily from the surrounding or valley region. and this is where it's recycled this specific mix of different kinds of used steel is collected in huge scrapbook adds. they are then conveyed to the melting hole which measures some 40 meters tall. everything here is super sized because one of the biggest electric arc furnace is in the world is about to get to work. howard by alec tricity with

a node of 61110000 volts generating a loss of. these graphite electrodes measuring several meters long built up a temperature of 1800 degrees celsius in the furnace will soon see and hear the resulting spectacle. over in the control room kevin visits house has. just added a special mixture of scrap steel this is if we should be seeing a change in the furnace from the sound. normal it should be getting a bit quieter. that's why it took 10 years of experience to master the job. in the biggest danger is always a failure in the cooling of the electric arc works with a huge amount of energy at temperatures of up to 3000 degrees of molten metal as he said to 17 or 1800 degrees so if the cooling fails the furnace will melt itself

a mortar and steel are not compatible. with. the melting process is over he retracts the electrodes. his immediate boss is in charge of both the melting and the steel production process. the steel that's released or top from the furnace before being processed. what we have here is a special design a furnace that's pretty rad so it's exciting coming here every day and seeing the crew through material they tended to precede. the factory has a high voltage power lines due to the scale involved they supply the entire complex with 350000000 kilowatt hours of energy a year making energy efficiency a priority. using scrap we already have low energy

consumption and c o 2 emissions. now producing green steel is a further improvement. in the future we'll be making it with green electricity. and the plants power consumption is enormous. vaca needs as much alec christie as the entire time to victor seen in the background its population 100000 people. the continuous comforting plans produces green steel in someone's eyes and different grades from bullet proof steel for limousines to a special bryson for medical implants. the sort of electric company we have 90 to 100 minutes between tappings which

means 13 or 14 batches per day than you can smoke on top. which in turn translates into around 1500 tons of steel produced every day upon except marketed under the green still able to do the lower and push a studio to. a new smelting procedure every time kevin but it's house prepares for a new batch it's something of an event he said most was a big motivation when i took on the job it's pretty special. then it's time for the fireworks. despite being produced with eco friendly energy in the company says it's green still does not cost much more than steel made with coal. to grown a virus pandemic has put a damper on the mood in the industry and the pressure to lower c

o 2 emissions is high and this deal could soon be used to fashion a truly green automobile. well in 30 years europe wants to become the 1st climate neutral consulate but that won't save the environment if other big polluters don't join the initiative south africa's hunger for electricity is only growing at the same time that the nation struggles through an economically damaging energy crisis it's been dragging on since 2007 widespread rolling blackouts a power utility riddled with mismanagement and corruption but turning out the lights on the country has spock's lots of ideas. one year ago the protea heights academy school in cape town when solar without paying for the installation the system was financed by a crowd funding platform the idea small investors buy panels and earn an income from selling the electricity to the school that is using them. so far abraham

cambridge's crowd funding platform has equipped over 30 schools and companies within 5 years they plan to have more than $200.00 additional systems installed. so if you want to put money in solar panels from environmental reason put them in south africa you're offsetting 8 times the carbon emissions with a side of our own here's africa than it would do in germany for example and we're getting twice as much electricity out of it so it just makes more sense to put a solar power away you create more social environmental and economic impact. and for the school the solar energy is cheaper than power from the grid with investments as little as 4 year olds sun exchange is also open to people with less income in fact many of the pupils at protea heights invested in the solar cells themselves when the horn is the school's former principal she says that aside from clean cheap energy the project also brings another benefit so we always that yeah kids are so excited aliveness to actually get involved and interested in your old

thing and actually buy still sells it sells and see how the money would increase or decrease or whatever i mean it was it created a huge interest in near real excitement and then it's also what you want to teach children for the features and tipper nearer skills and innovative models to fund and produce green energy are urgently needed in south africa the government aims to produce a quarter of all electricity from renewables by 2030. the ocean could play a role. simon weinberg's company developed an underwater pump powered by the ocean. swain's it turned some water into drinking water all at the same time producing a constant source of energy that could power up to 10 european households all year round. thanks. for. there is always energy. if we said we're looking at whole range of waves that come from different areas

there's a lot of stuff that's produced locally by the local winds but there's an enormous amount of energy that's come from storms that could be thousands of miles away. from the wave pump is time to a boy that lets the arm with each wave the lever movement pressure rises water to purify it and generate electricity at the same time for years the prototype unit was tested under water and is now back in the workshop for some maintenance. so far the unit has proven that the concept works the team says despite the challenges. the challenges with the ocean is that it's an expensive system to develop when there is very little funding available so this is why it's taken so long to get where it has today with sufficient funding the company could start to build larger pumps next year that would feed into the power grid the sun

exchange crowd funding platform meanwhile has just received an additional $3000000.00 euros from one major investor powering on south africa's green energy transition. here's a more clever guys who were acting early enough to be head of the game a decade ago the founders of big box met at university and decided to bring solar systems to remote parts of africa today the london startup provides hardware software sales and customer services for green electricity on the continent concepts was ditching national grades for locally sourced solar energy networked via the internet. supplying africa with solar energy via their headquarters in london might seem like an ambitious goal but it's one that b. banks is determined to make a reality for startups founders months or how many union christopher baker bryan want to end global energy poverty. and describe ourselves as a next generation utility company that means we're providing

a lot more than just electricity to our souls but things like internet access and access to water services and cooking gas for example it's all of those basic modern services that we take for granted here in the western world that our households and our customers on the ground are really striving to achieve locally. the 2 men met at college over 10 years ago together with their other partner the beginnings of the venture were modest as a students generally organisation the budding engineers vision to bring solar systems to remote areas and to link them up digitally humanity get some funding from our own university from other sponsors as well and we were able to that some provided a facility some 60 households in a rural part of the rwanda and i think but at a time when the thought system got installed our 1st customer that was really

applying that was very transformative in my own personal life because everything is theory until that point we saw this real major global challenge of billions of people who lacked access to reliable electric power and we may be naïve back then felt that we could do something to make an impact. and the engineering students efforts fruit they developed the b. box a digital platform that connects off grid solar systems to a central server the system can for example detect technical problems ahead of time and correct them the boxes are currently provided to 10 countries mostly in africa the company also supplies the corresponding solar panels and has so far served over a 1000000 customers. people already spend a lot of money and spending money on kerosene candles batteries for radios very bad diesel generator to spending tens of dollars a month on this sort of stuff so could we take that money that they're already

spending on energy and giving them something better you know if you included in here the c.e.o.'s are in close contact with their branch offices in africa but they want to keep their h.q. in london. and that's where they find the programmers and engineers they need. it's also where the money comes from. the boxes yet to make any profit but they've just raised $50000000.00 u.s. dollars from international investors. one of the key things to be able to achieve millions hundreds of millions of people with access to electricity is to bring in partnerships the likes of us who we joined with in the last few years in office in togo and mitsubishi who invested in the books in the middle of 2019. those sort of partnerships help us achieve the scale that we need to to achieve over the next few years in order to make a real significant impacts the concept could be put to work in europe as well according to the be box founders but battery prices would need to go down for that

to happen still their main goal remains to serve developing countries. my dream would be at least to spark one of many sparks that traits that transformation that. nations need to lift themselves out of poverty if even if you create. universal electrification in one country i will be extremely happy and there's so much more to do there are still around 900000000 people worldwide who have no access to electricity. forests the lungs of our planet are an effective way of hoovering up pollution and according to scientists also help slow the global average temperature rise treece carbon dioxide out of the atmosphere and look at a way in their trunks and soil collectively they also protect biodiversity and provide natural resources we continue to chop them down at an alarming rate.

for centuries our species has have a close relationship with the forest forests are more than a backdrop for fairy tales they provide us with food fresh air and clean water and played key roles and biodiversity and climate their essential habitats that are now under threat. every single 2nd a wooded area the size of a football field is destroyed. and almost always we are the destroyers there are no monetary reasons why humans would want to protect wooded areas on the contrary when turned into raw materials forests can bring in big profits. wood products are growing in popularity whether it's for paper furniture or chopsticks in some regions of the world it takes up to 7 trees a year per person to meet demand. many of these wood products come from

illegal sources up to 17 percent of the global trade and timber is illegal in brazil that number jumps to 80 percent an estimated 19 percent of you timber imports come from illegal logging and that's not all humanity also destroys forests to create farmland for the production of other raw materials like palm oil soybeans sugar cane or beef billions of dollars' worth of those products are bought and sold every day and how many of the companies that depend on these raw materials are trying to participate in what's called the green economy which seeks to ease humanity's impact on nature only around 13 percent. if humanity needs more farmland or space for new cities the forest always has to give way. as our numbers grow the forests shrink. worldwide 40 percent of

them have already been cut. with no thought for how much we owe them they've given us life saving medicines paper corks chewing gum and one of humanity's favorites. have educated know this if you flew into germany you've noticed the highly industrialized and biggest economy in europe is actually quite green a 3rd of the nation is covered in forests that's a lot of work for a forest ranger my colleague all of craig decided to put himself in the shoes or boots of a forest for the day. oh hi i'm the new guy here masquerading as a forest. talk to go high key get ready to go into the woods not like that get your boots on . ok boss. forced us to discuss that.

momentum. the lines i'm slowly but surely creak as turning into a force that some 1st like. regular lucky the risks here are tripping over a root being attacked by boards and being hit by a tree they're a threat to everyone in a forest i don't think most people crawling you know that is true could be.

a model but you shouldn't be able to see through a healthy each tree. good even though you might think i'm not everything so green oh nice. this was not you we've got it all figured god not at all you don't recover either it's completely dead now to single leaf left the bark has burst open. this is it you know this is dust from the beatles who drew their way inside they already inside their work made of insects that are already inside the tree if you look a little higher you can see the drill holes where they thought they were all and the index from a woodpecker looking for larvae. what do we do with this guy it has to be felled this one too. this one definitely needs family most. how long do these trees usually live a little blue book on the beech tree can live up to 400 years well you know when i

got 400 years and these trees are over 150 years old. i thought it's getting dangerous i'll go in alone it's good idea. i'd rather not go and. go. come come come. across as on this being a force there's nothing i'm sure but i'm a bit scared of these bourse they huge and the maid looks aggressive and they are all on high alert because the baby's mom is really looking up here they are now.

look at the cost to us super shop yesterday off again it's called types you think he's driving them on. the boss was. very good. oh. i would be opting out of this one but it's all about the swing you need proper momentum this isn't a name fight it's an x. so i'll swing swaying swing it's very important varying on target.

i have a blister no one cares. so we're cutting what it's easy. and i think i don't pretty good doing it. jokes aside it is tiring imagine having to cut enough woods to heat your home for the winter. and i get blisters so easily yes and i know here's one. that's proper work. i've wanted to be a forester since i was in 1st grade and it's always been my dream and i found my dream job i'm living it. what about the next generation of forest. luckily the career prospects are really good it's always nice to have a grown up with it wouldn't be much food and i'm really proud that my daughter is

studying forestry and maybe someday she'll become a forester herself would feel like a fossil to. me. i think i cut quite a good figure i've proven my woodcutting credentials would you say i've got what it takes to be a force. of the. image down and running around here in that outfit in all these temperatures can be quite a strain as a forester you have to roam around a lot in the forest you seem to be up to that you were a pretty quick learner i describe you as an internal with the potential. great being a forest road so. much for ever. with this i don't. rooms

displaced starts on. tobar 16. this is the w. news live from berlin and athens court delivers a landmark verdict in a marathon trial protesters clashed with police outside the court while inside leaders of the far right golden dawn party a found guilty of running a criminal organization also coming up u.s. president trump stops talks on a stimulus package for the u.s. economy congress fails to agree on how to program is misses and consumers as the feed warns americans will face unnecessary hardship. and 2 women when the 2020 nobel prize in chemistry for they work in developing a method to think gene ups

a manual shutdown t.n.a. affronts and jennifer doudna of the u.s. was recognized for what the academy called rewriting the code of law. i'm anthony held welcome to the program a great course has found leaders of the country's 5 right golden dawn party guilty of operating a criminal organization the group was once greece's 3rd largest political party its latest now face between 5 and 15 years in prison a supporter of the group was also convicted of the murder of an anti-fascist rap in 2013 scuffles broke out outside the courthouse between police and anti fascist protesters whiting for the verdict. if a roar of applause outside the courthouse where the far right golden dawn party was

just declared a criminal group thousands of anti fascist protesters have gathered here to await the verdict in a trial that lasted over 5 years and so almost 70 defendants. for the greek people's conscience golden dawn is a criminal organization and will end up where it deserves in the garbage can of history as is appropriate after the battles waged by the people and this country. cheering erupted into clashes with the police who deployed tear gas and water cannons after some protesters threw stones and molotov cocktails. inside the court house the judges the clear 7 of the party's former lawmakers guilty of leading a criminal organization others were convicted of taking part in it. the court also found

a supporter of golden dawn guilty of killing leftwing rapper. the greek prime minister expressed dissatisfaction with the verdict or for schools as prime minister i consciously refrain from commenting on court decisions as a greek citizen however i share the universal satisfaction for the recognition of golden dawn's criminal character. golden dawn was founded in the 1980 s. as an obscure and you announce you're going to zation it rose to prominence during the greek financial crisis entering parliament in 2012 as the 3rd largest party. the group is strongly anti migrant an anti muslim and its members have been accused of carrying out acts of violence against minorities but the wind has changed last year will depend on fill to win a single seat in parliament now after being dubbed a criminal group its political aspirations may have come to an end.

journalist in athens says the greek capital remains tense in the hours after the verdict. well the scuffles has actually pretty much died down they were pretty tense at some point and quickly after this verdict was sounded across the the court house initially there were kind of. of celebration and clapping and applause but then quickly we saw these scuffles breaking out between far left activists and the police as a result the authorities struck back have fired tear gas to disperse them protesters also fled the scene and. tried to seek some kind of refuge in inside streets but at the same time however authorities are telling us that at least 2000 plus men who were deployed for fear of violence today will remain on the

ground in case there is yet another flare up of violence that we saw earlier today as journalist. in athens ok this time now to some of the other stories making news around the world. according kenya has found 2 men guilty of involvement in the 2013 attack on him and the market shopping mall in nairobi and the 67 people killed in the mass shooting and subsequent siege at the westgate shopping complex the 3rd defendant was acquitted. the european parliament has voted in favor of significantly reducing greenhouse gases by 2030 has agreed on a 60 percent cut across the bloc compared to 9090 levels that would require a sharp drop in the use of coal and have huge implications for all sicked it's it still needs the approval of a new member states. germany's foreign minister has called for european sanctions

economy this up to congress failed to reach agreement on a price tag democrats including biden blasted trump for abandoning the american public and the pandemics. the site of one of the bloodiest battles in the us civil will thank you all for being here used as the backdrop for joe biden's cool thing unity thank you. today once again we are a house divided that my friends can no longer be we are facing too many crises we have too much work to do we have to brighter future to have a it shipwrecked on the shoals of anger and hate and division. it is presidential opponent appears to delight in division donald trump may still be recovering from coach with 19 but he's refused to let that stop play in

a series of tweets about talks with democrats over coronavirus relief legislation the president declared i have instructed my representatives to stop negotiating until after the election. u.s. stocks fell sharply on that bombshell. hours later trump appeared to row back a bit demanding congress approve extra cash for the airline industry as well as calling for handouts to help struggling americans. it all adds to a sense of chaos in the white house trump's team trying to keep his reelection campaign on track while the corona virus continues to spread. here with the president's senior adviser in chief speechwriter stephen miller just the latest to test positive. trump continues to play down the fire as even after

his 3 days in hospital. joe biden says he won't debate the president if he's still infected well. i think if we do our program we should have a very. good trump insist there face to face next week will go ahead division even here and yet this show goes on. the winners of the prestigious nobel prize in chemistry have been announced in stockholm this year the prize goes jointly to jennifer dabbler from the u.s. and french scientist. for the development of methods the genome the technology is already contributing to new therapies against cancer and could help cure inherited diseases visited in her lab a couple of years back to find out about her work. it was a great breaking discovery 8 years ago emmanuel sharp and he together with jennifer

did not find a way to rewrite the code of life or d.n.e. neither the scientists have been recognized for their break 3 with the nobel chemistry prize. yeah i feel extremely new. to receive these ideas from cognition. from sweden it's a great discovery and not very happy to be one of those years. of cease discovering. the tears scientists figured out why bacteria defend themselves against invading viruses in the process they discovered that this natural mechanism can be used as a tool to modify d.n.e. . the result was the crisper cast in genomes that there's. a simple quick and precise tool to change the genome. here's how it works the sensors are

actually a protein which is given a kind of search term for example e.g. seen in this simplified model our d.n.a. is made up of lots of different combinations of codes like these the says are proteins scans a copy of the d.n.a. and when it's found the search words says are activated and they cut the section i . then a different section of d.n.a. can be inserted. what i think is is what is the most interesting and fascinating about this discovery is that you you dig into the nature and you try to understand that trying to make any isms of life anew and decipher and make an ism that you can really use and harness for the copper so for. the genome says are already being used by plant researchers to create a higher yielding strain of corn as well as mushrooms that stay fresh for longer.

unknown allergenic peanuts. the discovery has sparked heated ethical debates about the manipulation of nature. but there's no direct approach it's terrifying potential in the future it could also be harnessed to treat cancer or other genetic diseases. well for more on this i'm joined by les or back from the d. w. science also more about this is with us was this a surprise this time it was no surprise to be honest normally it always is but this time it wasn't but many have been waiting for this even though the findings were only published 8 years ago which is nothing i mean normally it takes decades for scientists to be awarded the nobel prize so it wasn't really it was really kind of a noble thing for the nobel prize committee here but up on cheers and did not find things out them so prone breaking and so widely used already that it's i guess kind

of fair that they deserve that they get the medal for this right now you know so i mean it's a great symbol because they're the 1st 2 women to get the prize together you know there are many cutting edge possibilities here as well but genome everything technology is controversy yes definitely it is especially as they're worked up on work is being used by other scientists as well there's been this case 2 years ago where a chinese researcher. edited the genome of 2 human embryos which yeah it was kind of an incredible thing to happen and also he was then and meantime he was sentenced to 3 years in prison for illegal medical practices. and of course this started a huge debate in the center fake world i mean scientists were wondering how far can we actually go when we added the human genome dury really want designer babies

where is the use where are the possibilities but where are the dangers as well. now there are groups that develop guidelines for their use for the ethical use of their chris burke has 9. gene editing scissors. so we have to see it but still as we heard the report there is no doubt that this is really useful and a really powerful tool so it deserves the price the finitely incredible from did to all the scientists thanks so much. a legendary guitarist and songwriter any van halen has died after a long battle with cancer. and 1972 together with his brother alex he formed the band by the band haven 10 years after their family had emigrated to the us from the netherlands haven't become one of the world's top selling bands with songs like jump i think that island is comfortably considered one of the greatest rock guitarists to vote on in a 65 years old. and

a reminder of our top story there's been scuffles outside of anathemas court. and found leaders of the country's far right golden dawn party guilty of running a criminal organization but it comes after a marathon 5 year trots the defendants face at least one music prison. they stop is business with stephen bits. of. this to some dope story a stubborn rice farmer from thailand. his problem pests. his credo no chemicals. and she's trying to. step.
