To be one of the most expensive sources of Power Green Energy for the future our topic of made use business. Coles biggest threat now is economics but theres 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 and 19th centuries usually iron ore 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 youre a of steel making is here without the high emissions. Heavy industry doesnt get much heavier than this Steel Production. But can the natural be money factor and using green algae tricity at this factory they say they can. Steel production is responsible for around 5 percent of global c o 2 emissions but here at deutsche it is tied back and theyve slashed their output of the Greenhouse Gas and this is higher oh. 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 pig iron. The yarn is then melted in the converter together with scrap metal to produce crude steel the finished product is used to make them 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 for ton of steel. The scrap steel comes in all shapes and sizes from waste incineration plants and dealers primarily from the surrounding who are finally region. And this is where its 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 for in this is in the world is about to get to work. Howard by Alec Christie with a load of 61110000 volts generating a loss of piece. 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 and this is it we should be seeing a change in the furnace from the sound. Normal it should be getting a bit quieter. It took 10 years of experience to muster 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 3 and a half 1000 degrees of the molten metal as he said to 17 or 1800 degrees so if the cooling fails the furnace would melt itself and steel are not compatible. Once 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 thats released or top from the furnace before being processed. What we have here is a special design a furnace thats pretty rare so its exciting coming here every day and seeing the crew through material they tend 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 i. R. C. Using sram we already have low Energy Consumption and c o 2 emissions. Were taking now producing green steel is a further improvement. In the future well be making it with Green Electricity. And the plants our consumption is enormous joy to egypt. Vaca needs as much elektra see as the entire time to victor seen in the background and its population 100000 people. The continuous constant plans produces great steel in someones eyes and different grades from bullet proof steel for limousines to a special variety for medical implants. The sort of electric car that we have 90 to 100 minutes between tappings which means 13 or 14 batches per day difference most of. Which in turn translates into around 1500. 00 tons of steel produced every day a product thats marketed under the green steel label due to the lower output of c o 2. A new smelting procedure every time kevin but its house prepares for a new batch its something of an event hes almost was a big motivation when i took on the job its pretty special if you dont. Then its time for the fireworks. Despite being produced with eco Friendly Energy the company says its green steel 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 but the pressure to lower c o 2 emissions is high and this deal could soon be used to fashion a truly green automobile. In 30 years europe wants to become the 1st climate neutral consulate but that wont save the environment if other big polluters dont join the initiative south africas hunger for electricity is only growing at the same time that the nation struggles through an economically damaging Energy Crisis its 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 spocks 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 cambridges 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 youre offsetting 8 times the Carbon Emissions with a side of our own heres africa than it would do in germany for example and youre getting twice as much electricity out of it so 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 as some exchange is also open to people with less income and fact many of the pupils at protea heights invested in the solar cells themselves when the horn is the schools former principal she says that aside from Clean Cheap Energy the project also brings another benefit so we legalize that yeah kids are so excited aliveness to actually have evolved an interest in your old thing and actually buy slowly cells themselves 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 that is also what you want to teach children for the future isnt to put nearly skills to 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 weinbergs company developed an underwater pump powered by the ocean. Swades it turned salt water into Drinking Water fall at the same time producing a constant source of energy that could power up to 10 european households all year round. For years. Theres always energy. If we said were looking at whole range of waves that come from different areas theres a lot of stuff thats produced locally by the local winds but theres an enormous amount of energy thats 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 are with with the ocean is that its an expensive system to develop when it is very little funding available so this is why its taken so long to get where it has to do 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 africas green energy transition. Heres a more clever guys who were acting early enough to be head of the game a decade ago the founders of b. 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 concept was ditching National Grades for locally sourced solar energy networked by the internet. Supplying. Africa with solar energy via their headquarters in london might seem like an ambitious goal but its one that b. Banks is determined to make a reality start ups founders months or hum a union Christopher Baker brian want to end Global Energy poverty. To describe ourselves as a next Generation Utility Company that means were 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 all of those basic modern services that we take for granted here in the western world that our households and all 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 Charity organization the budding engineers vision to bring Solar Systems to remote areas and to link them up digitally there managed to get some funding from our own university from other sponsors as well and we were able to that some provide electricity to some 60 households in a rural part of the rwanda and i think but at time that the 1st system got installed our 1st customer that was really apply and 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 naive back then felt that we could do something to make an impact. And the engineering students efforts soon bore 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 to correct 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. But already spent 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 take that money that theyre 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 thats where they find the programmers and engineers they need. Its also where the money comes from. The boxes yet to make any profit but theyve 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 without access to electricity is to bring in partnerships the likes of yes we joined within the last few years in office in togo and mitsubishi invested in b books in the middle of 2019. 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 b. 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 a spark one of many sparks that creates that transformation that entire nations need to lift themselves out of poverty if even if we create. A universe of electrification in one country i would be extremely happy and theres so much more to do there are still around 900000000 people worldwide who have no access to electricity. Forests the lungs of our planet they are an effective way of hoovering up pollution and according to scientists also help slow the global average temperature rise trees 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 had a close relationship with the forest forests are more than a backdrop for fairytales they provide us with food fresh air and clean water and play 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 its 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 in timber is illegal in brazil that number jumps to 80 percent an estimated 19 percent of you timber imports come from illegal logging and thats not all humanity also destroys forests to create farmland for the production of other Raw Materials like palm oil soybeans sugarcane 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 whats called the Green Economy which seeks to ease humanitys 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 all. Ready been cut. With no thought for how much we owe them theyve given us life saving medicines paper course. And one of humanitys favorites chocolate. Have if you didnt know this if you flew into germany youd noticed the highly industrialized and biggest economy in europe is actually quite green a 3rd of the nation is covered in forests thats a lot of work for a forest ranger my colleague all of creagh decided to put himself in the shoes or boots of a forest for the day oh hi im the new guy here grading the forest. Talk to your hike leader ready to go into the woods not like that get your boots on. Ok but. This is there. Much more momentum. The lines im slowly but surely create as turning into a force that some 1st like. The risks here are tripping over a root being attacked by boards and being hit by a tree theyre a threat to everyone in a forest i dont think most people trolling here know that true could be. A model but you shouldnt be able to see through a healthy tree so this goes into good even though you might think im not everything so green oh nice. This ones not doing got it all figured god not at all i dont recover either its completely dead now the single leaf left the bar just burst open. Whats this is that you know this is dust from the beatles who have truly their way inside they already inside their words even insects that are already inside the tree if you look a little higher you can see the drill holes where they are out in and the indents from a woodpecker looking for larvae. What do we do with this guy it has to be felled this one to. This one definitely means family. How long do these trees usually live a little book on the beech tree can live up to 400 years you have been under 400 years and these trees are over 150 years old. So obviously its getting dangerous ill go in alone its good idea. Id rather not go in than. Go. Come come come. Across as honest being a force as lovely im sure but im a bit scared of these bourse and the huge shift in the male looks aggressive and they are all on high alert because of the babies the mom is really looking up to see here they are now. Look at the goddess tusks super shop. Best day off again. Hes driving them on. The boss was. Very good. Oh. Its all about the swing you need proper momentum this isnt a name fight its an axe so ill swing swaying swing its very. Very. Well. I have a blister no one cares. So were cutting wood its easy. And i think i look pretty good doing it but. Jokes aside it is tiring imagine having to cut in of wood to heat your home for the winter. And i get blisters easily yes and i know hes won. Its proper work. For what ive wanted to be a forester since i was in 1st grade but its always been my dream and i found my dream job im living it. What about the next generati
