One of the most expensive sources of Power Green Energy for the future a topic all made the use business short. 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 havent changed 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 lots of 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 would come the natural the money factor using green only Christmas Eve at this factory they say they can. Steel production is responsible for around 5 percent of global c o 2 emissions but here. They flash their output if the greenhouse gas. Is heigho. 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 yarn is then melted in the converter together with scrap metal to produce crude steel the finished product is he was to make such a steel girders burning hard cold limits in 2000 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 a new poll sources such as wind farms c o 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 dealers primarily from the surrounding who are finally region. And this is where its recycled the 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 alex tricity with a load of 61110000 volts generating a loss of heaves. 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 cabin this house has. Just added a special mixture of scrap steel and this is if 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 molten metal as he said to 17 or 1800 degrees so the cooling fails the furnace would melt itself and water and steel are not compatible. Once the melting process is over he were trucked 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 of furnace thats pretty rad so its exciting coming here every day and seeing the crew through material being tended to precede. The factory has 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 well be making it with Green Electricity. And the plants power consumption is enormous. Vaca needs as much Alec Christie as the entire time a victim seen in the background its population 100000 people. The continuous constant plans produces great steel in someone dies in different grades from bullet proof steel for limousines to a special bright scene for medical implants. The sort of Electric Company we have 90 to 100 minutes the tween tappings which means 13 or 14 batches per day and yet thats most of. Which in turn translates into around 1500. 00 tons of steel produced every day a product thats marketed under the green still able to do the lower and push of c o 2. A new smelting procedure every time kevin but its house prepares for a new batch its something of an event because most was a big motivation when i took on the job its pretty special. 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 Cambridge is crowdfunding 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 here its africa than it would do in germany for example and were 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 as sun 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 wed always that yeah kids were 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 nearly excitement and that is also what you want to teach children for the future isnt tipping nearly 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 weinbergs company developed an underwater pump powered by the ocean. As waves it turns 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. Us. For. There is 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 it 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 its an expensive system to develop when there is very little funding available so this is why its 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 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 big box met 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 that 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 its one that b. Banks is determined to make a reality for startups founders months or how many you know and 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 our customers on the ground are really striving to achieve locally. But you memetic college over 10 years ago together with their other partner the beginnings of the venture were modest as a student Charity Organisation the budding engineers vision to bring Solar Systems to remote areas and to link them up digitally you managed to get some funding from our own university from other sponsors as well and we were able to that some provided access to to some 60 households in a rural part of the rwanda and i think but at a time when 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 that trick 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 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 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 who invested in b. 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 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 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 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 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 thats 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 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 already been cut. With no thought for how much we owe them theyve given us life saving medicines paper course. And one of humanitys favorites. Have educated know this if you flew into germany youve 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 craig decided to put himself in the shoes or boots of a forest for the day. Oh hi im the new guy here masquerading as a forest. Tucker you go hike ready to go into the woods not like that get your boots on ok ok boss. Forced us to discuss that. Momentum. The lines im slowly but surely creak as turning into a force some 1st like. Regular lucky 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 crawling you know that is often true could be. A model but you shouldnt be able to see through a healthy beach tree so discordant good even though you might think im not everything so green oh nice. This one snuck it weve got it all good god not at all you dont recover either its completely dead now the single leaf left the bark has burst open. Whats this is it you know this is dust from the beatles who truly their way inside they already inside theyre worth it in 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 index from a woodpecker looking for larvae but. What do we do with this guy it has to be felled this one to. This one definitely not spelling most. How long do these trees usually live ill get a book on the beech tree can live up to 400 years when i got 400 years and these trees are over 150 years old. So i guess its getting dangerous ill go in alone. Good idea. Id rather not go and. Go. Come come come. Across as honest being a force just lovely im sure but im a bit scared of these bourse they use the maid looks aggressive and they are all on high alert because the babys mom is really looking up here they are now. Look at the super shop better they ought to get lost types you think hes driving them on. The boss definitely with his tusks its. Very good. Taking your hearts i would be opting out of the time 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 being on top. I have a blister no one cares. So were cutting wood its easy. And i think i dont pretty good doing it. Jokes aside it is tiring imagine having to cut enough woods to heat your home for the winter. Because i get blisters so easily yes and i know heres one. Thats 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 generation of forces. Luckily the Career Prospects are really good its always nice to have a grown up with it or shouldnt and im really proud that my daughter is studying forestry and maybe someday shell become a forester herself would feel like for some of the fact i mean. I think i cut quite a good figure ive proven my woodcutting credentials would you say ive 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 potential. Being a forest road which is a. Much for ever. With this i dont. It ruins your half dollar. Plus a tru t. V. Ban thanks for joining us today ill see you next.
