yours revealed the future is being determined now, our documentary theory will show you how people, companies and countries are rethinking everything and making major changes. you have revealed this week on d, w. d. ah, nature overs us many resources, but we don't always use them optimally. sun and the wind are abundant. so how can we harness them cleverly? welcome to a new edition of equal africa, environment magazine. here in camp along uganda, i am sandra trina, and oh,

whoa, whoa, come from me, chris alone. in oakland state nigeria. sometimes we can learn from the past. our ancestors knew pretty well all to farm sustainably. but 1st, let's look forward. this is what's coming up and the next 30 minute ah, all you can charge your cellphone on your own sweeter. hall, green is solar energy really? and farmers returning to an ancient methods to feed your cattle it happened to all of us. you're sitting with your family having dinner and all of a sudden the lights go out par failure. hey mike, jerry, it's unfortunately our daily occurrence for a lot of people. only about 56 percent of nigerians are connected to the national

park grid and it's on reliable, on average in i drove home gets about 5 hours of electricity per day. but because of our proximity to the equator, we have intense energy coming from the sun. how we can harness it effectively, independent off the national park grid is a focus of this next report from bum bum in august state. with this welding torch is running on electricity, while at the same time, mobile phones are charging on the headrest. the next bill is running a fact. a few years ago, this would have been impossible for the people who mammogram in the state of the village wasn't connected to any power. great. now it has its own small solar power . the 8 to 5 kilowatt peak plum. that is, sarah,

not only does 2000 cipher households, but also people, but all saw we have are both 100 products use use us. are both territory commercial users on also 30 public renewable energy has made the entire village, independent of the public. great mammogram is one of around 100 communities benefiting from the nigerian energy support program. the project receives financial support from germany and the local companies build and offering the plans for the major any support program commission by the repeal human and the german for graham reduced fee for economy corporation and development has helped deny dram people. in many ways we supported major ali, the renewable energy, energy efficiency, or education measures of the country. and we've given 30000 people are so silly

tricity in this part of nigeria, solar energy has proved that you can use the local economy. grocers can refrigerate their goods and sell them over a longer period treats people can work more relying as they are no longer dependent on gas power generators and macs. it transport company from league us as owners will set up shop here. it's developed on the bank that's able to handle conditions or nature else, routes. its rental station is located right next to the solar power. these people don't have rude networks, an access to fuel station. so, um, setting up the charging infrastructure for these vehicles, right, in the heart of the call, nancy already saves them time on their models are discussed. i do have to over to get par for the vehicles. that house, you know, tremendous impact on time. save in that australia's impact level security. many

villages are still skeptical, acknowledged. that's why max stress is the environmental friendliness. when marketing his bikes, the fundamental difference is just also accomplish on engines that pollutes the environments max spent, you know, according to time with the members of this community, training them on how to use this, this vehicles, or how to get used to, oh, how quiet the r fam, i d need you down to is a fan of the bikes and now uses them for deliveries. the rising cost of gas was another factor in his decision to switch to an invite, which course seemed between $501000.00 there a per day. roughly. wanted to yours to lucy richie. you know, how do we solve power has brought prosperity to our communities, or more people who can now use light, z televisions and freezers. and we now have, well, those who can use solar power to do their work. so we don't have to travel far for

such what religious sheila moms may be success story, but he can't disguise the fact that nigeria has a serious energy problem, often only a fraction of its existing capacities being used due to technical problems and acts of sabotage. the result, 55 percent of the population has no access to electricity. and that is the problem in a direct keeps on rising dark places that day not ad assisted the national grid for one and 20 is touchy. yeah, i didn't depend it on for the for dinner, jane idea which caused a lot of money. so renewable energy, easy solution to our problem in nigeria, new when i didn't dawn into right, we really damina shalaya trains specialists in sooner. technology. more than $5000.00 nigerians are taking courses at washed them or cut him like a lot of the niger and energy support program. they're free of charge and

a shalaya says her graduates have good jo process. we need more person out there that i killed enough to solve our energy for what a possible event about different types of companies in id hadn't let about how she did a bag full. i resources how to do basic solar installation out you out to the maintenance and troubleshooting of the last is days. graduates from the academy to the maintenance on bumble by masula contract, helping make the village a really model for renewable energy natured. by next year, the government plans to supply, if further 100000 people with electricity from clean energy sources, morsel a power plant would certainly help a lot of people here in nigeria. and they don't always have to be huge. solar

energy can also be very useful on a small scale. one student from kenya came up with an ingenious idea for how to reach our devices, such as cell phones, do an entirely without par banks or electricity from the grid. let's find out more in this weeks. go in your bits. ah, b, there is no shortage of sunshine in kenya. a graduate of university of nearby has developed a device that you the solar power to charge cellphones and produce light and is attached to a hoodie. it's supposed to be so. oh, i do electrical engineering. alamo, where all my foul way are both are being executed. so i must make my thief with her is the letter. for that it is the letter. and now what a proof. they cannot,

i electrocute invoice. another thing, ah, it 1st, because if i follow ruge, calhoun imports the materials to make the hoodies the minis. solar pour system is put in place on the hoodie and then covered up with an easy to remove seal. this is connected to a fawn charging cable. his customers, as students with limited access to electricity alone, when i enter has just bought himself a cultural design. i really feel cool. i feel like, oh, i feel like with a i haven't seen anyone else with something like this. if he thought i'd given

me that, i mean like i'm living in 20 that she coupled celsius hoodies for the equivalent of 49 euros. he's hoping he will soon be able to expand his business beyond nairobi. and how about a year? if you are also doing your best, tell us about is visit our website, go send us a tweet, hash tag doing your best. we share your stories. what a fantastic idea are global, who they like that? it's a small skill example of our technology that has been adopted worldwide in huge solar farms which supply energy to and kyle regents. let is very to crease. of course the solar panels have to be produced. and that requires some toxic materials like

lit. and what about the old panels? can they be recycled? how green either solar energy reading or reporter took a look and found out it's emissions free? that's why solar energy is said to be so green. but is that really true? let's have a closer look at the 3 critical issues surrounding solar energy. first, let's look at what impact solar energy has on the climate. i. solar panels produce electricity without creating emissions. but producing them uses lots of energy. raw materials have to be mind transported, processed, then the whole thing has to be assembled. and as our economy is still largely run on fossil fuel, all this means greenhouse gas emissions. so the question is, how much and how much is that compared to other sources of energy?

and evaluation revealed the following results. on average solar energy emits around 40 grams of c o 2 equivalent per kilowatt hour it produces, which is really low compared to fossil fuels like natural gas at 500 grams for coal at a 1000. in future, there might even be completely new solar technologies, like probe, skype modules. these promised to use less energy in production and convert even more sunlight into electricity than that would create a kind of snowball effect. the more solar gets deployed, the cleaner it will become to produce even more. so strictly speaking, solar energy isn't completely emissions free, but it is already one of the climate friendliest energy sources we have. next up, let's take a look at what actually goes into making all these panels to produce solar cells. you need quite a few chemical substances like silicon tetra, chloride. for example,

if it ends up in the water, it can have devastating effects on the environment and people's health. it can be recycled and then reuse. but it's unclear how many manufacturers do that. we have a lot of hazardous chemicals of concern that are in east in to make solar panels. the coalition developed the solar scorecard that ranks manufacturers by their sustainability that ah, pretty much ah, the problem, what's solar? so it is green. it's only green in one phase, wanna make sure it's green throughout his life like, ah, zina li, let's take a look at where all these panels go to die. solar panels last around 30 years. as of now, the waste heap of discarded panels is still relatively low about 250000 metric tons . but by 2050, it's expected to grow to 78000000 metric tons. that would be more than $200.00

empire state buildings of old solar panels. up, you know, now it's a, we can see that it's going to be a problem that, of course, and in the next 10 years or 15 years is going to be a major crisis. where old panels would pile on to the mountains of the waste. we're already struggling to deal with, but there is a solution, recycling the panels, governments in the european union, for example, made it compulsory for manufacturers to make sure they're used panels get recycled . but still not all of the materials can be used to make new solar panels. and the cost of recycling is relatively high. and that's partially at least because there's not yet that many modules to recycle. this means in places without legislation, like the usa or china, it's still cheaper to throw old modules into landfills. a french start up came up

with a new recycling process focusing on recovering the most valuable materials. actually, economic return of the class is not that high. so we try to integrate our so how much volume that has to be recycled. so silicon as silver ah, together it's about 3 percent of the total weight only. it has 17 but even with a 70 percent off the of the economic value. the company hopes to make a profit recovering the materials and then be able to build more solar panels. so for now, solar power is not entirely green, but the good news is that solar panels can be recycled and that it's actually worth it. protecting gal environment means we have to keep improving the technologies, ways and one month in the netherlands is doing exactly that. agriculture and

forestry are responsible for almost a quarter of global cub, wendy oxide emissions. but we're making green houses more green these entropy. noah is aiming to make them more climate friendly, event, climate neutral. these are the green houses of pito mining in 4 years. his obsession has been to run them as environmentally friendly as possible. he specializes in sweet peppers and cucumbers and produces huge amounts of these vegetables and toto our company. us is 50, hector. yes, and on the 15th, as we grow 32 hectic sweets pappas and what we have as well is as long as we come, are that you can see here as we grow them about 30000000 pieces a year. it's a complex and finely tuned operation. in all aspects of growing feeding and harvesting the produce and behind it is an elaborate system of energy production

using as little energy from the grid as possible. like this is the transport system . but this is also the heating system that this is a pipe. and we put in, for example, $55.00 degrees of water, the hot water from the biomass bomb, for example, us each be combined heat power can go into the greenhouse. and during the night, the roof is shielded by retractable blinds, to keep in the heat, which again, saves energy. this is a 20 cylinder 3 megawatt electricity, and which is provided by the yellow tube is gas. and then the machine is running, making 3 megawatts electricity, and producing to cool it down 3.3 megawatt to make. and that's the energy how we used to heat our greenhouses. his real pride and joy is his biomass plan, which recycled local greenways,

including the stocks of his own vegetables. it's mainly chips from the area. and like this truck is also coming from the area it's collected, it's only to, that's what i. so how does that work? yeah, the biomass comes from up, falls down on the grades, and then afterwards, everything is cleaned. and on top, with the heat, we make steam. with steam, we make electricity. to do the big systems energy generation, peter invested 30000000 euros is some only larger companies can afford will remain in europe for the time being, but sweet from the height to lot take in france. severe heat waves, ongoing drought, or destroying colds. and the land used for grazing to feed his cattle. one farmer has revived an age old tradition used by his grandfather, which as it turns out, is surprisingly effective. 2022 was the hottest summer ever recorded in

europe. many regions have little rain for months, rivers, streams, and lakes dried up. even major waterways like the la river and france were reduced to a trickle. french farmers where it had particularly hard by the drought crops, shriveled on the fields and pastures baked in the sun, leading cattle with little food to eat. in desperation, farmers turned to a nearly forgotten source of food, the leaves and branches of trees. in the friend of us trees there like insurance against drought. they've been here since before. my grandfather bought the land in 1939. most of them were planted here since they grew quite well joe, we prefer prefer through the mongrel composition is a farming method that has existed in europe for thousands of years. trees are cut back on a regular cycle and the stems and branches are used as cattle feed. for decades,

there was plenty of rain and grazing land here, so copying fell into disuse. now recurring drought is reviving the tradition of america instead call this year, which was dry. i don't know how many we proven we produce a lot of them on several 100. a bow made of the near on ash tree like the one we've just cut back will feed about 6 to 8 cose. he sees you. you are. there were days that summer where we had to corpus several trees. sometimes up to 10 on approved with the trees or a big money saver for farmer chris jumble nut. he estimates it saved him from having to order 2 truckloads of hey this year without the ash trees, he would have spent about $7000.00 euros on hayes. ah no name on there. i know here we turned the nash tree to make fodder. we made a bundle or to that which we are going to try for fishy. we'll give it to the

calves when they're a month, a month and a half old netflix is on one. we like the crunchy leaves in the spring for ca, zebra. so, um, ah, this ash trees were planted for copying long ago today cuz jambo linelle is bringing these branches into storage to feed his cattle in the winter and in times of drought. he's benefiting from the wisdom of generations of farmers who knew that as the saying goes, only a full cow is a happy cow. ah, no, we had but to africa. well, we'll also have a long tradition of knowledge the we can use to help in the fight against climate change in zimbabwe. perform a z, as in nancy, ease bringing these ideas to the stage. does right, sandra it is a one man show in ya see investigates the road for this. the knowledge systems and

signs play, either fast changing world and in climate change intervention. take a look. i to go mess with ha! all actors enzo naughty gives the suffering earth a voice. he also plays a farmer who leads in oxen to plow across tough soil, who taught, who took it out to him. oh, the actor uses comedy and drama to teach children about climate change and environmental protection. the story and act of man is about the life of a rainmaker who's lost his powers. the work was specifically conceived with children in mind. oh, how can humans survive famines and droughts? to answer that question, the actor also plays the role of

a scientist. i feel that it table was with tele, plumbing when cisco made a fool the so gum that they won't grade that the whole walk on monday and love the kids seem to be getting the message, especially the part about humans needing to act quickly. i learned that there and then never came in wednesday and i lent also house who also enjoy myself. i met pants, ease and tell everybody to and keith, for the teachers. the show is a welcome addition to the lessons in which they emphasize the importance of environmental protection. it is important to incorporate that into our an ad aspect and doing a performing at performance because they understand it more so it's out of their formal education in class. the tour started into smaller cities. now,

since only athey is performing in the capitol herrera, the actor developed the show and just 7 weeks, he's been involved with climate protection for a while now. for his 2nd job. as a farmer, he uses climate friendly farming methods on his own land. said dish no learned systems late at all in the past. yes. in that science ease playing a role now, but how best can we make these 2 is specially containing issues of climate change to keep a don't center change. the topic is presented with a touch of humor, but it quickly get serious one b, and b of me coming from the doctor for the day that we have in prison for either cindy or just it in your system. and you, for the show's creators, hope that the performance serves as an example to others. what you really like to

see is to, to excite other people, particular young actors where they can actually say, i want to do the same play so that it continues being done over and over again by quite a number of people. we are happy that we have talked people that have the know how and we are hoping that by poking them instead of them doing a lot of discussions, there would be more action around issues of climate change. his own contribution is the show. if he's able to acquire financial backing your performance in all of zimbabwe, 11 provinces, there are so many eco friendly solutions and initiatives out there. we hope you enjoyed the show. i'm chris, the lamps from morgan state nigeria till it again next week. and if you want to find out more, don't forget to check us out on our social media platforms. we'll be back with

another new edition of africa next week. it is a good buy from me, sandra to nobody here in cumberland, uganda, a, [000:00:00;00] a ah,
