the, the key that is is that the news was what in the world of sustainability. hello and welcome. i'm sorry because the body and you are watching e going to clean energy is the future for sure. but what about its own future? it's life with challenges and opportunities as the was demand for energy increases . we are still not able to produce enough energy to he knew been sol,

she's yes. but why is it sold and how can we change that? some of the logo has been of, through, i'm trying to and you know, but energy making a head start in 1986. the state has used it's favorable, wind back to us to generate substantial energy over the mulatto host. one of these . yes, largest wind farms and accounts for 25 percent of in the store to wind energy generation . sounds great, but what's really behind these positive headlines and are things as rosie sbc abundance sunshine instead of events that we know do has plenty of. but the state has hon. is this potential to become a leader in genuine energy in india? a key initiative is the chief ministers, sol, up our green scheme. we check with low income homes, with solar panels aiming to make them energy independence. sheesh, however,

in summer not do followed has been a contentious issue for tickets. uninstalled a lady i said, have been facing the brand to frequent our cuts since the 19 ninety's. these outages have been driven by coal shortages, the losing adding capacity and group management districts in the fall cards alike, festivals, unpredictable. but everyone or just the should do let on when i go and not have to sometimes be have no electricity for 5 or 15. did a long fall, but got student greens, city, and at night we don't have the bible for many hours. so in recent years, the government has been focusing on electrifying villages, which venue will energy to ensure a consistent energy access. what is this actually making local communities self sufficient? i decided to dig deeper and find out what's behind this on the promise. i'm so a driving to about 520 kilometers from jenae to odin. today. this router lady, i has the receipts international asleep for being

a self reliant monte village. but due to neglect that annual energy systems has come down a decade later, it's computed economically and viable. i'm not even a single house here. is energy independent. i was did some of them who for 10 years said as the president of the punch i it, that is the village council. and for the next 10 years, he assisted his wife would have gone through this move to become energy independent with renewable energy. was his brain to see him following the village through aviation street lights and drinking water plants which increase the village electricity bills amounting to doubled up on sides funds. so he began looking into alternative means of energy. 2001 live in 2001 we introduce solar powered street lights, the guardians option by 5. by the same way, almost yes, very, by almost got suffice. covered 50 percent of our probably for a few years. and those things that will be brought to

a high capacity sources like wind turbines. then i have the government with green homes completed, which all up on this, making us more energy independent operating through the scheme. so last time is were predicted, the rooftop. the energy generated was been stored in by trees, which followed the household. davy was 56 years old phone me the calls to be she moved into her faith went home proudly powered by so lot energy does on the floor that we had solar power for about one and a half years, but then it stopped working. but we tried getting the back to the beard and even had to come and me come and check it. nothing looked i visited the cutting quintile leader to understand the speed is now still going to be able to rely on the solar poverty for all the needs. really, on this all of the, over the years the government has given people, feet of use, refrigerators and washing machine has started. so the energy demand has risen and i want to be able to get to the bottom. those don't have the capacity to buy with the

and so instead people rely on conventional power from the grid. having started system and we contacted the paperless since designated by the state to investigate any complaints regarding the solar panels and battery storage. people complain that we think we are started backing started system stopped working. now when we spoke to technicians in oceans, the fact that the reasons for this failure, one, the government did not have a proper maintenance done in place to the local community was not educated about upkeep or capacity on 3 once the photo up. so down there were no follow up checks done to assess energy demand and usage. as people began using more appliances, the existing solar panels were in sufficient. the people said they couldn't afford upgrading this last system or battery storage. let me know the consistent follow could help small businesses that i found most could use more than navigation systems. local shops could stay open longer and it would support

education. the villages said they expected that badge of energy independence to improve the economic status, but not having reliable access to power as actually there is definitely one day many here, ideally, pers funded about what to do. it has to be no economic development in this area. for us, a department that i'm going to explain to me is a question. can be self sufficient by producing enough energy for them that will be no need to rely on the claim. and only then when they use the defendants, encore, the follow up lines know, seminar, those, and those the transition is also highly politicized. power shortages and the debt to didn't electricity department a b, p link to political agendas, or major bobby's problem is 100. the owners of electricity as a long standing boat bank tactic, even though it takes a severe financial tool on the electricity department party and they'll do transition research says that there are

a lot of people who don't need the subsidy and this needs to be evaluated. i wouldn't say it's for you like this, a good subsidize electricity. the costs are benefit of that as being given is a, this is absorbed by the discount through financial losses on it is being cut off subsidized in any of the high piping consumers. and so, but i think it should also be more targeted in terms of who requested guntee guide engineer with the department added to the steve needs to focus on reducing energy to months in order to make this transition truly sustainable along the months. and they nearly 3.5 megawatt. it is a lot of fun, nearly 10 religious parts to use for the jewelry mater to work up to 11 o'clock in the day because that having your money, they have that april then and you know, it is, then you cannot save in. redmond, i visited the office of the state electricity department, but didn't meet the senior officials. i made several calls, but didn't get an answer. the states public exemption is expected to go by 60 percent by 2030. the state plans to meet 50 percent of the store,

the energy demand with valuable energy. sure. somebody know the space. what, what does the states needs to make this more sustainable? one integrates so a lot and then the energy into the grid to insurance. the ability to re evaluate electricity subsidies to make the move down to 3 includes rooftop solar panels, micro goods and community solar projects in google areas, to reduce dependents on expensive centralized students. solutions like back trees, full, actively involved local communities, to foster sense of ownership and create job opportunities to is it a new bill? energy story is a global cost of the, highlighting the need for better planning and maintenance. yep. what's in spiting is the 5th commitment to beginning the idea of energy with a fresh outlook and the department designated to look into audio. the future does look like i'm going sort of uh what is often seen as

a seen um sustainable alternative for odd energy. but what happens when solar panels age and stop working efficient? the international, viewable energy agency estimates that by 20 to see the amount of photo workspace waste in the was with cross about 78000000 done. and what, what do we do with orders to see that type of northern germany? let us for the farm is trying to address this issue more and more. so the funds are being built and the getting bigger and bigger. but photovoltaic cells become less effective as the age to break. like here in northern germany, this solar farm is only 14 years old. the, the ssl to grow couldn't. and that broke out because they went installed properly. plus one kid wouldn't. so the old panels have to be removed. 1600. often the

operators could have sending them abroad the recycling, but they decided we all want to get in and we don't have the ability in gym and you're not far from here. well, it's about an hour and house drive away rather than half way around the world to make this against a village funds, the waste experts in the west and jim city of minster, a police more more. so the farm operate is a using domestic recyclers by the panama. they contain the loss of rec emergencies . and you can save a lot of energy if you use recycled material or fun come. it's also extremely important. it is to keep those recycled materials here in germany. so they can be used again by industry and food. if panels are exported to the same as another industry, as we lose them in a follow on, the reclaimed materials were reciting. it says that cold becoming increasingly important a year ago, writing set of a plant specifically to recycle photovoltaic panels. before that, it was nearly

a sideline for the company, which just recovered. it's a medium on glass. now they aimed to extract the additional commodities with more complex recycling procedures. no longer restricted to class and elementary. and we can also recover the other components in the modules from silicon and silver to carpet and they've all, we recover all these elements. and of course they all present different challenges, which we are very intentionally focused on with the way uh, within runs, april. got into this afternoon. yeah. styling is not doing it alone. a few 100 kilometers eastern hollow scientist said the phone hoover institute, taking a closer look at the silicon powder for minute stuff. they've been working on how to recycle solar panels for a long time. now it isn't the 0 here still contains so fragmented by impulsively small amounts of metal contaminants in your minium couple for example, or element even from the frame. we want to recover them up to

a certain point. this process is mechanical here too. but the research just kind of when you get so far with that, when you're ready to get to the remaining components, you have to dissolve them chemically like in this lovely blue solution, see the silver can be precipitated from this solution. it's the silverware off the time that it works, but not yet. from an industrial scale. some startups and companies are now entering the solar panel, recycling business. there's a bit of a silver rush going on and doesn't always get into that. we have about $18000000.00 metric tons of solar panels around the world. if we do the math. so that's about $30000.00 tons of silver that can be recovered. doesn't look like that's an opportunity, male or female. just given kinda the song scheme of things and getting nothing about the recycling of photovoltaics panels. it's worthwhile for a number of reasons. and it could become a central part of, of mining the extraction of commodities from junk island medium. it's already working smoothly for gloves. separation process is becoming more refined,

so its quality is also set to improve. writing is optimistic, his business will grow and replace the old panels with new ones really pays off, as we can see back up the solar farm in northern germany. the i looked at the latest technology is so good, we only need a piece of the area to make the same amount of electricity that will lead to a rise in scrapped panels in india to. but with a lapse of folks of all techs only took off the from 2010 and 2020 feet in the as domestic passenger traffic page. or is that what high or over 150000000 passengers? and that means a lot of fuel consumption. so what do we do? we either saw flying or figure out ways to take the slice without using fuse that's comes from binding fossil fuels that's been done for the supplement back from

biofuels to hydrogen to electric claims. innovation is taking off quite a bit. so let's explore the future of seen those guys. it will surprise you to hear that how we fly to the needs to change. what is the most promising solution. so a vision for you sion, a biofuels more broadly sustainable aviation fuels. they're mostly made from non petroleum products like bio mass. so again, you can basically just swap the fossil fuels and heal for biofuels. i'll make a blend, but we need so much of it. the scaling up is very hot and the land could be used for other purposes, like drawing fluid or saving far. and then there's also hydrogen that shrink on this, especially hydrogen made sustainably, a lot of prototypes are being tested. electric plans are a 3rd option and they can make a really compelling case here where we never, we, we run off hydro power or wind power. so then to consider we have is sustainable and renewable. so for us that's, that's the,

the most sustainable we can do. right now, so the for us, this is you on know, but as going of a, the issue and one of the only people flying airplanes every day. when an a v, as in school, in sweden with future pilots are being changed and flying electric plants. the paper streaming bell as they fly here. it doesn't mean much electricity. it takes around an hour and a half to charge on which has been 545 minutes. but the result of 30 percent patchy is mostly use the pilot training or private key get faster tasks to get in. so hoss 1st as easy as i'm ready, correct? i've got the as fast this is a super light plane, but it can only go to people with no have luggage to go. any bigger

e plans are faced with a big problem. heavy batteries blowing, 747 to fly from say, london to istanbul. batteries will need to be based much heavier than a full time. this just going to work, since this wouldn't be 10 times heavier than the heaviest payload ever lifted. so governments and many of the industrial going back to the drawing board to redesign this is dawn. but in a vision expert who looks at on the ground infrastructure to support the transition by working together with detroit. but we looked at 2 main modes of operation for doing that one, which was a battery charging system, so where the battery would remain fixed within the craft. you would plug it in as if you would like a normal device. you would just charge it. this would be the simplest way operationally speaking, but they also found the charging with waste precious time. when current ed traffic relies on a quick don't around fans, wood ok by limited space in the airport. and of course,

the amount of power needed would take away significantly from the cities grid. the 2nd mode of operation we looked at was a battery swapping system. and that would be where you would have pre charged x rays. and then when an across came in, you would remove the battery from the frame and then swap it with the one that already been pre charged. this would save space and time, but it would require a lot of specialization that was required and you don't have anywhere. and it wouldn't be a big risk. meddling with an airframe is always dangerous. and there's also the major risk of files from holding so many batteries in one place. this is filled with the 1st plans to be certified, but this is another huge shot and what a vision has compared to cause being certified for safety. so everything takes time for r, n d testing and tony for battery safety and the use long certification process. the urban solomon bush for the idea of multi plans for shot in mid range flights. this is part of a while ago to got 90 percent of emissions from transport by 2050. all right. thank

you. all those crazy sit on the equity. okay. the back company than me that the district is now working on a full see the plane and the already bigger ones, a plane called alice secretary, 9 passenger. the 2 crew members seems to be close to commercialization, promising to fly around $400.00 to on it does. that's good, gary headed the app. what's program at the u. s. department of energy use national renewable energy lab. when you look at, if you think about their existing cargo routes that use small aircraft, their existing communities, that they're only connection is a, as a 9 senior crap unless they take a ferry for or 6 hours type of situation. and those are real existing route that have to be either subsidized or paid for by by communities. this is the main application so far, and it is significant at ambulances, at taxis and small cargo plans also need only small across the child has ordered 12

plants for low emissions post of deliveries, which can help local noise and equity to a study by the international central and team aviation estimates the electric aircraft called govern 9 percent of the coming to markets. that's flights with more than 19 passengers and distances shorter than 500 kilometers. but there's only a constant 0.002 percent of globalization. by 2050, the estimated could be up to 0.2 percent, which is still small. what am i talking about carbon emissions. but this is purely electric. we're talking about you could also have versions of hybrid. so you could have a series hybrid which is where essentially fuel is used to power an electric my to which then powers the aircraft the using fuel to charge a battery. essentially, the idea estimates of hybrids would be the next leap,

navigation to the 2030. and this will contribute to a 40 percent reduction and emissions by 2050 long flights and most likely use biofuels with some parts of the plane electrified. and some use of hydrogen. that proficient is a small step, but it gives us hope for the potential of the diversity of technologies that are going to need the a home sweet home. well, not so much for the planets around the world. we have gone to list or buildings that are willis energy efficient than the new ones. however, constructing a new building requires so much energy that it takes a long, long time to offset the best. oh, well, is there any way to to order building can come very close to matching the energy efficiency of a new one. but transforming and we're building into a sustainable home that takes someone's special new design into making. it's one an older house to make it a bit more sustainable. janae based architect unable model and drawn,

transforms existing on sustainable buildings into sustainable bonds. a green consolation. the reason why we advocate green john summations is because you can retain the building and you can actually more define the demolition of the building . again, there's a lot of positions, right? and what do you do with this demolition based? and it takes much longer for the or not say so, but reading demolition can you do this will probably take me to you as to what says a john, summation for the any it could be as a last 6 months. the green consummation process is different for each building and depends on what's needed. this residential home into night was transformed into a green building by an open mind and her team. for this house, all the lights and fence locked and loaded into energy efficient models. by what the toilet technology, windows sizes,

but increased to let an adequate natural light. and the introduction of cross ventilation means the occupants now don't have to use their ac quite so often. of all this helps to save energy, the water. what they do is, uh the, again, do please, all of the plumbing fixtures, the little flu fixtures, right? so it's a, do a slash water, placid, or adapt that have a new fluid it. so that reduces that initial water consumption and water will waste water that com. so we make sure that is treated, collected treated energy used inside the site. it seems a green consummation, like this one gets water consumption by at least half and reduces energy use by around 30 percent. the idea would be to apply this green dress summation process more lightly. but do you know, mega city like 10 i that's not without its challenges most notably,

the cost costing uh, with a green transmission really depends on what we do. so yeah, i would say between, you know, 15 to 30 last or so as long as you can get most of the, you know, this is the interesting thing done within that, that's between 17 and 33000. utah is an affordable for many, but senior green building consultant, critical to christian and sees these green transformations could still bring about v a change. this is done phones and translates into a visit. that is uh tangible. people can feel that they can see the and noisy deduction in their bows. they can see the what the savings in their house. they can see that the friends that are mixed to their environment it's, it's a huge thing to lease annually, but sustainable public building,

designed by unemployment, could help save the weight for new standards, increasing q one and award from the indian green building concept for being the nation's most sustainable government building. it's an integrated come on center for the city of to night. and on simply as the green building. it is an extension of the ship on building, which is a public heritage facility, posting the offices of the local government for the city of to night. the come on center and a green volk with that connected with the group on building what designed by under bama and her team. jenn, i city government wants to upgrade all government buildings to meet environmental standards as soon as possible, as one of the chief engineer explains being the environmentally sustainable. and also what you're trying to plant is the 0. well, i've been footprint. that is the main idea. and we are also trying to a,

to the existing building also the disability and all the. 1 existing buildings to be converted to building standards, the to look good stuff to be like 10 it is so many building. i mean is building the home. i will say 99 percent on not just the mean, john summation not only to this one flag, but if you're able to you know, influence. many such buildings is very, very excessive. as we've seen today, the future of clean energy course. immense promise. a new innovations can really help us stack of the challenges if we face. thank you for joining us. i will see you next week. let us know what, what do you like to see more of on the show. you can email us or reach out to me directly on my social media. hundreds until then daycare goodbyes, soft gosh,
