the nice so maybe we all because like instead of the clean energy, is it the new was what in the world of sustainability. hello and welcome. i'm so i think that the body and you're all 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 e g 's is we are still not able to produce enough energy. so he knew open source is

yes. but why is it sold? and how can we change that? mulatto has been of, from china in june. we've been energy making a head start in 1986. the state has used its favorable window patterns to generate substantial energy over the years. i'm allowed to host one of these you as largest wind farms and accounts for 25 percent of in the store to win the energy generation . sounds great, but what's really behind these positive headlines and our teams as rosie sbc, as abundant sunshine instead of events that we know do has plenty of both. the state has hon. is this potential to become a leader in genuine energy in india? a key initiative is the chief minister sold up our green scheme. we check with low income homes, with solar panels aiming to make them energy independent. however,

in summer not who followed has been a contentious issue for tickets. uninstalled a lady i said have been facing the brunt of frequent advocates since the 19 ninety's. these outages have been driven by coal shortages, the using adding device a d. i'm group management issue in the fall guts like festivals, unpredictable but everyone or just the should do that on or not or not. and sometimes we have no electricity for 5 hours and 50. didn't go on public, got student screens 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. but as 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 received 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 on 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 check? let's see, i'm following the village through education street lights and drinking water plants which increase the village electricity bill is amounting to doubled up on sides funds. so he began looking into alternative means of energy. 2001 live in 2001. we introduced sola by what street lights, gardening, and junction by 5 percent. and once again, i almost got safire covered 50 percent of our power bill for a few years. and those things that won't be brought to the high capacity sources,

like wind turbines, then i have the government with green homes. it's all up on this, making us more energy independent operating through the scheme. so last time is we're 50 to the rooftops. the energy generated was been stored in by trees, which followed the household. davy was 56 years old, formerly the calls to be she moved into her feet. milton, proudly powered by so light energy down to florida. 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 gutting quintile leader. to understand the state is now still going to be able to rely on the solar offered 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 this part. so the energy demand has risen in 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've been to we are the backing started system stopped working now when we spoke to technicians and also shows 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 capacity, i'm sorry. what is the photo up so don't? there are no follow up checks done to assess energy demand and usage. as people began using more appliances, the existing solar panels were insufficient. the people said they couldn't afford upgrading this last system or battery storage. let me know the consistence i work with head small businesses that i find most could use more than navigation systems. lucas shops could stay open

longer and it would support education. the villages said they expected their badge of energy independence to improve their economic status, but not having reliable access to power has actually, there is definitely one day many here, ideally, pers funded about what typically it has to be no economic development in this area for us a department that i'm going to explain to me is a person can be self sufficient by producing enough energy for them that will be no need to rely on to connect with them and only then when they use the defendants, encore, the follow up lines. know some of 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 parties problem is 100 the owners of electricity as a long standing boot bank tactic. even though it takes a severe financial tool on the electricity department already and they'll do transition research says that that

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 better because 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 product wise, it's gonna be died engineer with the department added to the steve needs to focus on reducing energy demands in order to make this transition truly sustainable along the months. and they nearly to 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 within and know you do, then you cannot save in. redmond, i visited the office of the state electricity department, but couldn't meet the senior officials. i made several calls, but didn't get an answer. the states public exemption is expected to grow by 50 percent by 2030. the state plans to meet 50 percent of the store,

the energy demand with valuable energy. sure. somebody not 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. so a lot of projects in july the us to reduce dependents on expensive centralized storage solutions like back trees, full, actively involved local communities to foster sense of ownership and create job opportunities. some of the ones that i knew, blak knew the story, is a global cost of the, highlighting the need for better planning and maintenance. yep. what's inspiring is the 5th commitment to obtaining 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 energy agency estimates that by 2016, the amount of photo workspace waste in the was crossed about 78000000 times. 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 photo voltaic 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 whole panel would have to be removed $1600.00. often

the operators could have sent them abroad the recycling, but they decided they are going to get in. and we don't have the ability in gym and he's not far from here. wow, that's about an hour and house drive away, profit and half way around the world. and there's a bunch of other funds the waste textbooks 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 a looked over at commodities and you can save a lot of energy if you use recycled material or fund company. it's also extremely important. it is to keep those recycled materials here in germany. so they can be used again by industry, and if panels are exported to the same as in other industries, we lose them in i'll follow on the reclaimed materials recycle. 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 a medium in class. now they aimed to extract the additional commodities with more complex reciting procedures. no longer restricted to glass than the menu. we can also recover the other components in the modules from silicon and silver to come out and say, well, we recover all these elements. and of course they all present different challenges, which we are very intentionally focused on with the going uh, within runs april, got into this afternoon. yep. styling is not doing that alone. a few 100 kilometers eastern, hollow scientists at the phone. who for institute a 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. no, it isn't much. 00 here still contains so fragmented by impulsively small amounts of metal contaminants in your minium copper, for example, or alam indian 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 the solution. it's the silverware off the time that it works, but not yet. on 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 tons of silver that can be recovered, doesn't look like that. and they'll put units email at the middle, just given kinda the theme 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 the 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 and northern germany. the other thing, the latest technology is so good, we only need a face 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 20 is when do you see in the as domestic passenger traffic tate, 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 save the slice without using fewer. that's comes from binding fossil fuels that's been done for the supplement back from biofuels to hydrogen. so electrically innovation is taking off quite let soon

. 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, pollution of biofuels, i'm overall the sustainable aviation fuels. they're mostly made from non petroleum products like biome on so out 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 fluids of saving far. and then there's also hydrogen that shrink from 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 now have we, we run off hydro power or wind power. so then to consider we have is this sustainable renewable. so for us that's,

that's the demo sustainable. we can do right now for 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 with an a v, as in school in sweden, where future pilots are being chained and flying electric cleans the papers for the ballast. they fly here, it doesn't need much electricity. it takes around an hour and a half to charge on which has been slide 45 minutes. but the result of 30 percent patchy is mostly used for pilot training. a private key get faster tough to get in . so hoss 1st is easier i'm ready. all right, let's go the . 7 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 it's done with batteries will need to be based much heavier than a full time. this just going to work, since this would 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 bug and 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, you from the cities grid. the 2nd sort of mode of operation we looked at was a battery swapping system. a. and that would be way you would have pre charged x rays. and then when in that cross 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 shows what 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 our in the testing, including for battery safety and the use long certification process. the urban solomon bush for the idea of more e plans for shot and mid range flights. they just bought 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 company that means that the district is now working on a full cedar plan and the already big ones, a plane called olive secretary, 9 passenger, the dooku members seems to be close to commercialization, promising to fly around 400 kilometers. that's good, gary headed the apples program, but the us department of energy is 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 a 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

plans 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 market. so that's flights with more than 19 passengers and distances shorter than 500 kilometers. ready 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. we're not 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 uh, power has the aircraft. so you're using fuel to charge a battery. essentially, the estimates of hybrids would be the next leap,

navigation to the 2030s, 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 clean, 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 you're 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, then 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, the new 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, especially the new design in the 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 do it in the building and you can actually more define the demolition of the buildings . 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 to vote, reading demolition. can you do this? would probably take me to you as to do versus a johnson mission for the any. it could be, as i left the 6 months, the green consummation process is different for each building and defense on what's needed. this residential home into night was transformed into a green building by an open my and her team. for this house, all the lights and fence converted into energy efficient models, firewood that solar technology, window 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. all this helps to save energy, the water. what we do is uh the, again, to replace all of the plumbing fixtures. the last little fixtures, right? so it's a, do a slash water, placid, or adapts that have a new fluid it. so that reduces that initial water consumption and water will waste water that com. so let me make sure that is treated, collected treated energy was inside the site defense. 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 at least we can get most of the, you know, this today is the interesting thing done within that, that's between 17 and 33000. utilize an affordable for many. but senior green building consultant, critical to christian and sees these green transformations could still bring about 3 a change. i mean, if it is done phones and translates into a visit, that is uh, bend you. but people can feel they can see the and noisy deduction in their booth. they can see the water savings in their house. they can see that the friends that are mixed to their environment it's, it's a huge thing actually. a newly built 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 gen night and known 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 command center and a green volk me, that connected with the group on building what designed by under pama 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 engineers explains. being the environmentally sustainable and also what do i bring to plant as 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 existing buildings to be converted to building standards the to look good. the election, 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 does this one flat, but if you're able to you know, influence. many such buildings is very, very sensitive. as we've seen today, the future of clean energy, who is a mens 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 would 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 stick it goodbyes. soft gosh.
