listening to. why are we greedy. we go in search of answers in a documentary film. starts may 21st w. hello welcome to eco india a sustainability vagas the bring you solutions to some of the most urgent problems affecting our planet our focus today is on renewable energy and how societies are transitioning of the from coal and fossil fuels for their daily needs that are who are coming to you from mumbai in india over the next 30 minutes let's look at how

far was the best pinball are saying move to be so i would german company has found a solution i mean we mean we saw what happened and how young engineers in berlin are creating their own wind turbine 1st let's head to the east of india in west bengal traditional farmers here like many regions around the country use diesel pumps to water their fields diesel is expensive and very polluting one company is helping them make the switch to energy on a g.e. is still sitting out solar water pumps in farms and even enabling the farmers to become water on the promoters. only rule. she's the 1st woman to install a solar farm in this willage after watering her fields of paddy rice potatoes mustard and wheat open up all sells the excess water to anyone who might be in need

in her village. that the plan to install a drip irrigation system nor water usage then we'll be able to grow flowers fruit and other vegetables. the villages 225 kilometers north of west bengal's capital kolkata these are good deals for the farmers here but a visit here during the last monsoons would have fainted a bleak picture frequent power cuts and the severe scarcity of water on most of these fields into dry wasteland spelling. do for the farmers. today's lush green harvest reveals a new development sees esky saline who deals in farm equipment in the region. i'll be working with the farmers and farming equipment and i would visit each of the homes and devices subsidized by the government some farmers storing there were

facing a water crisis and they complained about not getting enough electricity they asked me about solar energy they could use it to pump water said if they could utilize it for farming it would improve their life. the body. is the 1st religion the area to have made the switch from diesel to solar power what is it again the transition that has proved to be a boon for its farmers. from being able to grow only paddy rice once a year farmers like. to do practiced multi cropping all year round. only there were no arrangements for water here used to from using pumps. generators there were about the. or harvesters martineau it wasn't good enough.

selling proofs in solar panels phone story when i was here when they were 3 that must. have been able to grow them all in good quantities in the past farming cost us a lot more we used to spend about 40000 rupees on design of the card out the. truth . when the need arises farmers like margy now also have the option to buy water from local entrepreneurs like open up all. there is also another business model that has been successful and would you it's known as the joint liability group under which several farmers invest collectively in a pump the scheme is the brainchild of call qatar based company owner g.e. solar. focus. reinvestment because something like us already given bambrick was a lot of investment and this so basically what we did was we understood what the

only degree these were and we tried to could be enjoying globality groups awaiting their liability doesn't forward to one pharma it is basically an entire way 5 things from us we come together and then they pay for the entire system and that is how shared expenses can bring the cost down. on or g. was founded in 2009 as a spinoff of the ngo or switch on which works to promote environmental ed walker c. and sustainability across rural india since then the company has been developing solar lighting in off grid religious solar irrigation and solar rooftop solutions for board rule and urban communities working closely with banks to help and financing and with the government to ensure maximum return support on or g.e. has installed over 250 s. . solar micro grids and sold over 800 solar irrigation farms across india are

getting banks buy in so that they can start lending for solar pumps was very critical it was a very important quest abolition payback and financial viability for the sponsoring system and that's what was our objective to ensure that how farmers are able to repay the bank loans one through the savings in the diesel that they're not using and secondly by a big increase in their additional income as they're able to do multiple copies. at a price of a around 5000 euros a solar bomb is 25 times more expensive than a diesel power to pass a little of the shift away from diesel owner g.e. has developed a network of little entrepreneurs who provide the farmers with training and technical support they are already active in 5 indian states.

like an orgy of poor the solar powered systems have helped farmers in other villages to boost agricultural productivity and go with what is cassidy to improve their livelihoods. renewable sources of energy like solar but they are very fair vis a sustainable but how realistic is the goal to completely switch to this form of power generation next explain or else you want so that question. carbon rich and cheaply priced fossil fuels continue to dominate our global energy supply and. these resources however are finite. that means they exist in limited quantities and cannot be replenished in our lifetime. one solution would be to switch to renewables. but how realistic is the

goal of powering the world entirely with renewables. sources of renewable energy include wind bio gas solar and hydro. currently our level of dependence on fossil fuels is high accounting for about 79.5 percent of global energy demand while renewables account for just 10 percent. of. the burning fossil fuels contributes to climate change by releasing greenhouse gases this accounts for up to 89 percent of global carbon emissions. but shifting to renewable energy sources comes with its own challenges for one they're not always reliable. photovoltaic system is sealed on average about 20 watts per square meter when the sun is up. at night it's

a different matter. a fossil fuel burning power plant generates a 100 times more energy than a solar farm covering the same area and a 1000 times more than a wind farm with the same footprint harnessing renewables requires large amounts of land and that can come at the expense of local communities and natural ecosystems. they also necessitate the building of costly transmission lines when a solar or wind farm is located far from where the energy will be consumed. some countries however are in the process of switching to 100 percent renewables custer reka europe why and iceland. they are leading the way towards a future without greenhouse gas emissions thereby reducing pollution and conserving resources with the necessary investment and the right technology the transition to renewable energy is. hospital. now waste water

can be a source of energy a company in germany has come up with a method to not only clean beast water so that it can be but also to generate hydrogen hydrogen is a 0 emission fuel and can be used to power up these feasible is this let's fight. the big cities generate a lot of waste water. here in berlin much of it gets processed at this sewage treatment plant. it deals with the effluent of more than a 1000000 people a quarter of the city's population. the water passes through a series of filter beds. within a day 98 percent of the impurities are removed. nature deals with the other 2 percent after the water is fed back into the outside world. therefore we release the treated waste water we add

a lot of oxygen to make sure there's enough in our lakes and rivers for the fish and other life forms. as you can see it creates foam but only briefly it's entirely biological and it soon disappears over there is gone already. the process of purifying waste water is complex. samples are taken a various stages in the process for analysis in the plants lab. the water is brown because it contains lots of microorganisms more than 200 species that are added on purpose so they can do their job eat up dirt in the water. when they finish their work what's left over is sewage sludge. it's then fed into bio gas digesters. the gas that's produced their powers turbines to generate electricity to run the treatment plant.

what's then left over is process water which is still pretty dirty it can contain compounds that produce ammonia which is toxic to fish so this process water has to be purified some more. we use a biological process to clean out water we deploy specialist microorganisms different from the ones used in the 1st stage of the process. this 2nd treatment step is complex and expensive. that's why ganz hunger comes in. his company is developing techniques to improve the water purification process and make it cheaper. he uses samples from the treatment plant for experiments in his lab.

for him wastewater is a resource a raw material and he hopes to make money with it one day. the violet light shows the purifying process is underway. it involves some pretty advanced a plasma physics. has come on the force if you can think of plasma small both of lightning which carry a strong electric charge that can split molecules in the water and thereby purify the water of those of us on i tunes. the hydrogen produced can be used as a source of energy. it can be mixed with bio gas to create a fuel suitable to power a vehicle. this company van already runs on it the company's test facility can currently purify 200 liters of waste water

a day the facility itself is powered in an environmentally friendly manner with wind and solar energy. comparing before and after the difference is clear there are however still substances in the cleansed water that should be removed the residue at the bottom is made up of minerals that can be filtered out but there are further issues that need to be addressed. what we are looking into is whether we can also eliminate medicines hormones penicillin for example over the next year and a half we'll find out whether or not that's possible. the next step for graph force is to build a larger test facility at the water treatment plant itself could hunkers process be scaled up to treat all the waste water that arrives there. if growth forces technology works at will be a win win situation producing energy and clean water. there's growing interest

against hunkers work in countries around the world including india it could prove to be what we are looking into is whether we can also eliminate medicines hormones penicillin for example over the next year and a half we'll find out whether or not that's possible. the next step for graph force is to build a larger test facility at the water treatment plant itself could honk as process be scaled up to treat all the waste water that arrives there is another concept if ground forces technology works at will be a win win situation producing energy and clean water. there's growing interest to work in countries around the world including india it could prove to be a game changer. let's now get to georgia the country's rural households still depend on what book stores to heat water more and more trees are being cut

down every year in this traditional practice but now an energy cooperated is providing solar powered water heaters to a village in georgia and there's already a noticeable change in the mindset of the religious in favor of the cleaner acknowledges. at 630 a good fetches the hot water like she does every morning. the cows utter has to be cleaned before milking. a little later as well as the family's breakfast she makes cheese and requires a lot of patience she can tell that she's as ready when the consistency is just right. everything here runs like clockwork with no time for breaks.

while there is activity as a housewife i have a lot of work to do i clean make the food clear cows and lots of other things i would have to think there's always something to do their office floor or. none to go to bennett says 60 and was a nurse for 30 years she lives with her husband son daughter in law and grandchildren. who i always need hot water i'm glad we have this system. they received a solar powered water heater from a local energy cooperative. that clothes really had it right on my saved up a bit of money and sold a few things i know it was my husband who really wanted this work never it's quite expensive but it is manageable. like. the cheese is ready not i'm going to abandon is going to take it to the

market. people here bring produce they grow or make at home like vegetables fruit herbs. and cheese. mrs nona has barely unpacked before a trader calms and buys the lot depending on the type of cheese she pays between one euro $50.00 and $2.00 euros 50 per kilo. ysaye they don't get much but if you live frugally you get by we try to get by on it. lisa is also in charge of the housework on her home plus the farm and the grandchildren . she still heats water the traditional way on a wood burning stove in the living room she needs a lot of hot water and therefore a lot of wood. her annual would supply costs between $2240.00

euros in georgia the average income is under 3 and a half 1000 euros a year. we save money so we can afford the wood but sadly there are a lot of families who don't and we doing better than some we can pay for firewood the poor families current. the men collect the wood from high up in the forests of the carcasses mountains. they're still allowed to fill trees here. gogu to here is 27 he comes here regularly. go to estimates that each and every house in his area consumes about $2.00 to $3.00

truckloads of wood every year local to city and. oceans a little something to do if we cut down trees anywhere else we could cause rock slides which are dangerous for the residence so it was a solution. the forest might seem lush but deforestation is rife across georgia the number of trees being cut has to be limited to ensure long term sustainability currently over 12 times that number is being felt. the worker has to mechanics is helping to solve the problem they're cutting solar panels. the machine dates back to world war 2 but it still works there part of the energy cooperative the systems they produce here should help to reduce wood burning and therefore carbon dioxide emissions. the cooperative as provided solar powered water heaters to more than 100 homes in the

village. johnny is a 39 year old teacher and head of the energy cooperative its name means turn on the sun the system is being installed here today. so much of his pleasure residents know about the horseshoe systems so quickly and they know that banks are providing loans for them. to be on guard go to church we don't have to go from go to door people who are interested come to us. none are good about it says back from the markets and the grandchildren are awake her son and daughter in law are at work so she has to look after the children no time for a break at this it's horrible moment i'm 60 years old and i think my life is almost over i do anything to give my children and grandchildren a better future i hope they have a better life. and hot water straight from the tap is

a good place to start. now a group of environmental engineer is doing something fascinating they've been to the window by an outside their bike workshop in one of the largest box in the city capable of generating its own this means they're not connected to the 15th. and 16th when it comes to their daily energy let's look at why they beat it in house killable this practice of sustainable. this bicycle workshop is actually based inside the steel container. recently it was even kitted out with lights. and music keeps the workers in a good mood. the

workshop is located in tempelhof park on the fields of berlin's former airport. most impressively the power is generated by a homemade wind turbine that rises 10 meters above the ground. the turbine can also power small devices like lamps and radios and it stores the power for when there's no wind. the electricity from the turbine comes in here is 3 phase alternating current it's then diverted to the top to the rectifiers that converts the 3 phase alternating current to direct current for the batteries it 1st goes through refused to protect the system then it goes to the batteries here of the batteries connected in series. the turbine was designed by environmental engineers emmanuelle dawn and. the turbine comes as a self-assembly kit it costs around $400.00 euros and most of the components can be found at scrap yards. for

here emanuel is welding on the rear axle of a car which will allow the turbine to rotate in the wind through. what i find fascinating is that you can build this really complex products yourself wind turbines are complex and many processes go into building one today they are also being built on a large industrial scale we have a lot of big megawatt wind turbines here in germany but to build one you don't need a high tech factory all you need is the know how and a few tools take a backstop. the engineers also give workshops to teach people how to build a turbine along with know how it takes concentration and patience. and copper wire is wound into magnetic coils that's how the generator creates electricity. it's just one of the skills the participants learn in the workshop it

takes a week of work to get the system up and running. and maintenance station for the rotor blades has been set up in the basement would often has not holes which makes the blades less aerodynamic so these bumps and holes need to be smoothed out. the conversion of wind power to electricity depends on the right of blades they can be wood rotor blades or the logic proxy resin blades used in industrial wind turbines if they were smooth and perfect then the conversion of wind into electricity is less efficient to. the wind turbine at tempelhof park regular checks this time seem. dorner doing it themselves they're convinced their turbines could be very useful in places that aren't connected feel like turkel grid . in those. if the wind turbine is built properly and has

a decent sized battery bank it could supply energy to a village in a rural area in another country in the. workshop and temple of park has more plans up their sleeves soon the turbine will supply power to an antenna and 3 routers then there will be free wi-fi here all thanks to wind energy. for me it's many small. i hope you enjoy. the many more inspiring stories that will help you make an informed choice. until then.
