Who coming to you from mumbai in india all of them exporting that its lets look at how calm was the best bengal saying no to be so i would German Company has found a devolution living we clean waste water and how young engineers in bahrain are creating their own wind turbine 1st lets head to the east or for india in west bengal traditional farmers here like many of the agents around the country use diesel pumps to water their fields these are expensive and very polluted one company is helping them make the switch to clean energy on a jeep is still sticking out solar water pumps in farms and even enabling the farm was water on the promos. Of the. Only. Shes the 1st woman to install a solar farm in this willetts. 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 new plan to install a drip irrigation system nor water usage then well be able to grow flowers fruit and other vegetables. The villages 225 kilometers north of west bengals capital kolkata these are good days for the farmers here but a visit here during the last monsoons would have painted a bleak picture frequent power cuts and the serious cassady of water had done most of these fields into dry wasteland spelling doom for the farmers. Todays lush green harvest reveals a new Development Sees esky saline who deals in Farm Equipment in the region. Ill be working with the farmers and farming equipment and i would visit each of the homes and devices subsidised by the government some form of storage meaning there were facing a water crisis and they complained about not getting enough electricity they asked me about solar energy in whether they could use it to pump water they said if they could utilize that for farming it for improve their lives or the body. Is the 1st religion the area to have made the switch from diesel to solar power but its a geisha need a transition that has proved to be a boon for its farmers. From being able to grow only paddy rice once a year farmers like superman 2 they practiced multi cropping all year round. Going on where theyre going to only there were no arrangements for water here used to from using pumps. Generators there were about the. Or harvest was much in it wasnt good enough. Selling proofs in solar pumps for in storage when i was here when they were 3 must. Have been able to grow them all in good quantities in the past farming cost us a lot more used to spend about 40000 rupees on design of the car just the. Very was 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 put its no one as the joint Liability Group under which several farmers invest collectively in a bomb the scheme is the brainchild of calls out of this Company Owner g. E. Solar. Folks who would. Be investment because something make us all very good in bombay requires a lot of investment and are so basically what we did was we understood what degree b. s work and we tried to could be enjoying globality groups awaiting the liability doesnt forward to one farmer it is basically an entire herd they fight with the farmers they come together and then they pay for the entire system and that is how shared expenses can bring the cost down. Owner 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 Region Support on energy 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 thats what was our objective to ensure that how farmers are able to repay the bank loans one through the savings in the diesel that theyre not using and secondly by a big increase in their additional income as theyre able to do multiple cropping. At a price of a around 5000 euros a solar power 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 coffee with water scarcity to improve their livelihoods. Renewable sources of energy like solar by the very famous are sustainable but how realistic is the goal to completely switch to this form of Power Generation next explain the oath you want so that question. Carbon rich and cheaply priced fossil fuels continue to dominate our Global Energy supply. 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 quote renewables account for just 10 percent. Of. 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 theyre not always reliable. Photovoltaic system is sealed on average about 20 watts per square meter when the sun is up. At night its a different matter. A fossil fuel burning power plant generates 100. 00 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 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 y. 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. Possible. Now we see what can be a source of the new bill energy a company in germany has come up with a method to not only clean beast water so that it can be of use but also to generate Hydrogen Hydrogen is a 0 emission fuel and can be used to power up automobiles feasible is this lets fight that. 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 citys 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. With therefore we release the treated waste water we add a lot of oxygen to make sure theres enough in our lakes and rivers for the fish and other life forms. As you can see it creates foam but only briefly its 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 whats left over is sewage sludge. Its then fed into bio gas digesters. The gas thats produced their powers turbines to generate a. Tricity to run the Treatment Plant. Whats 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 the 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. Thats where yens 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 plasma physics. In this plasma coming come on the 4th 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 damage 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 companys 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 so i think over the next year and a half well find out whether or not thats possible. The next step for graph force is to build a larger Test Facility at the water Treatment Plant itself could harm because process be scaled up to treat all the waste water that arrives there is another concept if Ground ForcesTechnology Works at will be a win win situation producing energy and clean water. That is growing interesting because work in countries around the world including india it could prove to be a game changer. Lets now get to georgia the countrys rural households still depend on what book stores to heat water more and more trees are being cut dollars every year in this traditional practice but now an energy cooperated is providing solar powered water heaters to a village in georgia and theres already a multiple change in the mindset of the religious in favor of the cleaner technologies. At 6 30 am. 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 familys breakfast she makes cheese and requires a lot of patience she can tell the cheese is ready when the consistency is just right. Everything here runs like clockwork with no time for breaks. While theyre effective because i housewife i have a lot of work to do and i clean make the food make clear cows and lots of other things so if the sack theres always something to do their office will order. None or go to bend it 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 im glad we have this system. They received a solar powered water heater from a local Energy Cooperative. That clothes read it right on my saved up a bit of money and sold a few things but it was my husband who really wanted this work never its quite expensive but it is manageable. Like. The cheeses ready not on 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 nonny has barely unpacked before a trader calms and buys the lot depending on the type of cheese she pays between one euro 50 and 2 euros 50 a kilo. A say that you dont get much but if you live frugally you get by we try to get by on it yet. These are packing love 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. The club would come form of we save money so we can afford the wood but sadly there are a lot of families who dont manage what were 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. Theyre 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. Alone to sit in a room which are all shuttle which will do. If we cut down trees anywhere else we could cause rock slides which are dangerous for the residents so what if you know. 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 workers to mechanics is helping to solve the problem theyre 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 that his pleasure to its know about the horses systems so quickly and they know that banks are providing loans for them. To be out in cockroaches that you dont have to go from door to door people who are interested come to us. Not to go to heaven 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 its horrible moment im 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 engineers in bali is doing something fascinating theyve been to the window by an outside their bike workshop in one of the largest box in the city full of generally think its all about what this means theyre not connected to the 15th. And 16th when it comes to their daily energy lets 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 carried out with lights. And music keeps the workers and. The workshop is located in temple park on the fields of berlins 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 theres no wind. The electricity from the turbine comes in here is 3 phase alternating current its 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 a fuse to protect the system then it goes to the batteries here are the batteries connected in series. The turbine was designed by environmental engineers don and. The turbine comes as a selfassembly kit it costs around 400. 00 euros and most of the components can be found at scrap yards. Full. Here emanuel is welding on the rear axle of a car which will allow the turbine to rotate in the wind through. Your 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 dont need a high tech factory all you need is the know how and a few tools take a back stop. The engineers also give workshops to teach people how to build the turbines along with know how it takes concentration and patience. And copper wire is wound into magnetic coils thats how the generator creates electricity. Its 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. For 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. Doing it themselves theyre convinced their turbines could be very useful in places that arent connected feel like turkel grid. 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 wifi here all thanks to wind energy. For me its many small. I hope you enjoy. Many more Inspiring Stories making informed choice. And building the. The food is good. Good good. Good. Good. Good. Loneliness is more than just being alone. Loneliness makes you sick and its affecting more and more people. Researchers are investigating the causes and developing strategies that can help combat this problem. Against the lowliness epidemic.
