Some of that who coming to you from mumbai in india over the next 30 minutes lets look at how calm was the best bengal are saying move to be so i would German Company has found the devil usually we mean we see what happens and how young engineers in berlin are creating their own wind turbine 1st lets 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 pretty one company is helping them make the switch to energy on a jeep is still sitting out solar water pumps in farms and even enabling the farmers water on the pros. Lulu. Shes 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 well be able to grow flowers fruit and other vegetables. The villages 225 kilometers north of west bengals capital. 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 subsidized by the government some farmer story i mean 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 they said if they could utilize it for farming it would improve their life. The body. Is the 1st willage in the area to have made the switch from diesel to solar power what is it a geisha me 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 to be practiced multi cropping all year round. Only there were no arrangements for water here used to from using pumps. Generators were about the. Or harvest 1st martin it wasnt good enough. Selling proofs in solar plants for in storage when i was here when they were through there must. Have been able to grow them all in good quantities in the past farming cost us a lot more you suspended 40000 rupees on design of the car just the. Truth where you are when the need arises farmers like margy now also have the option to buy water from local entrepreneurs like open up or. There is also another Business Model that has been successful and would you put its known as the joint Liability Group under which several farmers invest collectively in a pump the scheme is the brainchild of calls out of Business Company owner g. E. Solar. Who would. Be investment because something that was already getting a lot of investment and this is so basically what we did was we understood what the only dignities worth and we tried to could be enjoying globally the groups awaiting the liability doesnt fall to one farmer it is basically an entire day 5 or 6 farmers they come together and then they pay for the entire system and that is how shared expenses can bring the cost down. On energy was founded in 2009 as a spinoff of the enjoy your switch on which works to promote environmental ed walker sea 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 energy has installed over 250 s. Solar microgrid and sold over 800 solar irrigation farms across india are getting banks buy in so that they can start lending for solo pumps was very critical it was a very important quest abolition of your pay back 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 their diesel that theyre not using and secondly by a big increase in their additional income as theyre 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. 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 Irrigation Systems have helped farmers in other villages to move agricultural productivity and cope with what is cassadee 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 oaths 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 while 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 powerplant 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. In. Some countries however are in the process of switching to 100 Percent Renewables custer rica 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 isp. 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 used but also to generate Hydrogen Hydrogen is a 0 emission fuel and can be used to power up. Feasible lets fight. 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. Before 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 to 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 electricity 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 why again 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. Violet light shows the purifying process is underway. It involves some pretty advanced a plasma physics. In this plasma coming 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. From. 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 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 hunkers process be scaled up to treat all the waste water that arrives there has enough plants that if Ground Forces Technology Works at will be a win win situation producing energy and clean water. Theres growing interest to his work in countries around the world including india it could prove to be a game changer. Lets now head to georgia the countrys 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 cooperate it 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 that she is ready when the consistency is just right. Everything here runs like clock work with no time for breaks. Well respected as a housewife i have a lot of work to do i clean make the food clear cows and lots of other things so if the fact theres always something to do their office floor or. None are good ive been it size 16 and was a nurse for 30 years she lives with her husband son daughter in law and grandchildren. That come out 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 ready for you know 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 it is manageable. Like. The cheese is ready not and 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. Ysaye really dont get no but if you live frugally you get by we try to get by on it yeah. 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 dont and im sure you know 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 one clue to sit in a room which will shuttle was something to do if we cut down trees anywhere else we could cause rock slides which are dangerous for the residents so what if you know sort of. 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 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 his pleasure residents know about the horses systems and they know that banks are providing loans for them and. We dont have to go from door to door people who are interested come to us. 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 this is horrible 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. Hand hot water straight from the tap is a good place to start. Now a group of environmental engineers it is doing something fascinating theyve been to the window by an outside bike workshop in one of the largest box in the city of general do you think. This means theyre not connected to the City Electric grid and. When it comes to their daily energy lets look at why they built it in house this is. 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 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. Just one from. 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 emmanuelle gone and. The turbine comes a selfassembly 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 theyre 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. The engineers also give workshops to teach people how to build the turbines along with know how it takes concentration and patience. And 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. Or the conversion of wind power to electricity depends on the right of blades they can be wood roto blades or the large a proxy resin blades used in industrial Wind Turbines if that were smooth and perfect then the conversion of wind into electricity is less efficient due. To. The wind turbine at tempelhof park regular checks this time see manual dorner doing it themselves theyre convinced theyre turbines could be very useful in places that arent connected to the electrical grid. When theres been gotten out to you 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 and on the on the bike 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.
