Yet to the four corners of the planet, in corners sometimes lack infrastructure, NGOs, small and (very) large contractors generate electricity in sometimes surprising ways. And if we take example on them,.? Dale Vince left school at age 15. Young adult and now activist environmentalist, he went on the road in a truck whose roof is equipped with a small wind turbine. A windy day, he clicks and decides to go into debt to build its first wind. Today, this hippie Lord is the head of a green empire that weighs hundreds of thousands of pounds sterling and creates 20 new jobs every month, said the Guardian newspaper. This vegetarian and capricious boss has installed his company in Gloucestershire, where everything began. Today, he continually reinvests profits in new wind and solar buildings. Not completely philanthropist provided, environmentalist did its entry in the list of the richest people established each year by the Sunday Times. My success proves that renewable energy economy is credible, keeps it to repeat today that his company sells from 100% kilowatts of the force of the wind and the Sun. His goal in term? Provide with electricity rates the lowest in England. It has already ceased to be the most expensive. At just 21 years, Thato Kgatlhanye comes, she won second prize in the competition of young African entrepreneurs, with an supportive idea that reports the South African site The Daily Vox: binders made of recycled plastic and equipped with a small solar panel. Intended for children in rural areas of South Africa, Repurpose Schoolbag recharges on the school trip and on the threshold of the class during school hours. When night falls, the accumulated energy allows to study or simply to inform the family. Thanks to its price and NGOs who buy his binders, the young leader of business uses of addition today eight full time staff. Juan Rodriguez is also at the head of a social enterprise. Located at the other end of the globe, it provides small units of solar electricity in the remotest corners of the Guatemala, families not connected to the electrical network. Particularity of its units? Sponsored by businesses, says Forbes magazine, they are installed free of charge by the mark. In return, their name is engraved on it. Households have more than to pay – renewable – energy they consume. A substantial gain for families who spent a fortune in candles or kerosene to power generators. A positive development both for the families who see lower their energy costs from the first day for the planet and for the CEO who bills electricity and provides for an increase of its turnover by 1700% with the distribution of 100,000 kits in the next five years. These are small streams that are large rivers. Practical Action, undertaken both social and association, understood. For several years, tells The Guardian, it installs in areas – devoid of electricity but equipped with stream – hydroelectric Central mini ecological. Its purpose is to bring electricity (at low cost) where before the kerosene was legion. And in large enough quantities to villages affected by rural exodus can develop refrigerators, medical equipment, light; or even to install small businesses to revitalize streets and combat poverty, as shown in this video, filmed in the Peru: more close to home, eliminating the excesses of the night before while recharging his laptop, it is now possible. You may have noticed these machines pedal funny that bloom in stations and airports: bikes with free access for travellers who may charge their phone to the strength of the calf. A practical initiative which seem to have conquered these travellers from the airport of Schiphol in Amsterdam. Andy Welkin and Steeve Blood, two young Americans, have decided to go further. Why not pedal to rotate his office computer (and take the opportunity to combat the sedentary lifestyle)? It was assumed that the human body is capable of producing 75 watts in two hours, they have developed into machines that allow to load her laptop in 30 minutes but also supply a computer, a mixer, a coffee mill or more bulbs. To realize their project, the two patterns of Pedal Power appealed to a participatory fundraising campaign that allowed them to launch Internet sales. Their invention is still expensive (a little more), because it is built by hand, but Andy and Steeve hope quickly to lower costs in industrializing their production. In the Ghanaian countryside are sometimes children who produce electricity,. in having fun. Mission to Africa, an engineer for an oil company notices that most of the villages and schools do not have electricity and the smaller games. After leaving the company, he embarks on the development of a turnstile with a turbine that produces electricity. Since 2006, they are installed everywhere near the classrooms in the country. The energy produced is used to charge lanterns that students report at home at night. Around Nairobi, the capital of the Kenya, small buildings generate electricity in a surprising way: by recycling the excrement produced by the inhabitants of the slums. The very serious British newspaper The Guardian tells the story of one of these bio-centres, that of Kibera, the largest slum in the capital. The building, located outside the district, is equipped with toilets and showers. It is managed by Umande association which has decided to transform some 720 tons of smelly rubbish, produced each day by the 2.4 millions of slum dwellers, in energy asset. Once collected in one of 57 ‘bio-centres’ of Nairobi, feces stay in a composter that harvesting the methane. It will be then converted into energy used for powering the slum. In partnership with large cities like Washington or Sacramento, the startup Alex Laskey and Daniel Yates compares a city homes electricity bills. Area and equal equipment, if a family spends more than its neighbors, it will receive their bills to realize that it can also make energy savings and therefore money. These poor students also receive advice, and can download an application that will show them in real time their consumption peaks, or be recalled to order by SMS in case of overconsumption. The company then instructs the city where implement targeted information campaigns. Intrusive? Of course. But effective: the cities having had recourse to their services found an average decrease of consumption of electricity by about 6%. . For more about this subject read reference.
