... that the first recorded instance of solar distillation was by 16th century Arab alchemists? A large-scale solar distillation project was first constructed in 1872 in Chile a mining town of Las Salinas. The plant, which had a solar collection area of 4,700 m², could produce up to 22,700 L per day and operated for 40 years. Individual still designs include single-slope, double-slope (or greenhouse type), vertical, conical, inverted absorber, multi-wick, and multiple effect. These stills can operate in passive, active, or hybrid modes. Double-slope stills are the most economical for decentralized domestic purposes, while active multiple effect units are more suitable for large-scale applications.
... that the International Renewable Energy Agency (IRENA) to promote widespread and increased adoption and sustainable use of all forms or renewable energy was founded in 2009 ? Acting as the global voice for renewable energies, IRENA will facilitate access to all relevant renewable energy information.
IRENA's founding reflects a growing consensus among governments around the world on the need to speed up the commercialization of renewable energy worldwide. IRENA provides advice and support to governments on renewable energy policy, capacity building, and technology transfer. IRENA will also co-ordinate with existing renewable energy organizations, such as REN21.
... that because solar cookers use no fuel and they cost nothing to run, humanitarian organizations are promoting their use worldwide to help slow deforestation and desertification, caused by using wood as fuel for cooking ? Solar Cookers are a form of outdoor cooking and are often used in situations where minimal fuel consumption is important, or the danger of accidental fires is high.
... that The Clean Tech Revolution: The Next Big Growth and Investment Opportunity, the 2007 book by Ron Pernick and Clint Wilder, argues that commercializing clean technologies is a profitable enterprise that is moving steadily into mainstream business ? As the world economy faces challenges from energy price spikes, resource shortages, global environmental problems, and security threats, clean technologies are seen to be the next engine of economic growth.
Pernick and Wilder highlight eight major clean technology sectors: solar power, wind power, biofuels, green buildings, personal transportation, the smart grid, mobile applications (such as portable fuel cells), and water filtration. Very large corporations such as GE, Toyota and Sharp, and investment firms such as Goldman Sachs are making multi-billion dollar investments in clean technology.
... that REN21, the Renewable Energy Policy Network for the 21st Century, is a policy network that provides a forum for international leadership in renewable energy policy, in order to share knowledge and facilitate the rapid growth of renewable energy technologies in developing countries and industrialised economies ?
The network launched in June 2005, operates from offices in Paris, France, and is provided by the United Nations Environment Programme and the Deutsche Gesellschaft für Technische Zusammenarbeit (German Technical Cooperation), in collaboration with the International Energy Agency. Since 2005 REN21 has produced an annual Renewables Global Status Report, with Eric Martinot and Janet Sawin as lead authors.
... that the United Nations Intergovernmental Panel on Climate Change (IPCC) published Renewable Energy Sources and Climate Change Mitigation (SRREN) in May 2011 ? The IPCC examined renewable energy and energy efficiency in its fourth assessment report, published in 2007, but members have now decided that renewable energy commercialization merits in-depth coverage because of its importance in reducing carbon emissions.
... that efficient energy use is most often achieved by adopting a more efficient technology or production process ? Energy efficient buildings, industrial processes and transportation could reduce the world's energy needs in 2050 by one third, and help controlling global emissions of greenhouse gases, according to the International Energy Agency. Energy efficiency and renewable energy are said to be the twin pillars of sustainable energy policy.
... that the Exelon Pavilions, a set of four solar energy generating structures in Millennium Park of Chicago, provide sufficient energy to power the equivalent of 14 star-rated energy-efficient houses in Chicago ? In addition to producing energy, three of the four pavilions provide access to the park's below ground parking garages and the fourth serves as the park's welcoming center. Exelon, a company that generates the electricity transmitted by its subsidiary Commonwealth Edison, donated approximately $5–6 million for the Pavilions.
... that Selling Solar: The Diffusion of Renewable Energy in Emerging Markets, a 2009 Earthscan book by Damian Miller, argues that in order to solve the climate crisis, the world must immediately and dramatically accelerate the commercialization of renewable energy technology ? This needs to happen in the industrialized world, as well as in the emerging markets of the developing world where most future GHG emissions will occur.
... that the Ontario Sustainable Energy Association (OSEA) is a non-profit organization supporting the growth of renewable energy and Community Power projects in the Canadian Province of Ontario? OSEA advocated an advanced renewable energy Feed-in Tariff program for Ontario, resulting in the creation of the Renewable Energy Standard Offer Program, a precursor to the Green Energy Act and, in 2007, the most progressive energy policy in North America in a decade. OSEA has approximately 130 community and industry members as well as individual members.
... that the Cragside country house in Northumberland, England was the first house in the world to be lit using hydroelectric power? In 1870, water from one of the estate's lakes was used to drive a Siemens dynamo in what was the world's first hydroelectric power station. The resultant electricity was used to power an arc lamp installed in the Gallery in 1878.
