  • Optimal sizing of a hybrid energy system for a semi-arid climate using an evolutionary algorithm

    The use of a genetic algorithm (GA) for optimal sizing of an off-grid hybrid renewable energy system (HRES) is reported. As a pre-feasibility analysis and to determine the appropriate HRES type to be studied, wind energy potential and solar irradiation are first examined for the considered region (Tehran, Iran). These are inputs of the algorithm, and are assessed throughout a year utilising ...

  • Concentrating Solar Power Global Outlook 09 - Why renewable energy is hot

    What is CSP? CSP (Concentrating Solar Power) systems produce heat or electricity using hundreds of mirrors to concentrate the sun’s rays to a temperature typically between 400 and 1000ºC. There are a variety of mirror shapes, sun-tracking methods and ways to provide useful energy, but they all work under the same principle. Individual CSP plants are now typically between 50 and 280MW in size, ...

  • Photocatalytic hydrogen production of the CdS/TiO2-WO3 ternary hybrid under visible light irradiation

    An attractive and effective method for converting solar energy into clean and renewable hydrogen energy is photocatalytic water splitting over semiconductors. The study aimed at utilizing organic sacrificial agents in water, modeled by formic acid, in combination with visible light driven photocatalysts to produce hydrogen with high efficiencies. The photocatalytic hydrogen production of ...

  • Overcoming the dirty secret of clean energy

    A dirty secret of clean energy is that being green can be an expensive pursuit. The cost of solar panels and hybrid cars is declining, but they remain too expensive for many people. As a result, the green energy movement is often viewed as an upper-income trend in the United States.But a recent survey indicates energy efficiency may be a more egalitarian product.The intent of “The 2008 Energy ...

  • Calcium Carbonate, a solution to the energy crisis!

    A 'chemical' solution exists to solve jointly the energy crisis and CO2 release. Thanks to the Lime, “Cycle C4” could produce liquid fuels (petrol, diesel, etc.) with no CO2 release. The cycle presents no technological uncertainty, each step is widely known and controlled. Profitable with a barrel quote at 100 dollars. In 2004, the International Energy Agency annual report predicted that oil ...


  • India’s Potential in Harnessing the Alternate Energy Sources

    Long queues for gasoline, high prices and shortage of gasoline are the signs which show that how natural resources are on the verge of depletion. This shows that it is high time for us to view how to utilize natural resources. India is mainly depended on import of petroleum products for its energy requirements. It meets its requirements by importing 70% of petroleum products. This is a point of ...

  • Legislation Note: Climate Change and Sustainable Energy Act 2006

    The Climate Change and Sustainable Energy Act 2006 is in many ways typical of the hybrid measures taken to link energy and environmental issues. Until very recently, the government’s approach to energy policy was somewhat limited, as illustrated by the 2003 White Paper and mindful of its environmental obligations under the Kyoto Protocol. The 2007 White Paper – Meeting the Energy Challenge – sees ...


  • On energy, we`re finally walking the walk

    The United States has entered a new energy era, ending a century of rising carbon emissions. As the U.S. delegation prepares for the international climate negotiations in Copenhagen in December, it does so from a surprisingly strong position, one based on a dramatic 9 percent drop in U.S. carbon emissions over the past two years and the promise of further huge reductions. Prominent among these ...


  • Plan B efficiency and conservation measures drop energy demand by 2020

    Projections from the International Energy Agency show global energy demand growing by close to 30 percent by 2020, setting the stage for massive growth in the carbon dioxide emissions that are warming our planet. But dramatically ramping up energy efficiency would allow the world to not only avoid growth in energy demand but actually reduce global demand to below 2006 levels by 2020. We can ...
