  • The Smart Grid ‘Acid Test’ – Accommodating Variable Renewable Energy (VRE)

    In the previous posts, we have discussed the need for the regulators and policy makers to develop a new framework on which to build Smart Grid. The next stage is to investigate how much VRE can be accommodated through Smart Grid. Maximising the amount of VRE that can be accommodated is the ‘Acid Test’ for Smart Grid. We are moving from a central system that provides consistent power ...

  • A case study of hybrid wind–solar power system for reduction of CO2 emissions

    In this study, the solar radiation and wind data pertaining to Bigadic region are analyzed to assess the performance of a hybrid Photovoltaic–Wind–Diesel–Battery energy system. The average energy consumption of the system is about 20.33 kWh per day and 600 kWh per month, with a peak power demand of 2.4 kW. A 10 kW Wind Turbine and a 1 kWp PV energy system with 48 kW battery are installed. The ...

  • 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, ...

  • Size optimisation of hybrid wind-PV power generation systems for remote rural areas

    Electrical power generation with renewable energies, such as wind and solar, plays an important role in the electrification of remote rural areas. Since there are always seasonal and synoptic variations in wind and solar resources, a hybrid system, consisting of both wind and solar energy, may be more reliable and economical than a single energy system: this is because either energy can ...

  • 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.
