  • Sustainable improvement of drinking water quality by nanofiltration powered by renewable energy

    Desalination membrane technology is increasingly used for water production. However, the main disadvantage of desalination is related to energy consumption and CO2 emissions, so desalination powered by renewable energy (RE) is getting interest. In this study nanofiltration (NF) membranes have been used for drinking water quality improvement in a pilot plant (50 m3/day) powered by RE ...

  • Create new jobs & cut emissions by investing in renewable energy efficiency

    At a time when major US companies are announcing job layoffs almost daily, the renewable energy industry is hiring new workers every day to build wind farms, install rooftop solar arrays, and build solar thermal and geothermal power plants. The output of industrial firms that manufacture the equipment for these energy facilities is expanding by well over 30 percent a year. These investments both ...

  • 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 ...

  • 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, ...

  • 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 novel stabilisation scheme for hybrid photovoltaic, fuel–cell and diesel gen–set utilisation system

    The paper presents a novel FACTS–based modulated filter compensator scheme for a hybrid renewable photovoltaic–diesel–fuel cell common DC bus interface scheme. The proposed standalone photovoltaic–diesel–fuel system is fully interfaced using the common AC–DC collection bus topology. This allows for full decoupling of AC and DC type green source and ensures full flexibility in controlling the ...

  • Energy Security

    Renewable & Clean Energy Solutions to Secure Energy Independence from Foreign Oil. FOREIGN OIL: As imports grow and world prices rise, the amount of money we send to foreign nations every year is soaring. At current oil prices, we will send $700 billion dollars out of the country this year alone — that’s four times the annual cost of the ...

  • The Energy Revolution is Here

    We live in an exciting time. Yes, glaciers are melting, sea levels are rising, and in my new home in the Western United States, earlier snowmelts, longer summers, and hotter temperatures have made wildfires 400 percent more frequent. And yet, there are encouraging signs we are in the midst of an energy revolution that is sure to transform our climate, our economy, and our lives for the better. ...
