  • Power conditioning of an uncontrolled micro-hydroturbine-driven induction generator for distributed generation using a battery energy storage system

    Distributed Generation (DG) and its interconnection to the AC power grid is a relatively new concept. DG employs small generators, which are distributed throughout the power system. The electricity is usually generated by renewable energy sources such as wind, hydro and tidal, which are intermittent in nature. These generators connected to the AC grid may lead to severe power quality problems. ...

  • Building New Industries and Creating New Jobs in a Plan B Economy

    Building a new economy, one that can sustain economic progress, involves phasing out old industries, restructuring existing ones, and creating new ones. This new economy will be powered by renewable sources of energy, will have a more diverse transport system--relying more on rail, buses, and bicycles, and less on cars--and will recycle everything. For example, coal use will be phased out, ...

  • The Developing Role of Permanent Magnets in Renewable Energy

    The developing role of Permanent Magnets in renewable energy production along with the environmental protection is a very worthy topic. An upright permanent magnet should produce a high magnetic field with a near to the ground mass, and should be constant against the inspirations which would demagnetize it. The desirable properties of such magnets are usually indicated in expressions of the ...

  • UE: risk of shortage for 8 rare earth metals

    In a report published on November 4th, the European Joint Research Centre (JRC) has warned of the "risk of shortage" in 2020-2030 of eight strategic metals used in low carbon energy technologies identified in the European SET Plan adopted in 2008. This report continues the work done in a previous study of the JRC from 2011. It is also based on the scenarios presented in 2011 in the roadmap of ...

  • 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 ...


  • A new EE resource: Distributed people

    Energy efficiency is often described as the invisible resource. It improves our energy supply without any of the usual industry trappings: smokestacks, wind turbines, transmission lines and poles. This is one of its virtues.But efficiency’s invisibility also causes problems. Because it operates out of sight – inside walls, underneath lampshades, and in factory motors — efficiency tends to attract ...

  • Green Futures Rely on Strong Magnets

    When lodestone was first discovered before the 1800s people were amazed at this rock that got attracted to itself. They noticed that it pointed to a specific direction every time it was suspended freely or was placed on water. This led to its use in the first compass to give sailors direction as they went for expeditions at sea. Further investigations led to the production of stronger ...

  • Opening the envelope on bearing vibration

    A sophisticated signal processing technique can help to pinpoint bearing failure at an early stage. Chris Hansford, Managing Director at Hansford Sensors, explains. Experienced operators can often tell if a machine is not working properly, on the basis that is does not ‘sound right’. The same principle can be applied – using modern electronics – to identify the exact cause ...

  • Why Rare Earth Recycling is Rare (and What can We Do About it)

    Earbuds, touch screens, CFLs with a warm glow, rechargeable batteries and power windows: Most of us take these things for granted. When we do, we also take for granted a group of elements called rare earth metals, whose special electronic and magnetic properties make them a key component of many 21st century technologies. These 17 elements are actually plentiful enough — you probably have ...

  • SGBI opinion article: shale gas

    Government perceives electric vehicles to be a panacea that will solve problems surrounding air quality and CO2 emissions simultaneously. The EV has two main selling points: reduced CO2 emissions and high efficiency. However, these are only valid at a superficial level and the argument disintegrates under any level of scrutiny. In terms of CO2 emissions, EVs replace ‘average’ cars to ...
