  • The Aberdeen Heat and Power district energy schemes - Case Study

    District energy schemes seemed to be the right decision for the Aberdeen City Council (ACC). They had conducted a study of its housing stock and established that the multi-storey buildings (of which they have 59 in Aberdeen) were too expensive to heat. These buildings also had lower energy ratings, thus people living in them were subject to high energy bills. In 2002, as one of the results of the ...

  • Much light, little heat efficiency

    Energy efficiency in the US is much light and little heat – literally.  Government policy pays a great deal of attention to saving electricity, but focuses little on the thermal energy we waste.  “Policy is electricity-centric in the US. Unless you are making kilowatts, the most efficient investments are off the radar,” said Rob Thornton, president of the ...

  • Combined Heat and Power – Questions and Answers

     1. What are the benefits of CHP for business?   combined heat and power (CHP) is a well-proven technology, recognised worldwide as a cleaner alternative to traditional centralised generation. Its long-term future in the global energy markets is secured by CHP's ability to provide a multitude of financial, ...

  • Utilisation of deep geothermal energy for heating purposes

    The Hot-Dry-Rock-(HDR) technology allows a location-independent utilisation of geothermal heat, because aquifers in deep formations, i.e. layers filled with water, are not necessary. The flow paths for the circulating water in a depth of 4 km are created by hydraulic fracturing of existing gaps. Due to the fact that this new technology is quite cost-intensive, high annual load duration of the ...

  • Advanced plants to meet rising expectations for nuclear power

    Nuclear power produces 15.2% of the world's electricity. Many countries are planning to either introduce nuclear energy or expand their nuclear generation capacity. Design organisations are incorporating both proven means and new approaches for reducing the capital costs of their advanced designs. In the near term, most new nuclear plants will be evolutionary design, often pursuing economies of ...

  • Geothermal Energy... Power from the Depths

    The Earth's crust is a bountiful source of energy—and fossil fuels are only part of the story. Heat or thermal energy is by far the more abundant resource. To put it in perspective, the thermal energy in the uppermost six miles of the Earth's crust amounts to 50,000 times the energy of all oil and gas resources in the world! The word 'geothermal' literally means 'Earth' plus 'heat.' ...

  • Solutions for the exploitation of biomass energy in mountain regions

    Using tow-cables to extract and transport biomass to forest paths Many forests are located on mountainous terrain with steep slopes, making their exploitation not economically viable, at least with traditional methods. This can lead to the abandonment of such hilly woodlands, giving rise to rodent infestation or forest fires, with resulting damage to the woods themselves and to surrounding areas. ...

  • Making environmentally friendly fuel from wood chips - Case Study

    The RUF briquetting press earns the Ortinger company additional profits During the production of round bars or rods for flags, skewers and many more products made from wooden planks, lots of wood chips are accumulated. Instead of disposing of them as waste, the wood processor Ortinger presses them into briquettes, which they then sell as fuel. This way they can economically support ...

  • Energy efficiency: Big deals and new ideas

    The economic premise behind energy efficiency –  that it’s cheaper to save a unit of energy than to make one – has caught on in the US.  Energy efficiency spending is up, and our energy use is declining, measured both per capita and per dollar of gross domestic product, according to government ...

  • The Emerging Power of Microgrids

    Over many decades, the centralized power grid — a one-way flow of electricity, generated by large, remote power plants and distributed over miles of transmission lines to homes and businesses — succeeded in delivering electricity across continents to billions.
