  • 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.' ...

  • Rational use and management of geothermal energy resources

    This article identifies and explains several attributes of geothermal energy. High exergetic efficiency due to a close temperature tie between geothermal energy and district heating and cooling was noted. Parameters governing the rational use and management of geothermal energy systems with special emphasis on integrated-cascaded district energy systems were formulated and explained with two case ...

  • 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 ...

  • Lessons from Indonesia: Mobilizing Investment in Geothermal Energy

    Developing countries will need about $531 billion of additional investments in clean energy technologies every year in order to limit global temperature rise to 2°C above pre-industrial levels, thus preventing climate change’s worst impacts. To attract investments on the scale required, developing country governments, with ...

  • H2S Emissions Control at Geothermal Plants

    The LO-CAT® II process is used to control H2S emissions and reduce odors at geothermal power plants. Geothermal steam, considered to be a clean and environmentally friendly source of energy, is produced when water seeps into high temperature, high pressure formations below the earth's surface. The steam is brought to the surface through production wells and then expanded through a turbine to ...

  • Oceans of Energy

    Technologies that harness the energy of moving water or temperature differentials in the oceans promise to deliver abundant carbon-free electricity. Long before humans got hooked on fossil fuels, we learned how to harness the power of water to do work. Rivers ran mills that ground flour, sawed logs or spun looms that transformed fibers into textiles. Later generations realized that moving water ...

  • Renewable Energy - A Key Solution to End Global Warming

    Scientists have spent years trying to find the causes of global warming leading to significant changes in the world’s climate. Their research shows that several factors have contributed to the rise of earth’s temperature and altering of natural cycles and actions. One key reason is excessive emission of greenhouse gases like, methane and carbon dioxide (CO2) in the atmosphere. These ...

  • Mobilizing Climate Investment: The role of international climate finance in creating scaled-up, low-carbon energy

    Between now and 2050, developing countries need an estimated $531 billion per year of additional investment in energy supply and demand technologies in order to limit global temperature rise to 2° C above pre-industrial levels. To achieve this scale of investment, developing country governments and custodians of international public finance will need to deploy limited public finance in ways ...

  • Comparison of exergetic performance of HFC based single and half effect absorption cooling systems
