  • International energy technology collaboration: wind power integration into electricity systems

    A rapid growth of wind power since the 1990s has led to notable market shares in some electricity markets. This growth is concentrated in a few countries with effective Research, Development and Demonstration (RD&D) programmes and with policies that support its diffusion into the market place. The speed and depth of its penetration in these electricity markets have amplified the need to address ...

  • Wind energy today and in the 21st century

    Wind energy is the most promising of the new renewable sources of energy. By the end of 1998, the global installed capacity of modern grid connected wind turbines was some 10,000 MW, and the growth rates of installations worldwide are 30%-40% annually. The cost of wind energy was reduced by 30% between 1991 and 1997 and the cost reduction is foreseen to continue. This article reviews the reasons ...

  • Geothermal Energy Technologies

    Technology Overview   Nowhere is the raw power of geothermal resources more evident than at the Old Faithful geyser at Yellowstone National Park. (Joel Renner)  Geothermal energy is natural heat from the Earth's interior where temperatures reach greater than 7000°F. The heat is brought to the surface as steam or hot water—created when water flows through heated, permeable ...


  • Research and development in ocean energy technologies

    The volatile fuel prices for electricity generation, elevated concerns about global warming and energy security has prompted countries to look for alternative energy sources. One of the alternative energy sources is ocean energy. Currently, there is few ocean energy technologies that are commercially available to harness electrical energy from ocean despite the fact that ocean covers more than ...

  • Wind energy in Italy: regulatory and technical aspects

    Italy has carried out the deregulation of the electricity sector. The EU 'Renewable Directive' gave Italy a very ambitious burden sharing: by 2010, 25% of the demand will be faced by renewable energy against a 1997 baseline of 16%. To sustain such development, the producers/importers have a yearly obligation to inject into the system 'green production': in 2002 by 2% increasing to 3.05% by 2006 ...

  • Prospect of offshore wind energy development in Japan

    In Japan, the cumulative capacity of wind turbine generation systems on land has increased steadily in recent years. To install a large number of wind turbines has inherent problems such as shortage of suitable land, and inadequate infrastructure such as power cables and roads. The necessity for development of offshore wind turbine generation systems has been recognised based on the above ...

  • Occupational safety and health in the wind energy sector

    As the European Union power sector continues its move away from oil, coal and nuclear fuels,wind energy has experienced tremendous growth over the past decade and this is expected to continue. The wind energy sector is relatively young with turbine technology constantly progressing and this creates an ongoing responsibility to ensure workers that conduct tasks such as installations, ...

  • Aiming High Rewarding Ambition in Wind Energy - Report

    EXECUTIVE SUMMARY With 392 GW installed, wind energy can be the single largest source of power generation in the EU by 2030 ahead of coal and gas. Wind energy already plays a significant role in the European power sector. In 2014, the wind industry installed 11,791 MW in the EU - more than gas and coal combined. Today wind energy can meet 10.2% of Europe’s electricity demand ...

  • Integration of pump storage hydro with wind energy

    Renewable energy has significant advantages as it does not contribute to Greenhouse Gases (GHG). Wind energy is a renewable energy alternative that is being installed worldwide. However, wind energy is unpredictable and thus, unavailable as compared to conventional generation. The availability of wind energy compared to conventional power plants is a cause of contention. Currently, the rate of ...

  • Sources of experience – theoretical considerations and empirical observations from Danish wind energy technology

    This paper attempts to establish better understanding of processes within the black box of industrial learning. Through theoretical considerations and empirical observations, this paper also aims at finding the truest and fairest expression of an experience curve diagram. The paper concludes that experience curves based on the cost of produced electricity are more true and fair than those based ...
