  • Simultaneous optimization of clustering and fuzzy IF-THEN rules parameters by the genetic algorithm in fuzzy inference system-based wave predictor models

    Prediction of wave parameters is of great importance in the design of marine structures. In this paper, two shortcomings with the adaptive network-based fuzzy inference system (ANFIS) model for prediction of wave parameters are remedied by employing a genetic algorithm (GA). The first shortcoming in the ANFIS model goes back to its problem for automatic extraction of fuzzy IF-THEN rules and ...

  • WorldWaves wave energy resource assessments from the deep ocean to the coast

    Abstract WorldWaves is a global wave and wind climate package developed through EU and industry sponsorship over many years. The offshore data incorporates global hindcast and operational wave and wind data from ECMWF, validated and calibrated with independent satellite and buoy data worldwide. These data, which may comprise full directional wave spectra time series, are used as ...

  • Environmental impacts of ocean-energy systems: a life-cycle assessment

    Ocean-energy technologies — which harvest renewable energy from the sea — will have a significant role to play in a future low-carbon society. A recent life-cycle analysis of different ocean-energy devices has found that life-cycle environmental impacts are caused mainly by the materials used in the mooring, foundations and structures. Improving the efficiency and lifespan of the ...

  • Modelling runoff on ceramic tile roofs using the kinematic wave equations

    Generally, roofs are the best candidates for rainwater harvesting. In this context, the correct evaluation of the quantity and quality of runoff from roofs is essential to effectively design rainwater harvesting systems. This study aims to evaluate the performance of a kinematic wave based numerical model in simulating runoff on sloping roofs, by comparing the numerical results with the ones ...

  • EC support for UK power link raises Ireland’s offshore export potential

    The European Commission (EC) announced November 18 it had given priority status to ISLES, a cluster of Irish Sea grid projects which would transmit power from proposed Irish offshore wind farms to the UK grid. There are currently five Irish offshore windfarm projects for a total 2.6 GW of capacity. The inclusion of ISLES in the EC’s list of “projects of common interest” allows ...

  • European Power Markets in Transition

    With European energy markets in transition, all market participants now face a number of potentially tricky challenges. A combination of EU initiatives, increasingly invasive regulations and a backdrop of falling and less volatile commodity prices, have precipitated an era of change and uncertainty in which there are fewer trading opportunities and profits are harder to come by. Analysis ...

  • Renewable energy progress report

    What is the Renewable energy progress report and what is its purpose? The Renewable Energy Directive states that a progress report should be issued every two years. The purpose of this progress report is to assess Member States' progress in the promotion and use of renewable energy in line with the 2020 targets. In addition, it contains sections on ...

  • 2014 JRC Ocean Energy Status Report

    Abstract Oceans and seas have the potential to play a significant role in providing clean energy. Different technologies are currently being developed to ensure a long term contribution of ocean energy to the future energy system. Among the different ocean energy technologies, tidal and wave conversion systems are expected to contribute the most to the European energy system in the short ...

  • Study on hydrodynamics and heat transfer of solitary wave on film flow with CFD method

    In this paper, a capacitance probe and high speed camera are adopted to study the solitary wave of falling film on large flat plate experimentally. Two types of solitary wave are studied with a Computational Fluid Dynamic (CFD) method based on the measuring data. The water–air shear stress on the interface of the solitary wave is modelled in the numerical calculation. The results indicate that ...

  • Earthy, solaris and atmospheric energy sources

    Earth, sun and atmosphere are the ultimate energy resources. In addition to fossil fuels, earth radiates over 45 TW geothermal energy. Sun radiates about 89 PW energy to earth's surface. Lunar gravity supplies over 100 GW tidal ocean energy. Accessible energy from geothermal, solar, tides, waves and winds is far more than our current 17 TW energy demand, yet there are new avenues like tornadoes ...

  • “We continue to be stunned at how rapidly the ocean is warming.”

    Oceans have been absorbing more of global warming’s heat and energy than would normally be expected, helping to slow rates of warming on land. But how long will that last? Probing a blue abyss can be an abysmal recipe for the blues. For every 10 joules of energy that our greenhouse gas pollution traps here on Earth, about 9 of them end up in an ocean. ...

  • National Grid Alert Triggers Wave of Enquiries for Renewables Sector

    UrbanWind today reported a sharp increase in companies enquiring about on-site power generation, following National Grid’s warning yesterday.   It said growing numbers of British businesses were now looking to move towards ‘energy independence’ to protect themselves from the rising threat of future brownouts. ...


  • Marine crude oil transport – global voyage losses

    Paul Harrison, Consultant to the HMC-4A Marine Oil Transportation Database Committee, presents latest findings from analysis of the 2013 data on marine crude oil transport. The Energy Institute (EI) HMC- 4A Marine Oil Transportation Database Committee has been collecting and analysing worldwide oil shipping data for over 20 years and meets twice a year. The 2013 autumn meeting was held in Rio de ...

  • Ocean Thermal Energy conversion and the company bringing it to market: peace for our children

    Two centuries ago, U.S. President John Adams advised us of the importance of observing our world with clear eyes, “Facts are stubborn things; and whatever may be our wishes and passions, they cannot alter the state of facts and evidence.” Though there are some facts we all would rather not face, one of those unpleasant truths is that there are places in the world where the need for ...

  • Ocean Thermal Energy conversion and the company bringing it to market: clean water for our children

    Water is the most life sustaining resource on earth. Essential to all aspects of our human lives, it serves as the key ingredient in food and drink, helps us fabricate clothes, landscapes our favourite places, drives economic growth and feeds agricultural development. Our bodies themselves are 70% water. This liquid of life keeps us hydrated, catalyses crucial chemical reactions within our cells ...

  • 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 ...

  • Marine messages

     Europe’s seas are home to a rich and diverse array of species, habitats and ecosystems. Although vital for Europe’s economic and social wellbeing, many of these ecosystems risk being irreversibly damaged by human activities. ‘Marine messages’, a briefing from the European Environment Agency (EEA), provides an overview of the current state-of-affairs of European seas ...

  • Analytical solution of a kinematic wave approximation for channel routing

    The kinematic wave approach is often used in hydrological models to describe channel and overland flow. The kinematic wave is suitable for situations where the local and convective acceleration, as well as the pressure term in the dynamic wave model is negligible with respect to the friction and body forces. This is the case when describing runoff processes in the upper parts of catchments, ...
