  • Animation: How Wind Turbines Work

    The windmill, which converts wind into rotational energy to mill grain or pump water, has been around since antiquity. It’s even been claimed that Ancient Babylonians planned to harness wind as early as almost 4,000 years ago, as part of a scheme for one of Hammurabi’s ambitious irrigation projects. By the end of the 19th century, wind energy took on a whole new meaning as engineers ...

  • Full-energy-chain greenhouse-gas emissions: a comparison between nuclear power, hydropower, solar power and wind power

    Fair comparison of the climate impacts from different energy sources can be made only by accounting for the emissions of all relevant greenhouse gases (GHGs) from the full energy chain (FENCH) of the energy sources. FENCH-GHG emission factors of most of the non-fossil fuel energies are lower than those of the fossil fuels that are in the range of 500-1200 g CO2/kW h(e). The improvement ...

  • Thermodynamic analysis of an integrated gasification combined cycle power plant: effect of nitrogen supply on system performance

    A comprehensive thermodynamic analysis of a conceptual integrated coal gasification combined cycle power plant is presented. Energy and exergy efficiencies and exergy destructions of each sub–unit are calculated. The effect of nitrogen, which is supplied from the Air Separation Unit (ASU) of the gasification unit to the combustion chamber of the gas turbine (GT) cycle, on system performance is ...

The first calls for more use of wind ...

  • What’s the Future of R&D in the Wind Industry?

    When the wind industry finally reacted to the world’s financial crisis—it didn’t fully hit us until 2010—at once, we lost both an incredibly vibrant global wind market and sufficiently robust profit margins. The market recovery is rebounding nicely now, thanks largely to government incentives, but profit margins will probably never fully recover—at least, not to the ...
