    1. The ZEBRA (Zero wastE Blade ReseArch) consortium has produced the first prototype of its 100 per cent recyclable wind turbine blade.

      First Fully Recyclable Wind Turbine Blade Rolls Out

    1. How offshore wind and renewable power-to-X can help solve Europe’s energy crisis

    1. Die europäischen Produzenten von Windturbinen Mädchen enorme Verluste. Die Hauptgründe sind Kostensteigerungen und logistische Probleme. Hinzu kommen Investitionen für neue, stärkere Modelle und chinesische Konkurrenz. Ein zusätzliches Risiko könnte die Förderung der US-Turbinen-Industrie durch die Biden-Administration darstellen. Die europäischen Produzenten erwarten mehr Unterstützung durch die Regierungen, um Kompetenzen in Europa zu halten.

    1. Renewable energy critics argue that wind and solar are not reliable sources because of their variability. Others argue that wind farms encroach on pristine environment and destroy a country’s natural habitat, as is the case with the installation of thousands of wind turbines on scores of Greek islands in the Aegean Sea. How would you respond to such concerns, and are there ways around them?
    1. if we want to deliver a thousand terawatt hours a year using these systems you could use 142 00:29:07 coal-fired power stations or 30 000 solar pv arrays or 12 309 wind turbine arrays of average size 00:29:18 where each array is like 10 win windows this is this is where we're getting the extra numbers from so each of these sites will have to be built and constructed and maintained and then when they wear out they need to 00:29:30 be decommissioned so renewables have a much lower energy return on energy invested ratio than fossil fuels and they and the the truth is they may not be strong enough to power the next industrial era 00:29:45 so gas and hydro power generation has to balance with demand supply and demand has to balance otherwise the grid will age

    1. LOPINOD is also being used to fund the development of a Low Carbon Plan. This plan will focus on the full spectrum of renewables including wind, solar, marine source heat pumps and tidal. It is hoped that we will become a hub for all green energy going forward, building on our existing involvement in the wind farm industry.

      Beachhead for solar, tidal, marine source heat pumps as well as wind energy

    1. Forexample, in a 2–MW wind turbine, the weight of the rotorand the tower is typically about 250 tons [10]. As reportedbelow, a kite generator of the same rated power can beobtained using a 500–m2kite and cables 1000–m long, witha total weight of about 2 tons only.

      Is this a reasonable claim?
