  • Wind turbine controlling of the future

    Higher, more robust, more reliable: Parallel to the growing requirements for wind turbines, the requirements for monitoring sensors grow as well. But how can wind sensor manufacturers fulfil these wishes? And how should a future wind sensors look like? After analysing the current conditions and trends on the wind energy market, our CEO Klaus Hirzel compiled a wish list for future wind sensors. ...

  • Are wind turbines economically viable in Britain?

    If Britain establishes wind energy as their main energy source, they will be able to create a large number of new job opportunities. This can provide a huge influx of job opportunities in the short run since the implementation of wind turbines require a lot of manpower. Moreover, the maintenance of these wind farms can give life to a considerable amount of sustainable jobs. Monitoring the wind ...

  • 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 ...

  • The Real Cost Associated With Neodymium Wind Turbines

    According to a research organized by a group of UK scientists, it is predicated that 15% of the country’s energy requirements in the year 2020 are expected to come from renewable energy sources. They have also considered about the wind farms that are popping in every corner of the country to come into this conclusion. These reports have created several contradictions among people as well. ...

  • A new design of a highly efficient hydraulic turbine on the basis of the specific hydrodynamic effect

    Traditional free flow turbines slow down water stream using its kinetic energy. This article describes a method for deriving energy from a free water stream using a unique hydraulic turbine which unlike traditional hydraulic turbines speeds up the water stream using potential energy thanks to a specific hydraulic effect. The article also describes a method of mathematic calculations of output ...

  • Ocean Thermal Energy and Water Production

    Introduction The scarcity of potable water is a growing problem worldwide, particularly in arid regions and among developing countries. Compounding this problem is the increasing contamination of freshwater sources, which comprise only about 2.5% of all water on Earth. Of this small portion, only 0.5% of the total fresh water available is found in easily accessible sources such as ...

  • Idaho Water District’s new Hydroelectric project - case study

    This Irrigation District north of Twin Falls installed a new run of the river hydroelectric facility. In order to protect their new turbines, they installed this Traveling Water Screening System. The majority of debris consists of weeds, tumbleweeds, aquatic plants and urban debris. The 5 screens at this location drop debris on a 60’ long conveyor. The conveyor carries the debris to an ...

  • Wind Energy Technologies: Technology, Market and Costs

    Technology Overview   These large wind turbines turn Midwestern wind into utility electricity. Wind turbines convert the power in the wind into electricity. By extracting the kinetic energy in the wind, wind turbines generate mechanical power. In the past, mechanical wind machines were widely used for specific tasks, such as pumping water or grinding grain. Today, wind ...

  • Eco House, Lanarkshire

    A Gaia-Wind turbine is the principal wind energy source in this eco house in Scotland. The house is all electric, consuming 50% of produced energy, and offsets 16 tonnes of CO2 annually. Average annual energy production: 28,000 kWh Background Mr Taylor is an architect by profession. He designed his own eco house incorporating a Gaia-Wind turbine as the principal wind ...

  • Vattenfall to invest over €1 billion in North Sea wind farm

    Swedish power giant Vattenfall announced that it will invest more than €1 billion (about $1.4 billion U.S.) in the DanTysk project, a 280 megawatt (MW) offshore wind farm to be located in North Sea waters between Germany and Denmark. Vattenfall has formed a joint venture with Stadtwerke München GmbH (SWM; Munich, Germany) to develop the DanTysk facility, with Vattenfall holding a 51% ...

  • Offshore wind installation vessel capacity to tighten after 2020

    The existing fleet of turbine and foundation installation vessels is well suited to serve the European offshore wind market in the short and mid-term but it will not be sufficient to support installation demand after 2020, Michael Guldbrandtsen, senior consultant at MAKE Consulting, told Wind Energy Update. The next 2-3 years will continue to be dominated by orders for jack-up ...

  • Intro to Hydropower Part:2 Measuring head & flow

    Measuring the stream course—Anna and Joe work downstream, shooting vertical drop (head) with a sight level, and getting a rough measurement of the pipe run at the same time. Small-scale hydro is the only renewable energy source that works for you 24 hours a day, 7 days a week. In the first article in this series (HP103), I explained the basics of hydroelectric system theory, and ...

  • 2013 to be Record Year for Offshore Wind

    Offshore wind power installations are on track to hit a seventh consecutive annual record in 2013. Developers added 1,080 megawatts of generating capacity in the first half of the year, expanding the world total by 20 percent in just six months. Fifteen countries host some 6,500 megawatts of offshore wind capacity. Before the year is out, the world total should exceed 7,100 megawatts. Although ...
