  • Wind Generators as Role Models

    Advanced speed control methods are available for the regulation of wind generators. Working together with SET Sustainable Energy Technologies GmbH, Sulzer made use of one of these new concepts on pumps for the first time and implemented it with great success on a feedwater pump in a refinery. Unregulated pumps consume unnecessary drive energy when demand fluctuates. By controlling ...

  • Hybrid Solar/Wind plant in Madagascar

    Distinguished among the winners of the Sunidarity initiative, the World Energy Foundation announced Thursday that it had installed in the extreme south of Madagascar a concentration photovoltaic equipment (CPV) provided by Soitec, one of the leading manufacturers and suppliers of global CPV systems. Called Plug & Sun, this equipment allows an autonomous solar-electric generation in areas ...

  • Dynamic validated model of a DFIG wind turbine

    This paper presents the development and qualitative validation of a doubly-fed induction generator (DFIG) wind turbine model that is represented in terms of behaviour equations of each of the subsystems, mainly the turbine rotor, the drive train, the induction generator, the power converters and associated control systems and a protection system. Simulation results obtained from the models are ...

  • Finite element structural study of the VGOT wind turbine

    We analyse the implementation of the finite element method to simulate the structural behaviour of the blade-wagons of variable-geometry oval-trajectory (VGOT) Darrieus wind turbines. The key feature of a VGOT machine is that each blade, instead of rotating around a central vertical axis, slides over rails mounted on a wagon formed by a tubular reticulated structure supported by standard train ...

  • Adoption hurdles and challenges with small wind turbines

    Adoption Hurdles and Challenges with Small Wind Turbines Wind energy is very promising. It can be harvested without any costs, and like solar panels, wind turbines are environmentally-friendly. However, such machines are not living up to their potential. Some users have reported low efficiency rates, unpredictable performance and costly adoption barriers. ...

  • Energy Security

    Renewable & Clean Energy Solutions to Secure Energy Independence from Foreign Oil. FOREIGN OIL: As imports grow and world prices rise, the amount of money we send to foreign nations every year is soaring. At current oil prices, we will send $700 billion dollars out of the country this year alone — that’s four times the annual cost of the ...

  • 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 ...

  • 115. Calgary’s wind powered LRT an incredibly successful system: Nenshi

    The C-train in Calgary is one of the greatest examples of electrified transport in Canada. It is overwhelmingly popular with residents – it boasts an average weekday ridership of 325,000. It has kick started smarter, denser development around its stations. And best of all it and the City of Calgary’s operations are 100 per cent powered by renewable energy. “It's hugely important ...

  • Nominations Open for the Inaugural Wind O&M Excellence Awards

    London, Feb 4th 2015 –Wind Energy Update, in collaboration with E.On and Danish Wind Power Academy Americas, have announced they will host the first Wind O&M industry awards ceremony at the leading North American Wind Operations & Maintenance (O&M) Dallas Summit (April 13th-15th) These are the first awards of their kind and the only ceremony in North ...

  • International investment in CSP South Africa: New data and a Building Energy case study

    Introduction: A renewable energy market of extraordinary growth In just four years, South Africa has gone from being a coal-dependent economy to a prime destination for renewable energy investment. Largely propelled by the Renewable Energy Independent Power Producer Procurement Programme (REIPPPP) which commenced in August 2011, the scheme has procured 79 projects with a capacity of 5,243 ...

  • The Bayl Primary School at Hong Hu lake (China)

    In June 2006 Fortis installed a Montana (5 kW) hybrid system at the Bayl Primary school at lake Hong Hu (Hubei province) in China. At the lake there live about 500 families on boats who life from catching fish and aquatic production on the lake and the sales of it. The families live in houseboats on the lake. Because they do not have any chance for grid connecting , wind energy and solar energy ...

  • Building New Industries and Creating New Jobs in a Plan B Economy

    Building a new economy, one that can sustain economic progress, involves phasing out old industries, restructuring existing ones, and creating new ones. This new economy will be powered by renewable sources of energy, will have a more diverse transport system--relying more on rail, buses, and bicycles, and less on cars--and will recycle everything. For example, coal use will be phased out, ...

  • A new EE resource: Distributed people

    Energy efficiency is often described as the invisible resource. It improves our energy supply without any of the usual industry trappings: smokestacks, wind turbines, transmission lines and poles. This is one of its virtues.But efficiency’s invisibility also causes problems. Because it operates out of sight – inside walls, underneath lampshades, and in factory motors — efficiency tends to attract ...

  • A small island in the Indian Ocean offers big lessons on clean power

    The Indonesian island Sumba is working to provide 100% renewable electricity to all 650,000 residents by 2025. As the sun sets on the small Indonesian island of Sumba, Danga Beru Haba begins weaving under the glow of a single incandescent lightbulb, the only one in her home. Although she is tired from working dawn to dusk in the fields surrounding her village of ...

  • Smart Grid: The game

    In his best seller “Outliers,” Malcolm Gladwell shows that it is not equipment failure or storms that typically cause planes to crash, but wrong decision-making. Much the same can be said for the power grid crash that took down a large swath of the Northeast in August 2003. The emerging smart grid is supposed to make our power system more reliable. The bad news is that it also will add complexity ...

  • No Place Is Too Far

    The remote location of hydropower stations is often a great challenge when major repair work is necessary. The refurbishment of a large generator in the Scottish Highlands shows how Sulzer finds cost-effective service solutions even in places miles from nowhere. Much of the UK hydroelectric capacity was built during the 1950s. These installations have performed extremely well, especially ...

  • What will it take to integrate renewables into the power grid? Ask a bicyclist.

    When it comes to fitting into the current system, bike commuters and electrons have a lot in common. There’s nothing quite like biking down clogged city streets, weaving in and out of traffic. For short distances, it’s faster than driving. It’s liberating. It’s fun. It also makes it painfully clear that most roads ...
