In Support of Wind Energy: The Foundations that Underlie Wind Projects
Foundations are critical to the success of a wind turbine project, and since foundation types are as varied as the earth conditions and types of structures being supported, we examine below some of the considerations involved in foundation selection such as siting, cost, and geotechnology.
Wind Powered Engines And The Elusive 59% Efficiency
Images of the 3 bladed wind engines are now seen everywhere and they have come to symbolize intelligent energy creation for virtually everyone but are these designs actually the most efficient ones possible? No one seems to know their efficiency so that vital issue is completely overlooked and rarely discussed. Efficiency is important to all.
Wind energy: Why is project certification so important?
What can you do as an investor to protect your wind farm investment? What can you do as a wind farm owner to secure your wind power production? How can the trust of insurance companies for wind farm projects be improved? The solution is to find an independent inspection, testing and verification company that combines technical consultancy with project certification.
Condition Monitoring for Wind Turbines
Condition Monitoring involves a set of activities wherein various components of the wind turbine are regularly inspected and monitored. The process gathers condition parameters of the machinery, such as lubricant condition, temperatures, vibration data and visual inspection results, on a regular or permanent basis. A minor failure in a key component of the wind turbine can cause down-time and severe losses
Interview - 20% Energy from Wind by 2030 - A Reality Check
A discussion about the future of the wind energy industry and the goal of 20% Energy from Wind by 2030
Interview - Community Winds Coming of Age
One of the major benefits of Community Wind projects is that they provide incremental jobs, wages and business income in communities, since ownership is retained and profits are recycled locally. In addition, the community has a significant amount of control over management of the project and there are opportunities for members of the community to have a direct financial stake in the project.
Offshore Wind
The US has installed over 25 gigawatts of wind, and thanks to hodge-podge of policy incentives, research and development, and private investment wind has become the poster-child of renewable energy and at the utility-scale has achieved grid-parity with conventional fossil-fuel energy. However not a single kilowatt of offshore wind has been developed, despite it being a stronger and more consistent energy source than its counterpart on land, closer to large populations where the energy is needed, and already proven commercial technology.
The Maine Wind Industry Initiative
Wind power development doesn't deal with a single industry. There are steel workers, engineers, precision manufactures, boat builders, construction crews, composite technologies, and marine technologies. The Maine Wind Industry Initiative brings these partners under one roof, so that they can network and solve problems working together.
WHY 2 BLADED ROTORS MAKE SENSE
One of the greatest advantages of two bladed rotors is the cost savings realized by the elimination of a blade. Although it can be argued that a teetering hub is more complex and costly than the rigid hub of a three bladed rotor, technological advances have reduced this complexity and cost. For example elastomeric bearings for the teeter hinge have eliminated the need for ball or roller bearings and the maintenance associated with these components.
Better Wind Turbine Transmission
This article is intended as a suggestion for manufactures of, and users of large wind turbines. Users have noted reliability problems mostly due to the use of a mechanical gear transmission required to transform the relatively slow rotational speed of the large turbine hub to the required shaft speed of the synchronous alternator.
MIT Clean Energy Entrepreneurship Prize
"FloDesign Wind Turbine Corporation is going to revolutionize the way we capture energy from the wind," says CEO, Stanley Kowalski III. "Our wind turbine will produce more wind energy with less impact on the environment. Our turbines are smaller, can function in a variety of climates, and can work closer to the ground."
SMALL-SCALE WIND ENERGY
The document is intended to provide you with some basic information about wind energy systems from approximately 500 W up to 50 kW.
Need for Wind Energy Professionals Will Rise
Wind energy training will prove to be one way to put those who receive this education on the cutting edge of a whole new technology as people look to find alternative energy sources.
SGS Conducts QHSE Management for the Belwind Bligh Bank Offshore Wind Farm in Belgium
In July 2009, SGS was assigned a contract to carry out Quality, Health, Safety and Environmental (QHSE) Management for the Belwind Bligh Bank Offshore Wind Farm in Belgium. SGS provides QHSE Management activities during the design, manufacturing and installation phases of the wind farm project in order to assure high quality standards and a safe project execution.
Testing times for wind turbines
John McNab, assistant product manager at the Seaward Group, looks at what's involved in the protection of wind turbine electronics and electrical systems from lightning strikes and the latest in digital microhmmeter earth bonding measurement and related safety testing.

HPS EnduraCoilTM Cast Resin Medium Voltage Transformer
HPS EnduraCoil is a high-performance cast resin transformer designed for many demanding and diverse applications while minimizing both installation and maintenance costs. Coils are formed with mineral-filled epoxy, reinforced with fiberglass and cast to provide complete void-free resin impregnation throughout the entire insulation system. HPS EnduraCoil complies with the new NRCan 2019 and DOE 2016 efficiency regulations and is approved by both UL and CSA standards. It is also seismic qualified per IBC 2012/ASCE 7-10/CBC 2013. Cast resin transformers are self-extinguishing in the unlikely event of fire, environmentally friendly and offer greater resistance to short circuits. HPS also offers wide range of accessories for transformer protection and monitoring requirements.
