Cost of offshore wind energy reaches record low

Prices for electricity generated by offshore wind farms continue to fall Offshore wind energy systems are often considered highly expensive, but as new technology become available, the cost of these wind farms is beginning to fall. In Sweden, a new record has been set for the world’s least expensive wind farm built at sea. The Vattenfall wind farm is now capable of selling electricity for proximately $50 per megawatt-hour. According to Magnus Hall, the chief executive of the Vattenfall wind farm, the deals the energy system has managed to establish…

New massive offshore wind turbine will be low-cost and have huge blades

The blades of the turbine will be longer than two football fields. A large group of researchers are working together to build a low-cost 50 MW (megawatt) wind turbine for offshore wind energy production. This is big alternative energy news because the vast majority of current wind turbines are 1 to 2 MW, with the largest typically having a capacity of 8 MW. For a turbine to be able to produce 50 MW of energy, it would need to have blades that measures over 650 feet in length, which is…

Wind energy sets new record in the US

Wind capacity now produces 70 GW of electrical power Wind energy has set a new electrical generation record in the United States, according to data from the American Wind Energy Association. The data shows that the country’s wind capacity can now generate enough energy to power a record setting 19 million homes. The U.S. now has some 70 gigawatts of installed wind capacity. As such, 2015 may go down as the year wherein wind power has managed to establish a significant foothold in the country. Federal tax credits will ensure…

Wind energy may provide more than power to future amusement park

Wind farm may be transformed into an eco-themed amusement park. Qurrent, a forward-thinking Dutch renewable energy company, has recently unveiled its plans to transform a wind farm into a sustainable theme park, which would not only feature wind energy but wind turbine rides. If its plans do become a reality, Qurrent, in collaboration with Jora Entertainment, will have created the first sustainable theme park in the world, reported Inhabitat. The park will include the world’s tallest spiraling water slide. The company has designed the park plan in collaboration with Dutch…

Wind turbines of the future: Two blades may be better than three

Wind turbine energy may look different in the years to come. Although wind farms featuring three-bladed wind turbines is the industry standard, some turbine manufactures, who are looking for ways to boost the efficiency of these huge devices to improve their wind capturing capabilities, are building two-bladed turbines and spinning the rotor 180 degrees to face downwind, to see if this will improve efficiency. A two-bladed prototype is being built by 2-B Energy. According to The Maritime Executive, 2-B Energy, a company from the Netherlands, will be constructing a prototype…

Cost of wind energy could be lowered by new technology

University of Sheffield engineers may have found a way to make wind power cheaper. The university engineers have developed a new method to forecast when internal wind turbine bearings will fail, which would enable engineers to predict when a turbine may need maintenance. The technique can also be used to prevent unexpected bearing failures, which could help save the wind energy industry money. The technique uses ultrasonic waves to help engineers with their predictions. According to a Phys.org news article, the new method was developed by Wenqu Chen, a Mechanical…

Wind turbine energy may find new home in viaducts

Viaducts could be the ideal location for wind turbines, study finds. Unlike solar energy, which can be installed on land, roofs, and many other places, wind turbine energy is far more limited, and typically requires a vast amount of land in the middle of nowhere or needs to be built offshore for it to generate the amount of power that makes installing the massive turbines worthwhile. However, a new study has found that viaducts may prove beneficial to the future of wind energy. Wind turbines could be built within the…

Owls could provide the solution for quieter wind turbines

New research may have found a way to reduce the sound produced by wind turbine energy generation. A team of researchers at the University of Cambridge have discovered that the flight feathers found on the wings of large owls may hold the key in helping scientists find a way to develop technology that would decrease the amount of noise generated by wind turbines, which would be a huge bonus for the wind energy industry, which regularly receives complaints from people who live near wind farms that say the sound these…

New GE technology could improve wind energy generation

GE is showing off its new wind turbine design. After two years of working on a new turbine design to help improve wind energy generation, GE (General Electric) has finally revealed its latest wind power technology called the ecoROTR, which some might find looks silly with its “big nose” appearance, but if the company’s theory is correct, this new design could result in larger turbines with greater efficiency for windy areas that are presently too difficult to reach for the industry. The large dome on the new turbines can capture…

Bladeless wind generator could be the next big thing for wind energy

An innovative company wants to change how energy is generated from wind. Spanish tech startup Vortex Bladeless is taking a new wind energy generation approach and, instead of using wind turbines with rotating blades, the company has reinvented the standard wind turbine model, creating Vortex, which is essentially a tall mast that looks somewhat like the pole of a standard turbine without the blades. According to the company’s official website, Vortex will be more environmentally friendly, more cost effective, and a more efficient way to produce energy compared to current…

Futuristic wind turbine to house people and generate green power

Proposed wind energy project in the Netherlands could redefine renewable energy generation. A new project, The Dutch Windwheel, is a massive proposed and unique wind turbine for Rotterdam, a city in the Netherlands, which will not only generate energy from the wind, but will feature apartments, hotel rooms, and a restaurant along the structure’s exterior. The Dutch Windwheel would utilize special wind energy technology. The huge and innovative environmentally-friendly structure would use electrostatic wind energy converter (EWICON) technology to produce electricity without requiring moving parts, as is the case with…

New technology helps study potential of offshore wind energy in the US

Two data collecting buoys will help determine the energy-harnessing possibilities of this sea-based renewable source of power. In the United States, the full potential of offshore wind energy has yet to be harnessed and part of the reason for this is that information regarding its power possibilities is lacking, but the US Department of Energy’s (DOEs) Pacific Northwest National Laboratory (PNNL) is seeking to rectify this issue with two buoys that will be dropped into costal water and are equipped with advanced data collecting capabilities. The buoys have nearly completed…

Stealth technology comes to the wind energy space

New technology may be put to use at a wind farm in France A new kind of wind farm could soon be under construction in France. The wind farm is meant to serve as a demonstration for new wind turbine technology, which would create “stealth” turbines. Wind farms have often been criticized for their impact on ground radar systems. The blades of a turbine interfere with radar signals by returning them to their origin. As such, ground radar systems can sometimes confuse wind farms for aircraft and weather systems. Aircraft…
