Sycamore design could revolutionise wind power
A sycamore seed design may be set to revolutionize the wind power industry.
British engineers have designed a giant wind turbine called the Aerogenerator that would rotate on its axis mimicking the way sycamore seeds fly.
The Aerogenerator has two arms coming out of its base to form a V-shape, with rigid "sails" mounted along their length. The arms act like aerofoils as the wind passes over, helping to generate lift.
It would measure nearly 900 feet from tip to tip and could generate Read more [...]
Australian wind farms suffer
Australia:
Small wind-energy companies fear privatisations of power stations and retailers in New South Wales and Queensland could weaken competition in the electricity market, hindering their capacity to contribute to the federal government's 20 per cent renewable energy target.
Under the renewable energy target, retailers are required to buy or create enough renewable energy certificates (RECs), each representing one megawatt-hour of emissions-free electricity, to meet an annual target.
But Read more [...]
£2bn wind farm to be built off Wales
One of the largest offshore windfarms in the world, is to be built off the coast of Wales in the UK.
The £2bn Gwynt y Mor windfarm will have 160 wind turbines around 10 miles off the north Wales coast near Colwyn Bay and Llandudno.
Gwynt y Mor will be Wales' largest wind farm, capable of powering around 400,000 homes, and preventing the release of 1.7m tonnes of carbon dioxide every year.
The RWE Innogy-led project is expected to be completed in 2014.
It is claimed some 1,000 jobs could Read more [...]
Wind power growing in confidence
Wind is the number one source of new electricity-generation installations in both Europe and the U.S. and has been for the last year or two, according to green energy analysts.
"Wind is the one renewable energy source that, currently, is competing directly with coal and natural gas for electricity from new power installations." says GreenTech Opportunies analyst Peter Cox.
Wind and natural gas combined accounted for about 80% of new capacity added to the U.S. electrical grid.
"Wind energy Read more [...]
Biomass the “new wind” says KPMG
Biomass power plants fuelled by organic matter such as food waste, wood chips and sewage could be more lucrative than wind farms says the accountancy firm KPMG in their annual renewable energy survey .
“Biomass looks set to be the ‘new wind’,” said Andy Cox, energy partner at KPMG who led the research. “Biomass plants have the potential to yield much higher returns than other renewable sources. A well-executed plant can deliver substantially greater economies of scale than wind. And Read more [...]
Google invest in wind farms
Google has invested $38.8 million in two North Dakota wind farms. This is the first direct investment by Google in utility-scale renewable energy generation.
Utilising one of the world's richest wind resources - the winds of the North Dakota plains, the two wind farms produce 169.5 megawatts of power and can light up around 55,000 homes.
In an official statement Google says "Through this $38.8 million investment, we're aiming to accelerate the deployment of renewable energy — in a way that Read more [...]
China’s Wind Farm Push
China is rushing forward with its wind energy plans with the pace surpassing even the most optimistic projections.
After setting an original goal of 30 gigawatts of installed wind power by 2020, the government recently said that could be raised to 100 gigawatts as installed capacity has doubled each of the last four years.
From almost nothing a few years ago, China had 12.2 gigawatts of installed wind power by the end of 2008 as power companies have rushed to meet government mandates to raise Read more [...]
Wind farm companies hit back over “dangerous” claims
The wind energy industry has vigorously rejected new research from the US suggesting some residents living close to wind farms are susceptible to a collection of health risks dubbed "Wind Turbine Syndrome".
Dr Nina Pierpont, a New York paediatrician, claimed this week that the noise and vibrations caused by wind turbines could impact the health of nearby residents. But the British Wind Energy Association (BWEA) accused the study of being based on an "unscientific" sample and running counter to Read more [...]
Wind farms are dangerous says pediatrician
A New York paediatrician has warned that living too close to wind turbines can cause heart disease, tinnitus, vertigo, panic attacks, migraines and sleep deprivation in groundbreaking research due to be published later this year.
Following studies of people living near wind turbines in the US, UK, Italy, Ireland and Canada for the past five years, Dr Nina Pierpoint has identified a new health risk called wind turbine syndrome (WTS).
She says the disruption of the inner ear’s vestibular Read more [...]
Cut back on wind farms and build nuclear plants says UK business group
UK: The CBI has called on the UK government to scale back on “overambitious” wind power and boost the role of atomic energy and coal.
