THE wind power sector has hit back at scathing criticism in Federal Parliament last week by an MP who described electricity generation by wind turbines as ludicrously inefficient. Sydney-based Liberal Craig Kelly claimed 3500 turbines would be needed to produce the equivalent output of one medium-sized conventional coal or gas-fired power station.
"The electricity they produce is 500% more expensive than electricity produced by coal-fired plants", he said. "Even if we built these 3500 steel windmills, we would still need a gas-fired power station as a backup, for when the wind doesn't blow, the power doesn't flow. "Overseas studies have suggested that we could actually lower our emissions of CO₂ if we did away with wind turbines altogether and just ran gas power stations inefficiently".
The Clean Energy Council later issued an invitation to Mr Kelly to tour a wind farm and learn how it drives investment in local communities. South-west Victoria is one of Australia's fastest-growing regions for wind farm investment. "The cost of wind power can be about the same as brown coal in many cases or only marginally more", the council's policy director Russell Marsh told The Standard.
"Wind power is currently the cheapest type of renewable energy that can be rolled out on a large scale and is expected to play a major role under Australia's renewable energy target of 20% by 2020". Mr Marsh said there was no evidence new power stations had to be built solely to back up wind generation. "When wind power is being fed into the system, less power is required from carbon-intensive sources to meet our energy needs".

Japan's FiT in July is among the highest in the world. It's clear that Japan's FiT will shake the renewable energy market. New solutions will be showed in Japan. This is it!
Floating Wind Turbine is one of the best solutions for USA and UK. U.K has more install places around its shores than any other in the world. USA has Atlantic Coast. As you know, they have to reduce Vibration to install Floating Wind Turbines on the sea. Because, it makes many kinds of problems! Vibration’s caused by wind, waves and external forces. New Floating Body Stabilizer for Floating Wind Turbines has been created in South Korea. The Floating Body Stabilizers generate drag force immediately when Floating Wind Turbines are being rolled and pitched on the water. Recently, this Floating Body Stabilizers have been used to reduce vibration of Floating Solar Panels in South Korea. You can see New Floating Body Stabilizer videos in YouTube. http://youtu.be/O2oys_YHhCc, http://www.youtube.com/watch?v=nA_xFp5ktbU&feature=youtu.be.
