Warning lights on wind turbines in South Australia, designed to alert pilots of the turbines presence, will be progressively turned out in August in September, spurring safety concerns for pilots and aircraft in the area.
Note: The total amount of economically extractable energy available from the wind is considerably more than present human energy use from all sources. An estimated 72 terawatts of wind energy on the Earth potentially can be commercially viable, compared to about 15 terawatts normal world energy consumed from all sources in 2005. These numbers are in spite of the fact that not all the energy of the wind flowing past a given point can be recovered.Throughout history the wind has been used directly to propel sailboats or converted into mechanical energy for pumping water or grinding grain, but the principal application of wind power today is the generation of electrical energy. Enormous wind turbine farms are normally attached to the local electric power transmission network, with smaller wind generators being used to provide electric power to isolated places. Power companies increasingly purchase excess electricity generated by the lower capacity home size turbines. Generated wind energy as a power source is a favorite of many environmentalists as an alternative to fossil fuels, as it is everywhere, renewable, globally available, clean, and has lower amounts of greenhouse gas emissions, even though the building of wind generating collectives is not universally applauded due to their visual impact and possible effects on the Eco-system. The intermittency of wind seldom creates challenges when using wind turbines to provide a low proportion of total usage. When wind is considered for a larger proportion of usage, additional costs for compensation of intermittency are believed to be modest.It is important to mention that there are diy guides available that allow almost anyone to build a quality wind generator with readily available components at a very reasonable cost. http://diyenergy.newagelinx.com/review.htmlThe Snowtown Windfarm is located about 100 miles north of the state capital, Adelaide. TrustPower owns the farm. There are approximately 22 airports in the southern region of Australia, one of which is the Adelaide Airport, the fifth busiest airport in the country.Other active stocks are Sauer Energy (OTCBB: SENY), Arista Power (OTCBB: ASPW) and Wind Works Power (OTCBB: WWPW)."Those requirements have now changed with the Snowtown wind farm towers now only required to be marked on aeronautical navigation charts as potential hazards," said Rodney Adhern, TrustPower Australia business development manager. "We have worked through a process with the Civil Aviation Authority that now enables us to turn off the lights."Contact: Eric Jensen www.ionewswire.com 516.942.4910
