Some of the most significant objections to wind farms have come from aviation authorities.

Rotating wind turbines have been found to confuse radar systems, potentially compromising air traffic control. Air traffic controllers say they have to differentiate between aircraft and wind turbines.

The power of wind was invoked Sunday in one of the world’s most troubled nations when Pakistan and the US agreed on a public-private partnership to develop a 150-MW wind energy facility capable of creating enough electricity for 600,000 local homes.

“This project represents a meaningful, environmentally sound step toward addressing Pakistan’s energy crisis,” Ambassador Richard Holbrooke, U.S. Special Representative for Afghanistan and Pakistan, said in a press release.

“Partnership with the private sector will also demonstrate the potential of investing in the power sector in Pakistan.”

Imagine a world two decades from now in which a new wind turbine is installed every seven minutes.

That impressive scenario was raised last week in Beijing just before the China Wind Power 2010 conference by Sven Teske, Senior Energy Expert from Greenpeace International.

Teske was commenting on the Global Wind Energy Outlook 2010 report which found wind power could provide about one-fifth of the world’s electricity by 2030.

Ward Van Hout, a student studying Aerospace Engineering at the Technical University of Delft in the Netherlands, tells EWEA why he is a fan of wind energy and why he adopted a wind turbine as part of EWEA’s 2010 campaign…

EWEA: Why do you support wind energy?

Van Hout: I support wind energy because it is the future. Wind energy will help us to overcome the shortage of fossil fuels. There has been an enormous increase in world population which means a drastic increase in energy consumption. And with this comes more and more pollution, higher CO2 concentrations, etc. An excellent alternative is wind energy. On Earth, sufficient wind is available for our energy needs. Strikingly, there is 200 times more wind energy available than current energy demand. Wind power is solar power, meaning that as long as the sun is giving us heat, we can make use of wind turbines to collect that power. It is clear that wind energy is the driving power of the 21st century – the renewable energy age!

Be it a flat-pack chest of drawers or bedside lamps, most of us have bought something from Ikea. And now, the Swedish chain well-known for creating a revolution in home furnishings is at the forefront of a hopefully incoming tide of companies to back wind power.

Ikea has bought six German wind farms, adding to its portfolio of four French wind farms purchased last year and bringing the total number of wind turbines the company owns to 52. The German farms provide enough electricity to power 17 Ikea stores, and in total the firm can now meet10% of its electricity needs with wind power.

The Financial Times reports that Ikea intends to make further investments in wind and solar power in order to meet its long-term goal to secure all its electricity needs from renewable sources.

“We are conscious of our impact on people and the environment, so we feel duty bound to act responsibly in all we do,” Mikael Ohlsson, Chief Executive of Ikea, told the paper.

However, Ikea’s green credentials were tarnished last year when the company was found guilty by French courts of building a new storage unit close to Marseille on envrionmentally sensitive land, Spiegel Online reports.

Ikea joins Google – another company that has invested in wind power. In May, the internet giant invested in two wind farms in the US that generate 169.5 MW of power, enough to provide electricity for more than 55,000 homes.
