Wind Power is simply the conversion of wind energy into a more useful from of energy using wind turbines. Although wind currently produces approximately \(3%\)% of world-wide electricity use in \(2010\), it still accounts for approximately \(21%\)% of electricity production in Denmark, \(18%\)% in Portugal, \(16%\)% in Spain, \(14%\)% in the Republic of Ireland and \(9%\)% in Germany.
With the advent of technology, the use of wind for electricity generation has been expanding rapidly recently due to the major breakthroughs in technology and an increasing, pertinent concern over the harmful emissions from conventional power stations associated with burning fossil fuels. As wind power is renewable and does not cause pollution, environmentalists choose this over fossil fuels as a preferable choice.
Although wind power on the surface looks seemingly a possible, viable solution to end the battle against environmental problems, but recent studies suggest that this may lead to long term effects on wildlife living in the immediate areas of larger wind farms. It may also possibly affect regional weather patterns as warmer areas affect the formation of cloud and even wind speeds.
Consider this example, usually at night the air closer to the ground becomes colder when the sun goes down and the earth cools due to convection currents. However this may not be the case on huge wind farms, where the motion of the turbines mixes the air higher in the atmosphere that is warmer, pushing up the overall temperature, possibly accelerating the drastic climate change.
In fact in Texas, the area that is now covered by four of the world's largest wind farms, Satellite data found that over a decade the local temperature went up by almost \(1^0 C\) as more turbines are built in that area.
In a nutshell, even renewable sources of energy still have its drawbacks ultimately. So, should we support or abolish the use of this "environmentally-friendly" wind power. If so or otherwise, why? What are some other disadvantages of wind energy? How could we make wind turbines more efficient in environmental and energy-efficient aspects? These are your food for thought to discuss about. Hope it isn't too lengthy.....
