25.- Can wind farms cause climate changes ?

I would say that wind farms are very benefit for humans in enviromental impatcs.  

Compared to the environmental impact of traditional energy sources, the environmental impact of wind power is relatively minor. Wind power consumes no fuel, and emits no air pollution, unlike fossil fuel power sources. The energy consumed to manufacture and transport the materials used to build a wind power plant is equal to the new energy produced by the plant within a few months. While a wind farm may cover a large area of land, many land uses such as agriculture are compatible, with only small areas of turbine foundations and infrastructure made unavailable for use.

We must remember that wind farms do not generate wind airflow, conversely wind farms only transform winds to generate "Green Energy" , Clean and durable Electricity.

 Only critics to wind farms come from  reports of birds and bats mortality at wind turbines as there are around other artificial structures. The scale of the ecological impact may or may not be significant, depending on specific circumstances. Prevention and mitigation of wildlife fatalities, and protection of peat bogs, affect the siting and operation of wind turbines.

                  The Gansu Wind Farm in China is the largest wind farm in the world, with a target capacity of 20,000 MW by 2020 

In order to underline afirmations we search declarations for  WWF Scotland’s director Lang Banks  in 2014 WheaterEnergy Report about investment in wind and solar power.

“Without doubt, 2014 was a massive year for renewables, with wind turbines and solar panels helping to ensure millions of tonnes of climate-wreaking carbon emissions were avoided. With 2015 being a critical year for addressing climate change internationally, it’s vital that Scotland continues to press ahead with plans to harness even greater amounts of clean energy.
