In recent years, wind turbines have become a common sight across the world, as countries race to do their bit to cut emissions and provide a more sustainable form of energy for the future.<\/p>\n

But, how much do we really know about these structures and the process of generating power from wind?<\/p>\n

Here are ten facts that might surprise you\u2026<\/p>\n

10. China is top of the list:<\/strong> After a big push to build turbines \u2013 at one point it was building two an hour<\/a> \u2013 China leads the way when it comes to wind power, with about a third of the entire global capacity. The United States has the second highest capacity for wind power, Germany is third, India fourth and Spain fifth.<\/p>\n

9.\u00a0Denmark produces a big proportion of energy from wind:<\/strong> While China might be the biggest producer, Denmark is able to get more than 40% of its energy<\/a> from wind. On particularly windy days, it is even able to produce 140% of the nation\u2019s electricity needs from wind.<\/p>\n

8.<\/strong>\u00a0A lot goes into a wind turbine:<\/strong> There are about 8,000 different components making up the structures that you see.<\/p>\n

7.\u00a0They can spin very quickly.<\/strong> While speeds vary depending on the size and weather conditions, at full speed the tips can spin at an estimated 180 mph.<\/p>\n

6.\u00a0Turbines need to be weather-proofed:<\/strong> Given that they\u2019re out in all weathers, the surface of a wind turbine needs to be prepared for everything Mother Nature throws at it. The surface needs to be properly prepared \u2013 perhaps using blasting equipment<\/a> \u2013 so that the coating will withstand the great outdoors. With proper construction, a turbine can last for up to 25 years.<\/p>\n

\"Wind<\/a><\/p>\n

5. Turbines are getting bigger:<\/strong> Earlier this year the world\u2019s biggest turbine was unveiled in Denmark<\/a>. It is 722ft (or 220m) tall, with propellers that measure 263ft (or 80m). That\u2019s about half the height of the Empire State Building (to its tip).<\/p>\n

4. Turbines don\u2019t come cheap.<\/strong> While costs vary, it\u2019s thought that a utility-scale turbine can cost between $1.3 million to $2.2 million per MW of capacity installed.\u00a0Typically, commercial turbines can cost about $4 million.<\/p>\n

3.\u00a0The average onshore turbine can potentially power 1,500 homes:<\/strong> Turbines with a capacity of 2.5\u20133 MW can produce more than 6 million kWh in a year. Offshore turbines can often produce twice the amount of electricity each year.<\/p>\n

2.<\/strong>\u00a0We could get a third of our energy from wind by 2050:<\/strong> Global wind power generation quadrupled between 2000 and 2006 alone. If growth levels keep up, then the wind will account for a third of global energy demands by the middle of the century.<\/p>\n

1.\u00a0There\u2019s big investment in wind energy:<\/strong> Denmark\u2019s Dong Energy is in the midst of building the world\u2019s largest offshore wind farm. It is building 300 turbines in the North Sea off the coast of England and is expecting to be able to power 1.8 million homes in the UK.<\/p>\n
