We continue our “Five things you did not know about ” series with another fascinating way of producing energy. Feel free to comment, give advice and share your personal opinions. So here they are, the five things you probably did not know about wind power.
1. 19% of the energy produced in Denmark is wind power. Unfortunately, Denmark is the only country that uses this much wind power. Worldwide the energy produced using the wind is only 1% of the total energy used.
2. It is believed that humans have been using wind power for at least five thousand years and that natural ventilation was a concept used by architects in building ancient structures.
3. Windmills have been first discovered in Afghanistan, in the 7′th century. They were made of six to twelve sails covered in cloth material and were used mainly for grinding corn.
4. In the present time, the most used form of producing wind power is a wind turbine. Wind turbines work by transforming the kinetic energy from the wind into mechanical energy which is then converted into usable electricity.
5. A wind farm (picture below) is basically an area filled with wind turbines. The largest wind farm in the world is the Horse Hollow Wind Energy Center in Texas. This wind farm has 421 wind turbines and can make enough electricity for 220,000 homes per year.
