Global Wind Day is annually celebrated on 15 June worldwide. It is organized by EWEA (European Wind Energy Association) and GWEC (Global Wind Energy Council). The purpose of this event is to discover wind energy and its power, possibilities of growth, it gives a chance to brainstorm ideas about how to reshape our existing energy systems, how to decarbonize our economies and to promote new job opportunities. The event also includes visit to wind farms, information campaigns, demonstration turbines being set up in cities, wind workshops and a wind parade.

What is Wind Energy?

 “Energy can be neither created nor destroyed, although it can be changed from one form into another.” - Newton’s Law of Conservation of Energy

Exactly like this,

“Wind Power is the conversion of wind energy into a useful form of energy.”

such as using:

  • Wind turbines to make electrical power,
  • Windmills for mechanical power,
  • Wind pumps for water pumping or drainage,
  • Sails to propel ships.

The electricity is generated when the wind passes through the blades of turbine. The wind’s kinetic energy is then captured by the blades through rotation and is converted into mechanical power. The blade’s rotation causes the internal shaft, which is connected to the gearbox, to turn 100 times quicker, producing electricity.

The Wind Energy is generated by onshore & offshore wind, where turbines are installed. Onshore wind farms can be located on land while offshore ones are installed in large water bodies.

Why Wind?

Wind is natural and in abundance. In comparison with fossil fuel energy, Wind Energy is cheaper, renewable, clean, produces no harmful gas emission, widely distributed while uses small area of land. Wind energy is now one of the most competitive energy sources in global market. For sustainable future Wind turbines have continued to become bigger, cheaper, better and more efficient.

In US, Wind Power accounts for about 8% of domestic energy. A Wind Turbine can generate up to 6million kWh of electricity per year, depending on environmental conditions and the size of turbine.

According to the report of GWEC below stats shows the installation of new wind power in 2020.

The Future Is In The Wind

Wind power, along with solar energy, would lead the way for the transformation of the global electricity sector. By 2050 about one-third (35%) of the total electricity needs will be full-filled by Wind Energy that is generated by onshore and offshore Wind Turbines. If that happens, more than a quarter of total emissions nearly 6.3gigatonnes of CO2 cuts by 2050 each year, that is surely a radical reduction of CO2 emission.

Researchers are continuously working to ameliorate turbine technology, such as extra efficient generators and more reliable blades to minimize energy and manufacturing costs and also by reshaping blade’s design and configuration to enhance robustness and rotational speed.

Followings are some currently developing Wind Energy Projects around the world:

  • Pakistan will install eight wind farms at the end of 2030 to generate enough electricity to cover the annual needs of up to 600,000 local households.
  • Saudi Arabia NEOM- The Line; will use abundant renewable energy for a sustainable future
  • US started 5 new wind energy projects in 2021.
  • Philippines 1st offshore wind farm.
