The exploitation of wind energy has been growing worldwide, being one of the most noticeable renewable and sustainable energies. This has contributed for a global reduction of the fossil energy use, such as oil, known by its pollution and scarcity.
After our participation on WindEnergy Hamburg, the greatest tradeshow destined to wind energy, in which we promoted our full-range of wind turbine towers manufacturing support equipment, we’re going to reveal 15 facts about wind energy that you might didn’t know.
The conversion of wind in other forms of energy is produced since 2000 B.C..
The first windmills (identical to the ones in the follow image) emerged on the Persia and China. In addition, the sailors travelled in the ancient sailing boats using the wind force and the farmers used wind to bomb water and grind cereal grains in their windmills.
The first modern turbine was built on 1940 in Vermont, USA.
The turbine labored for 1100 hours until one of the blades started to fail. Until 1979, this was the biggest wind turbine ever built.
Wind turbine towers have been evolving over the years in terms of dimensions and wind energy production.
Comparing with today’s turbines, it is estimated that the blade diameter will double, and the electricity production will quadruple. Motofil already machined a 60m’s blade.

A 6000KW offshore turbine can generate energy to supply 5500 homes.
A small backyard turbine can provide energy to power a full home.
Wind energy is the only type of energy that doesn’t demand water use.
It is estimated that by 2030, approximately 30 trillion bottles of water have been spared in US, due to investments in wind energy.
The installation of a wind turbine is getting cheaper.
Its mass production and recent advances in technology are making the turbines cheaper, and their operational costs are minimum after the installation of the turbines. In addition, the exploitation of wind energy has been receiving subsidies and benefits from governments, because of its low pollution level.
Wind turbines can be installed in offshore locations, contrarily to most renewable energies.
These locations present great benefits given the fact of wind being more constant and stronger in the marine zones. In these locations the electric energy is transported to land by subaquatic cables.
Most modern wind turbines have three blades whose speed can achieve 320km/h.
(Similar to the average speed of a TGV – high-speed train).
1000KW of electricity from wind energy offset the production of approximately 2600 tons of CO2
(According to National Renewable Energy Laboratory (NREL)).
On December 2017, China was the biggest wind energy producer in the world, corresponding to a 1/3 of the global production.

China is also the world leader in terms of the number of wind turbines. Approximately 105 thousand of the 340 thousand in the world in 2016, i.e. 1/3, were Chinese.
1,155,000 is the number of employees by the wind energy industry in the world.
It is estimated that by 2020, in the European Union, there will be 520 thousand employees in this sector.
In 2016 Denmark was the European leader in terms of electric energy production from wind energy sources – about 40%.
Portugal occupies the 4th position with approximately 20%. More info here.
The most significant drawbacks respecting wind energy are the changes in the wind speed and the fact that this energy type is not applicable to all areas.
The visual impact, the noise and the possible occupation of fertile agricultural land are considered as being disturbance factors. On the other hand, the advantages overlap the unfavorable factors.
The highest turbine in the world is a Vestas of 8000KW, whose blade’s diameter is of 164m.
Currently, the highest blade is a LM Wind Power of 88.4m.
The wind energy continues to be under-used, nevertheless its sustainability potential for the future.
In the last decade there was a 25% increase of production of energy from wind turbines, however, this renewable energy still corresponds to a small percentage of the world’s energy consumption (3.7% in 2015).
One of Motofil’s purposes in terms of social responsibility is to contribute for the development of solutions that promote the global sustainability. Particularly, in which respects to wind energy sector, it has been a great challenge to Motofil, to ensure turn-key automated technologies, that meet the productive needs of this sector.
