Wind turbines change kinetic energy contained in the wind into mechanical energy; & this results in Mechanical Power for Generating an Electric Power.
There are no such thing as Wind Energy ; Wind Power; Wind Electricity. Wind is a source of Mechanical Power.
Electric Power Generation using a device called wind turbine is damaging to environment. Most of the damage happens during Engineering, Procurement, Fabrication, Manufacturing, Construction, Assembly, Installation, Commissioning, & Handover phases of wind turbine Electric Power Generating system.
Wind turbine blades fly off in storm. Renewable Energy No such thing Wind turbine waste of money & investment
Animals, wind and water. When civilization began, during the sixth millennium BC, the only available sources of power were animal: heavy tasks were performed by gangs of slaves, or by domestic animals. This division of labour was a prerequisite for the establishment of collective life.
The wind was the next source of power, at first used only for driving sailing vessels. Not until the tenth century AD, however, was the wind harnessed, by means of windmills, to mechanical tasks such as milling and sawing.
Water-wheels were invented earlier, probably in primitive form before the beginning of the Christian era. For centuries they remained man’s main source of mechanical power. But animals were slow and winds uncertain; water power was not always found in the right places. Particularly for mining, more concentrated, reliable and disposable sources of power were needed and urgently looked for throughout the Middle Ages.
The first is the bladed wheel. The earliest form was the water-wheel; later it appeared in the wind-mill, & finally as the steam or gas turbine or in the form of the rotary compressor.
A source of mechanical power must be reliable & flexible. It is for this reason that, though the winds are strong and cost nothing; we prefer to pay for fuel for our ships in order that they should “sail” with certainty, even when the wind is contrary or absent.
If you notice you will not see any of aircraft carriers being power by wind or solar panels. Do you know why? Because of poor availability; reliability; & maintainability as defined IEC 50 (191). So if wind & so called solar is not good enough for THEM. Why should they be good for schools, hospitals, factories, & homes!

Wind turbine production
The production of a device such as wind turbine requires inputs from all the production processes in the world &, through international trade.
For example, the foundation requires cement which has to be manufactured, produced & transported.
Foundation reinforcement bars requires fuel for steel production, & fuel for means of transporting steel bars to site.
The Turbine blades needs plastics as the raw material for the production of GRP as part of turbine blade, this consumes Oil as a feedstock & fuel for processing & manufacturing. Manufacturing of resin for the blade uses oil & the raw material is converted to resin using fuel. The resin is then transported for fabrication & manufacturing of blade wherever it might be in the world.
The above scenario repeats itself for every components in the 7 systems & sub-system in manufacturing & production of a wind turbine as shown in Table below:
