They are not very effecient. a wind turbine that is 50 % effecient is very effecient compared to other wind turbines. this is because most of the kinetic energy is changed into heat instead of electrical energy.
It is not really possible for wind turbines to convert 100% of energy into usable electricity. An efficiency level of 35 to 50% conversion is more realistic, since there are so many uncontrollable factors in wind energy - not least of which is the uncertainty of the weather!
Wind turnbines are a very efficient form of renewable energy. Wind trbines placed in the correct area can supply endless energy.
There is no point in wind turbines
The wind turbines collect the wind's kinetic energy.
Because more wind = more energy = more electricity generation per wind turbine = most cost efficient use of wind power.
because wind and wind turbines turn in to energy and to make electricity!
In any machine some energy is always lost as heat. In a wind turbine most of this will be created by friction between parts.

country side wind turbines and modern turbines

Because more wind = more energy = more electricity generation per wind turbine = most cost efficient use of wind power.
A wind turbines uses the wind to power an electricity generator.
Horizontal axis wind turbines, modern wind turbines, vertical axis turbines.
Wind energy is made by spinning turbines. The wind spins the wind turbines and they generate energy.

100134444 wind turbines are in michigan.

Kinda-sorta. Wind turbines rely on the wind, but what powers the wind is the sun.
Wind turbines can be up to 262 feet high.
