No, unless fossil fuel energy is used in their construction. In that case, wind turbines generate the amount energy required to make them within 6-12 months. That's the fastest of any type of energy - It takes a fossil fuel turbine about 2 years to generate the same amount of energy involved with it's construction.
Wind systems also consume fossil fuels when the wind is above the safe operation limit by placing power on the generators to prevent the blades from turning. They also consume power for a few minutes while starting to get the blades to the correct speed and sync with the grid. Despite these consumptions, wind is still a net provider of energy and they generate much more than they consume.
it takes about 10 turbines for 1 fossil fuel to work.
No. Wind turbines capture the wind's energy and convert it into electricity.

Wind energy is not better than water energy. They are both very similar in that they are: * free (after the initial cost of the turbines) * sustainable (they won't run out) * renewable (they are still there tomorrow even if we use them completely today) If there is no wind, then the wind turbines don't turn to provide electricity. This can happen quite often, unless the turbines are placed where the wind blows non-stop all year round. If there is no water, then the water turbines don't turn. This will happen only rarely if the turbines are placed in the best position. Using ocean waves and tides will be more reliable than rivers which can dry up in droughts.
it will mean that there will be more fossil fuels to burn in the future and then the normal electricity to use x
yes wind is a renewable source of energy and that is what turbines use
Wind power is a free resource. The use of the turbiine is becoming more and more popular, especially with large production companies as they are paying out, often with government grants attached for these turbines and using the power they create for running their business. Whilst some are not fully covering the megawatt demand, they are reducing the demand on fossil fuel based power generators.
So far there are no known reasons to use radioactive substances in wind turbines.
If you mean energy then you use wind turbines
energy water
you could use wind turbines on wind farms
Wind Turbines are very convenient and they are very recommended. Wind turbines can dramatically decrease your use of electricity and thus decrease your electric bill.
