I have seen a high wind turbine.it rotates by wind and produce electricity. How electricity is produced by such a slow movement of wings?the dynmo which produce electricity must be rotated at high speed, how it works to produce electricity? secondly,when there is no wind, wouldn’t it stop electricity production??

Gears can be used to change the speed of the rotation, but it should be noted as well that electricity can be produced by slow rotation it just means a lower frequency.
> when there is no wind, wouldn’t it stop electricity production??
Yes. This is one of the major limitations of renewable energy sources, they tend to be unreliable. If the wind doesn’t blow there isn’t any wind power, if the sun isn’t shining there isn’t any solar power, etc. Power storage is a big challenge in making renewable energy viable.
