Wind energy is everywhere; we could use it more frequently

It is well known that the wind energy exists everywhere around us. But it is still difficult to use it for production of electricity. The yearly fluctuations in wind speed and direction are very difficult to track without special equipment. Small wind generators are ineffective and the focus is on huge wind turbines. Huge wind turbines are very expensive and the investments are huge. Therefore we should catch the wind. This means that we should employ the wind turbines when there is enough wind and store the electricity in batteries. Everyone can easily make a wind turbine at home from planks, car dynamo and accumulator. You still need an anemometers and a wind vane to measure the wind speed and direction. When the wind speed is high enough, your wind turbine is ready to use. You could become independent from the main power source.
