Energy from the windThe world today is run by energy. Scientists are constantly thinking of new ways to create energy. Creating energy may be the most valuable creation ever. Something that is even more valuable than energy is renewable energy. Renewable energy is any natural resource that can regenerate naturally over time, such as wood or solar energy; also called renewable energy, renewable energy resource, and renewable natural resource. The underlying principle of wind energy is the conversion of the kinetic energy of the wind into electrical energy. The source of energy is not just the wind. Uneven heating of the earth's surface by the sun with the pressure difference in the atmosphere creates the creation of wind. The devices used are wind turbines that are driven by the air pushing on the blades that turn the generator to allow the production of electricity. The power depends on the length of the turbine blades and the wind speed. The conversion rate is 45%. The windmill has been used since 500 AD. It was one of the first and most important instruments of power of the time. Wind energy has numerous advantages and disadvantages. In most things in life, a positive will usually be followed by a negative. Wind energy was first used by the Persians. They created the idea of ​​the windmill. Between the years from the sixteenth to the twentieth century AD, the vertical axis windmills were built. The Persians used these mills to grind grain, which was their most important crop at the time. Four hundred years later the English moved on to the Post Mills. The difference was that the windmill's axis was now horizontal, not vertical. It was used to grind grain and pump water. At the heart of the paper it is important that renewable resources are used. The positive aspects outweigh the negatives. From the environment to costs, renewable resources always seem better than fossil fuels. One day we will run out of fossil fuels and have to turn to renewable energy, but how about we learn as much as we can about wind energy, so when the time comes the wind will be used to its full potential.
