Wind energy is a type of renewable energy obtained from the wind, or in other words from the movement of air masses transferring from areas of high atmospheric pressure to nearby areas of lower atmospheric pressure, with speeds proportional to the pressure gradient. To take advantage of wind energy, machines called wind turbines or mills are used, activated by the movement of the wind as the propeller rotates. The propeller is in turn connected to a generator rotor that raises the speed of rotation to thousands of revolutions per minute, converting kinetic energy into electrical energy.
As we expand our awareness of and caring for the environment, we adopt behaviors that are likewise increasingly respectful of our environment. Following this trend, wind energy has been gaining credence as a clean and renewable alternative replacing other sources of energy based on fossil fuels, thus helping to reduce greenhouse gas emissions.
