Wind Energy
Wind is an important form of energy because it is clean, safe, and renewable.We decided to try to make a windmill make the teeter totter spin because it would help save he environment by reducing the amount of Co2 in the air, since we are using wind power, not gas. Scientists and different manufacturers are starting to make different types of green equipment. We now have solar powered devices small enough to run a laptop computer and large enough to power entire office buildings. Solar and wind powered jets have soared through the sky at incredible heights and speeds, all while leaving every drop of oil and gas on the ground. But even though we have new devices which create energy in many different ways, some have stayed the exact same for many years.
A wind turbine is a very simple piece of equipment. It is a machine that converts the kinetic energy in wind into mechanical energy . If the mechanical energy is used directly by machinery, then the device is referred to as simple a windmill. But if the mechanical energy is then converted to electricity, the machine is called a wind turbine. Wind machines have been around since 200 B.C., when Persians used them for grinding grain. They then moved to Romans, to the Dutch, and ultimately to Cleveland, Ohio where the first windmill was used to produce electricity.
