Practicality of Wind Energy
Energy where does it come from, how do we get it, we all have heard the old saying that energy cannot be created nor destroyed. The whole universe has all of this useful energy just floating around in it but how do we harness it, to put it to use for our benefit. Over the years engineers have come up with many different ways to harness this energy and use it to do work. In order to get energy we have to take earths recourses and use them to harness it. These resources, are known as renewable and non-renewable energy. Non-renewable energy sources are fossil fuels: coal, petroleum, and natural gas. They formed many years ago back when the earth was just a swamp land covered in moss and wet vegetation. Back when the

For thousands of years farmers have dug wells to use the wind for mechanical force to pump water for livestock. This all changed in the 80s, scintest came up with a better way for the wind mill to run, instead of using a wind mill to produce mechanical force. Why not use it to create electricity. To that day instead of being called a wind mill it was transformed into a wind turbine. Today the world is starting to realize that wind power is a clean promising new energy source which can serve as an alternative to fossil fuels. Wind energy turbines can be used as stand-alone applications connected to a utility power grid. For utility-scale sources of wind energy, turbines are usually built close together to form a wind farm that provides bulk power. Several electricity providers use wind farms to supply power to their …show more content…
First of all the turbine blades. The blades are about the same thing you can fined on the front end of an airplane. They are designed to capture as much wind as possible to keep them turning. Even with not much wind they will still be able to turn because of their sleek design. The hub of the turbine is rotated as the blades generate lift from the passing wind. The rotational movement of the hub is transferred by a shaft into the nacelle which hoses a generator, when turned creates good clean electricity. Generators come in two types fixed speed and variable speed. Fixed speed generators can only run at a constant speed, and the electricity that is produced is what you get. The good thing about the fixed speed generators the power they produce can be put right into circulation. Variable speed generators produce electricity at a varying frequency. So however fast the turbine spines is how fast the generator spins. The variable speed generators can produce more power one day and less the next. The bad thing about them is the power they create has to be corrected otherwise it would send surges down the power lines. The generator that sits inside the nacelle is very heavy and has to sit high in the air to be able to grab enough wind. The tower is a relatively simple component, constructed of heavy foraged steel to be able to support all of the weight. The tower is white and stands 150
