Advantages of Wind Power

The wind power industry is a growing market that is set to expand exponentially in the next few years. As the energy crisis develops and fossil fuels are depleted, more people are turning to alternative energy sources to solve their personal energy needs. All across the world residences, businesses, and even nations are turning to wind power to help bridge the supply and demand gap. The advantages of wind power are absolutely numerous and varied.

Many of the most convincing advantages of wind power are more directed toward residential wind turbine owners. For example, one of the major advantages of wind power is that it is highly economical. Owners of wind turbines can expect to see a savings between fifty and ninety percent on their utility bills. In some cases, owners and builders of wind turbines will even see a profit. Wind turbines built in prime locations can actually generate more energy than is needed to fuel a particular home. In these cases, the local utility company will automatically purchase the excess energy.

Homeowners interested in wind turbines will find it particularly advantageous to learn that a wind turbine system occupies very little land. Since the turbine is constructed on a tall tower and the generation system is within the tower, the land below can continue to be use. This is especially important for farming and agricultural areas. The builder can continue to use and profit from the land below. Another one of the advantages of wind power is that it can power residences that are remote, and are not connected to the electric power grids. These areas can install their own wind turbine systems and use the local wind energy to generate the energy needed for the area.

There are also many advantages of wind power that affect the world at large. For example, wind energy is completely renewable. Unlike fossil fuel based energy sources, the people of the world will not have to worry about whether or not this energy source will run dry. By nature, it will not. Wind energy is also a zero emissions energy source. Wind turbines produce no greenhouse gases or other pollutants. In fact, wind turbines can offset emissions. Over the typical lifetime of a residential wind turbine, the turbine will have displaced several tons of greenhouse gases. Another advantage is that wind turbines have the potential to help developing countries. Countries with areas without modern connectivity may greatly benefit from the highly renewable and extremely cost efficient energy system.

With the rise of wind power, many people are starting to investigate and inquire about this energy source. The advantages of wind power are numerous and varied. From appeals to residential owners to great advantages for nations and the world, the use of wind power should appeal to everyone.

Your Questions About Wind Turbine Generators Types

Sharon asks…

What is the dollar cost of a megawatt wind turbine?

The megawatt size wind turbine seems to be a standard so why not have the cost of these machines available to compare with other type of electric generators?

admin answers:

In terms of the initial cost, just to purchase a commercial scale turbine, the usual price is roughly $1 million per megawatt of capacity. So, a GE 1.5 MW would cost around $1.5 million. Installation and development of the site would be additional costs.

Robert asks…

What type of bearings to use in a savonius wind turbine?

Hi all

I am currently building a savonius wind turbine that will be around half a meter tall. I have the general plan drawn up but just need some answers on what type of bearing to use – I really have no idea about different bearings/lubricants/size restraints etc. Would really appreciate any help that could be provided.

Thanks!

admin answers:

Basically you need a thrust bearing somewhere in the process to take the weight and another one or two bearings to take the wind force and keep it upright. If you are mounting above a generator, there might be a thrust bearing in the generator.
In your design, you have to provide for mounting the bearings. Lets suppose you were putting the unit on a shaft with a pulley on the bottom to drive a pump or generator off to the side via a belt. You would go to www.grainger com or local bearing firm and tell them you wanted a flat mount ball bearing for your shaft diameter – this would be the top support – and you wanted a flat mount thrust bearing for the bottom, as well as a shaft collar all to match the shaft. For your project these might total $15-20.
The simplest possible mount would be a stiff frame rectangle to which you mount the ball bearing in the middle of the top and the thrust bearing at the bottom. What the shaft collar does is screw to the shaft and rest against the bearing, transferring the weight. Since I have proposed a pulley, the shaft would have to be long enough to go through the frame to put the pulley below, so you didn’t have to take the unit apart to change the belt.
To be honest, most ball bearings even if not thrust, will take much more weight than your turbine and you could probably get the shaft collar and two bearings at your hardware store or home center where they are sold as replacements for wheel barrow and cart wheels
