Advantages & Disadvantages of Wind Energy – Things You Should Know About

The Pros

Wind power (WE) has been developed in the past few years such that it is now cost competitive to other fuel resources (like natural gas) and it is the least expensive of all renewable energy sources. Because the fuel in the form of wind is free, wind power can offer a stable long-term cost for energy production. So is it amazing that wind power may be the quickest growing power generation business around the world?

We can help to meet the improving global power demand, and commitments from governments around the world to international agreements including the Kyoto Protocol (UNFCCC 1997) to eliminate the emission of greenhouse gases, as well as individual country commitments to mandatory renewable power goals.

Due to the appropriate service it has been claimed that it can provide approximately 28% of EU electrical energy by 2030. WE is also advantageous over traditional methods of creating power, in the sense that it is getting cheaper and cheaper to generate this kind of power as the technology matures, and mass production of the rotor blades becomes routine. Wind may soon be the most affordable way to generate power on a large scale, after all, it has come so far currently in such a short time, and there should be many more ways to optimize its efficiency not even dreamt of yet.

Wind energy is extremely rich in numerous parts of America. Wind sources are characterized by wind-power density classes , ranging from class 1 (the lowest) to class 7 (the highest). It is clean power. Unlike coal or natural gas, each kilowatt-hour of this type of power is free of charge of dangerous pollutants that contaminate our air and drinking water.

Unlike fossil fuel or natural gas, each kilowatt-hour is free of dangerous pollutants that contaminate our air and drinking water. Wind farms produce no air or drinking water pollution simply because no fuel is burned. It is in reality just a form of solar energy.

Using windmills is a very ancient ability, which may have even been developed in China before 1 AD, but the earliest written documentation comes from 1219. Cretans were reported to be using literally hundreds of sail-rotor windmills to pump water for crops and livestock. WE does not sterilize land from production. Farmers and ranchers can continue to work the area since the turbines use only tiny a fraction of the land area.

Wind energy plant owners make rent payments to the farmer or rancher for the use of the area, which supports the economy remote areas and offers job opportunities for local people. Farmers who own area that is suitable for wind harvesting could also take advantage of their location by setting up their own wind turbine or by leasing wind rights to a wind energy company.

Then techniques we use right now to harness the wind are still developing. This is not a perfect technology, but it holds powerful potential to diversify energy generation all over the world.

The Cons

Wind energy is not easily stored, and not all air currents can be harnessed to meet the timing of electrical energy demands. Good wind sites tend to be found in remote areas far from areas of electrical energy demand such as urban centers. This means that huge investment will be required in new energy distributions systems that will increase the cost tremendously, and mean many more unsightly energy lines marching across the area.

So, wind power is not necessarily the cure all it is offered to be. Due to the intermittent nature, industrial scale WE can produce an average of 10-21 % of the installed capacity (wind advocates claim 30%), requiring back up generation of 80-90%, which is usually going to have to be natural gas or fossil fuel.

Wind power is not a linear function of the speed of the wind. As an example, an increase in wind speed from 5 m/s to 6 m/s results in an increase in the yield of a turbine of not 20% but usually of 45%! But, once the wind rises too much no power at all is generated as the wind generator blades are furled for their own protection.

However, this power supply technique can be built on the small scale easily. Models can be found ranging from small size residential wind turbines creating about 10 kilowatt of energy to experimental behemoths that are more than 500 feet tall and produce 3 MW of energy, wind harnessing technology has many forms and purposes.

Terribly placed wind energy facilities have the potential to create major problems for wildlife, particularly for bird life. Turbines mounted on structures which were not designed as a turbine foundation commonly shake apart over time. Additionally, the vibrations translate into sound and can be unbearably noisy for those in the homes nearby. These are the main pros and cons of wind power.
