Wind power cost levels should be studied in detail, since wind is the fuel for wind energy resources. Solar power, in a specialized format, is called wind. The surfaces of different parts of the earth are heated up by unequal amounts by the rays of the sun. This is caused due to multiple factors, including earth’s rotation, the uneven topographical features of the planet, and the absorption of varying amounts of heat at different levels of the earth’s atmosphere. As a result, certain parts of the world remain warmer than other regions.
As an example, the equator of the earth always remains much hotter than the cold poles of the earth, which remain snow-covered all round the year. A void gets created due to the movement in the upward direction of the warmer, lighter, less dense air. These empty spaces are quickly filled up by the heavier, cooler air that flow in from nearby regions. The process emanates a type of kinetic energy, and is itself termed as wind.
Modernized methods are made use of for converting this kinetic energy into wind energy. Wind power is defined as the process of generation of resources that can be used multiple number of times, like electricity.
Wind power cost amounts
For the purpose of generating electricity, wind power is currently the most widely used resource. Over the past couple of decades, the amount that was required to be spent on utility-grade units of wind energy has gone down greatly (by around 80 per cent). The wind power cost figures, which currently stand at 5 cents per kilowatt-hour, were once at a high of 30 cents per kilowatt-hour in the 1980s, when the wind power systems were first manufactured. Highly sophisticated technologies that are being used for producing electrical power have resulted in this enormous fall in the wind power cost levels.
Ideally chosen sites, totally upgraded methods, and the newer machines at the bigger wind power units have all contributed to the continuous fall in the overall cost of wind power. In fact, these techniques came into existence for attaining cost-cutting purposes.
There are several other economic advantages of using wind power systems, in addition to the cost-effective nature of the latter. These benefits combine to make sure that this source of energy would remain in demand over a long period of time in future too. Conventional power plants depend on the availability of fossil fuels for working properly.
However, fossil fuel supplies have become rather unpredictable in the present day world. On the other hand, the wind plants that generate power have a source of fuel that is natural, plentiful in supply and totally free of cost – wind itself. Complete faith can, hence, be put on the wind power plants. Resource planning, a crucial aspect of the process of generating power, and wind power units score over the conventional energy plants in this regard as well. The former do not have any negative impact on the earth’s environment, unlike the convention power generation units. The land area where a wind power system is installed can be rented by farmers too.
This feature gives the latter an ideal source for generating income over a long-run period. Income from two sources simultaneously is assured for the farmers, since the wind power systems take up only a little portion of the land leased for it, and farming can easily be carried on over the remaining parts of the land.
Choosing an ideal location for installing a wind power plant is, however, crucial for cost-effective performance of the latter. Places that have wind blowing at speeds at least equal to five or seven meters for second is deemed to be suitable for setting up these systems. A higher velocity of the wind raises the amount of output produced. Hence, an enough output of power can be obtained only if the wind power plant is set up on a suitable ground.
Cutting down on wind power costs
The cost figures associated with wind power can be easily reduced, provided wise and informed financial strategies are in place. Money needed to be spent on acquiring wind energy can be made to go down significantly, if this energy resource can be obtained in a similar way of financing as that of the gas power plants. Moreover, if a utility owns the wind power generating unit, a much lesser level of wind power cost results. For example, an output of wind power at the cost of 5 cents per kilowatt-hour can be obtained from an average 50 MW wind power plant. However, when the same plant is owned and financially managed by an IOU (investor-owned utility), power output costs can fall to around 3.5 cents per kilowatt-hour (which is about 30% lower than in the former case).
A cost-effective way to sustain earth’s environment
Visibility can be adversely affected, global warming gets a boost and acid rains might occur from the usage of the greenhouse gases that pollute the atmosphere. The wind power plants do not release any such environment-degrading gases, unlike the other conventional power units (like a coal plant). Thus, it is more advantageous to use the wind power units, in view of environmental sustenance as well. In fact, coal plants emit tiny particles of dust, which can result in many health hazards for human beings, including asthma, heart-related diseases and respiration problems – ultimately resulting in an increase in the overall rate of mortality. These risks are not associated with the usage of wind power plants.
In terms of costs too, the levels of wind power costs are way below that associated with coal power units. With its obvious eco-friendly nature, wind energy is steadily finding recognition all over the world. Wind power can be obtained totally free, does not cause any environmental degradation, and can be easily renewed as many times as required. Excess usage of power can also be cut down on by these systems. The cost of operating these plants is extremely low, so that only a nominal sum of money needs to be spent on them, particularly when compared to fossil fuel systems. There are no additional expenses required for buying the fuel (wind) either. Also to be kept in mind is that wind power generating plants would require a contract stretching over a long time period from the domains of power regeneration, since these plants have entered the markets comparatively recently. If that can indeed be done, the overall risk levels of the markets can be effectively slashed by lowering the costs of financing.
Individuals should consider setting up wind power systems at their home in right earnest. Such systems would be able to cut down on wind power cost amounts by reducing electricity consumption bills significantly. If you can get hold of a proper training and instruction manual, that would help you install a wind power plant all by yourself too. Such a manual would help you know where to put up the power plant for most efficient performance, what the required safety factors are, how the wiring systems are handled.
The availability issues of free batteries, and other components of these systems at relatively low prices, are discussed in such a guide. Read through this guide, and set up a wind power system in your home, easily and effectively.
