Definition and Technique of Production of Wind Energy and Description of the major wind energy conversion systems
Different factors related to the environment contribute to the production of wind energy, which, incidentally, is a type of solar power. The surface of Earth is not uniform, and hence is not equally warmed by sunrays. As such, certain areas become warmer than other regions. In these warmer parts, the air, which is lighter (with less density), moves upwards. This motion of the warm air results in the creation of a void. This space is soon occupied by cooler air from the nearby cold regions. Wind is the term used to describe this movement. Motion energy, or kinetic energy, is generated by these movements of air. Wind energy can be obtained by capturing and processing this kinetic energy, via mechanical methods. Wind energy turbines and wind mills are the two wind energy conversion units that are used in the present day.
Types of the conversion units
Wind energy conversion systems are commonly used to generate electricity and mechanical power by processing wind energy, as and when required. Among the two systems of conversion of wind energy named above, electricity is produced by energy turbines. Wind mills are used to create mechanical power. A study of the efficiency and cost effectiveness of these two conversion units is required. For that, we need a clear insight into the working mechanisms of these systems.
A simple process marks the way of functioning of wind turbines. Such a wind turbine typically has a rotor, to which two or three blades are attached. A main shaft is used, to which this rotor is now fixed. The shaft can spin a generator. The whole process results in the production of electricity. For effective production of electric power, wind turbines are generally set at raised levels, at a height of around 100 feet (or, thirty meters) from the ground surface. The velocity of wind flow is higher at such altitudes and is less roiling as well. Hence, a desirable amount of output can be obtained. On the other hand, the number of blades of a wind mill determines the efficiency with which the latter can produce mechanical energy. The amount of output generated also depends on the speed at which wind blows in a particular region. In terms of their functions, windmills are divided into different types, like tjaskers and wind pumps. A wind mill that has the capacity to pump out water from a well and/or a draining land is called a wind pump. Currently, these wind pumps are commonly used for providing drinking water to cattles. Human beings can also benefit from the water generated by these pumps. On the other hand, at places where the requirement is for a low head, drainage wind has to be used in order to obtain water. This function is performed by tjaskers. A comparative study of these two wind energy converting units is necessary to determine which among the two has a higher efficiency, and involves less spending of money as well.
Wind energy systems: Pros and Cons
Wind is a free and renewable source of energy. As such, the demand for wind energy is on a rapid upward spiral. Unlike the traditional power-producing plants or the greenhouse gases, wind is a pollution-free energy source as well, that does not, in any way, degrade the atmosphere. The gases that produce the greenhouse effects damage the cleanliness of the atmospheric levels. In addition, acid rains are often caused by natural gas, coal and other fossil fuels that are necessary for driving the conventional power producing plants. Chances of depletion of wind do not exist either, since the presence of sunrays itself guarantees the continuous availability of the former. Cost-effectiveness is another feature of wind power generators, since the latter take up a small part of the land area that are taken on lease by farmers. From these lease agreements themselves, the farmers can ensure a continuous annual flow of income. While setting up wind turbines, it has to be kept in mind that the ranches located in the rural regions are the best sites for availability of wind.
However, although the usage of wind energy plants holds out manifold advantages, there are certain disadvantages attached with these plants as well. Irregular availability of wind energy is the primary negative aspect of the former. Since wind flows are automatic, such flows might not be in keeping with what is required within a certain period by the wind energy units. Areas that are located far from posh regions serve as the best sites for wind. As such, places which need electric supply urgently might not be able to get it in many cases.
The present generation technicians are in favor of conserving and renewing sources of sources of energy. Hence, wind energy plants are becoming more and more popular, despite the fact that the latter has certain disadvantages.
Be it in the realm of finance or in terms of eco-friendliness, it makes practical sense to use wind energy. It is, in fact, impossible to turn a blind eye to the many favorable features of this energy source. Thus, it is highly advisable to set up a wind power unit at your home. A manual can come in extremely handy in guiding you in the process of its installation, and would also suggest the part of the house where the system should be set up, for maximum benefits. The places where batteries can be obtained for free and other parts of the system at relatively low rates, the process of completion its wiring, as also the recommended safety measures are also included in the manual. Thus, a manual is of great use when you start to install the wind energy conversion systems in your home.
