Wind Energy

The wind power is proportional to cube of the wind speed. The surface of the earth is not homogeneous. It absorbs the solar energy radiation differently which creates difference in atmospheric temperature. Thus the density and pressure of air also change which in turn move the air from one place to another. Therefore, the land and water along coast line, valleys and mountains create breezes. The wind power is proportional to cube of the wind speed. At present the harnessing of the wind energy is focused at highly potential wind sites where the average wind speed is high. New wind farms (MW range) are coming up in these areas from Multi-National Companies (MNC) because these sites are profitable and commercially viable. Thus the wind turbines are not installed and wind energy is not harnessed where the wind speed is low. However, in many undeveloped and even developing countries, there is no electrical power supply at all or there is no regular electrical power supply in vast areas. Substantial electric power may be generated using the accelerated wind. The impact factor of journal provides quantitative assessment tool for grading, evaluating, sorting and comparing journals of similar kind. It reflects the average number of citations to recent articles published in science and social science journals in a particular year or period, and is frequently used as a proxy for the relative importance of a journal within its field. It is first devised by Eugene Garfield, the founder of the Institute for Scientific Information. The impact factor of a journal is evaluated by dividing the number of current year citations to the source items published in that journal during the previous two years.
