He formed a committee consisting Otaste of green energy back in of panchayat members and advisers from 1996 when it installed solar street the government to advise on utilisation lighting. So when its ever-increasing of solar and wind energy on a large scale. population required bigger energy plans, The panchayat committee initially it could take the next step in 2006: invest planned to install a hybrid system of solar in a wind mill, even though this was not and wind energy because a government something panchayats are known to do. scheme provided 90 per cent subsidy to Odanthurai could do it because of the hybrid system. As the system was Odanthurai three reasons.

    Impact of windfarm OWEZ on the local macrobenthos community report OWEZ_R_261_T1_20090305 R. Daan, M. Mulder, M.J.N. Bergman Koninklijk Nederlands Instituut voor Zeeonderzoek (NIOZ) This project is carried out on behalf of NoordzeeWind, through a sub contract with Wageningen-Imares Contents Summary and conclusions 3 Introduction 5 Methods 6 Results boxcore 11 Results Triple-D dredge 13 Discussion 16 References 19 Tables 21 Figures 33 Appendix 1 44 Appendix 2 69 Appendix 3 72 Photo’s by Hendricus Kooi 2 Summary and conclusions In this report the results are presented of a study on possible short‐term effects of the construction of Offshore Windfarm Egmond aan Zee (OWEZ) on the composition of the local benthic fauna living in or on top of the sediment. The study is based on a benthic survey carried out in spring 2007, a few months after completion of the wind farm. During this survey the benthic fauna was sampled within the wind farm itself and in 6 reference areas lying north and south of it. Sampling took place mainly with a boxcorer, but there was also a limited programme with a Triple‐D dredge. The occurrence of possible effects was analyzed by comparing characteristics of the macrobenthos within the wind farm with those in the reference areas. A quantitative comparison of these characteristics with those observed during a baseline survey carried out 4 years before was hampered by a difference in sampling design and methodological differences. The conclusions of this study can be summarized as follows: 1. Based on the Bray‐Curtis index for percentage similarity there appeared to be great to very great similarity in the fauna composition of OWEZ and the majority of the reference areas.

  • Windmill Worksheet [From the NOVA Web Site]
    Windmill Worksheet [From the NOVA Web site] Teacher Notes Part of what students are doing in this activity is reverse engineering, in which students look at something that exists to figure out how it works rather than building from the ground up. On the Windmill Template (Figure A), the solid lines indicate where to cut the paper and the dot- ted lines indicate where to fold (but not crease) it. The circles indicate where to punch holes. Figure B shows how the corners of the windmill are folded over and attached to the straw and how the rubber bands are used to keep the windmill in place. Figure C shows the cup and string attachment, and Figure D shows how to hold the machine so that the straw spins freely as the windmill turns. Students will discover through trial and error how best to attach the string to the straw. Because there is no exact description of materials, student choices may vary. For example, one team may choose regular bond paper for the windmill while another may choose a card stock. This provides a good opportunity to discuss how different materials behave within the design and why. Students familiar with pinwheels will know that blowing on the windmill causes it to turn. Students may then use this information to help them understand how wheel-and-axle machines work. If students are not familiar with this type of simple machine, you may want to identify it at the activity's end. At the end of the activity, students may experiment by changing the size of the windmill, the type of paper used for the windmill, the diameter of the straw, or even substituting entirely new materials.

Copyright 2006 BJ Frey & PJ Hadden 2 Section 1.0 ABSTRACT Wind turbines are large industrial structures that create obtrusive environmental noise pollution when built too close to dwellings. This annotated review of evidence and research by experts considers the impact of industrial-scale wind turbines suffered by those living nearby. First, the paper includes the comments by some of the families affected by wind turbines, as well as coverage in news media internationally. The experiences described put a human face to the science of acoustics. Second, the paper reviews research articles within the field of acoustics concerning the acoustic properties of wind turbines and noise. The acoustic characteristics of wind turbines are complex and in combination produce acoustic radiation. Next, the paper reviews the health effects that may result from the acoustic radiation caused by wind turbines, as well as the health effects from noise, because the symptoms parallel one another.

  • Wind Power — Energy from Moving Air Wind Is Air in Motion
    Wind Power — Energy from Moving Air Wind is air in motion. It is produced by the uneven heating of the Earth’s surface by the sun. Since the Earth’s surface is made of various land and water formations, it absorbs the sun’s radiation unevenly. When the sun is shining during the day, the air over landmasses heats more quickly than the air over water. The warm air over the land expands and rises, and the heavier, cooler air over water moves in to take its place, creating local winds. At night, the winds are reversed because the air cools more rapidly over land than over water. Similarly, the large atmospheric winds that circle the earth are created because the surface air near the equator is warmed more by the sun than the air over the North and South Poles. Wind is called a renewable energy source because wind will be continually produced as long as the sun shines on the Earth. Today, wind energy is mainly used to generate electricity. The History of Wind Throughout history, people have harnessed the wind in many ways. More than 5,000 years ago, the ancient Egyptians used wind power to sail their ships on the Nile River. Later, people built windmills to run equipment and grind grain. The earliest known windmills, in Persia (Iran), looked like large paddle wheels. Centuries later, the people of Holland improved the basic design of the windmill. They gave it propeller-type blades made of fabric sails and invented ways for it to change direction so that it could continually face the wind.
