Acknowledgement
I would like to offer my sincere gratitude and appreciation to my mentor Ms.Olga Potapova Crighton for all the support and help through my final year for the completion of my honors project. Also, I would like to thank Mr.Mohamad- Al Musleh for his help in getting the required instruments on time for the completion of the project on time. I would like to thank my classmates, for their help and support through the year. Finally, my family, for the encouragement without which I wouldn’t have been able to complete the project.

Since the earth rotates, the wind goes in circular direction. This is called the Coriolis Effect. Named after Gaspard-Gustave Coriolis, the french scientist who discovered these wind patterns. This is also the reason for tornados and cyclones. Wind also causes erosion of land and the sand particles, changing the landscape every now and then. Wind, hence is one of the most important phenomena on earth’s surface.
Wind Energy is the most rapidly growing form of energy and the industry is undergoing a great boom since the last decade. At the rate we’ve been using up our non-renewable natural resources, an alternate to generate electricity is turning out to be a must. With the increase in wind-related industries such as wind farming and wind energy, the root of all this lays at the wind speed detection of the place in which they are to be installed.
Denmark leads the way in the production of Wind Energy producing a whopping 13.8 TW-h annually which contributes to 39% of the total energy used by them. United States of America, one of the largest economies in the world is aiming at depending on wind energy for 20% of their annual consumption of electricity by the year 2030. The above mentioned statistics speak highly of the potential of wind and its
Topic: Addiction to social media General Purpose: To persuade Specific purpose: To persuade my audience that social media is hurting us mentally and our social lives. Thesis: Social media can cause serious problems to you and your health, so we need to put addiction to social media to rest. I. Introduction A. Attention-getter: The ages of 55 and 64 year olds who use social media fell “worried or uncomfortable” when they can’t access any type of social media accounts (Wright, 2015).
A good estimate of the wind speed can be obtained by observing its effect on the water. For example, at 5 knots only small wavelets can be observed. A 10 knot wind speed will produce a few whitecaps. At 15 knots whitecaps can be seen up to 30% of the area. At 20 knots whitecaps can be seen up
Have you heard of Brian Scalabrine? If so, you may have heard of him by the name of “The White Mamba”. Do you know how many NBA teams he has played for? What number was he? There are many interesting facts including, His college career, NBA career, and his life now.
There is much controversy over whether or not minors should be tried and convicted as adults; most often with cases involving murder.

Determining where to build a wind farm is based on location. The most favorable locations are those that have a steady annual wind speed of 15.7-meter seconds or more.

Establish the durability of the wind-speed and position sensors on the wind turbine during abnormally high wind speeds, and methods of tackling problems such as icing or data resolution.
The average wind on the entire site is approximately 9m/s. Wind speeds of 7.5m/s are deemed economically viable. The wind speed can vary dramatically onsite. The wind speed was very low at 3m/s when we were there and we were told on our site visit that there have being wind speeds up to 50m/s experienced on the site. To prevent any damage the turbines cut out at a certain wind speed. This is typically 25m/s for the turbines on site.

Along most coastlines, land and sea breezes help to regulate temperatures throughout the year. In a system, if there is a temperature difference, heat moves from higher to lower. This concept can be seen as the foundation for the development of local winds. Christopherson and Birkeland (2015) elaborate on this idea: “The different heating characteristics of land and water surfaces create these breezes. Land gains heat energy and warms faster than the water offshore during the day…
Winds are caused by the irregular heating of the atmosphere by the sun, the variations of the earth's surface, and rotation of the earth. This wind flow, or kinetic energy, when "harvested" by modern wind turbines, can be used to generate electricity. There is an abundance of wind to meet our needs, “the potential of [the total] wind power [in the world] is. 20 times more than what the entire human population needs” (Maehlum). Currently, wind power is one of the lowest-priced renewable energy technologies available, costing between four and six cents per kilowatt-hour, depending upon the wind resource.
Abstract—this paper deals with testing of power and torque coefficient of savonius rotor using numerical analysis. Numerical analysis least costly quick time response so that it is better than experimental method. Due to poor aerodynamic coefficient of savonius rotor, many people perform analysis. Some factor like as TSR, overlapping condition, geometry of rotor etc. affects the coefficient. Numerical method is very effective for testing of rotor geometry for extracting more power from wind. Numerical analysis can be done as steady and transient analysis, where steady analysis in which time is steady and transient analysis time is varying. Using this flow of wind can be analyze complicated phenomenon of flow can be observed. Aim of this paper,
Thesis Statement: The world must continue to develop wind energy even though it cannot supply all electricity we need, because it is renewable, non-polluting, and convenient for people can use wind energy to produce their own supply. Wind is a form of solar energy. (“Wind Energy” n.d.) Wind are produced by the uneven flowing of heat, and the rotation of Earth.
The wind is an incredibly valuable renewable energy source and is in the forefront of renewable energy developments. It is used to convert wind energy into energy that can be harnessed and used via a variety of methods, including; wind turbines, windmills, sails and windpumps. For a renewable energy source, however, it is wind turbines that are used to generate electricity (see figure 1). Wind power has been used for this since the end of the nineteenth century, after Professor James Blyth of the Royal College of Science and Technology first attempted it (Boyle, 2012). However, It wasn’t until the 1980s that using wind power technology was sufficient enough to experience a rapid growth of the technology.
