Essay on The Importance of Wind Turbines for Renewable Energy

Chapter 1 Introduction 1.1 Motivation Recently, wind power has gained greater attention with respect to sources of renewable energy due to the maturity of the technology and its relative cost competitiveness. Wind power farms (WPFs) are scattered in remote areas (onshore and offshore) selected by the wind speed, water depth, and distance to shore. It is important to develop technology to monitor WPFs with higher capacities as the size and number of wind turbines in a WPF is continuously increasing. In order…

WIND POWER Wind is one type of renewable energy that can be developed to generate free and clean energy replacing the one that be renewed and cause the pollution such as fossil fuel. Wind energy can be extracted by using the suitable wind turbine that is suitable with the current wind speed at observe location which is eastern coast of peninsula Malaysia. Generally, Malaysia has a potential to use the wind as alternative energy because of the wind speed in Malaysia can reached until 12 m/s and…

Following the recent developments in renewable energy sources, wind turbines have been one of the primary devices focussed on. Basically, wind turbines are devices that convert the kinetic energy from the wind into electrical power for human usage. “Wind farms” are created in very windy places to harness this energy. It is however impossible to harness the entire power potential from the wind. Only 59% of the total kinetic energy of the wind flowing in the turbine can be harnessed. Efficiency greatly…

Therefore, similar to the rest of the types of power, wind is not nearly perfected to utilization. Besides the sight of windmills looks as if it is sticking out like a sore thumb, wind turbines cause animal deaths and noise pollution to plants. “Some news has been reported there are birds fatalities do to flying through the windmills” (www.awea.org). Imagine the sight when a pigeon flies through a rotating shaft made out of blades. Pretty disgusting; birds had it on them for using the bathroom…

Wind Power is the use of our natural wind that converts it into mechanical energy which eventually becomes electricity. You may not realize this, but we used wind power that dated centuries ago. It pumped water, ground grain, and plenty of other things. (Resources, awea.org) Ever since recorded history, people had the ability to use wind as a source of energy. Wind power was been used to propel boats along rivers as early as 5000 B.C. At 200 B.C., China used windmills to pump water, while in Persia…

costs, and the price of the gas itself (Pare). Wind energy costs 3.14 cents per kilowatt-hour this includes the capital costs and operating costs, but wind itself is free, so there is no cost for the source of energy (Pare). Based on the direct costs, wind energy is the same price as coal and cheaper than the cost of natural gas (Pare). If the indirect costs such as health and climate change are also incorporated into the total cost of the forms of energy, the price of natural gas rises to 8.09 cents…

This is because they can generate electricity in low wind speed. On the other hand, “vertical axes are suited well to the turbulent wind found in urban areas, and they don’t make a lot of noise while turning. But they require high wind speed wind to start rotation.”(Scottish executive, 2007) wind power 4 As we can see, many countries have used wind power to generate electricity, and the results that they have are very good. “By 2001, wind turbines around the globe were generating 30 terawatt-hours…

blissfully sedated by low conventional energy prices and are gulping down the few remaining years of cheap natural gas and Mid East oil. As we do this, the inertia of global warming is inexorably building. What drives the continued development of mechanical devices like wind turbines in the face of this widespread lack of support? In the case of wind turbine technology, I suspect that part of the reason for persistence of this vision is how accessible wind turbines are to the understanding. They are…

As a matter of fact in a direct-connected system, the wind turbine output is connected directly to the load. A turbine direct-connected control unit is used to provide the interface between the turbine and the load. As for battery system this charges the wind turbine after capturing energy in the battery bank, via a control unit. A controller is needed to ensure that the batteries are not over or under charged and can direct electrical power to another load for example space and/or water heating…

WIND TURBINE INTRODUCTION: Windmills are incredible creations that have its importance in our history. Early pioneers utilized windmills for pumping water out of the ground and provide the water for their cattle's over a century. Throughout the years, diverse outlines and varieties were made to make the windmill run more effectively. In spite of the fact that there have been many plans made, a large portion of the windmill parts still remained unaltered. Now-a-days the handling of “Electricity”…
