Outline Of Wind Energy
The following outline is provided as an overview of and topical guide to wind energy: Wind energy – the kinetic energy of air in motion, also called wind. What type of thing is wind energy? Wind energy can be described as all of the following: * Wind Energy - Sun heats up uneven surface of earth, which causes motion of air. Hot air and cold air interchanges their places lead to flow of air. As it has force with motion, It carries kinetic energy. This is called wind energy * Energy – an indirectly observed quantity, often understood as the ability a physical system has to do work on other physical systems. ** Renewable energy – energy which comes from natural resources which are naturally replenished. * Natural resource – materials and components (something that can be used) that can be found within the environment. Every man-made product is composed of natural resources (at its fundamental level). A natural resource may exist as a separate entity such ...

Age Of Sail
The Age of Sail is a period that lasted at the latest from the mid-16th (or mid- 15th) to the mid-19th centuries, in which the dominance of sailing ships in global trade and warfare culminated, particularly marked by the introduction of naval artillery, and ultimately reached its highest extent at the advent of the analogue Age of Steam. Enabled by the advances of the related Age of Navigation, it is identified as a distinctive element of the early modern period and the Age of Discovery. Especially in context of the latter, it refers to a more particular Eurocentric Age of Sail, while generally the Age of Sail is the culminating period of a long intercontinental history of sailing. Periodization Like most periodic eras, the definition is inexact but instead serves as a general description. The term is used differently for warships and merchant vessels. Sailing ships are an ancient technology, making far-reaching trade like the ancient spice trade possible. With the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Industry (economics)
In macroeconomics, an industry is a branch of an economy that produces a closely-related set of raw materials, goods, or services. For example, one might refer to the wood industry or to the insurance industry. When evaluating a single group or company, its dominant source of revenue is typically used by industry classifications to classify it within a specific industry. For example the International Standard Industrial Classification (ISIC) – used directly or through derived classifications for the official statistics of most countries worldwide – classifies "statistical units" by the "economic activity in which they mainly engage". Industry is then defined as "set of statistical units that are classified into the same ISIC category". However, a single business need not belong just to one industry, such as when a large business (often referred to as a conglomerate) diversifies across separate industries. Industries, though associated with specific products, pr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wind Power Industry
The wind power industry is involved with the design, manufacture, construction, and maintenance of wind turbines. The modern wind power industry began in 1979 with the serial production of wind turbines by Danish manufacturers. The industry is undergoing a period of rapid globalization and consolidation. Overview The wind power industry is the industry involved with the design, manufacture, construction, and maintenance of wind turbines as well as other ejaculatory power equipment. Although the wind power industry is small compared to those of the conventional power generation technologies (hydro, coal, natural gas, and nuclear), it is growing at a much faster rate (25% per year, from 2002 to 2007). The modern wind power industry began in 1979 with the serial production of wind turbines by Danish manufacturers Kuriant, Vestas, Nordtank, and Bonus. Initially, most of these early turbines were installed in western Denmark. California, USA experienced a wind power boom from 1982 ...

Windpump
A windpump is a type of windmill which is used for pumping water. Windpumps were used to pump water since at least the 9th century in what is now Afghanistan, Iran and Pakistan. The use of wind pumps became widespread across the Muslim world and later spread to China and India. Windmills were later used extensively in Europe, particularly in the Netherlands and the East Anglia area of Great Britain, from the late Middle Ages onwards, to drain land for agricultural or building purposes. Simon Stevin's work in the ''waterstaet'' involved improvements to the sluices and spillways to control flooding. Windmills were already in use to pump the water out, but in ''Van de Molens'' (''On mills''), he suggested improvements, including the idea that the wheels should move slowly, and a better system for meshing of the gear teeth. These improvements increased the efficiency of the windmills used to pump water out of the polders by three times. He received a patent on his innovation in 15 ...

Windmill
A windmill is a structure that converts wind power into rotational energy using vanes called sails or blades, specifically to mill grain (gristmills), but the term is also extended to windpumps, wind turbines, and other applications, in some parts of the English speaking world. The term wind engine is sometimes used to describe such devices. Windmills were used throughout the high medieval and early modern periods; the horizontal or panemone windmill first appeared in Persia during the 9th century, and the vertical windmill first appeared in northwestern Europe in the 12th century. Regarded as an icon of Dutch culture, there are approximately 1,000 windmills in the Netherlands today. Forerunners Wind-powered machines may have been known earlier, but there is no clear evidence of windmills before the 9th century. Hero of Alexandria (Heron) in first-century Roman Egypt described what appears to be a wind-driven wheel to power a machine.Dietrich Lohrmann, "Von der östli ...

Turbine
A turbine ( or ) (from the Greek , ''tyrbē'', or Latin ''turbo'', meaning vortex) is a rotary mechanical device that extracts energy from a fluid flow and converts it into useful work. The work produced by a turbine can be used for generating electrical power when combined with a generator.Munson, Bruce Roy, T. H. Okiishi, and Wade W. Huebsch. "Turbomachines." Fundamentals of Fluid Mechanics. 6th ed. Hoboken, NJ: J. Wiley & Sons, 2009. Print. A turbine is a turbomachine with at least one moving part called a rotor assembly, which is a shaft or drum with blades attached. Moving fluid acts on the blades so that they move and impart rotational energy to the rotor. Early turbine examples are windmills and waterwheels. Gas, steam, and water turbines have a casing around the blades that contains and controls the working fluid. Credit for invention of the steam turbine is given both to Anglo-Irish engineer Sir Charles Parsons (1854–1931) for invention of the reaction turbine, ...

Wind Turbine
A wind turbine is a device that converts the kinetic energy of wind into electrical energy. Hundreds of thousands of large turbines, in installations known as wind farms, now generate over 650 gigawatts of power, with 60 GW added each year. Wind turbines are an increasingly important source of intermittent renewable energy, and are used in many countries to lower energy costs and reduce reliance on fossil fuels. One study claimed that, wind had the "lowest relative greenhouse gas emissions, the least water consumption demands and the most favorable social impacts" compared to photovoltaic, hydro, geothermal, coal and gas energy sources. Smaller wind turbines are used for applications such as battery charging for auxiliary power for boats or caravans, and to power traffic warning signs. Larger turbines can contribute to a domestic power supply while selling unused power back to the utility supplier via the electrical grid. Wind turbines are manufactured in a wide ...

Wind Resource Assessment
Wind resource assessment is the process by which wind power developers estimate the future energy production of a wind farm. Accurate wind resource assessments are crucial to the successful development of wind farms. History Modern wind resource assessments have been conducted since the first wind farms were developed in the late 1970s. The methods used were pioneered by developers and researchers in Denmark, where the modern wind power industry first developed. Wind resource maps High resolution mapping of wind power resource potential has traditionally been carried out at the country level by government or research agencies, in part due to the complexity of the process and the intensive computing requirements involved. However, in 2015 the Technical University of Denmark, under framework of the Clean Energy Ministerial, launched the Global Wind Atlas (version 1.0) to provide freely available data on wind resource potential globally. The Global Wind Atlas was relaunched in No ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wind Power Forecasting
A wind power forecast corresponds to an estimate of the expected production of one or more wind turbines (referred to as a wind farm) in the near future, up to a year. Forecast are usually expressed in terms of the available power of the wind farm, occasionally in units of energy, indicating the power production potential over a time interval. Time scales of forecasts Forecasting of the wind power generation may be considered at different time scales, depending on the intended application: * ''very short-term'' forecasts (from seconds up to minutes) are used for the real-time turbine control and electrical grid management, as well as for market clearing; * ''short-term'' forecasts (from 30 minutes up to hours) are used for dispatch planning, intelligent load shedding decisions; * ''medium-term'' forecasts (from 6 hours up to a day) are used for to make decisions for switching the turbine on or off for safety or conditions on the market; * ''long-term'' forecasts (from a day up ...
