Wind Energy Guide
Wind Energy Guide - As fossil fuels become more expensive, it makes sense to look for alternatives. Wind Power is such an alternative. There are many ways to use wind and convert it into the energy you need.
Old wind mills have been in operation for many thousand years, and with today's technology and modern materials, wind has a lot of potential.

Wind is the flow of gases on a large scale. On Earth, wind consists of the bulk movement of air. In outer space, solar wind is the movement of gases or charged particles from the sun through space, while planetary wind is the outgassing of light chemical elements from a planet's atmosphere into space. Winds are commonly classified by their spatial scale, their speed, the types of forces that cause them, the regions in which they occur, and their effect. The strongest observed winds on a planet in our solar system occur on Neptune and Saturn.
In meteorology, winds are often referred to according to their strength, and the direction the wind is blowing from. Short bursts of high speed wind are termed gusts. Strong winds of intermediate duration (around one minute) are termed squalls. Long-duration winds have various names associated with their average strength, such as breeze, gale, storm, hurricane, and typhoon. Wind occurs on a range of scales, from thunderstorm flows lasting tens of minutes, to local breezes generated by heating of land surfaces and lasting a few hours, to global winds resulting from the difference in absorption of solar energy between the climate zones on Earth. The two main causes of large scale atmospheric circulation are the differential heating between the equator and the poles, and the rotation of the planet (Coriolis effect). Within the tropics, thermal low circulations over terrain and high plateaus can drive monsoon circulations. In coastal areas the sea breeze/land breeze cycle can define local winds; in areas that have variable terrain, mountain and valley breezes can dominate local winds.
In human civilization, wind has inspired mythology, influenced the events of history, expanded the range of transport and warfare, and provided a power source for mechanical work, electricity, and recreation. Wind has powered the voyages of sailing ships across Earth's oceans. Hot air balloons use the wind to take short trips, and powered flight uses it to increase lift and reduce fuel consumption. Areas of wind shear caused by various weather phenomena can lead to dangerous situations for aircraft. When winds become strong, trees and man-made structures are damaged or destroyed.
Winds can shape landforms, via a variety of aeolian processes such as the formation of fertile soils, such as loess, and by erosion. Dust from large deserts can be moved great distances from its source region by the prevailing winds; winds that are accelerated by rough topography and associated with dust outbreaks have been assigned regional names in various parts of the world because of their significant effects on those regions. Wind effects the spread of wildfires. Winds disperse seeds from various plants, enabling the survival and dispersal of those plant species, as well as flying insect populations. When combined with cold temperatures, wind has a negative impact on livestock. Wind affects animals' food stores, as well as their hunting and defensive strategies.
Windpower Workshop: Building Your Own Wind Turbine
Note that this book originates from Europe and may contain measurement units, etc. not commonly used in the US.
The Author, Hugh Piggott runs his own successful wind power business in Scotland. He advises individuals and companies in Britain and abroad on wind power turbines and systems. He has been teaching others how to build windmills for twenty years and has been featured as an advisor to the BBC television program, "Castaway."
Windpower Workshop: Building Your Own Wind Turbine
An Absolute Must-Have For Windmill Enthusiasts!
This book contains real practicality, not just empty theory. Talk about "put your money where your mouth is" - Hugh lives on a remote spit of land in Northern Scotland that doesn't even have roads, much less access to the power grid. If necessity is the mother of invention, there's good reason why he was highly motivated to develop the kinds of simple airfoils and low speed alternator combinations that produced real power. This rudimentary experience has taken him all over the world for installations and workshops. I guess having someone like that around makes him a pretty popular guy with his neighbors.
This book covers the theory necessary to understand wind energy basics, and proceeds as a how-to manual on shaping a simple turbine out of wood. It then shows how to build a low speed alternator out of a brake drum. (There is another book by Hugh called "Brake Drum Windmill Handbook" which goes into more detail).
The challenge is building an electrical generating system that operates at the slow rotational speeds of a wind turbine (e.g. 300 - 500 RPM). Everybody wants to hook up an automobile alternator, but even if it is optimized for high output at an idle, it probably will not start producing power until it reaches 1800 RPM. (Typically the engine/alternator pulleys have a ratio of 3 or 3.5 to 1 and the engine idles @ 600 RPM).
A great little book. -- Bruce Boatner (Eagle, Idaho USA)

Wind Power
Wind power is the conversion of wind energy into a useful form of energy, such as using wind turbines to make electricity, wind mills for mechanical power, wind pumps for pumping water or drainage, or sails to propel ships.
At the end of 2008, worldwide nameplate capacity of wind-powered generators was 121.2 gigawatts (GW)., which is about 1.5% of worldwide electricity usage;Wind Power Increase in 2008 Exceeds 10-year Average Growth Rate and is growing rapidly, having doubled in the three years between 2005 and 2008. Several countries have achieved relatively high levels of wind power penetration, such as 19% of stationary electricity production in Denmark, 11% in Spain and Portugal, and 7% in Germany and the Republic of Ireland in 2008. As of May 2009, eighty countries around the world are using wind power on a commercial basis.
Large-scale wind farms are connected to the electric power transmission network; smaller facilities are used to provide electricity to isolated locations. Utility companies increasingly buy back surplus electricity produced by small domestic turbines. Wind energy as a power source is attractive as an alternative to fossil fuels, because it is plentiful, renewable, widely distributed, clean, and produces no greenhouse gas emissions. However, the construction of wind farms is not universally welcomed because of their visual impact and other effects on the environment.
Wind power is non-dispatchable, meaning that for economic operation, all of the available output must be taken when it is available. Other resources, such as hydropower, and standard load management techniques must be used to match supply with demand. The intermittency of wind seldom creates problems when using wind power to supply a low proportion of total demand. http://www.claverton-energy.com/wind-energy-variability-new-reports.html
