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 Energy
Wind is the flow of air or other gases that compose an atmosphere (including that of the planet Earth). On Earth and within other planetary atmospheres, wind consists of air molecules in motion. 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. Differences in density between two air masses lead to wind. Winds are commonly classified by their spatial scale, their speed, the types of forces that cause them, the geographic regions in which they occur, and their effect. While wind is often a standalone weather phenomenon, it can also occur as part of a storm system, most notably in a cyclone. While winds on Earth can be strong, the strongest winds within a planet in our solar system lie on Neptune and Saturn.
Winds are plotted on surface weather analyses indicating the direction the wind is blowing from as well as its strength, and over much of the globe wind speeds are measured over a ten-minute time frame, with the United States and India using different averaging intervals. Shorter duration winds, such as wind gusts, exceed the minimum value over the observed time frame and can cause substantial damage to power lines and suspension bridges. Winds with an intermediate duration, which sharply increase and last for a minute are termed squalls. Long-duration wind speeds have various names associated with their average strength, such as breeze, gale, storm, hurricane, and typhoon. Wind occurs on a range of scales, from local breezes generated by heating of land surfaces and lasting tens of minutes, to global winds resulting from the difference in absorption of solar energy between the climate zones on Earth. The two major driving factors of large scale atmospheric circulation are the differential heating between the equator and the poles, which causes the jet stream and the associated climatological mid-latitude westerlies, polar easterlies, and the trade winds, and the rotation of the planet (Coriolis effect), which causes the circular motion of air around areas of high and low pressure. Within the tropics, thermal low circulations over terrain and high plateaus can drive monsoon circulations. In areas where winds tend to be light, the sea breeze/land breeze cycle is the most important to the prevailing wind; in areas that have variable terrain, mountain and valley breezes dominate the wind pattern.
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 been used to steer sailing ships across vast oceans. By air, hot air balloons use the wind to take short trips. Airships have historically been used for longer trips, but nowadays are used for a variety of monitoring efforts such as during public sporting events and drug trafficking efforts. Wind can be dangerous, as areas of wind shear caused by various weather phenomena can lead to dangerous situations for airplanes. 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 large distances from their 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 due to their significant effects on those regions. Wind helps to spread wildfires. Nature uses wind to help disperse seeds from various plants, in order to enable the survival of those plant species, as well as flying insect populations. When combined with cold temperatures, wind has a negative impact on livestock. Wind impacts animal 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, such as electricity, using wind turbines. At the end of 2008, worldwide nameplate capacity of wind-powered generators was 121.2 gigawatts (GW).
Wind power produces about 1.5% of worldwide electricity use,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 typically connected to the local electric power transmission network; smaller turbines 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 (as with other forms of power generation) is not universally welcomed due to 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, and 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. Where wind is to be used for a moderate fraction of demand, additional costs for compensation of intermittency are considered to be modest.
Studies of a pan european power grid, show that wind can be used to meet eg 70% of load, over a wide area of interconnected grids, and then the costs of electricity delivered into the consuming country are comparable to present day power costs. http://www.claverton-energy.com/talk-by-dr-gregor-czisch-at-the-5th-claverton-energy-conference-house-of-commons-june-19th-2009.html
