A gentle breeze cools the home on a hot summer day. A colorful kite floats high above the heads of a picnicking family at play. The tinkling of chimes beneath a baby's bedroom window lulls the infant to sleep. With sails unfurled, a sailboat races toward the horizon. The wind is friend. A hurricane roars inland, destroying homes and communities. Without warning, a thunderstorm rolls into town, dampening picnic plans. The slamming of shutters outside a baby's bedroom window shatters the infant's sleep. Surf's up, and the waves pound wickedly, whipping the sailboat toward the rocks. The wind is fierce. Enemy or ally? Friend or foe? Our relationship with the wind is often uncertain. Learn more about our fierce friend by exploring the science of wind energy. Blustery Beginnings Set the scene for studying wind. Begin by selecting background material. Present some of the motivational resources that are available. Gather resources from the bibliography of wind. Once everyone is thinking windy thoughts, move on to the next phase: inquiry-based activities for investigating wind. Investigating Wind Energy A series of four inquiry-based activities provides a framework for investigating the effects of wind and the energy of wind. The first activity offers open-ended exploration of wind's effects on objects. The next activities build on the early exploration, with students building windmill blades to demonstrate their notions of wind. Finally, kinetic energy becomes mechanical when students actually use their windmill to do work.

Credit: Warren Gretz Introduction to wind energy wind turbine Wind turbines, like windmills, are mounted on a tower to capture the most energy. At 100 feet (30 meters) or more aboveground, they can take advantage of the faster and less turbulent wind. Turbines catch the wind's energy with their propeller-like blades. Usually, two or three blades are mounted on a shaft to form a rotor. A blade acts much like an airplane wing. When the wind blows, a pocket of low-pressure air forms on the downwind side of the blade. The low-pressure air pocket then pulls the blade toward it, causing the rotor to turn. This is called lift. The force of the lift is actually much stronger than the wind's force against the front side of the blade, which is called drag. The combination of lift and drag causes the rotor to spin like a propeller, and the turning shaft spins a generator to make electricity. Wind turbines can be used as stand-alone applications, or they can be connected to a utility power grid or even combined with a photovoltaic (solar cell) system. For utility-scale sources of wind energy, a large number of wind turbines are usually built close together to form a wind plant . Several electricity providers today use wind plants to supply power to their customers. Stand-alone wind turbines are typically used for water pumping or communications. However, homeowners, farmers, and ranchers in windy areas can also use wind turbines as a way to cut their electric bills.

24. Nova Scotia Wind Energy Project (NSWEP) -- Overview Presents a one page invitation to join the project under the aegis of Dalhousie University. Each participating high school will be supplied with a small meteorological station with anemometer, wind vane, and temperature sensor. http://www.dal.ca/~nswep/

Welcome to the Home Page of the Nova Scotia Wind Energy Project (NSWEP) Introduction A growing body of scientific research indicates that the combustion of fossil fuels produces greenhouse gases, such as carbon dioxide, which are contributing to climate change. Many coastal regions, including almost all of Nova Scotia, will be particularly vulnerable to some of the predicted effects of climate change, notably sea-level rise and extreme weather events. A rise of less than a metre coupled with high tides and extreme weather events could severely disrupt the lives of many people living in low-lying communities along the Atlantic coast, the Bras d'Or Lakes and the Bay of Fundy. In December 1997, at the Third Conference of the Parties to the United Nations Framework Convention on Climate Change (UNFCCC) in Kyoto, Japan, the Canadian Federal government set a greenhouse gas target of 6% reduction relative to 1990 levels by the years 2008-2012. To help Canadians reach this target, the Federal government, in its 1998-99 budget, established the $150 million Climate Change Action Fund (CCAF). One of the objectives of CCAF is to provide Canadians with information on actions that they can take to reduce their greenhouse gas emissions.

27. Residential Wind Energy: Q&A Brief overview on purchasing and operation of a residential wind turbine. http://www.awea.org/faq/rsdntqa.html

State-by-State Info CONTENTS Will I save money? Turbine Sizing Who should buy a turbine? Environmental Benefits ... Where to Buy See the AWEA Publications Catalog for books and videos about small wind turbine applications. What do I need to know to purchase a residential wind turbine? How do residential wind turbines work? A wind turbine, which is installed on top of a tall tower, collects kinetic energy from the wind and converts it to electricity that is compatible with a home's electrical system. In a normal residential application, a home is served simultaneously by the wind turbine and a local utility. If the wind speeds are below cut-in speed (7-10 mph) there will be no output from the turbine and all of the needed power is purchased from the utility. As wind speeds increase, turbine output increases and the amount of power purchased from the utility is proportionately decreased. When the turbine produces more power than the house needs, the extra electricity is sold to the utility. All of this is done automatically. There are no batteries in a modern residential wind system. Small wind systems for remote applications operate somewhat differently.

28. Overview Of Wind Energy In California According to the Electric Power Research Institute, the cost of producing wind energy has decreased nearly four fold since 1980. wind energy Production. http://www.energy.ca.gov/wind/overview.html

Wind Energy in California In the year 2000, wind energy in California produced 3,604 million kilowatt-hours of electricity, about 1.27 percent of the state's total electricity . That's more than enough to light a city the size of San Francisco. More than 13,000 of California's wind turbines, or 95 percent of all of California's wind generating capacity and output, are located in three primary regions: Altamont Pass (east of San Francisco a portion of which is shown on the right in this photo from NREL ), Tehachapi (south east of Bakersfield) and San Gorgonio (near Palm Springs, east of Los Angeles). In 1995, these areas produced 30 percent of the entire world's wind-generated electricity. According to the Electric Power Research Institute , the cost of producing wind energy has decreased nearly four fold since 1980. The levelized cost of energy from wind turbines in 1993 was about 7.5 cents per kilowatt/hour. With current wind research and development efforts, the Energy Commission estimates that newer technologies can reduce the cost of wind energy to 3.5 cents per kilowatt/hour. Wind energy also creates jobs. The
