Renewable, clean, and universally accessible source of fuel used to produce energy
Wind TurbinesBenefits:
Costs Range From $1200-1800 (for personal use)
- pollution free
- costs drop as technology improves
2 Blades:
- Used in Solano, California and Oahu, Hawaii
3 Blades:
- Propels like a windmill
- considered most successful way
- Vanes
- emergency brakes
- active brakes for normal shut downs
- held close by electromagnets
3 blades & a tail:
- suited for remote areas and small power need
- simple form of a wind turbine
- tail turns to gather the greatest winds
- used in low wind speed areas such as Africa
Predictions -The protection of our natural resources is a growing concern of our future and in turn the use of renewable resources will be on the rise, as the efficiency of wind turbines are vastly improving.Function of turbines:
- use wind coming from all directions
- has large amounts of aerodynamic drag
- blades can be changed for area requirements
