Why is wind power renewable?

 There are two types of power, renewable and non-renewable.  Wind is renewable because it will never stop blowing and it can replenish itself.  Unlike fossil fuels and coal, wind is renewable.  Why isn’t fossil fuels and coal renewable?  Well, once it is used up, it’s gone, it can’t   replenish itself.

Wind power in B.C

 B.C. has three wind farms, alone standing wind turbine, and a wind farm project.  The three wind farms are Bear Mountain Wind Park, Cape Scott wind farm, and Dokie ridge farm. The lone standing wind turbine is the eye of the wind, and the wind farm project is quality wind project.  B.C. has the fourth most wind capacity (mega-watts) among provinces and territories in Canada, after Ontario, Quebec, and Alberta. B.C. has 488.7 mega- watts of capacity.  B.C. even has its own wind turbine manufacturing company called “Endurance wind power.”                                                

How is wind power generated?

 Wind power is generated by wind turbines that convert the kinetic energy in the wind into mechanical power that people can use. The mechanical power can be used for different things, like grinding grain and pumping water, or a generator can make the power into electricity for people to use, and to power places like homes, schools, and businesses.

How is wind extracted from the air flow?

 A wind turbine is basically the opposite of an electric fan.  A fan uses electricity to make wind.  A wind turbine uses wind to make electricity.   The wind is extracted from the air flow by mainly the blades, rotor, and the low speed shaft.  When the wind blows, the blades lift and rotates when the wind is blown over them, and then the rotor starts to spin.
