group 3 wind

Using wind turbines are very efficient and can generate a lot of electricity.
====The physics of a wind turbine involve lift and drag. Lift occurs when a low-pressure air pocket forms when the wind blows against the downside of a blade. This blowing of the wind against a blade is an example of drag. The force of lift is greater than that of drag. The spinning rotor spins a shaft, which in turn spins a generator to create electricity.====

Another efficient way to produce and store a large amount of energy from this is to build a cluster of turbines out on a piece of open land and create a wind farm.
====Large 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 produced by small domestic turbines. Wind energy, as an alternative to fossil fuels is plentiful, renewable, widely distributed, clean, and produces no green house gas emissions during operation.====
