6.12: Wind Energy

What types of energies does Wind energy convert?

It converts kinetic energy from the wind into mechanical energy that spins a turbine, which creates electricity.

How many homes can the average turbine power?

460 homes

What is the capacity factor of the average wind turbine?

15-30%

What can allow turbines to face wind?

Motorized drives with shafts

What are the two types of wind turbine locations?

Cluster Groups and Wind Farms in Bodies of water

Where are cluster groups usually located in?

In flat, open areas (rural)

What are the benefits of cluster group turbines?

Can share land with agriculture (no need for dedicated land), locating them for repair and maintainance is easier.

What are the benefits of offshore wind?

Capitalizes on faster wind speeds

What are the negatives of Offshore wind?

Requires transmission lines built across long distances to reach land

Benefits of Wind Energy

Non-depletable, No emissions, can share land uses, doesn’t destroy habitats

Cons of Wind Energy

It is not always available, can’t replace base-load power, can kill birds, can be considered ugly or loud
