Renewable Energy Exam Questions with Complete Solutions Latest Update Graded A+
Rotor - Answers Bolted to the main shaft and consists of three blades that catch the wind and turn
Gearbox - Answers Converts 22 rpm from the rotor to 1500 rpm needed for the generator
Generator - Answers Makes electricity when it turns, sending the current down the tower in the cables
Yaw Motor - Answers Turns the nacelle so the rotor faces the wind
Anemometer - Answers Measures wind spend and sends that information to the control tower
Mechanical Brake - Answers Makes sure the rotor will not start turning while it is being repaired or
serviced
Main Shaft - Answers Connects the rotor to the gearbox
Yaw Bearing - Answers Track which turns the nacelle and rotor into the wind
Radiator - Answers Cools the water in order to cool the generator
Controller - Answers Computer which controls the parts of the wind turbine
Wind Vane - Answers Measure the wind direction so that the nacelle and rotor can be turned properly
Small Shaft - Answers Connects the gearbox to the generator; turns very fast
Renewable Resource - Answers Resource that can be replenished by a natural process in a human's
lifetime
Nonrenewable Resource - Answers A resource that cannot be replenished at a scale comparable to its
consumption
Top of a hill - Answers The best place to place a wind turbine
Tower - Answers Made from tubular steel and supports the structure of the wind turbine
Nacelle - Answers Houses all of the parts of the wind turbine and turns so that the rotor is facing the
wind.
Transformer - Answers Takes energy from the generator and distributes it to homes, businesses, etc.
Foundation - Answers Concrete setting beneath the tower of the wind turbine which secures it in place
