Windmill and Energy By Derek Yeung, Mark Tong, Henry Lai, Ernest Tse, Kenneth Chan

Wind The heat of the Sun The rotation of the Earth The Earth’s terrain. Caused by:

The power of wind, when harvested by wind turbines, can be transferred for producing energy. The power of wind, when harvested by wind turbines, can be transferred for producing energy. Wind

What is a Windmill? Noisy and may kill birds Cannot be used when there is no wind The bigger the propeller is the more energy it produces

Noisy and may kill birds Cannot be used when there is no wind The bigger the propeller is the more energy it produces What is a Windmill?

How to turn wind power into electric power? Wind Turbine turns the magnets in the generatorThe magnets creates electric currents and therefore causes the wires (the coil of the generator) around the magnets to have electricity voltage It is then set off with wires to other places for usage

Energy Transfer Happens where energy is transferred from one part to another by connections Wind (kinetic energy) TurbineTurbine GeneratorGenerator TransformerTransformer

Energy loss occur mostly when one type of energy was transferred to another type. It happens in windmills too. Energy Loss Wind (kinetic energy) 0% 0% Turbine (N/A depends on the direction of the wind) Turbine Generator4%Generator4% Transformer5%Transformer5%

Windmill Efficiency: Less than 90% Efficiency is the amount of energy that have not been losen in the process of producing energy.
