Inside the wind turbine

Wind Tubine

Wind Power

wind power is the conversion of wind to useful energy by using wind turbines to make electrical power.

Wind farm

Wind farm consist of hundreds of wind turbines to generate Thousands of MW(Mega Watt) of electricity

Wind turbine

Wind turbine is to use the kinetic energy in the wind and convert it to Electrical energy which in turns help to reduce the reliance on fossil fuels.

Efficiency

Not all Blowing wind can be harvested as the mass of the blade, friction and drag cause it to slow down thus only about 59% of the kinetic energy of the wind is harvested

Types, Design & Construction of Wind Turbines

Horizontal-Axis Wind Turbine, HAWT, have the main rotor shaft and electrical generator at the top of the tower and must be pointed into the wind

Vertical-Axis Wind Turbine, VAWT, have the main rotor shaft arranged vertically one advantage of this is that it does not have to be pointed in the direction of the wind and can be at advantage when the wind direction is highly variable 

Solar energy

Solar energy

Solar Energy

Solar energy is to harness the radiant heat and light energy converting it to electricity

Solar energy is also  important and inexpensive

The international Energy Agency also said that this enhances sustainability, reduces pollution and keep fossil fuel at a low price and these advantages are global!

How does it work?

how does hydroelectricity work

CHANGE!

Hydroelectricity

Hydroelectricity is referring to generating electrical power through the use of flowing water, forcing water through a water turbine which is connected to a generator which produces electricity.

this is accountable for about 16% of global Electricity about 3427 TWh.

1. Stator

2. Rotor

3. Wicket Gate

4. Turbine Blade

5. Water Flow

 6. Turbine Generator Shaft

some countries that uses hydroelectricity is Three gorges dam(China), Guri Dam(VeneZuela).

Why Conserve Energy?

1. Social Responsibility

Everyone has a social responsibility to conserve energy for future generations to live in an environment that is equal or an even better environment than now

2. Financial benefit

Power bill is also currently the largest operating expenses of buildings in Singappore. Therefore with more efficient use of energy, you  will be able to save more in terms of operating cost.

What is Sustainable Energy?

sustainable energy is being able to supply energy and meet the needs of the present without compromising the needs of future generations.
Technology that promote sustainable energy include renewable energy sources such as Hydroelectricity, Solar Energry, Wind energy, etc.
