What is Wind Power?

Wind is caused by huge convection currents in theEarth's atmosphere, driven by heat energy from theSun. This means as long as the sun shines, there will

be wind.The moving air (wind has huge amountsof "inetic energy, and this can be transferred intoelectrical energy using wind turbines. The wind turns

the blades, which spin a shaft, which connects to agenerator and ma"es electricity. The electricity issent through transmission and distribution lines to asubstation, then on to homes, business and schools.

Wind turbines cannot wor" if there is no wind,or if the wind speed is so high it would damagethem.

Wind turbines are usually sited on high hills andmountain ridges to ta"e advantage of theprevailing winds.

#ust li"e a windmill, wind energy turbines havebeen around for over $%%% years. &rom oldolland to farms in the nited States, windmillshave been used for pumping water or grindinggrain.

Types of Wind Turbines

1. HAWT (Horizontal Axis WindTurbines)

the common style that most of usthin" of when we thin" of a windturbine. * *WT has a similar designto a windmill, it has blades that loo"

li"e a propeller that spin on thehori+ontal ais.

Types of Wind Turbines

2. VAWT (Vertial Axis Wind Turbines) have the main rotor shaft arranged

vertically. The main advantage of thisarrangement is that the wind turbine does

not need to be pointed into the wind. This isan advantage on sites where the winddirection is highly variable or has turbulentwinds.

With a vertical ais, the generator and otherprimary components can be placed near theground, so the tower does not need tosupport it, also ma"es maintenance easier.

Did you know...The largest wind turbine in the world, located in Hawaii,stands 20 stories tall and has blades the length of afootball eld.

An average wind speed of 14 iles per hour is needed

toconvert wind energ! into electricit!. "ne wind turbine can produce enough electricit! to

power up to #00 hoes.

The rst power$generating turbine was constructed in

"hio during the late 1%00&s and was used to chargebatteries.

'ind energ! is the fastest growing segent of allrenewable energ! sources.

1.2nce the wind turbine is built the energy it producesdoes not cause green house gases or other pollutants.

2.*lthough wind turbines can be very tall each ta"es up

only a small plot of land. This means that the land belowcan still be used. This is especially the case inagricultural areas as farming can still continue.

1.The strength of the wind is not constant and itvaries from +ero to storm force. This means that windturbines do not produce the same amount ofelectricity all the time. There will be times when theyproduce no electricity at all.

2.Wind turbines are noisy. Each one can generate thesame level of noise as a family car travelling at =%mph.

Biomass

the energy which is contained inside plants andanimals.

This can include organic matter of all "inds; plants,animals, or waste products from organic sources.

These sorts of energy sources are "nown as biofuelsand typically include wood chips, rotted trees,manure, sewage, mulch, and tree components./hlorophyll present in plants absorbs carbon dioide

from the atmosphere and water from the groundthrough the process of photosynthesis. The sameenergy is passed to animals when they eat them.

Biomass

4t is considered to be as renewablesource of energy because carbondioide and water contained inside

plants and animals are released bac"in to the atmosphere when they areburned and we can grow more plants

and crops to create biomass energy.

How is biomass on#erted into ener$%?Burnin$&This is a very common way of converting organic matterinto energy. 1urning stu3 li"e wood, waste and other plantmatter releases stored chemical energy in the form of heat,

which can be used to turn shafts to produce electricity. >et'ssee this simple illustration of how biomass is used togenerate electricity.


26/38

1. Energy from the sun is transferred and stored inplants. When the plants are cut or die, woodchips, straw and other plant matter is delivered tothe bun"er

2.This is burned to heat water in a boiler torelease heat energy (steam.
