Comparing Wind Power and Other Renewable Energy Sources

COMPARING WIND POWER and

other RENEWABLE ENERGY SOURCES

And see why many countries prefer wind

power to other renewable energy sources

ROUND 1

WIND

SOLAR

VS

Here’s one interesting fact:

Here’s one interesting fact:

Wind energy is actually a

form of solar energy.

Here’s one interesting fact:

Wind energy is actually a

form of solar energy.(uhuh)

Here’s one interesting fact:

Wind energy is actually a

form of solar energy.(uhuh)

That’s because winds are actually caused by the uneven heating of the atmosphere from

the sun.

This creates low-pressure and high-

pressure areas, which cause air to move.

Anyways,Everyone knows that the main energy source of every organism in the world is the

SUN.

It doesn’t mean it’s better for

power generation though.

The sun’s gone.

Solar panels don’t work at night.

Wind turbines, on the other hand, work whenever as long as there’s wind.

So these guys are still gonna work even

after the SUN comes down.

• Can generate electricity ANYTIME unlike solar panels which only work at daytime.• Nearly all countries have

a windy area. Few countries have continually sunny areas though.• Wind turbines look

cooler than solar panels. (I think)• Solar power costs nearly

twice more per KWh than wind power.

‘coz:

And the winner

is…WIND

ROUND 2

WIND

BIOMAS

S

VS

is a renewable energy resource taken from ‘recently alive’ plants.

BIOMASS

is a renewable energy resource taken from ‘recently alive’ plants.

BIOMASS

It’s usually

created from

farm crops, such

as corn

and soybean.

BIOMASS

It can be

used to

generate

different

forms of

energy,

such as

heat,

electricity

and fuel.

It’s usually

created from

farm crops, such

as corn

and soybean.

There’s one problem

though…

There’s one problem

though…Converting biomass to other

forms of energy involves

BURNING.

BURNING.

Which produces greenhouse gases in the process, such as

CO (carbon monoxide) and CO2 (carbon

dioxide), that contribute to global

warming.

On the other hand,

WIND TURBINES

WIND TURBINES have virtually

ZERO greenhouse gas emissions.

‘coz:

And the winner

is…• Does NOT produce

greenhouse gas emissions during conversion, unlike with biomass.• Can ‘pay off’ the

energy spent for its manufacture in 4-5 months of generation, whilst harvesting biomass crops often takes more energy than can be produced with it.

WIND

(again)

ROUND 3

WIND

HYDRO

VS

HYDROPOWER

Generates electricity through the use of falling water’s gravitational force.

HYDROPOWER

Generates electricity through the use of falling water’s gravitational force.

HYDROPOWER

It’s also the most widely-used renewable energy resource – having 777 GW of installed worldwide capacity (2006).

It also doesn’t produce a lot of greenhouse

gases during production.

It also doesn’t produce a lot of greenhouse

gases during production.(Just a little.)

Dams also have a variety of uses, such as flood control, making

hydropower development doubly useful.

WIND

TURBINES…

…on the other hand, look pretty cool.

Which could be another use for it:

WIND

TURBINES…

It also helps prevent global warming since

it does not emit any greenhouse

gases.

After months of

deliberation (and

sleepless sleepovers)…

‘coz:

The winner is…• Currently the most widely-

used renewable energy resource. Wind energy is catching up though, and it wouldn’t be long until it takes the top spot. Add the fact that it’s really hard to site a good location for a dam.• Incredibly efficient if sited

correctly. It’s also more reliable since water flow is almost always constant unlike wind, which is unpredictable.

HYDRO

(for now.)

ROUND 4

WIND

GEOTH

ERMAL

VS

GEOTHERMA

L ENERGY

GEOTHERMA

L ENERGY is heat energy stored inside the Earth.

GEOTHERMA

L ENERGY is heat energy stored inside the Earth.

It can be harnessed by

using a drill…

Like this one?

Um… No, Jeff.

Um… No, Jeff.(not his real name)

Somethin

g more

one.

Anyways,

Earth to create a

geothermal well.

WIND

So, yeah.

WINDOTHERS

31

Renewable Energy

Scoreboard

Wind was able to PWN all

the renewable energy

technologies except for

hydropower.

Wind Power’s renewable

energy market growth is

considerably higher than

Hydropower’s though.It wouldn’t be long (like, maybe 50 years?) before wind becomes the most widely-used renewable energy resource since

there are more feasible wind turbine locations than hydropower dam locations.

ANYWAYS,

FOR READING THE WHOLE PRESENTATION,

THANK

YOU!
