COMPARING WIND POWER and
other RENEWABLE ENERGY SOURCES
This is

Dunno.
Just kidding.

Let’s compare this guy:

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.

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

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

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.

created from
farm crops, such

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…

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.

It can be harnessed by
using a drill…
Like this one?
Um… No, Jeff.

Earth to create a

WIND
So, yeah.

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!
