HELP.<br />This is EARTH.<br />She’s kinda HOT.<br />

6.
WHAT CAN WE DO?<br />

8.
Dunno.<br />

9.
Just kidding.<br />

From these 5,<br />WIND<br />

20.
From these 5,<br />WIND<br />is the fastest-growing renewable energy source.<br />

21.
From these 5,<br />WIND<br />is the fastest-growing renewable energy source.<br />(for good reasons)<br />

22.
WIND<br />Let’s compare this guy:<br />

23.
WIND<br />Let’s compare this guy:<br />with these other guys:<br />HYDRO<br />BIOMASS<br />GEOTHERMAL<br />SOLAR<br />

24.
And see why many countries prefer wind<br />power to other renewable energy sources<br />

ROUND 1<br />V<br />S<br />SOLAR<br />WIND<br />

26.
Here’s one interesting fact:<br />

27.
Here’s one interesting fact:<br />Wind energy is actually a form of solar energy.<br />

28.
Here’s one interesting fact:<br />Wind energy is actually a form of solar energy.<br />(uhuh)<br />

29.
That’s because winds are actually caused by the uneven heating of the atmosphere from the sun. <br />This creates low-pressure and high-pressure areas, which cause air to move.<br />Here’s one interesting fact:<br />Wind energy is actually a form of solar energy.<br />(uhuh)<br />

30.
Anyways,<br />Everyone knows that the main energy source of every organism in the world is the<br />SUN.<br />

31.
It doesn’t mean it’s better for power generation though.<br />

32.

33.

34.
The sun’s gone.<br />

35.
Solar panels don’t work at night.<br />

36.
Wind turbines, on the other hand, work whenever as long as there’s wind.<br />

37.
Wind turbines, on the other hand, work whenever as long as there’s wind.<br />

38.
Wind turbines, on the other hand, work whenever as long as there’s wind.<br />So these guys are still gonna work even after the SUN comes down.<br />

39.
Wind turbines, on the other hand, work whenever as long as there’s wind.<br />So these guys are still gonna work even after the SUN comes down.<br />

40.
And the winner is…<br />WIND<br />‘coz:<br /><ul><li>Can generate electricity ANYTIME unlike solar panels which only work at daytime.

41.
Nearly all countries have a windy area. Few countries have continually sunny areas though.

42.
Wind turbines look cooler than solar panels. (I think)

43.
Solar power costs nearly twice more per KWh than wind power.</li></li></ul><li>ROUND 2<br />V<br />S<br />BIOMASS<br />WIND<br />

44.

45.
BIOMASS<br />is a renewable energy resource taken from ‘recently alive’ plants.<br />

46.
It’s usually created from <br />farm crops, such as corn <br />and soybean.<br />BIOMASS<br />is a renewable energy resource taken from ‘recently alive’ plants.<br />

47.
It can be used to generate different forms of energy, such as heat, electricity and fuel.<br />It’s usually created from <br />farm crops, such as corn <br />and soybean.<br />BIOMASS<br />is a renewable energy resource taken from ‘recently alive’ plants.<br />

48.
There’s one problem though…<br />

49.
Converting biomass to other forms of energy involves<br />There’s one problem though…<br />

50.
BURNING.<br />

51.
BURNING.<br />Which produces greenhouse gases in the process, such as CO (carbon monoxide) and CO2 (carbon dioxide), that contribute to global warming.<br />

52.
On the other hand,<br />

53.
WIND TURBINES<br />

54.
WIND TURBINES<br /> have virtually ZERO greenhouse gas emissions.<br />

55.
(again)<br />And the winner is…<br />WIND<br />‘coz:<br /><ul><li>Does NOT produce greenhouse gas emissions during conversion, unlike with biomass.

56.
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.</li></li></ul><li>ROUND 3<br />V<br />S<br />HYDRO<br />WIND<br />

57.
HYDROPOWER<br />

58.
HYDROPOWER<br />Generates electricity through the use of falling water’s gravitational force.<br />

59.
HYDROPOWER<br />Generates electricity through the use of falling water’s gravitational force.<br />It’s also the most widely-used renewable energy resource – having 777 GW of installed worldwide capacity (2006).<br />

60.
It also doesn’t produce a lot of greenhouse gases during production.<br />

61.
It also doesn’t produce a lot of greenhouse gases during production.<br />(Just a little.)<br />

62.
It also doesn’t produce a lot of greenhouse gases during production.<br />(Just a little.)<br />Dams also have a variety of uses, such as flood control, making hydropower development doubly useful.<br />

63.
WIND TURBINES…<br />

64.
WIND TURBINES…<br />…on the other hand, look pretty cool. <br />Which could be another use for it:<br />

65.
WIND TURBINES…<br />…on the other hand, look pretty cool. <br />Which could be another use for it:<br />Terrain Decorations. <br />

66.
WIND TURBINES…<br />It also helps prevent global warming since it does not emit <br />any greenhouse gases.<br />

67.
After months of deliberation (and sleepless sleepovers)…<br />

68.
(for now.)<br />The winner is…<br />HYDRO<br />‘coz:<br /><ul><li>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.

69.
Incredibly efficient if sited correctly. It’s also more reliable since water flow is almost always constant unlike wind, which is unpredictable.</li></li></ul><li>ROUND 4<br />V<br />S<br />GEOTHERMAL<br />WIND<br />

GEOTHERMAL ENERGY<br />

72.
GEOTHERMAL ENERGY<br />is heat energy stored inside the Earth.<br />

73.
GEOTHERMAL ENERGY<br />is heat energy stored inside the Earth.<br />It can be harnessed by using a drill…<br />

74.
Like this one?<br />

75.
Um… No, Jeff.<br />

76.
Um… No, Jeff.<br />(not his real name)<br />

77.
Something more <br />like this one.<br />

78.
Anyways,<br />

79.
Drills<br />drill deep into the Earth to <br />create a geothermal well.<br />

STEAM<br />

82.
is then utilized and converted to electricity.<br />STEAM<br />

83.
You can’t just put up a geothermal plant anywhere though.<br />

84.
You can’t just put up a geothermal plant anywhere though.<br />Places near tectonic plate boundaries are the best sites, <br />

85.
You can’t just put up a geothermal plant anywhere though.<br />Places near tectonic plate boundaries are the best sites, <br />(which aren’t really that many in the world.)<br />

86.
Siting a wind turbine location is a lot more forgiving.<br />

87.
Siting a wind turbine location is a lot more forgiving.<br />There are a LOT more windy areas in the world than tectonic plate boundaries.<br />

88.
And the winner is…<br />WIND<br />‘coz:<br /><ul><li>Does NOT produce greenhouse gas emissions during conversion, unlike with biomass.

89.
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.</li></li></ul><li>So, yeah. <br />Renewable Energy<br />Scoreboard<br />3<br />WIND<br />OTHERS<br />1<br />Wind was able to PWN all the renewable energy technologies except for hydropower.<br />

90.
Wind Power’s renewable energy market growth is considerably higher than Hydropower’s though.<br />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.<br />

91.
ANYWAYS,<br />
