Brooklyn, You are the only one who hasn't done their rebuttal thing. Please do that.

http://prezi.com/uii2i5uok-kk/edit/?auth_key=e9vzh8w&follow=nbqp7vqdxnu3 CLICK ON THIS LINK TO EDIT THE PREZI PROJECT! EVERYONE NEEDS TO PUT SOMETHING ON IT! You will HAVE to MAKE AN ACCOUNT to edit this! Once you click on the link, click on the Prezi symbol in the bottom left corner and either sign in or MAKE AN ACCOUNT!Okay, we are doing a Prezi. It's almost done, just hit the link, create an account and do SOMETHING on it. And we'll be done. It's pretty much done, Rylee and I have done a lot of work on it. Just please do something and you'll get full credit.

It is important you do something on Prezi! Other wise you DON'T GET CREDIT.

It's also important you do your assigned thing below.

I've done a lot of things on Prezi, and everyone needs to participate. A couple of people have edited it! Be a contributor!

Hey, if you want to get a good grade, I'd actually do you're thing. I've already done 4... So do your part please.. :)
Okay I made this chart of things each person can find a rebuttal on. I just figured this would be easier so if you could look up disadvantages of the energy source by your name that'd be great :)



Disadvantages of other Resources:
COAL:
Burning coal can cause acid rain.
Coal can be turned into gas but the science hasn't been completely figured out yet.
Transporting coal can be problematic.
Limited Stocks of coal.
burning dirty coal leads to multiple pollution problems.


BIOMASS:
1. Biomass produces greenhouse emissions. The biggest argument against biomass is that it produces carbon dioxide and other greenhouse gases.
2. It takes more energy to plant ,cultivate and harvest the crops and trees than it is worth to get a net energy gain. It also takes up more water from the earth and other fossil fuels to make the fertilizers and fuels for planting and harvesting. it also, supposedly, takes up more land for the crops and trees.
http://www.alternative-energy-resources.net/biomass-energy-disadvantages.html
  • Could contribute a great deal to global warming and particulate pollution if directly burned
  • Still an expensive source, both in terms of producing the biomass and converting it to alcohols
  • On a small scale there is most likely a net loss of energy--energy must be put in to grow the plant mass

GEOTHERMAL:
Geothermal heat is coming from deep inside of the earth's surface, and this is the main disadvantage concerning finding a suitable build location.
There are some other deciding factors that may convince a constructor to build a different type of renewable energy power plant in a different location, such as a wind turbine.
So, we have established the main disadvantages of building a geothermal energy plant mainly lie in the exploration stage. During exploration, researchers will do a land survey (which may take several years to complete) and then post their findings to the company that contracted the survey.
Many companies who order surveys are often disappointed, as quite often the land they were interested in cannot support a geothermal energy plant. To extract the heat we have to find certain hot spots within the earths crust, these are very common around volcanos and fault lines, but who wants to build their geothermal energy plant next to a volcano?
Some areas of land may have the sufficient hot rocks to supply hot water to a power station, but what if these areas are contained in harsh areas of the world (near the poles) or high up in mountains. Some very good proven spots have been found in New Zealand, Iceland, Norway and Sweden.
The questions that are usually asked during a survey are; is the rock soft enough to drill through, do the rocks deep down contain sufficient heat, will this heat be sustainable for a significant amount of time, is the environment fit for a power plant. If the answer to these basic questions is yes, a more in depth survey should go ahead. I have got this information from clean-energy-ideas.com


HYDROELECTRICITY:
the high potential for extreme damage to the local ecosystem.
the high cost of construction.
the sheer size and scale of hydroelectric dams and the possibility of the potential devastation of a dam breaking.

NUCLEAR: Some very high disadvantages of nuclear energy are:
  • Waste
  • Accidents
  • Proliferation and
  • Fuel


OIL:
Oil is a non renewable resource, so there is potential we could run out of it.
Burning oil generates carbon dioxide,
Oil contains Sulfar, which has the potential to produce acid rain.
Oil isn't near as clean or as efficient as natural gas.
Oil can be highly toxic.
Many countries where oil can be found are politically unstable.
Locating oil reserves is extremely difficult and is a long and usually unsuccessful process.


SOLAR:
  • One of the main disadvantages is the initial cost of the equipment used to harness the suns energy. Solar energy technologies still remain a costly alternative to the use of readily available fossil fuel technologies. As the price of solar panels decreases, we are likely to see an increase in the use of solar cells to generate electricity.
  • A solar energy installation requires a large area for the system to be efficient in providing a source of electricity. This may be a disadvantage in areas where space is short, or expensive (such as inner cities).
  • Pollution can be a disadvantage to solar panels, as pollution can degrade the efficiency of photovoltaic cells. Clouds also provide the same effect, as they can reduce the energy of the suns rays. This certain disadvantage is more of an issue with older solar components, as newer designs integrate technologies to overcome the worst of these effects.
  • Solar energy is only useful when the sun is shining. During the night, your expensive solar equipment will be useless, however the use of solar battery chargers can help to reduce the effects of this disadvantage.
  • The location of solar panels can affect performance, due to possible obstructions from the surrounding buildings or landscape.



TIDAL:
It changes the coastline completely and ruins the habitats of some birds, and animals.
The initial building cost is very expensive.
Silt builds up behind the barrage.
It's a big piece of sea to be cost effective.
Disrupts migration in the ocean.
Only produces electricity for 10 hours a day.

WAVE:


  • Hey these are all good things but we have to be writing about disadvantages on the others resporces not our own.. lol

WIND

bad things about WIND on that website
  • there loud
  • not constant because wind is not always at the same speed
  • we can't make wind
  • the largest single turbine available today can only provide enough electricity for 475 homes
  • birds run in to them
  • can't be but by cities (were they are needed) because there is no room, not enough wind, and loud.
  • can be damaged in thunderstorms and coast a lot to be replaced

COAL

Burning coal emits harmful waste such as carbon dioxide, sulphur dioxide, nitrogen oxides, sulphuric acids, arsenic and ash. It also emits twice as much carbon dioxide when compared with natural gas to produce the same level of heat, which increased the levels of harmful greenhouse gases emitted into the earth’s atmosphere.There is more information on how coal is harmful to us at this website

DISADVANTAGES
· It changes the coastline completely and the estuaries are flooded so any mud flats or habitats that birds or animals live on are destroyed
· Initial building cost is very expensive
· Water is not replenished, it cannot flow away so any dirt or pollution lingers around the coast much longer
· Silt builds up behind the barrage
· Disrupts creatures’ migration in the oceans
· Needs a very big piece of sea to be cost effective
· Not many sites suitable for this kind of power generation; building the barrage
· Only produces power for about 10 hours of the day
