Miner in China, where coal is very important.
Explanation and Usages of Coal
Coal comes from:North Eastern
PennsylvaniaWest Virginia KentuckyWyomingTexas North DakotaMontana
Main usages of Coal:ElectricityExportsIndustries
Types of Coal:Sub bituminousBituminousLigniteAnthracite
Process of CoalFirst, giant machines
dig out the coal. There are two ways to do this:Surface Mining
Machines remove the top layer of soil exposing coal less than 200 ft. under ground.
Underground Mining Miners ride elevators
several hundreds of feet under, then run machines down these elevators to get the coal.
Next coal is taken to a plant that cleans the coal and removes the impurities.
Finally a power plant makes the electricity.
Advantages and Disadvantages of Coal
Advantages Disadvantages
Plenty still remains in the world.
Can be easily transportedCheapIs the most plentiful
energy sourceLiquefied or gasified, coal
burns cleaner.Inexpensive=lower
energy bills
Mines are dangerous and an eyesore.
Causes pollutionCoal releases the most
greenhouse gases.It’s non-renewable.Breathing in the dust can
cause a lot of harm to miners.
Contributes to acid rainReleases a lot of carbon
dioxide. Example of it’s harm:http://www.ebaumsworld.com/video/watch/80623061/
Coal FormationCoal is a fossil fuel meaning it comes from the decomposed remains of plants and animals from millions of years ago.
This is a deepwater platform in Louisiana, called Horizon, after it exploded in April 2010 it left most of the 126 workers escaped but 11 were left missing.
Explanation and Usages of Oil
Oil comes from:RussiaSaudi ArabiaIranChinaUnited States
Texas Alaska California North Dakota Louisiana
Oil is used for:InkCrayonsBubble GumDishwashing liquidDeodorantEyeglassesCDs & DVDsTiresAmmoniaHeart valves
Process of Oil First Petroleum is
separated into “fractions” those are:Light on topHeavy on bottom
Then, molecules are cracked and rearranged to add value and create more energy.
To make gas different streams of Petroleum are carefully combined.
Advantages and Disadvantages of Oil
Advantages Disadvantages
Found in lots of placesTransportable through
pipes, ships, or tankersMore drilling would mean
more oil is made in the U.S. resulting in less importation.
By drilling more, oil and gas prices will decrease
Opening restricted drilling areas will make billions in government money.
Oil spills cause environmental damage.
It’s non-renewable.Adds to global warmingPrices increase as
supplies run out.Workers are in danger as
oil rigs can explode from something as simple as bad weather.
Opening more oil rigs will increase global warming.
Environmental Damage of the 2010 Oil Spill in the Gulf of MexicoThis pictures shows a bird and its surroundings entirely covered in the oil from this terrible spill. These spills cause animal’s, from the rig’s surrounding habitat, death. That is probably the fate of this bird.
This is a burner of a gas powered stove.
Explanation and Usages of Natural Gas
Natural Gas comes from: Texas California Louisiana New York Illinois Florida Canada
Types: Gas Methane Butane Propane
Natural Gas is used for: Steel Glass Paper Clothing Bricks Electricity Paints Fertilizer Plastics Antifreeze Dyes Photographic Film Medicines Explosives Industries as:
Electric Industrial Residential Commercial
Essential for many common products
Process of Natural GasFirst, scientists take
samples of rocks.Next they study the
rocks if they look promising (meaning it’s likely to find gas) drilling starts.
After gases are extracted it is taken to a processing plant where by-products are separated out.
Advantages and Disadvantages of Natural Gas
Advantages Disadvantages
Found in lots of placesTransports in pipes,
ships, or tankerDoesn’t pollute water or
ground when it’s burned.Natural gas can come in
small tanks for those without pipes
Non-renewableAdds to global warmingPrices increase as
supplies run outWorkers are in danger of
explosionsMiles per gallon is lower
in cars and trucks with natural gas.
Can cause firesIf your home isn’t
properly insulated it can be expensive to use natural gas.
Molecule of Natural GasThis picture is as the title says it is, simply a molecule of natural gas.
Video of what to do if Natural Gas is smelt: http://www.cbsnews.com/video/watch/?id=6854596n
Propane tanks at Heintz’s Propane.
Explanation and Usages of Propane
Propane can be found in:TexasCaliforniaLouisianaNew YorkIllinoisFloridaCanada
In the United States less than 2% of all energy used is made with propane’s energy.
Propane is used for:Heating homesHeating waterCooking &
Refrigerating foodDrying clothesFueling gasFireplacesBarbeque grillsFarmingTransportationHot-air balloons
Process of Propane
When natural gas is found and separated propane is a by-product of it.
Finally, it is made into usable energy.
Advantages and Disadvantages of Propane
Advantages Disadvantages
Safe to use indoorsCheapUsable in many pressure
and temperature rangesLong history of safe useEasily transportableLittle greenhouse gas
emissionsEasy to replaceIf spilled the gas goes
into the air so there is no ground contamination.
Can blow upMore expensive than
most resourcesResponsible for fires in
boats and housesWon’t work in very cold
weatherCanisters are not
refillableHard to find in some
areas of the country and/or world
Hot-Air BalloonsThose colorful balloons with baskets at the end, guess what! Those are powered by the one and only propane!
Power plants to be built in the UK instead of older ones.
Explanation and Usages of Nuclear Energy
Nuclear energy comes from:Western United StatesAustraliaCanadaAfricaSouth America
The 2 types of Nuclear Energy reactors are:Boiling Water ReactorPressurized Water
Reactor
Nuclear Energy is used for : Electricity
20% of energy used in the United States is made using Nuclear Power.
Process of Nuclear Energy
First, atoms are split into smaller atoms, a process called fission.
Next, the fission creates heat that is used to boil water.
Then, the boiling water creates steam that turns turbine blades.
Finally, the blades drive generators that make the electricity.

Advantages and Disadvantages of Nuclear Energy
Advantages Disadvantages
No greenhouse gases A little makes A LOT of
energyThe energy obtained from
nuclear power is 10 million times more powerful than the energy that would be made in the same amount of coal.
Reliable Is unaffected by strikes
and worldwide shortages.
The waste is radioactive and harmful, thus having to be disposed of carefully.
Supplies will run out in 50 years
Power stations are at risk of being attacked
If it is needed, it takes days to shut down a power plant.
In a nuclear meltdown high dosages of radioactivity is exposed.
Nuclear Power Plant on Three Mile IslandIn 1979 a nuclear power plant on Three Mile Island, off of Harrisburg, Pennsylvania,had a mechanical failure in which the city was at risk of being exposed to radioactive material, that could cause the cities inhabitants to experience worse cancer. Luckily the issue was not that bad and no cancer caused by this could be traced.
Offshore wind turbines.
Explanation and Usages of Wind Energy
Wind energy is generated in:United States
Texas Iowa California Minnesota Washington
Europe1.8% of energy
generated in the U.S. is made with wind energy.
Wind energy is used for:Electricity
The two types of Wind machines are:Horizontal axis wind
machinesVertical axis wind
machines
Process of Wind EnergyFirst, wind turbine’s
blades collect wind’s kinetic energy.
Next, the wind over the blades creates “lift” making the turbines turn.
Finally, the blades, that are connected to a drive shaft, turn a generator to make electricity.
Advantages and Disadvantages of Wind
Advantages Disadvantages
Only cost is in building turbine (wind is free)
No greenhouse gases Few safety risks Cheap Efficient Renewable Power failures are almost
nonexistent With larger electric grids more
electricity can be created making electricity accessible to more households
Wind power can only be generated in windy areas.
Some days, there isn’t wind.Need a lot of turbines to
make a lot of energySome people say they are
ugly and ruin the countrysideWind turbines can be
destroyed by severe storms or lightening
Makes noise (the slower the more noise)
Where Wind Is Most OftenThis chart shows the areas where wind is densest. The darker the blue the more wind there is in that area. Wind turbines would be most effective in the darkest areas.
Solar Panels with sun beating down on them.
Explanation and Usages of Solar Energy
Solar Energy can be found in:Europe CaliforniaAnywhere with
sunshine
Solar energy is used for:Heat
Heat water Heat spaces in homes Greenhouses
Electricity
Process of Solar EnergyFirst, Photovoltaic
cells change sunlight to electricity, directly.
Or, in Concentrating solar power plants, they generate electricity by first, taking in the sun’s heat.
Next, they use the heat to warm a fluid.
Finally, it creates steam that powers a generator, creating electricity.

Advantages and Disadvantages of Solar
Advantages Disadvantages
Energy is freeNo greenhouse gasesRenewableEnergy production is quietYou can harness energy in
remote places.Cheaper to use in remote
places than running electric wires
Newer technologies allow for more efficient energy production on overcast days.
ExpensiveSome don’t like solar
panels look.Sun is not always
prevalentPollutants can effect the
efficiency of panels.Solar energy can only be
generated in daylight.Weather affects solar
panels efficiency.
New Ways to Make Solar PanelsThis pictures show a “solar energy tree”. This tree shown is in Milan. The circles on top of the green stalks are the panels.
This is a hydroelectric power station.
Explanation and Usages of Hydroelectric Energy
Hydroelectric Energy is popularly produced in:WashingtonCaliforniaOregon
6% of energy produced in the United States is made hydroelectrically.
The types of Hydroelectric systems are:Run-of-the-river
system The current applies
the needed pressureStorage system
Water is accumulated, then the needed amount is released for energy making.
Process of Hydroelectric Energy
First, water runs through a pipe and pushes and turns a turbine.
Finally, a turbine spins a generator making electricity.
Advantages and Disadvantages of Hydroelectric EnergyAdvantages Disadvantages
No greenhouse gasesWater used is freeRenewableDams can store water (in
the case of a drought)If needed, dams can be
shut down immediately.Simple designs=easy
repairs
Expensive to build damWhen building a dam the
surrounding area has to be flooded. (wildlife and plants affected)
If it doesn’t rain there might not be enough water to turn the turbines.
A Hydroelectric Dam in the U.S.This is the Grand Coulee Dam, it’s on the Columbia River, in central Washington. This dam holds the worlds largest hydroelectric generator.
This is a geothermal power plant.
Explanation and Usages of Geothermal Energy
Geothermal energy can be found in:The ring of fire in
Northern AmericaSouth AmericaAsiaThe Pacific coast of AustraliaIceland
Geothermal energy is used for:Heating systemsElectricityHeat pumps
Heat is pumped to the surface of earth to control above ground temperatures in buildings
The types of geothermal plants are:Dry steam plantsFlash steam plantsBinary cycle power plants
Process of Geothermal Energy
First, hot steam and water is piped out of the earth.
Finally, the hot steam and water is in a dry steam well or water well and from there is used for each different purpose.

Advantages and Disadvantages of Geothermal Energy
Advantages Disadvantages
No greenhouse gasesEnergy is fire and won’t run
outGeothermal energy reduces
acid rain 97%RenewablePower plants don’t have to
be largeAfter establishing a site for
a plant, minimal “channels” are needed to channel it. Therefore it is…
Efficient
Not many places to build power stations
Harmful gases and minerals occasionally come up, which can be difficult to control.
Proper sites for plants are not common
Sites are usually in areas where there are volcanoes or earthquakes so investors don’t want to invest their money.
Where the Energy Comes FromHeat from earth’s hot interior is actually harnessed for this energy. From earth’s hottest places, like the mantle.
This is a wood-fired power plant.
Explanation and Usages of Biomass
Biomass can be found in:CaliforniaMichiganIllinois
4% of the energy used in the United States is made with Biomass Energy.
Biomass is used for:BiodieselIndustryElectricityCommercial
The types of Biomass are:WoodSolid waste (MSW) Crops
Process of Biomass Energy
First, biomass materials are burned to make steam.
Then, the steam turns turbines in a generator. Finally, this process makes the electricity.
Advantages and Disadvantages of Biomass
Advantages Disadvantages
Cheap It uses things we would
otherwise throw away.Waste can be found
everywhere and doesn’t run out.
Doesn’t require fossil fuelsWaste needed is always
accessible Biomass can be used to
heat homesCan be produced locally
(employing locals)
There are pollutants from burning
Sometimes biomass crops are grown where we could grow food
May not have enough space to grow biomass fuel
Extraction process is expensive
Biomass burning still needs wood, which means trees will still be needed.
Current Use For Trash Currently our trash is mostly put in landfills, secondly recycled, and finally burned. With biomass we could reduce landfills by burning the waste instead.
