Explanation and Usages Used for industry, electricity, and 92% of coal is used for electricity 4 types of coal - Lignite- young coal that has moisture - Subbituminous- contains 35-45% carbon - Bituminous coal- has 45-86%carbon - Anthracite- contains 86-97% carbon 1/3 of coal comes from Appalachian coal region Coal also comes from Interior Coal Region and Western Coal Region Makes 28% of our energy
Advantages Not expensive Reduces Americans to rely on foreign oil Easy to transport Produces electricity There are now “clean coal technologies” that clean sulfur from coal Found in many places especially in the United Kingdom Disadvantages Nonrenewable Takes millions of years to create Causes black lung disease Mostly causes acid rain Produces large amount of ash Mining can be dangerous and difficult
Made from the remains of plants and animals Crude oil for the U.S. comes from: Texas, Alaska, California, Louisiana, and Oklahoma ¼ of oil comes off shore Used to fuel airplanes, cars, trucks, and heating houses.
Advantages Makes it easy to transport because its liquid. Easier to get out of the ground than coal Is affordable No other technology is needed to drill oil out of the earth One of the most abundant energy resources. Disadvantages Nonrenewable Sent by ships place to place can spill the oil. Harder to find making it more expensive Releases carbon dioxide into the atmosphere Drilling endangers the environment
Made of once living things (plants & animals) Over millions of years it turns into coal, and oil. Natural gases are tiny bubbles that have no odor to it Can burn with enough lightning or fire. Measured and sold by cubic feet. Drills out the natural gas from earth
Advantages Cleanest fossil fuel Not harmful to humans Does not leave any odor or ash behind Odor is added to detect a leak Has 70% less CO 2 than other fossil fuels. Less expensive than coal Disadvantages Nonrenewable Very flammable Toxic if inhaled in large amounts indoors Harmful to animals (poison) Pipelines are very expensive because they have to be put under ground
Used to fuel vehicles, heating homes, refrigerating, cooking, and drying clothes About 2% is used for the country’s energy Naturally turns into a gas Turns into liquid when at high or low temperature Travels by underground pipelines Propane is stored in large tanks such as this one above.
Advantages Easy to replace Clean burning fossil fuel Easily stored in tanks When stored in tanks, it can be easy to transport Less expansive than gasoline Depending on the amount it can be stored anywhere as long as its in a tank to prevent explosions Disadvantages Nonrenewable Fuel is expensive Flammable Limited amount is left Can easily spill when transported Prices can increase just like gasoline
Energy in the center of an atom Energy can be released in two ways: - nuclear fission- atoms are split into smaller atoms -nuclear fusion- atoms are fused (combined) together Makes 19% of the country’s electricity How fission occurs.
Advantages Power plants don’t need big spaces In a way it does not pollute the air Fission does not contribute to global warming No greenhouse gases are released into the atmosphere from the power plants Disadvantages Very expansive Reactors last only 40- 50 years when used in the wrong way it can pollute the air Nuclear explosions make radiation which harm the human cells causing the human to get sick
Mainly used for electricity Windmills are used to collect energy Two types of wind mills: horizontal-axis and vertical-axis Horizontal axis is the best know wind machine Caused by heating of the earth’s surface Wind Cycle
Advantages Renewable as long as the sun shines, it blows air Environmentally friendly, does not let out green house gases Wind is free, gives us free energy Wind turbines can be built almost anywhere but has to have the right amount of wind Disadvantages Not always is there wind for us to receive energy Wind turbines are expensive Turbines can kill birds when they collide with the blades Windmills make noise when blades turn
Rays of sun that reach earth Can be made into thermal energy to heat water for homes and heating swimming pools. Heat green houses Used to power most calculators Solar energy is becoming more popular
Advantages Renewable Clean fuel, does not pollute the air No noise pollution Once installing solar panels there are no more costs, energy is free Never runs out unless on cloudy days Disadvantages Does not send energy to one place, requires big areas to collect energy Amount of energy depends on time of year/day and weather. When clouds are in sight we can’t get rays from the sun Installing solar panels is expensive
Energy from moving water Turbines underwater provide energy when water moves About 10% of our energy in the United States comes from hydropower Waste products are needed Does not pollute the water or air
Advantages Safe and environmentally friendly because it does not produce green house gases Renewable because it’s a natural resource Can be used for the whole world Hydro power is very inexpensive Disadvantages Hydroelectric generating stations can harm the environment Dams are expensive to build When dams are built some villages can get flooded Dams can take large amounts of space
Energy that comes from the earth Heat comes from the earth’s core (hottest part inside the earth) Geothermal makes its way to us by volcanoes and fumaroles ( holes where the gases of volcanoes are released),geysers and hot springs Geothermal activity mostly happens in an area called Ring of Fire When magma comes close to the earth’s surface it heats the ground giving off heat energy.
Advantages Renewable because heat from the earth keeps coming to us Does not pollute the air We are less depending on coal and oil Does not contribute to the greenhouse effect Disadvantages Not available in many places Some places can loose its “steam” for more than 10 years Power plants cant be built anywhere, has to have the right types of rocks
Is organic, energy comes from the sun When burned it releases heat into the atmosphere May pollute the air but not as much as fossil fuels produces CO 2 but absorbs the same amount it lets out
Advantages Cuts down on America to use fossil fuels Renewable because we are still producing waste Available in most places Its affordable Does not contain much sulfur, that which causes acid rain Disadvantages Partly causes global warming Some materials that are used to make biomass are not always available Pollutes the atmosphere Installing technology to make power is expensive Puts green house gases in the air
