They would put the coal in a furnace and that would create thermal energy which than turns into kinetic. Oil- the chemicals in the oil convert to heat which can expand a metal or strip to make mechanical energy. Finally fossil fuels can make natural gases too because the fossil have absorbed the suns rays and died and still have the sun’s energy. Fossil fuels are non-renewable resources because when you take the energy out of them you can not use them again. There are also some disadvantages too, they take millions of years to create, they are non-renewable, and greenhouse gases which can led to climate change. It is also easier to transport fossil fuels than other forms of energy. **

Plants and animals capture sunlight . natural gs is used to generate electricity. wells are drilled into so natural gas can be extracted from the ground and sent to gas plants to take out any impurities. There are also some disadvantages also, it is non-renewable, releases carbon dioxide which can lead to “global warming”, and it is also very flame-able. Burning natural gas combustion engines don’t need to use much water. the water can be taken away from lakes and ponds which could kill fish and other animals in those bodies of water. These turbines do not create any water discharges. **

** Kobe : ** ** . [] ** ** coal is fossil fuel formed from the decomposition of organic materials that has been subjected to geologic heat and pressure over a million years. nonrenewable because it will not be replenished in the human time frame. coal mining creates electricity. when coal is burned, carbon dioxide, sulfur dioxide, and mercury compounds are released. coal-fired boilers reduce the amount of emissions released. ** ** [] ** ** Splitting a uranium atom in a process called fission. fission releases energy that can be used to make steam, which is used in turbines to create electricity. accounts for 19% of the united states energy. no nuclear plants have been built since 1996. Uranium oxide pellets are bombarded with neutrons causing the uranium atoms to split and release both heat and neutrons. uranium is a nonrenewable resource that cannot be replenished on a human time scale. the heat is made to create steam and power turbines for electrical energy. power plants do not emit harmful emissions but fossil fuel emissions are associated with mining for uranium and the transportation to the power plants. there is 2,000 metric tons of radioactive waste created each year. ** ** [] ** ** Hydro power is considered a renewable energy resource because it uses earths water cycles to generate electricity. the movement of water downstream creates kinetic energy that can be converted in to electrical energy. the water is pushed into a hydraulic turbine that is connected to a generator. hydro power is dependant on precipitation and elevation changes. hydro power does not release any emissions for it doesn’t burn anything, but when the dam is built it can decay the plants and they can release methane which is a potent greenhouse gas. Produces 9% of united states energy. ** ** [|http://www.diigo.com/bookmark/http%3A%2F%2Fwww.epa.gov%2Fcleanenergy%] ** ** [|2Fenergy-and-you%2Faffect%2Fnon-hydro.html?gname=mms-physical-science] ** ** non-hydroelectric energy refers to, solar, geothermal, biomass, landfill gas, and wind. is renewable. solar energy is renewable because it is constintley supplied to the earth from the sun. solar thermal technologies concentrate the suns rays with mirriors or other reflective devices to heat a liquid to create steam. which is then used to turn a generator and create electricity. geothermal energy is continuously created beneath the surface of the earth from the extreme heat contained in liquid rock. when the heat is turned into steam, it turns a turbine to generate electricity. biomass is agricultural waste that can be renewed. power plants emit nitrogen oxide and small amounts of sulfur oxide. use water to cool and steam the biomass. landfill gases is created with microorganisms cause organic waste such as food wastes and paper, to decompose in landfills. burning landfill gases produces nitrogen oxide emissions as well as trace amounts of toxic materials. **

** 1. Oil is a nonrenewable resource. ** ** 2. Oil is pumped up from the ground from holes that are drilled. ** ** 3. Oil is burned in boilers or turbines in power plants that are then transfered to energy. ** ** 4. Most of our energy comes from fossil fuels. ** ** 5. Oil is mostly used in the United States for transportation or home heating. **
