The turbine turns a shaft that rotates a series of magnets past copper coils in a generator to create electricity. The water returns to the river. From the powerhouse, transmission lines carry electricity to communication. Cost: $0.30 – $0.50 kwh Uses: Electricity Uses: Electricity and Fuel Uses: Electricity Cons: Impact negatively of landscape Requires significant amount of wind and land Pros: It’s a free source of energy Produces no water or air pollution Cons: Not cost effective Air Pollution Cons: Negatively Impacts the environment Can only be used by water Pros: Easily Stored Abundant, clean and safe Pros: Abundance Burns waste product 2 Hydrogen (Fuel Cells) What: Elements that have 1 proton in an electrochemical cell H + O2 H20 Where: California, Indiana and Texas Any place you can find Hydrogen How: Steam electrolysis Hydrogen (g) Unlimited Cost: 0.86 per kwh Geothermal Solar Power What: Heat from the Earth What: Energy from the sun’s rays Where: Volcanoes, hot springs, fumaroles, Pacific Ocean: Ring of Fire, underground, Earth’s layer How: Drilling brings steam up for us to use we convert it back into water Where: Far West and Far East Coasts Cost: $0.70 kwh How: Protons from the sun are stored in Solar Panels and we keep for future use Cost: $1.10 kwh Uses: Vehicles Refining Electricity Processing Food Cons: Flammable Requires Natural Gas\ Costly Uses: District Heating (Energy and electricity), Swimming in hot springs Uses: Heat and electricity Cons: Expensive and Corrosive, Global Warming Pros: Gives off Water Clean when burned Pros: Unlimited Supply Creates a Jobs 97% less acid rain when used Cons: Not reliable Creates a Waste in photovotalic cells Not Cost Efficient Large Surface Area Pros: NO air or water pollution Unlimited supply 3 Nonrenewable: Natural Gas Coal How does it form? Plants and animals died (diatoms) buried on the ocean floor and get covered by sand and silt. Over millions of years heat and pressure turned the, into oil, natural gas and gasoline. Where is it? Middle East, Europe and Asia How does it form? Dead plants and organisms How do we get it? Natural gas sits on top of oil and drill it up pipelines and trap the petroleum on top. How do we get it? Strip Mining and mining underground, rip off tops of mountains How much is left? 130 trillion cubic feet How much is left? USA 27.1% Russia 17.3% China 12.6% India 10.2 % Australia 8.6% Uses: Heat, generating electricity, travel Uses: Industrial 30.3%, Electricity 26.4%, residential 21.6%, commercial 13.9% Cost: $12 cubic feet How it is hurting the environment: Naturally seepage pollutes CO2, CO, NO2, SO2 Where is it? Europe and Asia, Asian Pacific, North America and Africa Cost: $160 per ton in 2008 now $1-15 per ton. How it is hurting the environment: Killing trees off lose O2 and CO2 habitats for animal Pollution Acid rain 4 Uranium (nuclear) How does it form? Naturally occurring in the ground (Periodic Table) Where is it? Southern East Region Top States Illinois, PA How do we get it? Uranium U235 Fission (Atoms splits) Petroleum/Oil How does it form? Plants and animals died (diatoms) buried on the ocean floor and get covered by sand and silt. Over millions of years heat and pressure turned the, into oil and gasoline. Where is it? Saudi Arabia Iran, Iraq, Kuwait, MIDDLE EAST How do we get it? Pumping in steam (heat) into the ground and drilling out by pumping up the oil How much is left? How much is left? nd Uranium 2 energy source we have left 64.3 % Use 83 million barrel per day (90%) in 2080 5 million barrels a day Uses: Electricity, weapons (atomic bomb), submarines Cost: $1.72 per kilowatts/hour How it is hurting the environment: Buried Yucca Mountains, Nevada Pollution Radio activate waste diseases poison plants and animals Uses: 36.7% * ink Medicine, heat homes, fuel gasoline, diesel, jet fuel * Dishwashing liquids Cost: $3.26 per gallon $125 barrel How it is hurting the environment: 1) Natural Seepage 2) Spills 3) Ships/ barrages 4) Drilling/ Pipelines 5 Renewable and Nonrenewable Application 1.
