Presentation on theme: "Energy Fact or Fiction:"— Presentation transcript:
1Energy Fact or Fiction: Determine if the following statements are fact or fiction
2Fact or Fiction Petroleum is the ultimate source of energy on Earth. Traditional sources of energy come from plants.Fossil fuels are available in limitless supplies.The stored energy in petroleum originally came from the Sun.Natural gas is formed from the remains of living things.
3Fact or Fiction Alternative energy sources are renewable sources. Solar heating uses fans to distribute heat.There are no drawbacks to using hydroelectric power.Energy obtained directly from heat in the earth’s crust is called geothermal energy.
4Fact or FictionWind is one of the least expensive ways to produce electricity.Nuclear fuel is a nonrenewable resource.No greenhouse gases are released from nuclear power plants.Biomass energy sources are nonpolluting.Shale oil is profitable to extract and refine.
45Wind Energy Wind mechanical energy electrical energy Most wind farms are in California,ND, SD, and TX have the best locations10% of the world’s electricity by the year 2050
46Wind Energy Advantages: Disadvantages: virtually unlimited nonpollutingcan be built quicklyinexpensive, but only in areas with steady windsDisadvantages:not very attractivemay interfere with and even kill birdsrequires land lease/purchase
47Fact or Fiction – Answers Nuclear fuel is a nonrenewable resource.No greenhouse gases are released from nuclear power plants.Fact
48Nuclear EnergyDuring nuclear fission, atoms are split, releasing large amount of energyUranium is commonly used17% of the world’s electricity
53Fact or Fiction – Answers Biomass energy sources are nonpolluting.Fiction
54BiomassBiomass is a renewable energy resource – as long as the organisms are replaced.Not wood, field cropsDisadvantagerelease carbon dioxide and particulate matter
55Biomass Ethanol Methanol Made from sugar and grain crops Grain alcohol Made mostly from natural gasWood alcohol
56Biomass Biogas Biodiesel Made from plant and animal waste Manufactured from vegetable oils, animal fats, or recycled restaurant greases
57Fact or Fiction – Answers Shale oil is profitable to extract and refine.Fiction
58Energy from Oil Shale and Tar Sand Oil shale is heated to form oil known as shale oil.The cost of processing oil shale is higher than the cost of traditional crude oil.requires lots of energyproduces air and water pollution
