Module Chapter 13 – Energy

Energy 99% - sun’s energy is renewable and indirectly produces: –Solar energy (panels) –Wind (turbines) –Water (hydropower) –Biomass (bonds of organic matter) 1% - commercial energy –Non-renewable mineral resources –Fossil fuels (oil, natural gas & coal)

Oil & Natural Gas Oil – pumped from deep in the ground to wells on the land or rigs on water –Travels through pipelines –Stored in tanks –refined Natural gas – from above the oil layer –Pumped to wells –Piped to storage

Coal & Geothermal Coal – carbonized vegetable matter deposited in the Carboniferous period –Mined from coal seams –Strip mined Geothermal – Steam from cracks in the earth –Water heated underground near hot rocks close to the core –Heat rises through the cracks in the lithosphere

Future - Quality of Energy Sources Amount of net yield Cost Government research & development Subsides & tax breaks How will dependency affect economics Vulnerability to terrorism How will it affect the environment

Crude Oil Petroleum – crude oil – decompose dead matter –Thick liquid –Contains hundreds of combustible organic compounds –Contains sulfur, oxygen & nitrogen impurities –Result of high temperature & pressure over million years

World Oil Supply 78% of crude are in 11 OPEC countries –Algeria, Indonesia, Iran (8.6%), Iraq (11%), Kuwait (9.2%), Libya, Nigeria, Qatar, Saudi Arabia (25%), the United Arab Emirates (9.3%), & Venezuela US is the most oil dependent & we can not supply our needs (only 2.9% reserves) Estimated time of depletion - 80% in years US oil drilling in Alaska is limited and will destroy the environment

Natural Gas Found above crude oil reservoirs Primarily methane (50-90%) Limited Transient fuel between carbon based fuels to hydrogen- solar based energy

Coal US has 62% of the worlds coal deposits Dirty fuel Can be used as either a gas or a liquid Produces serious environmental hazard

Nuclear Energy Nuclear fission chain reaction Constructed to contain: –Fuel rods – uranium oxide – core –Control rods that absorb neutrons –Moderator that keeps the fission moving –Coolant removes heat and steam –Containment vessel that hold the radioactive material

Renewable Energy Solar energy (panels) Wind (turbines) Water (hydropower) Biomass (bonds of organic matter)
