Fossil Fuels and Nuclear Energy
1. Fossil Fuel-Fuels made from once living organic material. a. Coal b. Oil c. Natural Gas
Over 1, 000,000,000 tons burned in US each year
The U.S. used 6.8 Billion barrels of oil in 2013.
The U.S production of natural gas is 681 billion cubic meters/year.
2. Main Use Categories of Energy Use a. Transportation b. Manufacturing c. Cooking d. Heating and Cooling e. To run Machines and Appliances
1. Why convert? a. To make electricity b. Electricity is easier to use to run machines, appliances, and heat homes. c. Imagine trying to run your car or computer on coal
2. Coal-Fired Electricity Generation a. Coal is burned in huge boilers b. Boiler heats water to steam c. High pressure steam turns a turbine (spinning wheel with fins) d. Turbine turns a generator
e. Generator creates electric current f. Electricity is transmitted over power line to homes
1. General Ideas a. Developed countries use more energy than developing b. Canada and the US use nearly double what other countries use
2. General Ideas c. We use more because we move people, materials and goods by truck or personal vehicle d. Japan and other use trains and mass transport to move the same items.
1. Coal a. Massive swamps produced vegetation that was then covered by seas and deposits. b. Process repeated many times c. Weight, pressure and heat of layers created the coal
2. Oil a. Massive deposits of microscopic marine life dies and sank b. Process repeated many times c. Weight, pressure and heat of layers created the oil by a chemical change
Energy Resources and Fossil Fuels
Without energy nothing happens.
Environmental Science Chapter 11 Notes #2. Review Nonrenewable resources Renewable Resources Fossil Fuels The energy of fossil fuels is most commonly.
Mrs. Paul Environmental Science Pgs Many forms of energy to meet the needs of people on Earth. Heat, light, energy, mechanical energy, chemical.
The big three: coal, oil and gas
Coal is shiny black rock with energy.

Energy Resources and Fossil Fuels. Standard: SEV4a: Differentiate between renewable and nonrenewable resources Goals for today: 1. What is energy? 2.
Industrial societies spend huge amounts of energy. Much of it is supply by electricity which comes from generators in power stations.
Five main purposes: Cooking Transportation Manufacturing Heating/Cooling Generating electricity to run machines/appliances.
Unit 3 Lesson 3: Nonrenewable Resources Lesson 4: Renewable Resources
Energy Resources and Fossil Fuels Objectives: Evaluate various fossil fuels for their effectiveness as energy resources Evaluate other sources.
AIM: What is difference between between coal, petroleum and natural gas. DN: What is coal? How is it formed? HW: Article Due Friday.
The sun is the major source of energy for the earth.
Air Pollution Sources: Coal-Fired Power Plants April 13, 2011.
Energy Humans use varied energy resources Most came from solar energy Decomposition of plants, animals buried underground form fossil fuels Which.
FOSSIL FUELS. NATURAL GAS COAL OIL There are three types of Fossil Fuels which can be used for energy.
