14.2 Energy Resources fossil fuel geothermal energy nuclear fission nuclear fusion

14.2 Energy Resources Fossil Fuels Fuels formed in Earth’s crust over hundreds of millions of years Coal, oil, natural gas are fossil fuels that supply energy. Most of the energy you use comes from fossil fuels.

14.2 Energy Resources Fossil Fuels (cont.) Fossil fuels cannot form as fast as they are consumed.

14.2 Energy Resources Fossil Fuels (cont.) Fossil fuels contain stored energy and burn easily. They form from decayed plants and animals that have been preserved in Earth’s surface.

Fossil Fuels (cont.) Three main forms of fossil fuels: Coal Oil 14.2 Energy Resources Fossil Fuels (cont.) Three main forms of fossil fuels: Coal Oil Natural gas

14.2 Energy Resources Fossil Fuels (cont.)

How coal is removed from Earth 14.2 Energy Resources How coal is removed from Earth Strip mines Large machinery removes layers of Earth to expose the coal It is cost effective if the coal is close to the surface Underground mines Tunnels are dug into Earth It is cost effective if the coal is deep underground

Alternatives to Fossil Fuels 14.2 Energy Resources Alternatives to Fossil Fuels Electricity doesn’t always have to come from fossil fuels. Alternative energy sources include water, wind, ocean waves, and natural heat sources.

Three Alternatives to Fossil Fuels 14.2 Energy Resources Three Alternatives to Fossil Fuels Hydroelectric power—water moves through dam, turbine generates energy. Wind energy—wind moves the blades of wind towers which is connected. Geothermal energy—geysers and volcanoes can be used to generate steam for electricity.

Nuclear Fission Atoms from uranium are split in a nuclear reactor. 14.2 Energy Resources Nuclear Fission Atoms from uranium are split in a nuclear reactor.

Nuclear Fission (cont.) 14.2 Energy Resources Nuclear Fission (cont.) When atoms split, the released energy heats water in the reactor.

Nuclear Fission (cont.)

14.2 Energy Resources Nuclear Fusion Two atoms of hydrogen, called deuterium, join together to form one atom. The same reaction powers the Sun. It produces large amounts of energy. When the fusion reaction begins, the temperature must be over 100,000,000°C.

14.2 Energy Resources Solar Energy Process of converting the Sun’s light or thermal energy into electricity Solar panels are used to capture energy from the Sun and store it for later use.

14.2 Energy Resources Solar Energy (cont.) Solar energy: clean, endless supply of energy but unreliable and not cost-effective

Biomass Organic matter that makes up plants 14.2 Energy Resources Biomass Organic matter that makes up plants Examples: corn, soybeans, grasses, trees, garbage Can be used to produce fuels for electricity and transportation Must be converted, or refined, into usable energy forms

Wave Energy Harnessing the energy of water waves is challenging. 14.2 Energy Resources Wave Energy Harnessing the energy of water waves is challenging. Requires regular, strong wave action Requires a location that will not damage turbines

14.2 Energy Resources Energy from Resources

14.3 Using Energy Resources recycling particulates conservation

Location of Natural Resources 14.3 Using Energy Resources Location of Natural Resources Found in different parts of the world Important part of economy

14.3 Using Energy Resources Manufacturing Plastics, nylon, and chemicals are common materials manufactured from fossil fuels. Petro chemical plants use petroleum to make a variety of materials you use everyday.

Recycling Reprocessing an item or natural resource 14.3 Using Energy Resources Recycling Reprocessing an item or natural resource Uses less energy than obtaining new natural resources Helps natural materials last longer How much landfill space can be saved in a year by recycling?

14.3 Using Energy Resources Recycling (cont.)

Fossil Fuel Pollution Oil and coal are toxic to organisms. 14.3 Using Energy Resources Fossil Fuel Pollution Oil and coal are toxic to organisms. Fossil fuels give off carbon dioxide, a gas that contributes to global warming. Burning coal emits sulfur dioxide, a gas that causes acid rain. Particulates are tiny particles that can damage lungs and are released by the burning of fossil fuels.

14.3 Using Energy Resources Driving Cars Americans use almost one-quarter of the world’s petroleum. Carpooling, bicycling, and walking are ways to conserve gasoline.

Advantages and Disadvantages of Alternative Energy 14.3 Using Energy Resources Advantages and Disadvantages of Alternative Energy Dams Advantage: hydroelectric power is renewable Disadvantage: destroys wildlife habitat, causes erosion, and risk of devastating floods

Advantages and Disadvantages of Alternative Energy (cont.) 14.3 Using Energy Resources Advantages and Disadvantages of Alternative Energy (cont.) Wind farms Advantage: does not permanently destroy the environment Disadvantage: they may stop birds from nesting or destroy feeding habitat

Advantages and Disadvantages of Alternative Energy (cont.) 14.3 Using Energy Resources Advantages and Disadvantages of Alternative Energy (cont.) Nuclear Power Plant Advantage: generates large amounts of heat Disadvantage: generates nuclear waste, and releases heated water into streams

Conservation Nonrenewable resources are limited. 14.3 Using Energy Resources Conservation Nonrenewable resources are limited. Nonrenewable resources replenish themselves over a very long period of time. Conserving nonrenewable resources is one of the most effective ways to prevent shortages.
