Energy Resources What does the word RESOURCES mean

Energy Resources What does the word RESOURCES mean? Does the Earth give us resources? What could we call resources that come naturally from the Earth?

Energy Resources ENERGY RESOURCES Renewable Resources that can be reused or replaced quickly (in a lifetime) Nonrenewable Resources (from the earth) that are limited and can run out. (The earth cannot replace it quickly. )

Energy Resources Nonrenewable Resources Fossil Fuels Energy is produced by burning fossil fuels. Nuclear Formed from dead plants and animals many years ago. Oil Energy is produced by splitting atoms Coal Natural Gas

Energy Resources Oil is removed from under ground by drilling. Gasoline is from refined oil.

Energy Resources Oil After crude oil is removed from the ground through drilling, it is sent to a refinery by pipeline, ship, or barge.

Energy Resources One barrel of crude oil, when refined, produces about 19 gallons of finished motor gasoline, and 10 gallons of diesel, as well as other petroleum products. Most petroleum products are used to produce energy. For instance, many people across the United States use propane to heat their homes. Other products made from petroleum include: Ink Crayons Bubble gum Dishwashing liquids Deodorant Eyeglasses CDs and DVDs Tires Ammonia Heart valves

Energy Resources - Fossil Fuels How do we use Crude Oil? Crude oil is first pumped out of the ground and then refined. In the refining process, crude oil is heated and separated to make different products.

Energy Resources Natural Gas mostly provides heat in our homes. NOT ALL HOMES. Natural gas is moved by pipelines from the producing fields to consumers.

Energy Resources Because natural gas is colorless, odorless, and tasteless, mercaptan (a chemical that smells like sulfur) is added before distribution, to give it a distinct unpleasant odor (it smells like rotten eggs). This added smell serves as a safety device by allowing it to be detected in the atmosphere, in cases where leaks occur

Energy Resources Natural gas is used to produce: steel Clothing Glass Brick Paper Electricity Paints Fertilizers Plastics Antifreeze Dyes Photographic film Medicines Explosives.

Energy Resources - Fossil Fuels Coal is a sedimentary rock formed from plant remains. Coal is the most abundant fossil fuel produced in the US. Coal is most commonly used in power plants to produce electricity.

Energy Resources Coal miners use giant machines to remove coal from the ground. They use two methods: surface or underground mining. Coal is the most abundant fossil fuel produced in the US. It is the main fossil fuel used to generate electricity from power plants.

Energy Resources - Fossil Fuels and Electricity The circle graph shows which energy sources are used to produce electricity in the United States.

Energy Resources - Fossil Fuels Energy Transformation and Fuels When fuels are burned, the chemical energy that is released can be used to generate another form of energy, such as heat, light, motion, or electricity.

Energy Resources Let’s recall the differences: ENERGY RESOURCES Renewable Resources from the earth that can be replaced instantly or fairly quickly Nonrenewable Resources from the earth that are limited and can run out. The earth cannot replace it quickly.

Energy Resources FOSSIL FUELS ARE NONRENEWABLE!! SO, WHAT SHOULD WE USE INSTEAD? ? !!

Energy Resources ALTERNATIVE ENERGY RESOURCES (they’re renewable!!)

Energy Resources Renewable Resources: Also called Alternative Resources Hydroelectric Wind Solar Energy from water Energy from the sun. Tidal Biomass Energy From wind Geothermal Energy from living things Energy from the Earth’s core Energy from ocean tides.

Energy Resources Alternative Natural Resources: Other resources from the Earth that can be used for energy instead of fossils fuels (which are nonrenewable and running out)

Energy Resources Solar Energy: Power from the sun.

Energy Resources Hydroelectric Energy: Power from running water.

Energy Resources Hoover Dam

Energy Resources Wind Energy: Power from the wind.

Energy Resources Biomass energy: • Energy from organic material • Solid waste is burned for fuel to create steam to turn turbines to turn generators to produce electricity. Examples of waste: wood, sugar cane, plant, animal waste.

Energy Resources Plant where trash is turned into energy!!!

Energy Resources Geothermal energy: • • Energy from hot magma or hot rock inside the earth Hot rocks under ground heat water to produce steam. Holes are drilled down to the hot area Steam comes up, turns turbine which generates electricity • Example: ICELAND

Energy Resources Tidal Energy: Energy from the ocean’s tides.
