  2. Energy Defined • 3 min video •

  3. HMMMM.... What do you think nonrenewable resources are? Break it down... Nonrenewable? Resource?

  4. NONRENEWABLE RESOURCES A nonrenewable resource is a natural resource that cannot be re-made or re-grown at a scale comparable to its consumption.

  5. Renweable Resource is… • A renewable resource is a natural resource which can replenish with the passage of time, either through biological reproduction or other naturally recurring processes.

  6. Energy Use in USA

  7. Five Factors that Influence the Value of Fuel • Cost • Availability • Safety • Energy Content • Byproducts of the fuel’s use

  8. USA vs World

  9. NUCLEAR ENERGY Nuclear fission uses uranium to create energy. Nuclear energy is a nonrenewable resource because once the uranium is used, it is gone!

  10. How Nuclear Energy Works

  11. A 1,000-megawatt nuclear plant is refueled once a year, whereas a coal plant of the same size requires 80 rail cars of coal a day

  12. COAL, PETROLEUM, AND GAS Coal, petroleum, and natural gas are considered nonrenewable because they can not be replenished in a short period of time. These are called fossil fuels.

  13. HOW IS COAL MADE ???



  16. Differences Coal is a solid. It is mostly carbon. It is made from mostly plant materials. Oil is a liquid. It is a mixture of hydrocarbons. It is more animal materials. Its composition is different depending on where it is found. Natural gas is a gas. It is mostly methane, CH4.

  17. Heat produced by burning pulverized coal in a furnace boils water to produce steam that spins a turbine to produce electricity. The steam is cooled, condensed, and returned to the boiler for reuse. Waste heat can be transferred to the atmosphere or to a nearby source of water. The largest coal-burning power plant in the United States, located in Indiana, burns three 100-car trainloads of coal per day Coal-burning power plant.

  18. Lowest Boiling Point Gases Science: refining crude oil. Components of petroleum are removed at various levels, depending on their boiling points, in a giant distillation column. The most volatile components with the lowest boiling points are removed at the top of the column. Gasoline Aviation fuel Heating oil Diesel oil Naphtha Grease and wax Heated crude oil Asphalt Furnace Highest Boiling Point

  19. Methane Hydrates-fossil fuel of future? As natural gas from shale becomes a global energy "game changer," oil and gas researchers are working to develop new technologies to produce natural gas from methane hydrate deposits.

  20. Methane risks Methane hydrates are sensitive sediments. They can rapidly dissociate with an increase in temperature or a decrease in pressure. This dissociation produces free methane and water The conversion of a solid sediment into liquids and gases will create a loss of support and shear strength. These can cause submarine slumping, landslides or subsidence that can damage production equipment and pipelines

  21. Oil Reserves vs Oil Resources • Oil reserves are oil deposits that can be extracted profitably at current prices using current technology. • Oil resources are quantities of petroleum estimated to be potentially recoverable from undiscovered accumulations by application of future development projects.

  22. HMMMM.... If nonrenewable resources are resources that cannot be re-made at a scale comparable to its consumption, what are renewable resources?

  23. RENEWABLE RESOURCES Renewable resources are natural resources that can be replenished in a short period of time. ● Solar ● Geothermal ● Wind ● Biomass ● Water

  24. SOLAR Energy from the sun. Solar power is the conversion of sunlight into electricity, either directly using photovoltaics (PV), or indirectly using concentrated solar power (CSP)

  25. Passive Solar Collection


  27. Solar Cooking keeps Trees

  28. GEOTHERMAL Geothermal energy is the heat from the Earth. It's clean and sustainable. Resources of geothermal energy range from the shallow ground to hot water and hot rock found a few miles beneath the Earth's surface, and down even deeper to the extremely high temperatures of molten rock called magma.

  29. Geo-Thermal Energy

  30. WIND . Wind power is the conversion of wind energy into a useful form of energy, such as using wind turbines to make electrical power, windmills for mechanical power, windpumps for water pumping or drainage, or sails to propel ships.

  31. How Wind Turbines Work

  32. Wind Power •

  33. Wind Power is like “oil” to Mid-West & Coastal Areas

  34. BIOMASS Energy from burning organic or living matter. As an energy source, biomass can either be used directly via combustion to produce heat, or indirectly after converting it to various forms of biofuel.

  35. Bio Diesel

  36. Ethanol Fuel

  37. Green Algae • • Algae fuel or algal biofuel is an alternative to fossil fuel that uses algae as its source of natural deposits

  38. WATER or HYDROLOGIC Energy from the flow of water.

  39. Tidal and Wave Power • •

  40. Tidal Power • Tidal power, also called tidal energy, is a form of hydropower that converts the energy of tides into useful forms of power, mainly electricity.

  41. WAVE POWER • Wave energy is produced when electricity generators are placed on the surface of the ocean. The energy provided is most often used in desalination plants, power plants and water pumps. Energy output is determined by wave height, wave speed, wavelength, and water density
