  1. GLOBAL RESOURCES CEMRE ÇİSE KADIOĞLU-00102

  2. Energy Demand • To produce electricty • For heating • For machines to work • For illumination

  3. Types of Energy Sources • Renewable • Non-renewable

  4. Renewable Energy Sources • Solar power -Light pass through the solar cells photo luminescent product stores. -Also called “self luminous”.

  5. Renewable Energy Sources • Wind power -There is a current of air because of replacement of hot and the cold air.

  6. Renewable Energy Sources • Wave power -We can produce energy with the motion of water by using a generator.

  7. Renewable Energy Sources • Geothermal energy -When hot water comes out we drive the tribunes by the thermal energy.

  8. Renewable Energy Sources • Hydroelectric energy -Hydroelectric energy gets by the flow of water.

  9. Renewable Energy Sources • Biofuels -We get the energy from the living organisms or their waste.

  10. Renewable Energy Sources • Pumped storage -Pumped storage is the way of storing energy.

  11. Non-renewable Energy Sources • Fossil Fuels • Prehistoric organisms • Heating and transport • 95% of the world's total energy • Consumption increases • Efficient power stations

  12. Non-renewable Energy Sources • Transporting oil and gas is easy • Acid rains and greenhouse gases • Global warming • Mining can be dangerous

  13. Non-renewable Energy Sources • Nuclear power • No harmful gases • Large quantities of energy • Uranium • Military ships and submarines • 11% of world’s energy • Radioactive waste materials • Money is spent on safety and building power stations

  14. General Problems with Global Resources • Expensive-prices • Greenhouse effect-global warming • Pollution • Damaged lands and environment • Finite sources

  15. Alternative Resources • Green energy • Water, wind, sun and nuclear power

  16. Alternative Resources • Hydrogen combustion • gives a lot of energy while burning • gas is burnt while produced

  17. Alternative Resources • Ethanol production • A liquid fuel • No antiknock • USA uses corn, Brazil uses sugar cane • less greenhouse gases

  18. Alternative Resources • Charcoal • Warming up wood without air • Burns slowly • Much heat energy • Little contamination

  19. Alternative Resources • Photovoltaic cells • solar energy to electricity • used in power stations, transportation, heating in the buildings • Free, no waste

  20. Conversation Of The Resources • Kyoto protocol • international agreement • global warming, pollution and global resources • gas emissions
