2. INTRODUCTION History: Humanity and Energy Energy Source in General Renewable Energy Sources Energy Use 3. HISTORY BETWEEN 8,000 AND 10,000 YEARS AGO >AGRARIAN COMMUNITIES: FIRE AROUND 20 CENTURIES AGO >SAILBOATS, SAILING SHIPS, AND WIND MILL : WIND 4. HISTORY 17th TO 19th CENTURIES>INDUSTRIAL REVOLUTION: FOSSIL FUELS SINCE 1882 >ELECTRICITY HAS BEEN GENERATED AT CENTRAL STATIONS: WATER 5. ENERGY SOURCE IN GENERAL ELECTRICAL GENERATING ENERGY SOURCES WIND POWER CONCENTRATED SOLAR POWER (CSP) GEOTHERMAL POWER 6. ENERGY SOURCE IN GENERAL ELECTRICAL GENERATING ENERGY SOURCES TIDAL POWER SOLAR PHOTOVOLTAICS (PV) WAVE POWER 7. ENERGY SOURCE IN GENERAL ELECTRICAL GENERATING ENERGY SOURCES HYDROELECTRIC POWER NUCLEAR POWER COAL (EVEN WITH CARBON CAPTURE AND SEQUESTRATION, CCS) 8. RENEWABLE ENERGY SOURCE RENEWABLE ENERGY IS DEFINED AS AN ENERGY SOURCE/FUEL TYPE THAT CAN REGENERATE ANDCAN REPLENISH ITSELF INDEFINITELY . 9. RENEWABLE ENERGY SOURCE WIND POWER SOLAR ENERGY GEOTERMAL ENERGY HYDROELETRIC POWER BIOMASS GAS NATURAL* NUCLEAR ENERGY* 10. ELECTRICAL ENERGY USED IN THE WORLDSource : IEA, 2007 11. ELECTRICAL ENERGY USE 12. THE WRONG USE OF NATURAL RESOURCES BRINGS CONSEQUENCES GREEN HOUSE EFFECT AIR POLLUTION GLOBAL WARMING WATER CONTAMINATION 13. ONE STEP AHEADThe word is changing. Who uses the new and better way to improve the life in the world, will certainly be more successful than who does not try to adapt at world changes. 14. CONCLUSIONNowadays, electrical energy use is a human necessity. The way how this energy is generated needs to be analyzed because every natural resource that is not renewable can finish a day. 15. DISCUSSION QUESTIONS1) Is it important to invest in renewables energy sources? Why or why not? 2) What is the principal electrical energy source in your country? 3) Does your country have problems related with electrical energy? 16.
