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 AND
CAN REPLENISH ITSELF INDEFINITELY .

9. RENEWABLE ENERGY SOURCE
• WIND POWER
• SOLAR ENERGY
• GEOTERMAL ENERGY
• HYDROELETRIC POWER
• BIOMASS
• GAS NATURAL*
• NUCLEAR ENERGY*

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 AHEAD
The 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. CONCLUSION
Nowadays, 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 QUESTIONS
1) 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?
