Energy resources

  1. 1. Prof Priti Thakkar SIES College Of Commerce And Economics
  2. 2. ENERGY ANIMAT E ANIMAL S HUMAN LABOUR INANIM ATE CONVEN TIONAL RENEW ABLE HYDEL FIREWO OD COAL BIO-GAS NON- RENEW ABLE COAL OIL NATURA L GAS NON CONVEN TIONAL TIDAL NUCLEA R SOLAR WIND GEOTH RMAL
  3. 3.  Renewable sources can be renewed in a human lifetime.  They are:- a. Sun b. Water c. Wind  Nonrenewable sources take longer than a human lifetime to renew.  They are:- a. Fossil Fuels.
  4. 4. RENEWABLE SOURCES OF ENERGY
  5. 5. HYDEL Water is nature’s gift to us. Water is also used to create electricity. Water power that is used to create electricity is called hydroelectric power. Dams use moving water to make electricity in places where there are large bodies of water. Hydroelectric power can run mills that produces energy.
  6. 6. OTHER RENEWABLE  HYDEL  FIREWOOD  COAL  BIO-GAS
  7. 7. NON-RENEWABLE SOURCES OF ENERGY
  8. 8.  Let’s learn about fossil fuels, which are non- renewable energy resources.  Fossil fuels are formed from the remains of plants and animals that lived and died long ago.
  9. 9. Over time, the remains of dead plants and animals are changed into energy-rich fuels, called fossil fuels. Some examples of fossil fuels are- I. Coal II. Petroleum (oil) III.Natural Gas IV.Gasoline
  10. 10. Where can we find fossil fuels? We can find these natural Resources under the Ground!
  11. 11.  As you can tell, it takes longer to get more of the nonrenewable resources.  That’s why we need to conserve our non-renewable resources.  We need to use them wisely and not waste them.
  12. 12. NON- CONVENTIONAL
  13. 13. ENERGY FROM SUN IS CALLED SOLAR ENERGY.
  14. 14.  Solar energy from the sun is a natural resource.  That means energy source can be found in nature.  Solar energy is not the only natural energy resource.
  15. 15.  Wind is found in nature.  It is natural resource.  Wind energy is used to create electricity.  Wind energy can be generated in windy places, like on mountains etc. WIND ENERGY
  16. 16. OTHER NON- CONVENTIONAL  NUCLEAR  TIDAL  GEO-THERMAL
  17. 17. Patterns of energy consumption in the World
  18. 18.  Worlds primary energy consumption is growing by 5.6%.  The Asia Pacific Region continues to lead Global energy consumption 38.1% of the world and for 67.1% of Global coal consumption.  Within the Asia Pacific countries, Coal is the dominant fuel accounting for 52.1% of energy consumption.
  19. 19.  The 20 richest countries of the World consume nearly 80% of the natural gas, 65% of oil, and 50% of coal produced each year.  These 20 countries account for less than 20% population which consumes 50% of the commercial energy supply.  There is direct co-relation between energy consumption and the level of Economic development.
  20. 20. Historical Records of Energy Crises
  21. 21. 1973 OIL CRISES An OPEC oil export embargo by many of the major Arab oil producing states, in response to western support of Israel during the Yom Kippur War. 1979 ENERGY CRISES Cause: The Iranian Revolution. 1990 SPIKE IN THE PRICE OF OIL Cause: The Gulf War.
  22. 22. The 2000-2001 CALIFORNIA ELECTRICITY CRISES Cause: failed deregulation and business corruption. THE UK FUEL PROTEST OF 2000 Cause: raise in the price of crude oil and combined with already relatively high taxation on road fuel in the UK.
  23. 23. NORTH AMERICAN NATURAL GAS CRISES ARGENTINE ENERGY CRISES OF 2004 POLITICAL RIOTS OCCURING DURING THE 2007 Burmese anti-government protests were sparked by rising energy prices.
  24. 24. COMMON CAUSES BEHIND ENERGY CRISES
  25. 25. Over dependence on conventional sources of energy, especially on hydro-carbon based fuels. Natural oil and gas shortages due to war or other political disturbances. Market failure is possible when monopoly, manipulation of markets occur. A crises can develop due to industrial actions like organized strikes and govt. embargoes. A crises could emerge after infrastructure damage such as damage to pipeline etc.
  26. 26. Over consumption. Attack by terrorists on oil production and supply plants. Political events and changes. Government/ Monarchy collapse. Changes in Laws and Policies in different countries. Natural Calamities. Inter-country War.
  27. 27. ENERGY CONSERVATION: Energy conservation means more efficient utilization of energy resource ensuring the same level of economic activities with lesser inputs of energy.
  28. 28. Measures for Energy Conservation
  29. 29. Creating Awareness. Improve efficiency of equipments, machinery and appliances. Upgrade all equipments through technology. Substitutes should be made available. Non- renewable sources should only be used when the substitutes are not available. Alternatives should be made available. Energy Audits should be made compulsory in large production units.
  30. 30. Budget allotment should be made for energy conservation plans. Improvise management and maintenance to avoid losses. Need for modernization and renovation of plants. Increasing use or railways as compared to roadways. Efficient systems for household sectors.
