  3. 3. 3/35 Introduction Renewable Energy Vs. Non-Renewable Energy [1]
  4. 4. 4/35 GEOTHERMAL ENERGY Geothermal Energy is energy stored in the form of heat beneath the surface of the solid earth. Geothermal production of energy is 3rd highest among renewable energies. It is behind hydro and biomass, but before solar and wind. Layers of Earth [2,3]
  5. 5. 5/35 Geothermal in Pakistan  According to Alternative Energy Board of Pakistan, a global seismic belt passes through Pakistan and the country has a long geological history of geotectonic events. Two-third of Pakistan lies on fault lines

  8. 8. 8/35 GEOTHERMAL USAGE 1 : Direct Use  Geothermal heat is used directly rather than for power generation  For example space heating ,greenhouse heating, Bathing and swimming, Geothermal heat pumps  Extract heat from low temperature geothermal resources  < 150 oC or 300 oF.  Applications sited near source (<10 km)
  9. 9. 9/35 GEOTHERMAL usage 2 : indirect use  Dry Steam Power Plants  Flash Steam Power Plants  Single flash  Double flash  Binary Cycle Power Plants  Combined Cycle Power Plants (Flash and Binary)
  10. 10. 10/35 KEY FEATURES  There is no pollution  This mean of power generation is Emission free  Infinite source of heat energy  It is inexpensive and prices of electricity will be Stable  Base load energy supplies low-cost energy at constant rate in order to meet the region’s continuous energy demand.
  11. 11. 11/35 OBJECTIVE  Working model of geothermal power generation  Power production to tackle the power energy crises  Get rid of use of fossil fuel  Great geothermal source potential in Pakistan  No practical work and productive plant yet

  30. 30. 30/35 CONCLUSION  It can be seen that a number of thermal springs exist in Pakistan. Studies of these springs are far from complete.  It is suggested that detailed geochemical and radiometric studies should be carried out. After the data is collected of these springs is ascertained some of them can be developed as power generation plants as in China, France, USA and Iceland.
