2. Lets Brief you with a video

3. What is geothermal energy?

4. Structure of Earth’s layer

7. Geothermal Reservoirs

8. Geothermal Reservoirs

9. The heat energy can be brought to
the surface by following ways :
1. Directly from hot
springs/geysers
2. Geothermal heat
pump
Uses are broadly classified as :
1. Direct use
2. Indirect use

10. Direct use

11. Geothermal Concept

12. Indirect use

16. Dry steam power plant

17. Flash steam power plant

18. 9/26/2016
Binary cycle power plant

22. Alternative Energy Sources
Wind Energy
1. Wind is unpredictable
2. Not cheap
3. Relies on government
subsidies to remain
competitive
4. Takes away from
picturesque view
Solar Energy
1. Power not available at night
time or when it is cloudy
2. High cost, specially with
energy storage
3. Requires inverter to produce
AC current
4. Low efficiency ( 17 - 40 %)
5. Exotic & fragile materials
required
6. Needs a large amount of
open space

23. 1. Energy intensive,
sometimes no net gain
2. Need lots of land
3. Requires water to grow
4. Not totally clean (CO2)
5. Competes with food
production
6. Some fuels are seasonal
7. Process can be expensive
Hydroelectric Power
1. Dam failure can destroy
entire towns and kill many
2. Can lead to major
environmental damage
3. Very high upfront costs
4. When there is drought, no
power
Alternative Energy Sources
Biomass Power

25. This leads us to….

26. Disadvantage
1. Installation cost is very
high
2. It may release some
harmful, poisonous
gases that can escape
through the holes
drilled during
construction
3. Can be difficult to drill
4. Best supplies limited to
certain areas of the
world

27. Advantage
1. Renewable source of energy
2. Non- polluting and environment friendly
3. Not dependent on the weather conditions
4. Maintenance cost is very less
5. Cheap and No wastage
6. Less space is required
7. High efficiency
8. Long lasting
