SOLAR ENERGY - THERMAL Conversion Technologies

1. Five Elements of Nature
with out this life cannot exist on earth
Water
Land
Air
Fire
Sky
What is the Sixth Element ?
Energy

2. Electricity : High-tech Energy
Can be converted easily to any other form of energy.
How much is the demand for electrical energy in our country ?
Domestic Electricity Consumption is increasing faster than the rate of population
growth in our Country
YEAR POPULATION ENERGY CONSUMED
1991 846 million 31.9 billion KWh
2001 1027 million 105.6 billion KWh
INCREASE 21% 232%
Indian Average Electricity consumption: 386 units/person/year.
Global Average Electricity consumption: 1000 units/person/year.

3. Methods of Generating Electrical Energy -how long?
CONVENTIONAL METHOD (Polluting)
Fossil Fuels are fast depleting
Coal consumption in power production (in Million Tonnes)
1980-81 = 34.5 1990-91 = 118.6 2000-01 =
222.6
Hydro Thermal Projects
Total contribution of 23,800 MW -depends on natural
resources which is diminishing
Oil sources and also likely to be empty
Crude oil import in increasing year after year
1990-91 = 20.7 million ton 2000-01 = 57.1 million ton
Nuclear Power Plants
2.5% of generation capacity.
Not considered due to Safety factor
