Sources of Energy

• Non – Renewable: Which can’t be replenished at its consumption rate

– Coal– Petroleum – Natural Gas– Nuclear Energy

• Renewable– Solar– Wind– Geothermal– Water– Biomass– Tides

FossilFuels

74% of UK Electricity; Saudi Arabia produces 13% of world’s Oil; Russia Produces 22% of NG/ Year; China produces 38% of world’s Coal

Som

e Facts

Limited availability of fossil fuelsCO2 (GHG) emission on burning

Global Warming – Climate change – Polar Ice melting – Extreme Temp. rise – Kyoto Protocol

Power ShortageRising Price of O & GEcological HazardsAbundant sunshine

Why Renewable Energy

Renewable energy and IndiaBarriers

• High Initial capital costs• No Legal frame work for

independent Power producer

• Lack of technical or commercial skills and

information

Renewable Resource

EstimatedPotential

Achievement

Wind Power 45,000 MW 2980 MW

Biomass Power 19,500 MW 384 MW

Solar Power 20 MW/sq. km 1.74 MW/sq. km

Small Hydro Power

15,000 MW 1398 MW

Bio-Energy 1700 MW 16.2 MW

Conventional sources of Energy

– Coal– Firewood– Natural Gas– Petroleum– Nuclear

India – Reserves ( 214 Bn Tons) - Productn (330 Mn/ Annum) – Meets 67% of power requirement N-Renewable source; leaves smoke and residue; Expensive; pollutes

environment

Wide Source of energy Utilization = 8%; Smoke – pollution and Health hazards

Prime source of CH4 – Associated with fossil fuels

Proven reserves of 1.1Bn Tonnes Extractn rate = 75 Mn Barrels => reserve life of 35-40 years

Cleaner fuel; Hydrogen rich molecular structure

Huge source of Energy Environmental issues – Radioactive waste

• Hydro Power• Solar Energy

• Wind Energy• Geothermal

• Biofuel

Non – Conventional sources of Energy

Virtually free energy after dam is built – more reliable than wind solar or wave – No waste or pollution Cost - Ecosystem

30 days of Sunshine striking earth = total ‘E’ from total earths fossil fuel Sun shine – not consistent, PV technology is costly

World’s Fastest growing energy source; Pollution Free; advancing technology more efficient wind mills

Productn of energy is 3rd highest among renewable energies Hot water – Natural Steam – Geo-pressured Reservoirs – Molten Magma

Brine can salinate soil – Extracting large amt of H2O can increase seismic activity – H2S is released if water is not injected back

Supplies 14% of world’s energy consumpn – 38% of Primary energy in Developing countries

Fertilizers as Biproduct from Digester – Av. Electricity generation of 5.5KWh Per cow per day!!
