Presentation Transcript

  1. ENERGY RESOURCES PRESENTATION BY- RAJWARDHAN SAWANT AMEY SAWANT

  2. GROWING ENERGY NEEDS - • Global Electricity Demand to Increase 57% by 2050. China and India accounted for 70% of this growth. • Increasing Population, GDP growth, Enhanced access will lead to electricity doubling of demand.

  3. FEATURES OF RENEWABLE & NON RENEWABLE SOURCES OF ENERGY- NON RENEWABLE SOURCES • AVAIBILTY-LIMINTED • NATURE-EXHAUSTIBLE • COST-Require huge capital expenditure • Response to Environment-Cause soil, water and air pollution RENEWABLE SOURCES • AVAIBILITY-In ABUDANCE • NATURE- INEXHUASTIBLE • Renewed in a short period of time. • Response to environment-They are ECO-FRIENDLY. • Cost-Cost comparatively Cheaper & Viable

  4. NON-RENEWABLE SOURCES-

  5. COAL & ITS ENVIRONMENTAL IMAPCT- Single largest contributor of Green House gases. Burning of coal causes Acid Rain , Smog & Ground Level Ozone Burning of coal produces CO2,NO2,SO2,Methane etc.

  6. OIL & ITS ENVIRONMENTAL IMPACT- Petroleum products give out the following emissions:- • Carbon dioxide (CO2) • Carbon monoxide (CO) • Sulphur dioxide (SO2) • Nitrogen oxides (NOX) • Particulate matter (PM) • Lead and various air toxics.

  7. OIL SPILLS- EXXON VALDEZ DEEPWATER HORIZON GULF WAR

  8. RENEWABLE SOURCES

  9. HYDROELECTRIC POWER- ADVANTAGES • Low Maintenance & Operational Cost • Clean fuel source • The country can produce its own energy without being reliant on international resources. • Recreational & Tourism opportunities • Has led to economic progress in many parts of world. • Cheap source of energy DISADVANTAGES • Large forest & agricultural areas are submerged. • Resettlement of Displaced population. • Can induce Seismic Activity • Not reliable during times of droughts & Water Shortage. • Dams are Expensiveto construct.

  10. Narmada BachaoAndolan- • Displacement of 2,50,000 from their land. • Rehabilitation & Resettlement of Poor. • Loss of agricultural land(approx.37,000 hecteres). • Loss of traditional land of Tribals. • Rich downstream owners derive max. benefit • Excessive sedimentation • Received huge media coverage , support from Environmental & social activist.

  11. SOLAR ENERGY- • Pollution free & no greenhouse gasses emitted. • Decreases Fuel independence. • SUISTANABLE • No Carbon Footprints • Cheap source of energy in the long Run • Cheap to run in remote areas • A very useful source of energy in a country Like India.

  12. SOLAR PHOTOVATAIC CELL- SOLAR PHOTOVATIAC CELL IS A DEVICE WHICH CONVERTS THE ENERGY OF THE SUN INTO ELECTRICTICY BY THE PHOTOVOLTAIC EFFECT.

  13. SOLAR THERMAL ELECTRIC POWER- THE SYSTEM COLLECTS & CONCENTRATES HIGH TEMPERATURE HEAT NEEDED TO GENERATE ELECTRICITY.

  14. BIOMASS ENERGY- Generally used sources are Wood , Agricultural waste, Sugarcane Waste etc Apart from producing heat & electricity can be used to produce BIO-FUELS Its NOT a Completely clean source of energy. Can be used as a alternative to fossil fuels.

  15. BIOGAS- It is produced from Plant & Animal Waste. The residue can be used as Fertilizer. It is very popular in the Rural Sector of the economy Biogas generated from Cowdung is very popular in Rural India

  16. WIND POWER- ADVANTAGES • Renewable & Green source of energy • Very Small impact on carbon foot print • Cheapest source of energy • The country can produce its own energy without being reliant on international resources • Very useful for rural economies • LOW OPERATIONAL COST CHALLENGES • Difficult to Predict wind • Suited to a Particular region • Turbines may cause noise pollution.

  17. TIDAL & WAVE POWER- WAVE POWER • Harnessed from waves moving along the surface of the ocean using Offshore & Onshore Systems • Causes by Wind • Intensity affected from wind waves TIDAL POWER • Harnessed from the Rise & Fall of sea levels using barrages,tidal fences, dams etc. • Caused gravitational pull of moon & sun on earth. • Discontinuous source of energy

  18. GEOTHERMAL ENERGY- Does not cause significant amount of pollution Resources are Naturally Replenished Location Specific Popular in countries like NewZealand ,Iceland , Phillepeans ,Canada etc.

  19. NUCLEAR ENERGY- ADVANTAGES • One single plant can produce a very high amount of electricity. • It is Goodfor the economy • Does not emit Carbondioxide • Are Cost efficient • Can bring Jobs DISADVANTAGES • Disposal of nuclear waste is very difficult. • Radioactive waste takes years to be disposable • High risk of accident • Nuclear task could be preferred targets during war & terrorist attack • Risk of Radiation

  20. ENERGY CONSERVATION- • “The path towards sustainable energy sources will be long….India cannot resist that transition ,we must lead it”.
