Household renewable energy systems

  1. 1. LOOK BEFORE YOU LEAP By L.VISWANADH.
  2. 2. • Depletion of fossil fuels. • Present House hold appliances are mostly energy consuming appliances. • Production of green house gases and release of carbon emissions which are detrimental to our world. • India currently suffering from major shortage of generation capacity.
  3. 3. • Time for green movement. • Shift from non renewable appliances to renewable appliances. • Reducing the carbon emissions. • Creating awareness among the people.
  4. 4. RENEWABLE SOURCES • SOLAR • HYDROELECTRIC • WIND • AGRICULTURE BIOMASS • GEOTHERMAL • TIDAL NON RENEWABLE SOURCES • COAL • PETROLIUM • NATURAL GAS SOURCES NUCLEAR
  5. 5. • HYDROELECTRIC 35 • WIND 24 • GEOTHERMAL 0
  6. 6. • COAL • DIESEL • NATURAL GASES 104 12 45 8
  7. 7. • Basing on present consumption fossil fuels are available for only 150 years. • In INDIA coal source available up to 2050 only. • Best alternative for rapid depletion of fossil fuels.
  8. 8. • • • • • Solar panels Drain back Solar hot water systems Pico hydro power plants Mini wind turbine Home efficiency appliances
  9. 9. SOLAR PANELS • A PV module’s output is directly proportional to the amount of sunlight hitting it. • Modules produce electricity when photons (little packets of energy contained in sunlight) hit the cells and knock available electrons loose and into motion. • Minimum requirements are solar panel, charge controller, battery system, inverter.
  10. 10. General layout
  11. 11. • Tall trees, nearby buildings, roof dormers, and even chimneys can be challenging if done by sight alone. • But shade even a small amount can in some cases shut down production completely.
  12. 12. • These popular, proven performers offer simplicity, reliability, and flexibility in system design. • Focus on residential domestic hot water systems, many options exist for system configurations, ranging from pool heating to space heating and combined domestic hot water and space heating.
  13. 13. General layout
  14. 14. • Initial cost is very high. • It is mostly applicable in summer season. • But shade even a small amount can in some cases shut down production completely.
  15. 15. Pico hydro power plants
  16. 16. • Home-scale Pico hydro-electric systems can give the best renewable bang for the buck • Small houses can be lighted • Main requirements are stream, penstock, generator set, turbine, battery bank.
  17. 17. • It is mostly applicable in hilly areas • Protection of penstock from sun, slides, and other physical damage • Freezing conditions (i.e., ice plugging screens and low water levels)
  18. 18. Wind Electricity
  19. 19. • The energy will depend on the swept area and the average wind speed at the tower top. • Main requirements are Rotor (Blades & Hub), Alternator, Tail Boom & Vane, Shaft & Bearings, Slip Rings & Brushes, rectifier, battery
  20. 20. General layout
  21. 21. • Require more maintenance. • Several of these components can be more expensive. • Applicable mostly in high pressure regions
  22. 22. • Fluorescent bulb saves 80% of energy consumed by incandescent bulb • Washing machines can save energy in several ways electricity used, hot water used, and water extracted (saving energy costs during drying) • A heat pump removes heat from the outside air or the ground using phase-change materials. They can work in reverse to provide cooling in hot weather.
  23. 23. Cost is high compared to present appliances
  24. 24. • Energy conservation is the key. It will prolong the fossil energy that now exists. • Initial cost is high for all renewable energy systems so that all humans cannot afford these systems. • But we have to agree that they are our future.
