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.

4. • Time for green movement.
• Shift from non renewable appliances
to renewable appliances.
• Reducing the carbon emissions.
• Creating awareness among the
people.

5. RENEWABLE SOURCES
• SOLAR
• HYDROELECTRIC
• WIND
• AGRICULTURE BIOMASS
• GEOTHERMAL
• TIDAL

13. • 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.

Home efficiency appliances

16. 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.

17. General layout

18. • 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.

20. • 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.

21. General layout

22. • 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.

23. Pico hydro power plants

24. • 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.

26. • 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)

27. Wind Electricity

28. • 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

29. General layout

30. • Require more maintenance.
• Several of these components
can be more expensive.
• Applicable mostly in high
pressure regions

32. • 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.

34. Cost is high compared
to present appliances

35. • 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.
