19. WHAT IS …….
Calorific value - The calorific value or fuel value of a fuel is the
amount of heat energy given out when one gram of the fuel is
completely burnt in excess of oxygen.
Ignition temperature - Ignition temperature is the minimum
temperature at which a volatile material will vaporize into a
gas and ignite without help from an external fire source.

20. DIFFERENT ZONES OF FLAME

21. 1) WHICH GLOBAL GOALS DO YOU THINK CLEAN COOKING
REFERS TO ?
By developing a thriving global market for cleaner, more
modern stoves and fuels, we can change the way the world
cooks and transform lives, protect the climate and the
environment, empower women, and help millions of people
around the world save time and money.

22. IDENTIFY THE GLOBAL GOALS THAT ARE
FACILITATED BY HAVING ACCESS TO CLEAN
COOKING AND FUEL ?
GOAL 7
Clean cooking is essential to addressing
energy poverty and ensuring sustainable
energy
security for billions of people.

23. IDENTIFY THE THREE
WORST STOVES FROM
AN ENVIRONMENTAL
PERSPECTIVE ?
 Simple rocketstovecontains singlecombustion chamberto ensure better
combustionand helpdirect the heat to the bottomof the pot:
 The three-stone-fireis inefficient in transforming solidfuelsto energy.In termsof
climate concern,incomplete combustionresultsin the release of blackcarbon
 Woodburnerstriple the level of harmfulpollution particlesinside homesand
shouldbe soldwith a health warning,saysscientists,who alsoadvisethat they
shouldnot be usedaround elderlypeople or children.

24. IDENTIFY THE THREE
WORST STOVES
FROM A HEALTH
PERSPECTIVE ?
 Fuel stacking : - One answer to the cookstove
conundrum might be to promote and perfect a variety of
stove types. Just as people in higher-income countries,
like the US, use various devices to cook – gas burners,
microwaves, tea kettles .
 Clay stove : - The primitive clay oven, or earthen oven
/ cob oven, has been used since time immemorial by
diverse cultures and societies, primarily for, but not
exclusive to, baking before the invention of cast-iron
stoves, and gas and electric ovens.
 Gas stove : - A gas stove is a stove that is fuelled by
combustible gas such as syngas, natural gas, propane,
butane, liquefied petroleum gas or other flammable gas.

31. NUCLEAR ENERGY
 Nuclear is a zero-emission clean energy source
 It generates power through fission, which is the process of splitting
uranium atoms to produce energy.
 The heat released by fission is used to create steam that spins a
turbine to generate electricity without the harmful by products emitted
by fossil fuels.
 It also keeps the air clean by removing thousands of tons of harmful
air pollutants each year that contribute to acid rain, smog, lung cancer
and cardiovascular disease.
 Nuclear fuel is extremely dense.
 To put that in perspective, you would need more than 3 million solar
panels to produce the same amount of power as a typical commercial
reactor or more than 430 wind turbines (capacity factor not included).

32. SOLAR ENERGY
 The Health And Environmental Benefits of Solar Energy :
 Saves water which is the main requirement for survival to flora
and fauna
 Solar energy does not pollute the air
 Widespread use of solar energy slows climate change
 Solar energy reduces the carbon footprint
 Solar energy reduces the dependence on fossil fuels
 It has Zero energy production costs
 Little or no loss of energy during transportation
 Versatile installation
 Energy produced coincides with the demand
 Impact on the environment
 Improved security of the power grid
 It has economic savings
 Positive Impact on the economy

33. CLEAN RENEWABLE ENERGY RESOURCES
There are five main types of renewable energy:
• solar energy,
• wind power,
• hydropower,
• geothermal energy,
• biomass.
Each type has pros and cons and unique
applications, and they will all undoubtedly play an
important role our clean energy future.

2. TIDAL ENERGY
3. BIOMASS ENERGY
4. WIND ENERGY
5. GEOTHERMAL ENERGY
6. NATURAL GAS
7. BIOFUELS
8. WAVE ENERGY
9. HYDROELECTRIC ENERGY
10.NUCLEAR POWER
11.SOLAR POWER

35. EXAMPLES OF RENEWABLE ENERGY
TECHNOLOGIES THAT CAN BE INCORPORATED
WITH BUILDING ENERGY SYSTEMS INCLUDE:
• Solar electric, or photovoltaic (PV), systems
• Solar thermal, including solar hot water (domestic
water heating and space heating), and solar
ventilation air preheating
• Geothermal heat pump
• Wind turbines
• Biomass systems.
More information on each technology is provided in
the following sections.

36. SOLAR ELECTRIC PV:
 PV arrays convert sunlight to electricity.
 Systems are made up of modules assembled
into arrays that can be mounted on or near a
building or other structure.
 A power inverter converts the direct current
(DC) generated by the system into grid-
quality alternating current (AC) electricity.

37. SOLAR THERMAL:
o Solar water heating can be a cost-competitive way to generate hot
water or air and eliminate both the cost of electricity or fossil fuel
as well as the associated environmental impacts.
o Solar Hot Water Systems.
o Solar hot water systems use a collector to absorb and transfer heat
from the sun to water, which is stored in a tank until needed.
o These systems are categorized by the temperature at which heat is
most efficiently delivered and the collector type that is best suited
for that delivered temperature, including low-temperature
(unglazed collectors), mid-temperature (flat-plate collectors), and
high-temperature (evacuated tube collectors).

38. GEOTHERMAL
:
 Geothermal technologies
use the heat from the
center of the earth.
 Geothermal resources
include the heat retained in
shallow ground, hot water
and rock found a few miles
beneath the earth's surface,
and extremely high-
temperature molten rock
called magma located deep
in the earth.
 Almost everywhere,
shallow ground, or the
upper 3 meters of the
earth's surface, maintains a
nearly constant
temperature of 10°–16°C.
Using geothermal heat
pumps, this heat can be
tapped to provide heating
and cooling for homes and
 Deeper and warmer
geothermal reservoirs
can be tapped directly
for heat or through
advanced technologies
for heat and electricity
generation .
 Building applications for
geothermal technologies
include geothermal heat
pumps and direct use of
the geothermal resource.
 However, because
geothermal heat pumps
are the most common
geothermal energy
technology used in
buildings, this is the only
geothermal technology
discussed further in this
paper.

39. WIND :
 Wind energy is created by uneven solar heating of the
Earth’s surface.
 This wind flow, or motion energy, can be harnessed by
modern wind turbines to generate electricity.
 Wind turbines use rotating propeller-like blades to harness
the energy in the wind and drive a turbine that generates
electricity.
 Before installing a wind turbine, it must be established that
the wind resource in a specific location is adequate.
 Wind resource is classified according to its potential to
produce electricity over an annual basis .
 Wind resource maps can determine if an area of interest
should be further explored, but wind resource at a micro
level can vary significantly.
 Therefore, it is important to evaluate the specific area of
interest before deciding to invest in wind systems.

40. BIOENERGY:
 There are many types of biomass—organic matter such as plants, residue from
agriculture and forestry, and the organic component of municipal and industrial wastes—
that can be used to produce fuels, chemicals, and power.
 Wood has been used to provide heat for thousands of years.
 This flexibility in materials has resulted in increased use of biomass technologies.
 Biomass technologies break down organic matter to release stored energy from the sun.
 The process used depends on the type of biomass and its intended end use.
 For example, biofuels and bio power can be used to provide heat or electricity for
buildings.
 Biofuels are liquid or gaseous fuels produced from biomass.
 Most biofuels are used for transportation, but some are used as fuels to produce
electricity .
 Biofuels include ethanol and biodiesel.
 Bio power is the production of electricity or heat from biomass resources.
 Bio power technologies include direct combustion, co-firing, and anaerobic digestion.
