• Importance of energy
• Types of energy resources
• Renewable energy resources
• Non renewable energy resources

3. INTRODUCTION
The demand for energy doubles every 14 years and is taken as one of the
indicator of development. India with 16% of population consumes roughly 3% of total
energy produced in the world, in the comparison of USA which has 6.25% of world
population it consumes over 30% of energy produced. Despite continuous increase in
the energy use per capita consumption India is still very low compared the other
countries. Even today, 80% of our country population depend on fuel wood dung and
agricultural wastes. Non renewable sources of energy are not going to fulfil our needs
in future generations. Forests are also depleting due to deforestation therefore, its is
time to think for an alternative source, a renewable source

4. IMPORTANCE OF ENERGY
Energy is the capacity to do work and is required for life processes. An energy
resource is something that can produce heat, power life, move objects, or produce
electricity. Matter that stores energy is called a fuel. Human energy consumption
has grown steadily throughout human history. Early humans had modest energy
requirements, mostly food and fuel for fires to cook and keep warm.
In today society, humans consume as much as 110 times as much energy per
person as early humans. Most of the energy we use today come from fossil fuels (store
d solar energy). But fossils fuels have a disadvantage in that they are non-renewable
on a human time scale, and cause other potentially harmful effects on the
environment In any event, the exploitation of all energy sources , ultimately rely on m
aterials on planet Earth.

5. ENERGY AND ITS CLASSIFICATION
ENERGY AS A SOURCE
The source from which we get energy to perform human daily
activities are called energy resources. According to universal statement, energy is
neither be created nor be destroyed it is travelling from one source to another
source
CLASSIFICATION
Based on their availability sources of energy are broadly divided
into two types . They are
o Renewable energy resources(non-conventional)
o Non-Renewable energy resources(conventional)

6. RENEWABLE
ENERGY
RESOURCES
Renewable energy sources are also known as non-conventional energy resources.
Which are naturally replenished on a human time scale. Renewable energy
technology playing a vital role in reducing the contamination in air, this energy resou
rces are eco friendly to the environment. It does not pollute the environment in compari
son to the conventional energy technologies .
Example : solar energy, hydroelectric energy etc.

7. CLASSIFICATION
Some of the sources of Renewable energy are
o Solar energy
o Wind energy
o Tidal energy
o Bio-mass energy
o Geo-thermal energy
o Hydro electric power

8. SOLAR
ENERGY
Solar energy is radiant light and heat from the Sun that is
harnessed using a range of technologies such as solar power
to generate electricity, solar thermal energy including solar
water heating, and solar architecture

9. ADVANTAGES OF SOLAR ENERGY
o Solar energy is ecofriendly source of energy
o Solar energy is clean and pollution free
o Solar energy is safer than traditional electric current
o Solar energy is important source of renewable energy
o Solar energy can be converted into other forms of energy
DISADVANTAGES OF SOLAR ENERGY
o The initial cost of purchasing a solar system is high
o It requires a lot of space to fix solar panels

10. ADVANTAGES OF SOLAR ENERGY
o Solar energy is ecofriendly source of energy
o Solar energy is clean and pollution free
o Solar energy is safer than traditional electric current
o Solar energy is important source of renewable energy
o Solar energy can be converted into other forms of energy
DISADVANTAGES OF SOLAR ENERGY
o The initial cost of purchasing a solar system is high
o It requires a lot of space to fix solar panels

11. WIND ENERGY
Wind power or wind energy is mostly the use of wind
turbines to generate electricity. Historically, wind power
has been used in sails, windmills, windpumps Wind power is
a popular, sustainable, renewable energy source that has a
much smaller impact on the environment than burning fossil
fuels. Wind farms consist of many individual wind turbines,
which are connected to the electric power transmission
network.

12. RELATIVE MERITS OF WIND ENERGY
ADVANTAGES
o Clean and pollution free
o Earth receive vast wind energy cost effective and reliable wind power
generators developed
o Help supplying electric power to remote areas
o Low operating cost
o Economically competitive
DISADVANTAGES
o Low energy density
o Direction of wind change and is never constant ang regular
o Wind farm requires lot of space

13. TIDAL ENERGY
Tidal power or tidal energy is harnessed by converting energy fr
om tides into useful forms of power, mainly electricity using vario
us. Tidal energy has the potential for future electricity generati
on. Tides are more predictable than the wind and the sun. Among
sources of renewable energy, tidal energy has traditionally suffere
d from relatively high cost and limited availability of sites with su
fficiently high tidal ranges or flow velocities, thus constricting its
total availability.
Historically, tide mills have been used both in Europe and on the
Atlantic coast of North America.

14. BIOMASS ENERGY
Biomass is fuel that is developed from
organic materials, a renewable and sust
ainable source of energy used to creat
e electricity or other forms of power. B
iomass power is carbon neutral electri
city generated from renewable organic
waste that would otherwise be dumped
in landfills, openly burned, or left as fo
dder for forest fires.
When burned, the energy in biomass is
released as heat. If you have a fireplac
e, you already are participating in th
e use of biomass as the wood you burn
in it is a biomass fuel.

16. PROS AND CONS OF BIOMASS ENERGY
PROS
o Renewable
o Soil waste management
o Waste reduction
o Reliability
CONS
o High costs
o Space requirement
o Not eco-friendly practice
o Releases harmful gases

17. GEOTHERMAL ENERGY
Geothermal energy is heat derived within the sub-surface of the ea
rth. Water and/or steam carry the geothermal energy to the Earth’s
surface. Depending on its characteristics, geothermal energ
y can be used for heating and cooling purposes or be harnessed to
generate clean electricity. However, for electricity, generation hig
h or medium temperature resources are needed, which are us
ually located close to tectonically active regions.

18. HYDRO ELECTRIC POWER
Hydropower, or hydroelectr
ic power, is one of the old
est and largest source of
renewable energy, which
uses the natural flow of
moving water to generate
electricity. Hydropower cur
rently accounts for 37%
of total U.S. renewable
electricity generation and a
bout 7% of total U.S. el
ectricity generation.

19. ADVANTAGES OF
RENEWABLES
o Renewable energy won’t
run out
o Maintenance requirements
are very low
o Renewables save money
o Renewable energy has
numerous health and
environmental benefits
o Renewable energy reliance
on foreign energy resources
o Higher upfront cost
o Storage capabilities
o Eco-friendly with nature
o Pollution free

20. NON-RENEWABLE ENERGY
Non-renewable energy comes from
sources that will run out or will not be r
eplenished in our lifetimes—or even in many, ma
ny lifetimes.
Most non-renewable energy sources are fossil
fuels: coal, petroleum, and natural gas. Carbon
is the main element in fossil fuels. For this
reason, the time period that fossil fuels formed
(about 360-300 million years ago) is called the
Carboniferous Period.
All fossil fuels formed in a similar way. Hundred
s of millions of years ago, even before the
dinosaurs, Earth had a different landscape. It was
covered with wide, shallow seas and swampy
forests.

21. WHY SHOULD WE CONSERVE NON-RENEWABLES ?
o If once they are used up, they never replenish again or take several thousands of
Years to replenish
o They become integral part of our life, that we cannot live without these.
o So, we need to conserve fossil fuels so that we don't run out of them
o For Future Generations to Use. One huge benefit of conserving fossil fuels is that it
will save some for future generations. …
o Human, Wildlife and Environmental Health. Using fossil fuels causes pollution
o Climate change
