Renewable and non renewable energy sources, use of alternate energy sources

2. Energy Resources
• Energy may be define as the capacity to do work.
• In today's world development is imposible without energy.
• Life in impossible without energy
• Life is unthinkable without energy
• Both energy production and energy utilization are indicators
of a country's progress as it is a primary input for industrial
operation.
• The sun is the basic source of energy on earth
• Coal petroleum and natural gas, fossil fuels and are also non
renewable resources on the earth

3. Growing energy needs
• Energy is an input for developments
• It aims at human welafare covering house hold, agricultural,
transport and industrial complex
• Due to the population explosion the demand for various forms of
energy has got increased many folds
• Approximately 80% of the world's energy is produced by fossil
fuel's
• Wolrd demand for oil from 436 MT in 1960 to 3200 MT in 199
• Coal 1043 MT in 1960 to 2146 MT in 1999
• Natural gas 187 MT in 1960 to 2301 in 1999
• As per UN reports 👆👆

4. Continued
• Coal, oil, Gas, Water constituted main sources of energy in india
• Commercial consumption of energy from coal (56%) and petroleum (32%) other
sources as natural gas, water
• Traditional sources of energy - Wood, Agriculture waste and animal residue
• Industrial sector consuming about 50% of total commercial energy
• Farm sector energy consumption increased from 3.9% in 1951 to 32.5% in 1997
• India rank 3rd amongest the coal producing country in the world
• Annual consumption (per households )
• Electricity - from 7kwh to 53 kwh
• Kerosen from 6.6 kg tk 9.9kg
• Cooking gas o. 33 to 3.8 kg
• As reports as a 1970-71 to 1994-95👆

5. Renewable energy Resources
--The energy resources which can be used to
produced again and again are know as
renewable energy resources
There are many diffrent forms of
renewable energy
1. Solar energy
2. Wind energy
3. Ocean thermal energy
4. Geothermal energy
5. Biomass energy

6. Solar energy
Solar Energy
Solar power is energy from the sun that
is converted into thermal or electrical
energy. Solar energy is the cleanest and
most abundant renewable energy source
available, and the U.S. has some of the
richest solar resources in the world. Solar
technologies can harness this energy for
a variety of uses, including generating
electricity, providing light or a
comfortable interior environment, and
heating water for domestic, commercial,
or industrial use.

7. Wind Energy
Wind power or wind energy
describes the process by which the
wind is used to generate
mechanical power or electricity. ...
This mechanical power can be used
for specific tasks (such as grinding
grain or pumping water), or can be
converted into electricity by a
generator.
• Reduce emissions of green
house gas and other pollutants
• One major concern is the noise
pollution be improved

8. Ocean Thermal
energy
• The ocean cover 75% of the world
surfece
• It is the largest renewable energy
source available to contribute to
the security of energy supply
reduce green house gase
emissions
• The ocean contain two
type of energy
1. Ocean thermal energy
conversion from Sun's
heat
2. Mechanical energy
from tides and waves

9. Geothermal energy
Geothermal energy is the heat energy
from hot rock present inside the earth. ...
This heat comes from the fission of
radioactive materials which are naturally
present in these rocks. The places where
very hot rocks occur at some depth below
the surface of earth are called hot spots,
and are sources of geothermal energy.

10. Biomass energy
Biomass energy is energy generated or
produced by living or once-living
organisms. ... Biomass is organic,
meaning it is made of material that
comes from living organisms, such as
plants and animals. The most common
biomass materials used for energy are
plants, wood, and waste

11. Non- Renewable energy Sources
• They are called non renewable because they can
not be re - generated with in a short spand of time.
Non renewable sources exits in the form of fossil
fuels, natural gas, oil and coal
• Non renewable energy is energy taken from the
source that are available on the earth's in limited
quantity and will vanish fifty- sixty years from now

12. Fossil fuel
energy
Fossil fuels are fuels that come
from old life forms that
decomposed over a long period
of time. The three most
important fossil fuels are coal,
petroleum, and natural gas. ...
Coal is mostly carbon. These
fuels are called fossil fuels
because they are dug up from
underground.

13. Natural gas
Natural gas (also called fossil gas) is a
naturally occurring hydrocarbon gas
mixture consisting primarily of
methane, but commonly including
varying amounts of other higher
alkanes, and sometimes a small
percentage of carbon dioxide,
nitrogen, hydrogen sulfide, or helium.
Methane makes up 70-90% of natural
gas.

14. Nuclear energy
Nuclear energy is energy in the
nucleus (core) of an atom. Atoms
are tiny particles that make up
every object in the universe. ...
This is how the sun produces
energy. In nuclear fission, atoms
are split apart to form smaller
atoms, releasing energy. Nuclear
power plants use nuclear fission
to produce electricity.

15. Coal energy
Coal burnt as a solid fuel in coal power
stations to generate electricity is called
thermal coal. Coal is also used to produce
very high temperatures through
combustion. ... The furnace heat converts
boiler water to steam, which is then used
to spin turbines which turn generators
and create electricity.

16. Importance of Alternative source
of energy
• Environmental and economic benefits of using
renewable energy include: Generating energy that
produces no greenhouse gas emissions from fossil fuels
and reduces some types of air pollution. Diversifying
energy supply and reducing dependence on imported
fuels.
• Our demand for energy increase day by day beacuse of
the technology development
• Change in life style
• Industrialization
• Agriculture fields
