twas a great experience having my first ppt.

1. MODERN TRENDS IN NON-
CONVENTIONAL ENERGY SOURCES

2. Outcomes of Over
using Conventional
sources:
From years man has been
exploiting natural resources for
his selfhish needs. The over
exploitation led to the
depletion of these sources
along with their hazardous
outcomes such as :
Deforestation
Global warming
Ozone layer depletion

4. A new Vision:
Keeping in mind the needs of future generation , we
should move towards Non-Conventional Energy
sources for a sustainable development.

6. Solar Energy
Solar Energy is the energy from the
sun. The Sun is the ultimate source
of energy. Solar energy is the most
readily available and free source of
energy since prehistoric times. It is
estimated that solar energy
equivalent to over 15,000 times the
world's annual commercial energy
consumption reaches the earth
every year.
It can be harnessed as:
Solar water heaters
Solar cells
Solar cooker

7. Solar powered boats
Solar powered boats get their energy from the sun. Using electric motors and
storage batteries charged by solar panels and photovoltaic cells, solar powered
boats can significantly reduce or eliminate their use of fossil fuels. Solar boats
are uniquely suited to transform light energy into movement. Environmentally
friendly solar energy is an energy efficient way to power commercial oceangoing
vessels as well as leisure boats.

8. Sun 21
The “sun21” is a 45.9-foot-long specially
built solar powered boat known as a
catamaran. On its canopy like roof are 48
silicon photovoltaic cells, which collect
energy from sunlight and transmit it to a
device in one of the narrow cabins. That
device transmits the energy to the 3,600
pounds of storage batteries below the
deck. The 11-ton solar boat was powered
on the energy needed to light 10 100-
watt light bulbs. The typical speed was
3.5 knots. The solar boat has two engines
that can go up to 107 nautical miles a
day in good weather.

9. Wind Energy:
Wind energy is basically harnessing of
wind power to produce electricity.
The kinetic energy of the wind is
converted to electrical energy. When
solar radiation enters the earth’s
atmosphere, different regions of the
atmosphere are heated to different
degrees because of earth curvature.
This heating is higher at the equator
and lowest at the poles. Since air
tends to flow from warmer to cooler
regions, this causes what we call A v e r a g e W in d S p e e d
winds, and it is these airflows that are k m /h (m p h )

10. Moving trains can
produce wind power???
A speeding train, for instance,
produces tremendous gusts that
can just as easily be converted into
electricity. A couple years ago, an
Indian inventor named Santosh
Pradhan proposed a modification Now designers from the firm Yanko Design have seized
to current trains that, according to upon the same principle and developed a device that can
his calculations, would have collect wind energy from passing trains. The technology
harvested as much as 10,000 works similarly to a wind tunnel concept put forth last
year by a team of Korean designers in which miniature
megawatts of electricity each day
turbine-based generators would be strategically placed at
from trains operating in Mumbai, various spots along the walls of a subway train tunnel.
a city in India. The device, called a T-Box, differs in that it is designed to
be installed within the actual railing track itself. It consists
of a durable metallic cylinder with vents, which allow air
to flow through and rotate turbine blades housed inside.
Yanko claims that a 1000 meter stretch of railroad can be
retrofitted with about 150 T-boxes. Considering that a
train barreling down at a speed of 200 kilometers per hour
creates winds of roughly 15 miles a second, the T-boxes
could generate 2.6 KwH of electricity.

12. Hydro- Energy
Hydro energy is the energy produced
by using the potential energy stored
in water. Wherever sufficient head,
or change in elevation, could be
found, rivers and streams were
dammed and mills were built. Water
under pressure flows through a
turbine causing it to spin.
The Turbine is connected to a
generator, which produces
electricity . In order to produce
enough electricity, a hydroelectric
system requires a location with the
following features:
Change in elevation or head: 20 feet
@ 100 gal/min = 200 Watts.
100 feet head @ 20 gal/min gives the
same output. In India the potential of
small hydro power is estimated about
10,000 MW

carbonaceous waste of various Some of advantages of biomass

to the atmosphere as it absorbs the
same amount of carbon in growing as
it releases when consumed as a fuel.
Its advantage is that it can be used to
generate electricity with the same
equipment that is now being used for
burning fossil fuels
Biogas Plant Biomass Briquetting

14. Tidal Energy
Tidal electricity generation involves
the construction of a barrage across
an estuary to block the incoming and
outgoing tide. The head of water is
then used to drive turbines to
generate electricity from the elevated
water in the basin as in hydroelectric
dams.
Barrages can be designed to generate
electricity on the ebb side, or flood
side, or both. Tidal range may vary
over a wide range (4.5- 12.4 m) from
site to site. A tidal range of at least 7
m is required for economical
operation and for sufficient head of
water for the turbines

15. Geothermal Energy
Geothermal energy is thermal energy
generated and stored in the Earth.
Thermal energy is the energy that
determines the temperature of
matter.
The heat that is used for geothermal energy can be stored deep within the Earth,
all the way down to Earth’s core – 4,000 miles down. At the core, temperatures
may reach over 9,000 degrees Fahrenheit (5000 degrees Celsius). Heat conducts
from the core to surrounding rock. Extremely high temperature and pressure cause
some rock to melt, which is commonly known as magma. Magma convects upward
since it is lighter than the solid rock. This magma then heats rock and water in the
crust, sometimes up to 700 degrees Fahrenheit (370 degrees Celsius)
From hot springs , geothermal energy has been used for bathing since paleolithic
times and for space heating since ancient Roman times, but it is now better known
for electricity generation.
