Here is a brief description of solar energy, its utility, followed by its advantages, demerits and latest advancements in the utilization of solar energy. If exploited well the globe will glow with the solar energy in the coming years ahead.

1. SOLAR ENERGY
THE CHIEF RENEWABLE
RESOURCE ON EARTH
presented by
KARTHIK CHITTIBOMMA

2. SOLAR ENERGY
Solar energy is the radiant light and heat that is harnessed
through a wide range of techniques such as photovoltaics,
artificial photosynthesis, solar heating, solar thermal energy,
molten salt power plants(where molten salts are used to
transfer energy between solar towers), etc.
It is the main source for photosynthesis which makes it the
chief source of energy.

3. RENEWABLE RESOURCE
•Renewable resource is a natural resource
which replenish to replace the portion
depleted by consumption through natural
processes and its other recurring steps in a
finite time in human timescale

4. SOURCES OF RENEWABLE RESOURCE
• Solar energy
• Wind energy
• Hydraulic energy
• Geothermal energy
• Biomass and biofuel

5. HOW SOLAR ENERGY IS RENEWABLE
• Solar energy is a renewable energy source because
the Sun represents a renewable resource. The Sun
is considered renewable because is a huge and
never ending source of clean energy that could
help mankind to give up fossil fuels. Thus,
satisfying the definition.

6. • Being produced by the Sun, solar
energy is considered to be a
renewable resource because the
Sun is here to send us light and
heat for at least another 5 billion
years, which compared to our time
here on the planet, can be
considered a never ending source
of clean power.

7. APPLICATIONS OF SOLAR ENERGY
• Photovoltaics
• Artificial photosynthesis
• Molten salt power plants
• Solar heating
• Solar thermal energy

8. WHY SOLAR ENERGY FOR 21ST CENTURY
• Energy is the most powerful component that will
influence the shape of society in this 21st century.
• The cost and availability of energy significantly impacts
our quality of life, the health of national economies, the
relationships between nations, and the stability of our
environment. Hence to maintain that.

9. • In this era of rapidly evaporating fossils there must be a
alternate source which can replace and try to replenish it.
• So, could be anything better than the solar power? Of course
there are other sources too, but the solar is the coolest one out
here.
• Its cost effective. ex: wind turbines are very costlier than the
solar panels.
• To overcome the pollution via. transport by replacing the petrol
and diesel cars with solar and electric cars.

10. • Increase of population in large numbers.
• Rapidly depleting fossil fuels.
• Global warming
• To overcome the pollution caused through thermal plants.
• In the race of growth and development maintaining
sustainability is very important.
• To meet the glowing needs of this electrical world.

11. USES OF SOLAR ENERGY
• Solar heating
• Solar cooking
• To generate electricity
• To avoid pollution
• Charging batteries
• Solar water heaters
• Cost effective (comparitively)
• Minimal maintenance
• Reduce carbon footprints
• Solar panels are portable
unlike the wind mills in
hydro thermal units

12. DEMERITS OF SOLAR ENERGY
• It’s Not 100% Reliable. This means that when the sun is not
shining, there is no generation of energy.
• High Initial Capital Costs. Although the installation of solar
panels would bring immense benefits in the long run, the
upfront costs can be punitive.
• Problem of Efficiency and Complications When Moving.

13. FURTHERENCE IN SLOAR UTILITY
• Floatovoltaics – the floating solar farm
The new breakthrough in utilizing solar energy. Solar harvesting through panels
placed on water bodies (i.e) on seas and oceans.
• BIPV – Building Integrated Photovoltaics
Building integrated photovoltaics, or BIPV for short, allow people to build
solar energy generation right into their homes, businesses, and office buildings.
• Solar cell fabrics and Solar paints

14. CONCLUSION
Solar energy is a clean, immense, pollution free, hassle free
renewable source of directly utilizable energy.
This is the best of available energies that are used to meet
the current needs of the generation.
Its cost effective and emits zero pollution. If it is
exploited well it can be the future of tomorrow.

15. • It has enormous potential to generate electrical power
that can be utilized for solar cooking, solar water
heating, etc.
• It is enough capable to reduce the carbon footprints
which are being produced since ages.
• Development of this energy requires an accurate
detailed long term knowledge of potential taking into
account seasonal variations.
