An Investigation Report on
RENEWABLE SOURCES OF ENERGY

Presidium School, Gurgaon

INTRODUCTION
• Energy can not be created; it can be converted from one form to other
by technical, biological and chemical means: Solar and wind energy
into heat and power energy, biomass into heat, electricity or biofuels
etc. We have all what we need of energy resources and the conversion
technologies in order to ensure a complete supply of clean and green
energy.
• Renewable energy is energy that is generated from natural processes
that are continuously replenished. There are many sources of energy
that are renewable and considered to be environmentally friendly
and harness natural processes.
• This includes sunlight, geothermal heat, wind, tides, water, and
various forms of biomass. This energy cannot be exhausted and is
constantly renewed.
• The most important feature of renewable source is that it can be
harnessed without release of harmful pollutants.
• Renewable energy supplies 18 percent of the world’s final energy
consumption, counting traditional biomass, large hydropower, and
“new” renewable (small hydro, modern biomass, wind, solar,
geothermal, and biofuels)
• Renewable energy offers our planet a chance
to reduce carbon emissions, clean the air, and
put our civilization on a more sustainable
footing.
• Renewable sources of energy are an essential
part of an overall strategy of sustainable
development.
• They help reduce dependence of energy
imports, thereby ensuring a sustainable
supply and climate protection
RENEWABLE
RESOURCES OF
ENERGY
RENEWABLE RESOURCES
● Solar Energy
● Geothermal Energy
● Wind Energy
● Biomass
● Water
SOLAR
Energy from
the sun.
WIND
Energy
from the
wind.
BIOMASS
Energy from
burning organic
or living matter.
Although some resources are renewable, such as fresh
water which falls in the form of rain, we still have only
a limited quantity of them, and the ever growing
global population constantly needs more resources to
consume. Many parts of the world have severe water
shortages, and this situation is likely to get
worse.
The technically exploitable amounts of energy in the
form of electricity, heat and chemical energy from
renewable sources exceed the current world energy
consumption by about six fold
Therefore we need to conserve them even more from
before.
OBJECTIVES OF THE
STUDY
• To understand the concept of renewable
sources of energy.
• To explore the various renewable sources of
energy.
• To be able to construct a model showing
different renewable sources of energy like
wind, water, biomass etc.
• To be able to use the knowledge in new
and concrete situations of daily life.
INSTRUCTIONAL DESIGN
• The students carried out a detailed
investigation before constructing the model.
• They explored the books, internet and other
media resources to develop an understanding
of the concept.
• After gaining information, they started
working on designing a model of a city using
various renewable sources of energy.
• In the process, they collected the various raw
materials to construct the model.
• They assembled all the necessary components
to prepare a working model.
FEATURES OF THE MODEL
The model “Tomorrow land: Where
determination meets dreams” shows a
city making use of various renewable
sources of energy namely:
• Solar Energy used to make Wind Mill
• Rain water harvesting for storage of
water in houses.
• Biogas being used a biofuel in gas
stoves

ANTICIPATED OUTCOMES
• The students were able to create a working
model to show the practical use of renewable
sources of energy like wind energy, solar
energy and conservation of sources like
water.
• The students were able to list the changes
that need to be brought our conventional
methods of environmental conservation and
judicial use of renewable sources of energy.
