This document discusses various renewable energy sources that can be used to generate electricity, including solar power, wind energy, and tidal energy. It provides details on how each works, such as how solar cells convert sunlight into electricity and how wind turbines convert the energy of wind into electric current. The document also discusses tidal power generation using tidal forces from the moon and sun, and how turbines extract energy from moving fluids. It concludes that renewable energy can improve the environment by scoring high marks across factors like air, water, space, food, and convenience.

5. How solar cell works
 Also known as
modules
 It contain
photovoltaic cells
made from silicon
that transfer
incoming sunlight
into electricity
rather than heat
5

6. Wind Energy
 The energy of wind converted into
useful form (usually electric
current) is called wind energy.
 Winds are caused by the uneven
heating of atmosphere by the sun,
the irregularities of the earth`s
surface and rotation of the earth.

7. Tidal energy
 Tidal power is a form of
hydropower that converts
the energy obtained from
tides into electricity.
 Tides are the rising and
falling of earth`s ocean
surface caused by the
tidal forces of the moon
and sun acting on the
oceans.

8. Working of turbine
 A turbine is a rotary
mechanical device that
extracts energy from a
fluid flow and converts
into useful work.
 Moving fluid acts on the
blades so that they move
and impart rotational
energy to the rotor.

10. Advantages
 Green energy are stable
 Require less
maintenance
 No pollution
Disadvantages
 Less amount of
electricity generation
 It depends on weather
for its source of power
 Can be installed only in
rural and coastal areas

11. Conclusion
 In order to evaluate whether the renewable energy can
improve our environment, we would like to give a
simple definition of environment here, which is a
compound made up of five elements: Air, Water,
Space, Food and Convenience. If a technology can
score high marks in these five areas, then it is
definitely improving our environment.
