SOURCES OF ENERGY

WHAT IS A GOOD SOURCE

• Which is easily accessable
• Which is easy to store and transpot
• Be economical

Conventional
Enery

FOSSIL FUELS

• The industrial revolution made exploitation of fossil fuels possible..
• This energy was used to make the world grow
• But burning fossil fuels is not wnvironment friendly

HYDRO ELECTRICITY

• This uses kinetic energy of flowing water to generate electricity
• Dams and reservoirs constantly get refilled with water making it not a problem ...

THERMAL ELECTRICITY

• Large amount of fossil fuels are burnt whose steam runs down turbines to produce electricity.
• This converts heat energy to electric energy

NON CONVENTIAL ENERGY

SOLAR ENERGY

• This captures the energy sun radiates and converts it into electricity.
• Certain devices help absorb sun's heat and convert it for dialy use.
• These are called solar panels.

ENERGY FROM SEA

• Tides caused due to gravity are converted into electricity fixed at the openings of dams
• A similar phenomenon occurs when capturing wave energy
• The ocean's surface heats up due to the sun and this heat is used to produce ocean thermal energy

NUCLEAR ENERGY

• A process called nuclear fission crates massive amount of energy
• Nuclear energy is easy to produce and is very efficient
• But the problem is in disposing the nuclear waste which is very hazardous.

GEOTHERMAL ENERHY

• When molten rock are pushed upwards and come into contact..they generate steam which go through turbines to generate electricity.
• This is cheap and efficient but there are not many sites of production.

ENVIRONMENTAL Consequences...?

• Exploitation of resources disturbs the environment.
• This includes either the process of exploitation or the construction of the equipment like in solar cells

HOW LONG WILL OUR ENERGY SOURCES LAST...?

• Conventional sources get depleted
• So it is important we ise inexhaustable sources of energy to ensure a bright future.
