What is green energy?
• The energy which is renewable
• Energy which can be produced naturally
• This type of energy is safe for planet
Sources of green energy:
• Solar
• Wind
• Hydroelectric
• Ocean
• Biomass
• Geothermal
• Hydrogen
Solar:
capturing radiant energy from sunlight
and converting it into heat, electricity etc.
Benefits:
 Sunlight is functionally endless
 Zero energy production cost
 Versatile installation
 No negative impact on environment
Solar power system
Wind:
capture the energy of wind flow by using
turbines and converting it into electricity.
Benefits:
Doesn’t produce harmful product to environment
No negative affect to human
Low maintenance cost
Has huge potential
Wind turbine
Hydroelectric:
a form of energy that harnesses the power
of water in motion.
Benefits:
 Versatile
 Adjustable power production
 Much more environment friendly
Hydroelectric power plant
Ocean:
the energy carried by ocean waves , tides
salinity and ocean temperature differences.
Benefits:
 Vast and powerful
 Predictable and easy to estimate
 Long lasting energy source
Tidal power plant
Biomass:
Plant or animal material used for energy
production.
Benefits:
 Create balanced atmosphere
 Easily accesible
Energy from biomass
Geothermal:
heat derived within the sub-surface of the
earth.
Benefits:
Eco-friendly
High efficiency system with low cost
Geothermal power plant
Hydrogen:
A fuel cell combines hydrogen and oxygen to
produce electricity, heat, and water.
Benefits:
 Can be used for fuel cells
 Can be used as rocket fuel efficiently
