4. INTRODUCTION :-
-It is energy resources that are renewable.
-Can be naturally replenished.
-Clean, Safe and not harmful to the
environment (aka mother earth).

5. TYPES OF GREEN ENERGY

6. BIOMASS ENERGY
Biomass is biological material derived
from living, or recently living organisms.
In the context of biomass for energy this
is often used to mean plant based
material, but biomass can equally apply
to both animal and vegetable derived
material.

7. TYPES & USES OF BIOMASS ENERGY
Biomass is highly diverse in nature and classified on the basis of site of
origin, as follows:
1.Field and plantation biomass
2.Industrial biomass
3.Forest biomass
4.Urban waste biomass
5.Aquatic biomass
Uses
1.Agriculture
2.Industry
3.other

8. SOLAR ENERGY
Is produced by using photovoltaic cells,
which capture sunlight and turns that
into energy.

9. Problems & Uses of solar Energy
The sun has got to shine
-The cost of solar panels and the systems range between
$20k-40k.
-The light from the sun produces a very small amount of
energy.
Uses
1. Heat Your Swimming Pool With Solar Energy.
2. Solar Energy Can Heat Your Home.
3. Power Pumps With Solar Energy.
4. Solar Energy For Battery Charging.
5. Solar Energy For Cooking.

10. Wind Energy
-These giant pinwheels spin from strong winds which spins
a turbine of a generator to produce energy.
Equation for Wind Power

11. Uses of Wind Energy
Wind turbines can convert the energy in the wind into
mechanical power that can be used for a variety of activities
like pumping water. Wind turbines can also use generators to
convert wind energy into electricity.
Places Where apply
• Large space areas
• Fields Requires
• Winding areas

12. Hydro Water Energy
Flowing water creates energy that can be captured and
turned into electricity. This is called hydroelectric power or
hydropower. The most common type of hydroelectric power
plant uses a dam on a river to store water in a reservoir.
Water released from the reservoir flows through a turbine,
spinning it, which in turn activates a generator to produce
electricity. But hydroelectric power doesn't necessarily
require a large dam. Some hydroelectric power plants just
use a small canal to channel the river water through a
turbine.

13. Uses of Hydro water Energy
• In Agriculture.
• In pump sets.
• At offices.
• Govt organization.

14. Sustainability of Green Energy
• The success, to date, of fossil fuels being able to meet energy demand
any time required has led to a feeling of society wide unrealistic
entitlement.
• This translates into a belief that whatever we want we can always have
whenever we want it.
• This of course is leading to problems as it patently can no longer be
maintained.
• It also has lead to the development of quite unrealistic expectations as
to how far renewable can replace fossil fuels.
• Renewable energy is being tagged on to a massive existing demand led
fossil fuelled energy system that has historically grown and grown.

15. • Attempts at demand reduction and increased efficiency seem to
deliver slim savings and these are often cancelled, for example, by
people choosing higher comfort levels or just doing higher milage in
their more efficient cars.
• For a number of years I worked for a company supplying small (20 –
100 kW) wind energy systems.
• The company failed and went bankrupt mainly because of a lack of
investment and a very low profit margin on sales, certainly not for want
of potential customers.
• Apart from that it was great fun and a hugely important part in the
development of my understanding of the practical limits of renewable
energy.

16. Efficiency of Green Energy

17. Advantages & Disadvantages of Green
Energy
• Negative impact to the environment is Zero.
• Make Pollution Free Environment.
• Green energy solutions.
• Good to Everybody.
• Easy to stabilize.
• More Efficient.
Disadvantages
• Costly to stabilize.

18. Conclusion on Green Energy
• To make sure we have plenty of energy in the future, it's up to all of us to use
energy wisely. We must all conserve energy and use it efficiently. It's also up to
those who will create the new energy technologies of the future. All energy
sources have an impact on the environment.
• Concerns about the greenhouse effect and global warming, air pollution, and
energy security have led to increasing interest and more development in
renewable energy sources such as solar, wind, geothermal, wave power and
hydrogen.
• But we'll need to continue to use fossil fuels and nuclear energy until new,
cleaner technologies can replace them. One of you who is reading this might be
another Albert Einstein or Marie Curie and find a new source of energy. Until
then, it's up to all of us. The future is ours, but we need energy to get there.
