2. Sustainable Energy
 Sustainable energy is the sustainable use of energy, that
meets the needs of the present without compromising the
ability of future generations to meet their needs.

 Technologies that promote sustainable energy
include renewable energy sources, such as
 hydroelectricity,
 solar energy,
 wind energy,
 wave power,
 geothermal energy,
 tidal power.

4. Introduction
 Renewable Energy – “any sustainable energy source that comes from natural
environment.”
 Some Aspects of Renewable Energy
 It exists abundant in the environment
 Ready to be harnessed, inexhaustible
 It is a clean alternative to fossil fuels
 “energy that is derived from natural process that are replenished constantly” --
defined by the RENEWABLE ENERGY WORKING PARTY of the INTERNATIONAL
ENERGY AGENCY

5. Importance Of Sustainable Energy
 Sustainable energy is important because of the benefits it provides.
The key benefits are:
 1. Environmental:
Sustainable energy can avoid and reduce air emissions as well
as water consumption, waste, noise and adverse land-use impacts.
 2. Energy for future generations:
Renewables avoid the rapid depletion of fossil fuel reserves and
will empower future generations to deal with the environmental impact
of over-dependence on fossil fuels.
 3. Energy security:
Lessens our dependence on fossil and imported fuels.

6. Solar energy
 Solar energy is the energy received by the earth from the sun.
 This energy is in the form of solar radiation, which makes the production of
solar electricity possible.
 Advantages:
1. Clean and renewable energy source.
2. Causes no pollution.
 Disadvantages:
1. Expensive
2. Not created during the night and cloudy weather.

7. Wind Energy
 The conversion of energy
in which turbines convert the kinetic
energy of wind into mechanical or electric
energy that can be used for power.
 The advantage of wind energy
1.They are pollution free.
2.Using wind energy means that less fossil fuel
(coal and oil) needs to be burned to make
electricity
 The disadvantages of wind energy
1.spoil the look of the natural environment
2.Wind turbines make noise 7

8. HYDROELECRTICITY
 HYDROELECTRICITY is a form of Electricity which is
produced by water power. For e.g. DAMS…
 ADVANTAGES:
1. Once a dam is constructed, electricity can be
produced at a constant rate.
2 . The lake's water can be used for irrigation
purposes.
 Disadvantges:
1. Dams are extremely expensive to build and must
be built to a very high standard.
2.The flooding of large areas of land means that the
natural environment is destroyed.

9. BIOMASS
 Biomass is the common name for organic materials
used as renewable energy sources such as;
 wood, crops, and wastes.
 Advantages:
 Abundant and Renewable
 Less Dependency on Fossil Fuels
 Clean Energy
 Disadvantages:
 Cost
 Space

10. Non-Sustainable energy
 A form of energy which is declined
and not maintained for the future
generation.
 Non-Sustainable energy can refer to
non-renewable energy.

11. Non-renewable Energy
 A non-renewable energy (also called a finite energy)
 A resource that does not renew or replenished.
 It is believed that fossil fuels were formed over 300 million years ago.
 Non-renewable energy are:
 Fossil fuels
 Coal
 oil and
 natural gas

12. Advantage and disadvantage of fossil fuel
 The good thing is about fossil fuels is:
 Relatively less expensive to produce.
 higher demand as it tend to cost less.
 The bad thing about fossil fuels is:
 Fossil fuels are made up mainly of carbon.
 When they are burned (used) they produce a lot of carbon compounds (carbon
dioxide and other greenhouse gases)
 Air and water pollution are all consequences of using fossil fuels.

13. CONTD
 FOSSIL FUEL DEPLETION
 OIL: OPEC (Middle East) dominated, 20-40 year life
OPEC (Organization of Petroleum Exporting Countries)
 NATURAL GAS: CIS (Russian) dominated, 40-70 year life
CIS (Commonwealth of Independent States)
 COAL: Widely distributed, 80-240 year life
