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.

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 4

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.

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.

6

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 noise7

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.

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

9

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.

10

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 gas11

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.

CONTD FOSSIL FUEL DEPLETION

OIL: OPEC (Middle East) dominated, 20-40 year lifeOPEC (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
