Renewable energy:

Is found in nature in unlimited quantities. An energy source

is renewable if it originates in one of the natural cycles of

the earth

Are considered renewable energy :

Solar energy

Wind energy Geothermal energy

Tidal energy

Biomass energy

Hydropower


3/16

The sources of non-renewable energy or conventional

energy:

Are the energy sources that are found in limited quantities,which, once consumed entirety cannot be replaced.

Are considered non-renewable energy:

Fossil fuels

Nuclear fuels


4/16

Solar energy is obtained by capturing the light and heat emitted by the Sun

Renewable energy

SOLAR ENERGY


5/16

Wind energy comes from wind, the kinetic energy generated by the effect

of air currents. Geothermal energy is obtained by exploiting existing heat

within the Earth similarly.

Renewable energy

WIND ENERGY


6/16

Geothermal energy is obtained by exploiting existing heat within the Earth.

Renewable energy

GEOTHERMAL ENERGY


7/16

Tidal energy is obtained taking advantage of the kinetic energy of the tides.

Biomass energy is defined as organic material used to generate energy

Renewable energy

BIOMASS ENERGY


9/16

Accordingly Hydropower is obtained from the use of kinetic and potential energy

of the water flow.

Renewable energy

12/16

Non-renewable energy sources

Fossil fuels are coal, oil and natural gas. They come from remains of living

organisms buried millions of years ago.

FOSSIL FUELS


13/16


Nuclear fuel may be uranium, plutonium, and in general all the fissile chemical

elements suitable for operating reactors

NUCLEAR FUELS


14/16


Fossil fuels:

Thermal plant

Example of use of non renewable

Nuclear fuels:

Nuclear power station

ANALYSIS AND CONCLUSIONS

Renewable energy is the cleanest because it takes the natural cycles of the planet and it

does not emit pollutants into the environment

Nonrenewable energy is the cheapest because it requires development of new technologies

Nonrenewable energy is the easiest to obtain because it is highly commercialized.

Renewable energy is the most enduring because it doesntdepend on limited resources

In conclusion we can say that today non-renewable energy is the most used because it is

cheaper than non-renewable, but when the technological development of renewable

energy reach maturity this could become cheaper than non-renewable.

Finally we can say that we prefer renewable energy because it respects the environment

and it promotes technological development.
