Some examples of the effects caused by the use
of energy
Renewable energies
The dams built for the generation of
hydroelectricity, a great visual impact on the
landscape, as well as causing other problems,
such as irreversible alteration of the territory
(large areas remain under water, with the
consequent loss of villages, forests or
ecosystems).

UNIT9
Some examples of the effects caused by the use
of energy
Non-renewable energies
Any facility for the use of non-renewable sources
of energy (such as thermal and nuclear power
stations) has a considerable impact on the
landscape.

Some examples of the effects caused by the use
of energy
Non-renewable energies
The burning of fossil fuels by industries or in
cities causes considerable atmospheric pollution,
which increases the greenhouse effect.

Some examples of the effects caused by the use
of energy
Non-renewable energies
Crude oil and its derivates cause serious damage
to ecosystems if they are intentionally or
accidentally discharged during transportation or
use.

UNIT9
Some examples of the effects caused by the use
of energy
Non-renewable energies
The main problem of nuclear energy is the
generation of radioactive waste, which will
remain toxic for thousands of years. It is
difficult to find a safe place to store this
waste.
