It is a scalar physical quantity that
describes the amount of work that can be
performed by a force, an attribute of
objects and systems that is subject to a
conservation law. Different forms of
energy include kinetic, potential, thermal,
gravitational, sound, light, elastic, and
electromagnetic energy.
The electric energy
Electricity is the form of energy that results from the existence of a
potential difference between two points, which allow an electric current
between them-when placed in contact through an electrical conductor,
to obtain work. Electrical energy can be transformed into many other
forms of energy such as light energy, mechanical energy and thermal
power.
ELECTRICAL OBJECTS
We can use the electric energy to clean the clothes,
watch TV, play video games,use the telephone, etc.
Forms to obtain energy
There are two forms to obtain energy : renowables, there
are sources of energy that can not be depleted, and no
renewables, there are sources of energy that will
eventually depleted.
Principals alternative energy
wind energy
solar energy
biomass
geothermal energy
Mareomotriz
Wind energy
It is the energy of the wind. Occurs with windmills.
Solar energy
It is the energy of sun light. Plates transform solar
energy into electric energy.
Geothermal energy
It is the energy of internal caps of the Earth.
Biomass
It is the energy that produce with the organic
matter of the living beings.
Mareomotriz
It is the energy of the tide, to change the height
of sea level.
