a brief historical overview of
renewable energies. 1
Emphasis is placed on solar thermal, solar photovoltaic,
wind, geothermal thermal, solar photovoltaic, wind,
geothermal, ocean, biomass and hydro, pointing out the
advantages, disadvantages and efficiency of using renewable
energies, disadvantages and efficiency of renewable energy
use. 2.
historical concept. 3.
mankind has been shaped by the discovery
and utilization of energy. utilization of
energy. The first achievement that arose
was the use and mastery of fire.. 4.
century (XX B.C.), sails were used to capture the energy of the
wind. energy of the wind to later arise the hydraulic wheel and
the windmills, which later constituted the windmills, which later
became the main source of energy on the European continent
during the Middle Ages. energy during the Middle Ages. 5.
However, at the end of the century (XVIII) the
first experiments were carried out to use steam
as a source of energy. steam as a source of
energy, but it was not until almost a hundred
years later that James Watt built the first
"steam engine". James Watt builds the first
"Steam Engine". 6.
century (XIX), the development had not reached the point where
other sources of energy were in demand. other sources of energy
were demanded, even the main source of energy at that time
was wood. the main source of energy at that time was wood. 7.
However, since the first oil well was drilled in
1859 in the United States first oil well was
drilled in the United States of America. 8
the first oil well, a significant number of experiments were
unleashed, such as: the electric generator, the internal combustion
engine, the electric light and the automobile. automobile. 9
Finally, nuclear energy was discovered, which led to the
construction of the first nuclear reactor in the United
States of America. nuclear reactor in the United States
of America in 1942. In spite of the Despite the hopes
placed in this source of energy, in the year (1973) it only
occupied a small part of the world's of the world
production, when it was realized that more than (6,000)
tons of nuclear energy were being consumed in the
world. (6,000) tons of oil equivalent were consumed in
the world, which was when the so-called Energy Crisis
began. Energy Crisis began. 10
Currently, a distinction is made between two types
or styles of energies that come to be part of our
harnessing. part of our utilization, which are: 11
Non-renewable energies. 12
They are stored subway or terrestrially for millions of
years, and have the characteristic of being a finite
resource, for example: coal, oil, natural gas. 13
Renewable energies
are created in a continuous flow and dissipate through natural
cycles that are estimated to be inexhaustible, since 14. their
regeneration is incessant, such as:
Solar thermal
A fundamental fact in the history of solar thermal energy was
originated in Switzerland by Horace de Saussure in the year de
Saussure in the year 1767 when he invented what was called the Hot
Box. 15
