Renewable energy is clean energy that helps protect the
environment. Against the polluting effects and the exhaustion of fossil fuels,
renewable energies are already an alternative. In Removable we speak now of
solar energy, wind, biomass, geothermal, hydropower, hydrogen, ocean energy and
more.
Renewable energy comes from natural sources are
inexhaustible. Energy from sources likes sun, wind, water, biomass and so on.
Despite belonging to these inexhaustible sources, constant
and increasing pollution in the environment has made in recent years its
resources have diminished significantly endangering its continuity and not only
that but many animals have died, as well as the danger threatening the
conservation of land and our own species.
Renewable Energy from Fossil
Against the polluting effects of fossil fuels like oil or
coal, renewable energies are less carbon emissions, recycled and are more
respectful of the environment.
Fossil fuels create greenhouse gas emissions that contribute
to global warming. Renewable energies do not emit greenhouse gases and are
essential to curb global warming and climate change.
The production of renewable energy locally, reducing
transport costs with fossil fuels. Increasing renewable energy creates jobs.
Renewable energies for their availability are subject to
less price fluctuations, unlike oil or gas.
Unlimited potential versus the finite resources of fossil
fuels, renewable energies offer virtually unlimited potential.
Renewable Energy Types
Solar energy
Solar energy transforms sunlight into electricity. It does
directly using photovoltaic, or indirectly through concentrated solar energy.
The concentrated solar power systems use lenses or solar
panels that collect energy from the sun. Photovoltaic uses solar panels and
semiconductor materials, thus converts sunlight into electricity through the
photoelectric effect.
Solar thermal
Solar thermal energy uses the sun's energy to generate heat
or thermal energy. The energy collected by solar collectors or solar energy is
concentrated and used to heat water for domestic or industrial level
Wind power
The wind force is converted into electricity by wind
turbines. Wind farms can have hundreds of wind turbines. The wind turns the
blades on turbines that turn, are connected to a generator that produces
electricity.
Geothermal energy
The energy obtained from the use of the heat generated
inside the earth. We see the power of this energy in volcanoes or geysers.
Water vapor to pass through a turbine connected to a generator produces
electricity.
Renewable energies Hydropower
Harnesses the energy of falling water from a height. This
type of energy is converted into kinetic energy. The water moves at high speed
through the turbines and generators is transformed into electricity.
Biomass
Through photosynthesis, plants capture energy from the sun.
The energy stored in wood, fruit peel, plants, and other organic waste, the
burning will release stored energy. This is the energy of the biomass.
Ocean energy
The best known is tidal, but also working on wave energy and
temperature gradients between the bottom and surface of the ocean.
The tidal power exploits the differences in height between
the average height of the seas as the relative position of the earth and the
moon, sometimes these differences in height meters can be reached. An
alternator is used to generate electricity
Hydrogen
A very abundant element in the universe, but is rarely found
in pure state, so to get it is needed for other sources of energy. Hydrogen can
transform into energy using a similar manufacturing batteries that convert
chemical energy into electricity.
Thermal energy
The energy released through the heat obtainable from the
sun, nature, by friction, by combustion so on.
Renewable energy is considered when using hydrogen in place
of uranium in the process of nuclear fission.
Advantages of Renewable Energy
Wind power
Renewable energy has a number of advantages over fossil
fuels. We begin to see what they are:
Renewable energy, as its name suggests, can be reused, ie,
they are not perishable energy sources, as are coal, oil or nuclear materials
used for energy. The energy from the wind (wind), sea (hydraulic) or sun
(solar) is inexhaustible, or at least, no prospects that are going to end.
Therefore, they are sources of energy that will always be present and that will
survive the exploitation of other fuels.
Renewable energies help care for the environment. Most do
not need to be energy combustion, as happens in refineries or industrial plants
that use non-renewable energy. They also help preserve longer the resources of
our planet.
Solar energy
Renewable energies help stop the spread of greenhouse gases.
Reduce the degree of air pollution, emissions and weather effects such as acid
rain.
Many of these energies, such as solar energy, allow
self-sufficiency through the simple installation of infrastructure. Hence
traditional power and oil fight tooth and nail to prevent the development of
this type of energy that could allow people to be self-sufficient and without
the services of these companies.
Finally, it notes that renewable
are increasingly necessary in a world where the sustained and sustainable
development is increasingly important. This result in the existence of
increasingly specialized jobs related to these relatively new ways of obtaining
energy.
