Geothermal Energy
In this type of production, heat from
deep inside the earth’s crust is used to
convert water into steam, where steam
further is used in power generation. In
some places, because of seismic
activities, water naturally gets flowed
near geologic hotspots and steam is
generated, in processes like this no
extra efforts are needed to generate
steam.
Energy from Ocean
Ocean possesses very high amount of
energy, it can be utilized in two major
ways; Because of moon’s gravitation,
the sea level periodically rises;
generators which can trap the potential
energy difference between high tides
and low tides can be constructed.
Assembling underwater turbine is other
way which uses kinetic energy (flow of
water) to generate energy. These
turbines are also known as Underwater
Windmills, because its working is very
similar to windmills.
Other Key Roles in Electricity
Production
Many new biofuels need more water
than traditional biofuels, according to a
source, it is estimated that in US 8
percent of the freshwater will be
utilized just to produce biofuels.
In the hydraulic fracking, water is
poured deep in the ground which
creates cracks and allows engineers to
access the trapped oil and natural
gases. In this process a lot of water is
required, but if the extent of trapped oil
or natural gas is high, this process can
be proved as a conventional way.
Hydrogen Fuel
The most effective way of getting
energy from water is by utilizing
hydrogen from water. Hydrogen in
power cell uses oxygen to produce
electric energy. But right now it is very
difficult to use this phenomenon in
practical application because to convert
water into molecules of hydrogen and
oxygen requires a very much amount
of energy too. Because the energy
produced by hydrogen is less than the
energy needed to separate hydrogen
and oxygen, today it is not
conventional to use water directly to
generate electricity. Research is going
on to simplify the process of
converting water into hydrogen and
oxygen so that it takes less energy and
will be efficient enough for using as a
power generation method.
This application will be highly used for
vehicles as vehicles driving on
hydrogen have more efficiency than
electric cars which runs on chargeable
batteries.
Creating Water
It can be concluded with no hesitation
that in many ways, water is supporting
our life and our future and water exists
on earth’s maximum portion, but still
in many parts people find it difficult to
live because of water scarcity.
Moreover, because of pollution,
ecology is changing, and areas having
rain as a main source of water is
experiencing infrequent rain. At such
places, water is transported through
vehicles and pipelines. But what if we
could just produce water from
hydrogen and oxygen elements
wherever and whenever needed? In the
above section we have learned that
water can be separated into hydrogen
and oxygen, while giving a lot of
energy off course, we can reverse the
process and produce water. But,
because hydrogen is a combustible and
oxygen supports combustions, this
process produces lots of energy, a lot
of it. Experiments have been conducted
to confront the results, but blasts
occurred damaging all the
experimental instruments, with of
course producing water! Researchers
are continuously searching for the
better methods for better results.
