Electricity is an important part of our daily life and uses for
different purposes. However, electricity generation sources are
decreasing day by day and electricity mainly generates from renewable
and conventional sources of energy. Proper management to create new
conventional energy sources is challenging all over the world. Lack of
conventional sources of energy, high demand for energy, less available
land, and low budget for energy are some of the important factors that
cause poor energy management all over the world. In this paper,
different potential less attributed sources of energy are analyzed along
with their implementation techniques to mitigate high electricity demand
in near-future. This review shows that along with renewable and
conventional sources of energy, less attended energy sources would be a
potential source that can generate electricity. This review also
presents that no improved techniques are needed to implement less
attended sources of energy and can be implemented with sustainable
techniques. This study also proposes implementation techniques of
uncommon sources of energy for electricity generation with related
challenges that could emerge during the implementation of these sources
of energy. In this study, the electricity generation rate and their
corresponding applications are also depicted. Proper steps and execution
of less attended sources of energy would mitigate high energy demand all
over the world and offers a cleaner environment for livelihood.
