Many harmful effects on the
environment can be observed over the past decades due to the extensive usage of
non-renewable energy. Most discussed and harmful are the ever-changing global
climate change scenarios and their aftermath. As a point of fact, a major
part of the world’s energy consumption is dependent on non-renewable
energy sources, such as petroleum, oil, coal, and gas. Unquestionably, these
fossil fuels contribute a great deal to greenhouse gas emissions, carbon
dioxide, methane, etc., which further leads to global health issues,
global warming, and climate change. With the emergence of sustainable development
as a holistic concept since the late 1980s, the issue of global warming has
been given prominent attention. It is evident that failure to curb global
warming has led to slower progress in achieving sustainable development. About
30% of energy demand is from the built environment sector, which is also
responsible for contributing 28% of carbon emissions and continues to add an
estimated 1% every year, according to reports by UN Environment [1]. Therefore,
the fossil fuel-based energy systems are antagonistic with the goals of sustainable
development agendas. Hence, using renewable sources in harnessing clean energy
for the built environment has not remained a choice but a fundamental need.
Solar energy is one of the cleanest renewable energy sources that provide solutions
to climate change and global warming. Often termed as the alternative energy
source against oil and coal-based energy sources, solar energy has the
potential for abundant availability and is an economical way with a lower
ecological and environmental footprint, leading to a better quality of life.
Thus, there is a massive amount of global interest in harnessing solar energy
for its application and development in building systems.
