India has a huge potential to move into a fully renewable electricity system by 2050, owing to an
abundance of renewable resources. If only we can optimally leverage sophisticated technologies
to harness proactive collaboration with the industry, academia and energy innovation ecosystem,
the region can move straight to affordable renewable systems. Such renewable energy systems
can works mainly on clean energy, solar energy, wind energy and other new age storage
solutions. Solar photo voltaics is the most economical electricity source and batteries satisfy the
night-time electricity demand. In addition to covering India's electricity demand for power, such
system simulation can also cover for seawater desalination and synthetic natural gas beyond
other measures.

Industrial symbiosis thought emerged two decades ago, when researchers observed that waste
and energy usage from industrial operations drastically could be decreased by using the waste of
one firm as the input of another, and sharing infrastructure such as steam or water processes.
Industrial symbiosis takes biological symbiosis as its guiding metaphor, mimicking the symbiotic
relationships found in nature, such as the clownfish cleaning the sea anemone in return for
protection from predators.

Module VI
14 a) Can the concept of industrial symbiosis be adopted in Kerala? Explain. (5)
b) 1445: out the advantages and disadvantages of industrial symbiosis. (5)
