1. Introduction
Threats of climate change have drawn the attention of the world community to look for alternative
sources of energy. Petroleum fuels, coal and electricity are the primary sources of energy amongst the
developed nations. When it comes to the developing nations, it is mostly biomass. Over half of the world’s
electricity is produced by burning coal or petroleum fuels - adding more greenhouse gases, polluting the
atmosphere and leading to climate change. On the other hand, these resources are fast depleting and
their reserves will not last for more than a few more decades for humans to use. Renewable energy such
as small hydro schemes can help face both these issues.
