2.2. Energy policy
Malaysia has considered using and developing some sources of
renewable energy for electricity generation years ago. Many
policies and programs were implemented to promote the renewable energies [20]. For instance, the government had focused on
tax exemption and allowance [27,28]. In addition, legislations
have been introduced recently to construct a structured policy for
long term in harvesting renewable energy. National Renewable
Policy and Action Plan was launched by the Ministry of Energy,
Green Technology and Water in 2009. This plan aims to enhance
the utilisation of renewable energy in contributing towards the
national electricity supply security and sustainable socioeconomic development. Meanwhile, the future developments
and prospects of renewable energy have been planned to focus
on the various sources including biogas, biomass, solar power and
mini-hydro [17].
