The Renewable Energy Act 2011 focuses on only four sources
of renewable energy in electricity generation, namely: biogas,
biomass, small hydropower and solar photovoltaic. Malaysia has
promoted and developed these four sources since 1990s [30–33].
This is also not including the recent development on wind energy
as highlighted in Pulau Perhentian, Sabah and Sarawak [34,35].
Therefore, one of main reasons in selecting these four sources in
the Act is mainly due to their levels of implementation and
maturity in the industry. The main purpose of the Act is to
establish and implement a special tariff system in order to
catalyze the generation of renewable energy and related administrative matters. This Act needs to be read in conjunction with
the regulations and rules set out by the Ministry of Energy, Green
Technology and Water, which has been conferred with the
powers to regulate the new tariff system
