Energy crisis is one of the most serious threats towards the sustainability
of human kinds and civilization. Although industrial revolution
has changed the world to its sophisticated edge, excessive
dependent on fossil fuels as the main source of energy has leads
to the diminishing of this non-renewable supply. Furthermore, demand
for petroleum-derived fuels is not slowing down but instead
increases substantially over the past few decades. Malaysia is not
spared from this scenario as energy consumption has escalated to
a new height of 44,268 ktoe in the year 2007. On the other hand, extreme
usage of fossil fuels brings another looming disaster to human
being and the mother earth, namely global warming. In
Malaysia, transportation sector contributes significantly to the total
CO2 emission with more than 19% of the total emission. Although it
has a relatively small population, average emission in Malaysia was
reported to be 7.5 tons of CO2 per capita according to UNDP report
(2008). In fact, its CO2 emission has been increasing steadily from
1994 to 2004 with an increment of 221% during this period. Hence,
an indigenous, affordable and clean source of energy has become a
high priority in Malaysia to surmount the issue of energy security
and sustainability of human development.
