Singapore's
Sustainable
Energy Story
Low-carbon energy deployment strategies and challenges.

EING A SMALL, RESOURCE-CONSTRAINED
country, Singapore has been dependent on
the import of energy products, such as coal,
petroleum, natural gas, etc., since its independence.
Specifically, it has relied on natural
gas, which is the cleanest form of fossil fuel, for several
years. In the past, the natural gas supply came from
the neighboring countries of Indonesia and
Malaysia through pipelines. However, the
construction of the Singapore Liquefied
Natural Gas Terminal in 2013
allowed Singapore to import and
store liquefied natural gas from
many different countries and
sources, thus broadening its
natural gas supply options.
A four-switch approach (see
Figure 1) was presented
with the aim of having a
future where energy is sustainable,
reliable, affordable,
and produced and consumed
efficiently. The four switches
mentioned are as follows:
x Natural gas: Currently,
almost 95% of the electricity is

generated using natural gas, and, in the near future, it
will continue to be a dominant fuel for Singapore as
other sources of energy are developed.
x Solar: With Singapore's commitment to climate
change mitigation, it would be a viable option for Singapore
to opt for renewable sources of energy as it
slowly reduces its dependence on natural gas for
electricity generation. Currently, solar energy
is considered one of the most feasible
renewable energy sources for
Singapore. Other renewable
energy sources, such as hydro
and wind energy sources,
are not readily available in
Singapore due to the lack
of sustainable sources
of water flow and high
wind speeds. Also, the
water surrounding Singapore
is constantly occupied
by anchorages and
shipping lanes, which
reduces the amount of
space available to deploy
tidal power generation. Hence,
with solar being the most promising
option, Singapore's current goal
is to generate at least 2 GW peak (GWp)
of solar energy by the year 2030.
