1. Introduction to Singapore
Singapore is a small but densely populated (5.07 million people with 7,022 people per sq
km)) country with no natural resources, a high level of GDP ($AUD77,000 pa.) and a high level
of wealth (rated fourth in the world). Most of the current energy sources are external to the land
mass which is only 710 sq km. (ref 2) This essay analyzes likely future energy options for
Singapore for the century beyond this one.
1.1 Energy Challenges for Singapore
Singapore’s challenges are a complete lack of natural mineral resources, a lack of space for
large scale alternative sources (such as biomass crops or large solar farms), a very densely
populated island (currently the second most densely populated place on earth), a high level of
electricity consumption (41,800 GWh in 2009 – equivalent to 8.24 MWh per capita pa –
however only 7.085 GWh are used for domestic consumption – this is equivalent to 1.4 MWh
per capita pa) and a first world standard of living and industrial development that will not
readily accept a lack of energy (ref 3).
The Singapore Ministry of Trade and Investment stated in 2009: “we remain vulnerable to a
number of supply risks, including insufficient investments in production capacity by energy
producers, and events such as geopolitical conflicts, social unrest, terrorism, accidents and
natural disasters that might cause a temporary disruption in supply. The continued growth of our
economy can also be undermined by rising energy prices since our energy costs are fully
exposed to global movements in oil and gas prices” (Ref 5 Pg 17).

1.2 Singapore’s Advantages
Singapore has considerable financial resources, an uncorrupted totalitarian government with
centralized control, a strong public transport network, an effective civil service and a compliant
populace. These factors will allow the introduction of alternatives that might be unpopular in
less strictly controlled societies. The high population density and lack of natural resources and
space will naturally favor certain technologies against others. The closeness of less advantaged
neighbors such as Indonesia and Malaysia is an advantage in that some alternatives could be
developed offshore and funded by Singapore to both countries advantage.
The government recognizes these challenges; “As a small country with limited natural and
energy resources, we are mindful of the impact that an energy supply disruption could have on
our economy and society. The use of energy is also closely linked to environmental concerns
over air pollution and greenhouse gas emissions.“ (Ref 5)

1.4 Statistical Analysis
The tables above show that Singapore is a growing population with an increasing dependence
on energy as it develops. This needs is constant and disaster would arise should energy not be
available.

2. Singapore Current Energy Needs
Among the three most widely used international databases on energy, namely the EIA, BP
and the IEA, there is a large disparity on Singapore’s energy intensity. The Singapore Ministry
of Trade and Investment has determined that IEA’s data on Singapore’s energy intensity is the
most accurate of the three sources, as it had taken out marine bunkers from its calculation of
energy consumption. The ministry further found that Singapore’s energy intensity is roughly on
par for an economy of its level of development.
Figure 4 - Singapore's energy consumption and intensity (from ref 18)
The US Energy Administration ranks Singapore as the worlds 37th highest consumer of
energy at 1.97 PJ, with an energy intensity of 10,490 BTU / 2005 USD (42nd highest in the
world) and CO2 emissions of 154 MM MT p.a. (32nd
in the world) (Ref 6).
The IEA shows Singapore as consuming just over 50 million tonnes of oil products in 2008 –
however once the trade of oil is removed this was 18,000 ktoe in 2008 (excluding electricity
generation).

The World Bank estimate for Singapore’s energy use is 5830.5 kg OE per capita – the World
Bank also notes Singapore as having no alternative sources of energy apart from Fossil fuel. In
comparison the World Bank estimate for Australia’s energy use per capita is 5888 kg OE –
almost exactly the same as Australia (Ref 12). The IEA states Singapore on a per capita basis
consumes 6000 kg OE per annum.
As an export-oriented economy, much of the energy used by Singapore’s industry is not to
make products for local consumption but rather products for export. Singapore’s industry sector
accounts for about half of Singapore’s total energy use, most of it in exporting industries such as
petroleum refining, petrochemical, pharmaceutical and wafer fabrication industries. Singapore is
one of the largest refining centres in the world and the three oil refineries account for about 20%
of Singapore’s total energy use. (ref 4).
Regardless of the dispute on Singapore’s energy intensity, the government is committed to
taking steps to reduce energy consumption. According to the Energy Efficient Singapore
website, Singapore’s energy intensity dropped by 15% from 1990 to 2005 and has been
decreasing steadily since 2002, likely due to the use of better and more efficient technology in
the power generation and other sectors (Ref10).
The trend on the chart below however highlights how serious Singapore’s needs for energy
are – consumption is rising and there is very little indication that this can be quickly moved away
from being a hydrocarbon based economy.

2.1 Singapore’ Current CO 2 Emissions
The main contribution to Singapore’s greenhouse gas (GHG) emissions is carbon dioxide
(COs) from the use of energy to meet development and human needs. Singapore’s methane
emissions are negligible, as Singapore has no agricultural or primary industry. Singapore also
incinerates all waste and the little methane emitted from the existing landfill is flared off.
Despite having an export-oriented, energy-intensive economy, Singapore’s CO2 intensity
(CO2 per dollar GDP at 2000 PPP prices) is below the world average, according to the
International Energy Agency (IEA). (Ref 4)
Singapore’s CO2 emissions in 2005 were 40 Mt, accounting for less than 0.2% of global CO2
emissions. (Ref 7)
The power generation sector is the single largest primary source of carbon dioxide emissions
in Singapore, accounting for 48% of carbon emissions in 2005, the industry sector accounts for
about 54% of Singapore's carbon, the transport sector in accounts for about 19% of greenhouse
gas emissions and buildings sector contributes about 16% of Singapore's greenhouse gas
emissions. Most of the electricity used by buildings in Singapore is for air-conditioning (40-
50%), mechanical ventilation (about 20%) and lighting (15-20%). (Ref 11 Pg 7). Domestics
households generate about 10% of GHG emissions.
The Singapore government’s key strategy to reduce greenhouse gas emissions is to be more
energy efficient. The Sustainable Development Blueprint from the Singapore government sets a

target to reduce energy intensity (per dollar GDP) by 20% from 2005 levels by 2020, and by
35% from 2005 levels by 2030 (ref 10).
(From Ref 7)

3. Singapore’s current energy uses and sources.
3.1 Electricity
The power generation sector accounts for about half of the total fuel consumption in
Singapore. This energy is used to generate electricity, which is then used to power homes and
industries (Ref 8).
About 76 per cent of Singapore’s electricity is generated using piped natural gas (PNG)
supplies from Malaysia and Indonesia. Apart from possible supply disruptions there are
concerns that Singapore’s neighbors will increasingly require gas for their own domestic needs.
Consequently, less would be available for export to Singapore and other countries in the region
(Ref 5 Pg 18).
This fuel mix is much less diversified compared to the global average. To diversify electrical
power feedstocks sources, Singapore is planning to import liquefied natural gas (LNG) by 2013
(Ref 5 Pg 6).

3.2 Transport
Singapore has a well developed public transport network that currently carries 63% of the
passenger transport load. This network is power by electricity (for trains) and diesel (for buses)
with a very small percentage of CNG powered buses. The government aims to increase the
public transport load to 70% by 2020 (Ref 5 Pg 9). There are no alternatives however for goods
transport which rely on diesel powered vehicles in the main. Motor cars are powered in the main
by petrol (diesel cars are taxed at a very high rate and are not popular). There are a small
percentage of vehicles converted to CNG (approximately 3000 out of a vehicle fleet of almost 1
million). The total mileage driven p.a. at an average of 50km per day (ref 9) equates to
approximately 18.2 billion km. At an assumed average consumption of 8km/l this equates to 2.3
billion liters of petrol p.a. (approximately 80 PJ p.a.).
3.3 Waste-to-Energy
Singapore is one of the few countries that incinerate almost all domestic waste to generate
power. This practice minimizes the amount of waste disposed in landfills and generates
electricity in the process. Since Singapore recycles or incinerates almost all its waste, the amount
of decomposable waste in the landfills is reduced. As such, Singapore’s landfills generate
negligible amounts of methane (which is also a GHG), unlike landfills in other countries.
Since 2000, Singapore’s waste-to-energy plants have been contributing about 2-3% of the
energy supply. At the moment, there are four waste-to-energy plants. In 2009 Singapore

completed a fifth plant when the new Keppel Seghers Tuas Waste-to- Energy Plant begun
operation (ref 11).

4. Possible Future Energy Sources for Singapore
Singapore is a city-state with limited natural resources. Due to spatial and geographical
constraints, Singapore has very little alternative energy sources beyond oil and gas. The island
nation lacks the natural prerequisites to tap hydropower or geothermal energy such as large water
bodies or large land masses. Based on current technology for wind energy, there is also little
scope due to low wind speeds (Ref 7 – Para 3.3).
Alternative energy sources that will be more applicable to Singapore in the future (besides
the existing waste-to-energy plants) include solar energy and bio-fuels, particularly for Solar PV
as Singapore is located only 2 degrees north of the equator and has a large number of sunlight
days. However these sources of renewable energy are not yet cost-competitive with conventional
fossil fuels. Singapore is thus almost completely reliant on fossil fuels to meet energy needs at
present (Ref 7 – Para 3.4).
Improvements in reducing petroleum dependency to date have occurred through increased
efficiencies; for example while power generation between 2000 and 2006, overall power
generation efficiency improved from 38 per cent to 44 per cent due to the switch from oil-fired
steam plants to combined cycle gas turbines (CCGTs) (ref 5 Pg 9).
An analysis of the currently available commercial alternatives and some “blue sky”
alternatives is shown below.

4.1 Biomass Fueled Electricity
The principle involved is the conversion of vegetative matter into energy via combusting and
using the generated heat for electricity generation via a steam turbine. Although Singapore now
generates an estimated 2-3% of its electricity from the burning of waste matter the scope of
expansion of this program is limited by the lack of land for biomass production. The only way
this could be altered is by the cheap biomass from neighboring or Indonesia for conversion into
electricity (and possibly export sales of the electricity back to Malaysia). In this case the CO2
emissions would be offset by the uptake of CO2 during the growth cycle of the biomass. There is
some precedent for this to occur in that Singapore imports cheap “dirty” water from Malaysia
and treats it before reselling it back to Malaysia at a much higher price.
The estimated Biomass required to replace 50% of electricity consumed at 2010 levels can be
calculated using the data from Assignment 2. In this case 52.2 tonnes per hour was required for
a 100MW generating capacity. Singapore currently has an electrical generating capacity of
12GW approx – to replace 50% of the petroleum products would required 6264 tonnes per hour
of biomass – this is equivalent to approximately 250 truck loads per hour. This is somewhat
unrealistic. If the Biomass could be converted into a higher energy density form offshore (in
Malaysia for example) or delivered by ship this may be more viable.
4.2 Wind
Singapore is a very small country located in a relatively calm part of the Malaysian
archipelago. There is little potential for large scale wind farms to be built – either onshore or
offshore (it should be noted that Singapore waters are a significant source of government revenue
as Singapore is rated as the worlds’ busiest or second busiest sea port – offshore wind farms
would disrupt this trade).

18
4.3 Wave/Tidal /Hydro
Similar to the objections for wind power there is little scope for Wave / Tidal or Hyrdo
power. Although Singapore has some inland water bodies, these are miniscule in comparison to
the Snowy River Scheme for example. The average tidal movement in Singapore is quite low
(40 cm) and there is limited space for large scale tidal or wave based generation systems
offshore.
4.4 Geothermal / Ocean thermal
Singapore is located on near the “ring of the fire” – the highly active series of volcanoes
located around the Pacific Rim. Singapore itself however is geologically stable and the
geothermal gradient is normal – the nearest faults that would bring hot magma close to the
surface are in Indonesia – over 1000km away.
4.5 Solar – Thermal
Solar – thermal power is (generally) the generation of electricity from steam generated by
large scale solar farms that reflect and intensify light onto a collection tube. The output of a
parabolic SEGS (Solar Electric Generating System) is a direct function of how much land area is
available. The SEGS system in the Mojave Desert (USA) occupies 6.5km2 to generate 75MW
(from solar only). Singapore’s total land area is 581.5 km2. To replace 50% of the 12GW
current capacity would require approximately 520 km2 of area – clearly not a feasible option as
the entire island would be occupied by the SEGS plant alone!
4.6 Solar PV
Solar PV is the generation of electricity from photovoltaic panels. These obviously need to
be placed where sunlight can reach them. The current efficiency of panels is approximately 5%
8/7/2019 UWA OGEG8513- Future Energy Final Essay
http://slidepdf.com/reader/full/uwa-ogeg8513-future-energy-final-essay 19/26
19
to 18% with 20% being mooted in the near future for the standard commercial silicon crystalline
cell. Assuming panels can be placed on top of buildings and other flat surfaces it may be
possible to cover 1/10th (58.1 km2, 5.81 x 107 m2) of Singapore with panels. This would
generate at peak sunlight periods (i.e. 168 W/m2
where η = 0.2) 1. 9 x 109
W (i.e. 1.9 GW).
However this “peak” would only occur for a few hours during maximum solar radiation (i.e.
noon) when there are no clouds or rain – the general assumption the author has worked with in
SE Asia is that “7 days of no sunlight capacity” are needed – in this case perhaps only 0.28 GW
are available overall.
This option clearly can decrease Singapore’s electrical generation dependence from fossil
fuels but cannot remove entirely the dependence.
4.7 Bio-Diesel / Bio-Ethanol
The techniques and issues here are similar to Biomass electricity generation. The feedstock
needs to be sourced from outside Singapore in very large quantities. There is a very small bio-
diesel plant in operation currently in Singapore – the feedstock is palm oil from Malaysia and
domestic waste oil. The economics are very dubious as the tax rebate not applied simply cancels
out the high cost of palm oil. Furthermore – presumably due to economics – two biodiesel plants
previously planned for completion in 2007 and 2010 have been cancelled although Nestoil plan
to complete a plant this year with a capacity of 800,000 tonnes that uses Palm Oil as a feedstock.
It should be noted that protests are arising over the use of Palm Oil as Palm Oil as a monoculture
has become responsible for large scale destruction of rainforests in Malaysia and Indonesia as
well as competing against food agriculture.

4.8 Nuclear Fission
The viability of building a nuclear powered electricity plant in Singapore is undoubtedly
difficult given the dense population, small Island size and difficulty of waste disposal. The
government has not ruled the possibility out however (Strait Times Dec 2008). The PM Lee
Hsien Loong was quoted in 2008 as saying; 'I would not say never, because if global warming is a
serious problem, if energy prices in the long term continue to rise, fuel prices continue to rise, and if you
are worried about a carbon tax on top of that, then you have to seriously consider nuclear.'
More recent studies has followed the same idea; “Singapore has no fossil fuels of its own, and is
an unfavourable site for renewable energy. At some point, the possibility of a nuclear power station in
Singapore will need to be examined” (Ref 20). The same study by the Institute of Engineers in
Singapore concluded that a good location for such a plant would be underground. A succinct
quotation explains the reasoning; Teller (1908-2002) a Hungarian-American theoretical physicist
who had been much engaged with the development of the hydrogen bomb, wrote (2001): “My
suggestion...is to place nuclear reactors 300 to 1000 feet [90 to 300 m] underground, in loose
earth. In such a location, neither accident nor earthquake could result in a considerable amount of
radioactivity’s being released on the surface.” He went on further to explain that underground
locations reduce the threat of terrorism and radioactive material threat.
Indonesia is a close neighbor to Singapore. Indonesia is actively considering nuclear power
as an option – particularly as the country has recently become a net importer of oil. Indonesia's
House of Representatives gave a green light to the government's plan to build nuclear plants in
March 2010 (Ref 21). It would be feasible for Singapore to tap into electricity supplied from
Indonesia via subsea power cables. In such a case the likelihood of an accident affecting
Singapore would be reduced.

21
4.9 Natural Gas (including CBM)
Singapore plans to build an LNG terminal in 2013. The import terminal, costing a total S$1.5
billion ($1.1 billion), will have a capacity of 3.5 million metric tons a year (ref 17). This fuel
will supplement the existing PLG arrangement from Malaysia and crucially will be able to
supply feedstock to replace the imports of crude oil used in Singapore’s refineries at Bukom
island in due course. The project will be funded by loans and equity from the Singapore
government, which took over the project last year because of the GFC.
BG Group Plc won a 20-year contract to provide the fuel to the import terminal starting in
2012. The initial demand will be 800,000 tons rising to 3 million tons in 2018.
4.9.1 Gas to Liquid
Singapore operates two large petroleum refineries (One in Jurong and the other on Bukom
Island) and associated petrochemical plants. Currently these rely on liquid crude feedstock to
produce petrol, diesel, Jet-fuel etc that are exported (to the region including Australia) and
consumed domestically. Converting these refineries to accept an LNG input for conversion of
gas to liquid (i.e. to supply ethanol or biobutanol for example) is an expensive proposition but
would allow Singapore to continue as a fuel supplier as well as maintaining a source of feedstock
for the countries petrochemical factories. The CO2 emissions from such a process will be a
factor and energy inputs will also be required.
4.10 Hydrogen Economy
Free hydrogen does not occur naturally in quantity, and thus it must be generated from some
other energy source by steam reformation of natural gas or another method. Hydrogen is
therefore an energy carrier (like electricity), not a primary energy source (like coal) (ref 19). All
8/7/2019 UWA OGEG8513- Future Energy Final Essay
http://slidepdf.com/reader/full/uwa-ogeg8513-future-energy-final-essay 22/26
22
free commercial hydrogen generated today is derived from natural gas via a steam process –
estimates of the energy loss in the process approximate 60%. Therefore Hydrogen on its own it
is not a renewable or alternative source of energy for Singapore. Even as a carrier it has
problems with leakage, flammability and energy density compared to petroleum.
4.11 Electric Vehicles
Singapore has a pilot electric vehicle program in place with 50 Mitsubishi i-MiEV vehicles
(ref 15). Given Singapore’s small size and dense population – along with typically short driving
distances (~50km per day), electric vehicles would appear to be an obvious solution to reducing
fossil fuel dependence. However given that at present ~97% of Singapore’s electricity is derived
from either PLG or Oil, electric vehicles alone are not the solution to removing dependence from
fossil fuels. It should also be kept in mind that there are forecasts of serious shortages of
Lithium and other metals required for battery production along with current shortages of
Neodymium – all of these will affect the economics and availability of electric cars in the future
(ref 16).

5.1 Summation of determinations
The government policy towards future energy planning is outlined in the following quote;
“Energy plays an indispensable role in our economy. Our energy policy must be designed to ensure that
the energy sector will be able to deliver reliable and affordable energy supplies to our population and
businesses. In view of the changing energy environment, we need to formulate a holistic framework for
energy policy. Such a national framework should be intelligent, flexible and forward-looking in order to
address the energy challenges, capitalise on the opportunities generated by the evolving energy
landscape, and to sustain our long-term economic growth.” (Singapore Ministry of Trade and
Investment – 2009) Ref 5
The author’s opinion is that Singapore is not such a difficult position as initially envisaged.
Natural gas supplies are forecast to last a considerably long time (6.6 quadrillion SCF current
estimated reserves with consumption currently at approx 120 trillion SCF) and provide a high
energy density “clean” source of electrical energy and possibly liquid hydrocarbon source via
GTL processes.
Other energy alternatives will become more attractive as the rising prices of crude and LNG
reduces the advantage of conventional energy sources to the market place. The Singapore
government is in both a financial and political situation where hard decisions can be made and
subsidizes provided for the development of alternatives both domestically and internationally. In
this final regard the closeness of neighbors that can provide energy are important, these
