A non-renewable resource is a natural resource that cannot be produced, re-grown, regenerated, or reused on a scale which can sustain its consumption rate. These resources often exist in a fixed amount, or are consumed much faster than nature can recreate them. Fossil fuel (such as coal, petroleum and natural gas) is an example.
- A non-renewable resource is always drawn down with anabolic processes that use up energy.
- Singapore has very limited non renewable resources. The economy is dependent on oil and natural gas imports.
- Singapore took a conscious decision to move from fuel oil to natural gas in 2001.Currently natural gas accounts for 80 per cent of the electricity generation.
In Singapore electricity is generated from:
- Natural Gas: 76 per cent
- Fuel Oil: 22 per cent
- Refuse: 2 per cent
- Diesel: 0.3 per cent
The Singapore government plans to bring in liquefied natural gas (LNG) to improve fuel mix and diversify gas sources. Liquefied Natural Gas (LNG) is natural gas that is stored and transported in liquid form at atmospheric pressure and at a temperature of minus 160oC. Like the natural gas that is delivered by pipeline to customers, it consists mainly of methane (CH4).
The Government has plans to construct a LNG terminal by 2012.The terminal is expected to meet initial demands of up to 3 million tones.
