PULAU Ubin could be powered by the sun, wind and even waste in a year or two, when it becomes a test-bed for clean-energy technologies.
An intelligent power grid will be set up on the island - to harness electricity from a variety of renewable power sources, and then regulate the flow of the power generated. A smart grid gets around the uncertainty of relying on one source of energy, which can make power supply patchy if, say, the wind dies down.
The Energy Market Authority (EMA) is calling for clean-energy companies to propose plans for such a grid.
