Singapore pilot project
> Island’s generation mix is exclusively dependent on fossil fuels:
> 70% of the electricity is generated through burning heavy fuel oil,
> 30% through burning gas.
> The energy mix is considered as inappropriate for the energy independence of the
city state, as it exposes Singapore to volatility on the oil market.
> The same dependency happens in many islands
