Singapore households will pay
25 per cent less for their electricity bills from
January to March 2009. The Energy Market Authority (EMA) said because of the global downturn,
fuel oil prices have fallen by as much as 40 per cent. In July 2008, a barrel of fuel oil was
US$115. It fell to
US$63 in October 2008.
What sort of calculation or mathematical formula is this ?
When there is a price increase, it was instantly executed the next day.
When there is a price deduction it was delayed for two to three months ? WHY ?
