From all sub-sectors, the energy demand will decline in 2009 and will rise again from 2010 and 2011. Then, it will gradually decline until 2014. This pattern is the same like total energy demand pattern due [...] completion of the harbour extension project, total cost saving will be 0.36% in 2009 compared to 2008. Then, it will rise to 0.54 % per year after the completion of harbour extension project. Table 7: Demand [...] tons/y in 2009. Due to the additional 40 households, the CO2 emission will increase from 2010 to 2011. Then, it will decline again from 2011 because of expansion of renewable energy mainly on the electricity
