What is the green stack number for biomass in Hong Kong?

The topography of Hong Kong includes a mountainous terrain with very limited flatland and is not suitable for crop plantation development. Therefore, there is no forestry in this region and Hong Kong does not have a big agriculture industry. As a result, biomass is very limited with the exception of municipal organic waste.


In 2000, only 34,000 metric tons of oil equivalent energy was consumed by biomass, a very small percentage of the overall energy consumption for that year (0.27 percent). A very reasonable assumption is that the level of biomass in Hong Kong has remained the same since 2000. 


Thus, the calculation is as follows: (48 toe/1 year)(42 GJ/1 toe)(1,000,000 kJ/1 GJ)(1 year/365 days)(1 day/24 hours)(1 hour/60 minutes)(1 min/60 seconds)=63.9 kW


Converting this number in power per capita per day is approximately 0.0002 kWh/person/day.
