Red River Delta region (around 60 TWh). The calculated energy yield of the former and
the latter is equal to the yearly energy supply for nearly 15 and over 13 million households,
respectively. Together the potential of both regions makes approximately half the potential
of the Mekong River Delta region (see Table
6
).
The Northern midlands and Mountain areas region is the fourth-largest producer
of rice residues, followed by the South East region and the Central Highlands that are
both the least producers (just above 13 TWh each) with their total energy potential of rice
residues more than 17 times smaller in comparison with the Mekong River Delta region.
Nevertheless, both regions could still theoretically supply around 5 million households
with energy from rice straw biomass and 500 thousand households with the energy capacity
from rice husks annually.
3.4.2. Energy Potential of Residual Sugarcane Biomass
Production of sugarcane in Vietnam is lower than paddy rice; however, the residual
biomass still has significant energy potential. A comparison of the results shows that the
energy yield of residues from rice is approximately 15 times higher than the total yield of
sugarcane residues. Table

below illustrates the availability and the energy potential of
sugarcane bagasse and sugarcane trash divided into regions of the country.
