Environmental impact of alternative fuel mix in electricity generation in Malaysia

摘要

The Fuel Diversification Strategy was incorporated into the Malaysian National Energy Policy in order to achieve a more balanced consumption of fuel, namely gas, hydro, coal and petroleum. The objective of this paper is to evaluate changes in CO_2, SO_2 and NO_x emission due to changes in the fuel mix specified in the Fuel Diversification Strategy. Using the environmental extended Leontiefs input-output framework it was found that the fuel mix as envisioned by the Fuel Diversification Strategy generates higher CO_2, SO_2 and NO_x emissions. As such, to ensure a sustainable energy policy, the proposed fuel mix must be accompanied by efficiency gain so that the negative impact on the environment could be mitigated.
