Rm. Shrestha et al., ENVIRONMENTAL EMISSION MITIGATION POTENTIAL OF EFFICIENT ELECTRICAL APPLIANCES IN SRI-LANKA, International journal of energy research, 22(10), 1998, pp. 923-933
This study assesses the techno-economic potential of selected efficien
t demand-side appliances to mitigate emission of air pollutants from t
he power sector of Sri Lanka. The study shows that through the use of
the selected efficient appliances a total of about 38 646 GWh (i.e. 18
.5% of total electricity generation) and about 25.6% (29 541, 000 tons
), 34.2% (293,000 tons) and 34.6% (374,000 tons) of the total CO2, SO2
and NOx emission respectively could be avoided during 1997-2015 with
the use of the efficient appliances from the technical and national ec
onomic perspectives. The generation savings from utility and user pers
pectives and emission mitigation potential are, however, significantly
smaller as all the selected appliances are not found cost effective f
rom these perspectives. This is mainly because electricity prices in t
he commercial and industrial sectors exceed the corresponding long-run
marginal cost (LRMC) of electricity supply. (C) 1998 John Wiley & Son
