| Abstract | This study essentially assesses the energy planning and environmental implications of energy use, in general, biomass energy, in particular in Sri Lanka during 2000-2020. The first chapter presents a detailed explanation of the nature of problem and the objectives of the study. The second chapter is devoted to the literature review of the study and different energy and environmental models are taken into consideration. A separate chapter has provided for estimations of final energy demand for various sectors and sub-sectors. The study also considers the implications of emission reduction targets, which will be a crucial issue in the coming years even for the developing countries. Emission reduction targets of 5%, 10% and 15% have been considered. Finally, the study considers the potential mitigation options with utilization of biomass energy technologies. One of the main findings from the study is that the primary energy requirement in 2020 under the business as usual case, would be in the range of 586 PJ to 670 PJ as compared to about 272 PJ in 2000. The requirements of petroleum energy is increased rapidly and will be around twice that of the base year while electricity requirement increases gradually during the first 10 years and after that in 2020, it will also reach around twice that of in 2000. Biomass consumption shows a gradual increment and will increase rapidly towards the end of year 2020, basically due to the utilization of biomass for electricity generation. Transport sector would be the largest contributor to total C02 emission in Sri Lanka in 2020 followed by industry and power sectors. Incremental cost of C02 abatement would be 12.03 US$/ ton-C02 at the emission reduction target of 5% while it would increase to 35.86 US$/ton-C02 at the higher reduction target of 10%. At emission reduction target of 15% incremental cost will go up to 79.3 US$/ ton-C02. Emission reduction targets seem to be quite influential for S02 and NOx emissions, as the cumulative reduction of S02 in 2020 at 5%, 10% and 15% reduction targets would be around 1.25%, 4.71 % and 6% respectively. Total cumulative NOx emission under ER5, ERlO and ER15 cases during 2000-2020 would be around 22, 35 and 38 thousand tons respectively, which means a reduction by 3.2%, 5.4% and 5.82% respectively from the total cumulative NOx emission in the base case. |
