Energy is an important element of the socio-economic development of a country. The indigenous and renewable energy sources of Bangladesh are poor, and the country is heavily dependent on the imported fossil fuels. The combustion of fossil is has major pollution impacts on the environment, especially on the air environment. I this article, the sector wise and fuel wise energy consumption patterns and trends in Bangladesh in the period 1988-89 994-95 with projections upto 2010, have been analysed in details. In 1994-95, Bangladesh consumed 314 PJ energy on a total, among that natural gas consisted 48%, diesel oil 22%, crude oil 19% and other II % as fuel-wise, and power plant consumed 36%, oil refining 19%, transport 16%, residential 12%, industry 10%, others 7% as sector-wise. The sector-wised analysis shows that the rate of energy consumption is increasing day by day in most of the sectors with an average annual growth rate of about 6%, while fuel-wise trend scenarios show that the consumption of every fuel is also increasing with time except coal and residual oil whose consumption is decreasing.
Emission of pollutants from energy consumption is a major air pollution issue allover the world. In this article, an nation of SO2 and NOx emitted into the atmosphere as a result of fossil fuel consumption by various economic sectors in Bangladesh in the period 1988-89 to 1994-95 with projections upto 2010 has been performed and presented. Total SO2 and NOx emission in 1994-95 was 61,351 tones and 80,884 tones, respectively. The analysis of SO2/NOx emission with time shows an increasing trend for transport and power plant sectors, and decreasing trend for industrial sector. The biggest source of SO2/NOx pollution is the transport sector, which is followed by power plants. In case of fuel wise SO2/NOx emission, diesel oil is the largest SO2 emitter, whereas natural gas is the biggest NOx emitter. SO2/NOx emission from natural gas, diesel oil and gasoline shows an increasing trend, while SO2/NOx emission from coal is decreasing with time.
