Power crisis in Bangladesh and Solar Plant

Bangladesh is an agrarian country.To become a industrial country Bangladesh have to develop its power sector.According to the Report of the Task Forces on Bangladesh Development Strategies for the 1990s, as s of 1991, 73.1% of the total energy consumption comes from biomass fuel, such as agricultural residues, tree residues, fuel wood, and dung. The use of biomass is not only an ineffective means of energy generation, it is also extremely detrimental to the environment. For instance, the forest cover in Bangladesh has been reduced from 15.6% to 13.4% between 1973 and 1987. According to some reports, the present forest cover is less than 9%. The decrease in forest cover contributes, among other adverse affects on the environment, to the increase in flooding propensity.

To meet the energy demand in the future, further research and development of the nuclear energy will continue throughout the world. Many countries in North America and Europe heavily rely on nuclear energy. For example, France uses up to 75% of nuclear energy to meet the national demand. Canada, Germany, UK, Sweden, USA, and Japan also use a significant amount of energy generated by nuclear reactors. According to the Energy Information Administration, the USA produces about 15% of its electricity (477 billion kilowatt-hour) supply from 132 nuclear reactors. India produces about 2% of its electricity (5.5 billion kilowatt-hours) from nine nuclear reactors.

Although nuclear energy is very efficient, it is relatively costly. Also, there are some risks involved in safety procedures and disposal of waste materials generated in nuclear power plants. Occasional accidents can be dangerous.

Another solve of energy crisis is Solar energy.The energy resource in Bangladesh is not unlimited.Solar energy may be the best solution in this situation in Bangladesh.Solar Power Plants - indirectly generate electricity when the heat from solar thermal collectors is used to heat a fluid which produces steam that is used to power generator.The advantage of solar plant is that it is environment friendly and disadvantage is it is costly then any other power system.But solar power is unlimited. Solar energy production needs no fuel, high durability and reliability and being able to operate for prolonged periods without maintenance make it economical for all types of remote applications.
