Paragraph on Load Shedding
Paragraph Name : Load Shedding
Answer: Load shedding means the disruption of power supply due to extra load. That is to say, load shedding is to stop the supply of electricity when the the demand is more than the supply. Sometime the necessity of electricity surpasses the amount of its supply. At that time, the production is less than the actual demand. Then it becomes impossible to supply electricity to all areas due to the shortage. So the electricity supply authority stops supplying electricity for a short while to some areas by turns in order to bring a co- ordination between the supply and demand. As a result load shedding occurs to some areas. Load shedding causes a lot of problems. It occurs without any notice. So it disrupst running mills and factories. For that, the production is hampered. It causes harm to machineries. Emergency medical treatment in hospitals is badly affected. Computer users lose unsaved data. Study of students is greatly hampered and they suffer a lot. In a word all the activities related to electricity are hindered due to load shedding. To stop load shedding we have to set up more electricity plants and produce more electricity to meet our increasing demand. We also have to stop the unnecessary use of electricity.
