Which of the following is a challenge in power generation sector?
Report Question
0%
Inadequate generation
0%
Losses of electricity boards
0%
Less capacity utilisation
0%
All of these
Explanation
The following are the challenges faced by the power generation sector:
1. Inadequate generation of electricity: India is struggling to meet the surging demand for power. India's Central Electricity Authority anticipated, for 2017-18 fiscal year, the power deficit to be 0.6 percent.
2. Less capacity utilization: Capacity utilization is indicated by Plant Load Factor. In India, there is an under-utilization of the production capacity of thermal power stations. In 2018-19, PLF in India was nearly 61.07 percent. It means just 60 percent of electricity is available, the rest goes waste.
3. Transmission and distribution losses: In most states of the country, transmission and distribution losses are more than 20 percent. It may partly be due to our backward technology but largely due to pilferage involving the official staff.
4. Losses of electricity boards:
Electricity is distributed by State Electricity Boards.
Production and distribution of electricity in India is the near-monopoly of the government. At present, almost all the electricity boards are running into huge losses. They do not have funds to make payments for the electricity purchased by them.
Hence, D is the correct option.
Plant Load Factor =
Report Question
0%
Electricity generated x Production capacity
0%
Electricity generated / Production capacity
0%
Electricity generated + Production capacity
0%
Electricity generated - Production capacity
Explanation
Production capacity utilization of a power plant is indicated by Plant Load Factor.
Plant Load Factor = Electricity generated / Production capacity.
Hence, B is the correct option.

It you live in an overcrowded and poorly ventilated house, it is possible that you may suffer from which of the following diseases?
Report Question
0%
Cancer
0%
AIDS
0%
Air borne diseases
0%
Cholera
Explanation
If you live in an overcrowded and poorly ventilated house, it is possible that you may suffer from some air borne diseases. The chances of spreading the air borne diseases are more in the crowded and poorly ventilated area. This is because, in such areas, the person infected with some disease easily spreads the infectious droplets through breathing and sneezing. These infected droplets are inhaled by the healthy person who can become infected. In addition, if the house is not properly ventilated, the infectious droplets keep on circulating in the closed area and hence more and more people can become infected with the disease.
