As modern civilization works on luxurious life and electric power, these contribute a lot in luxury. To reduce pollution electric cars are planned and launched which will work by electricity as its fuel.
Some of the challenges that India's power sector faces today are _____________________.
Report Question
0%
Indias installed capacity to generate electricity is not sufficient to feed an annual economic growth of 7%
0%
State Electricity Boards incur losses which exceed Rs 500 billion.
0%
thermal power plants are facing shortage of raw material and coal supplies
0%
all of these
Explanation
India's power sector, the credit for 60% of the power production by thermal power plants is using coal as it's fuel. The main issue arises by the shortage of coal which also pollutes the environment. The losses are due to less formation of power which affects overall revenue. As the output is less, GDP is also affected directly.
Hence, D is the correct option.

Explanation
Non-commercial energy sources contains energy sources like cowdung, firewood, etc.
Mainly rural areas are highly dependent upon these sources, as it's provided by nature without any amount which is almost unlimited. But, it's bad for environment, burning of these fuel causes air pollution.
______ sources of energy are generally exhaustible, ______ sources are generally renewable.
Report Question
0%
Noncommercial, commercial
0%
Commercial, noncommercial
0%
Conventional, non conventional
0%
Non conventional, conventional
Explanation
Commercial sources are exhaustible like coal
, petroleum and electricity are considered
as the conventional source of energy. As these are the natural components which are there in the nature in little amount and can't be used again and again. These are only be used for once.
Other side, firewood, cow dung are non-commercial as they're are free of cost available with no limitations.
Hence, B is the correct option.
