Energy Resources and Storage Questions

Multiple choice

Hydroelectric plant produces more electricity when

  1. temperature of water increases

  2. water is stored at a low height

  3. water is stored at a higher height

  4. electricity content of the water increases

  5. -
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

This is an incorrect answer. If the water is stored at a higher height, the potential energy of the water is more and hence, the kinetic energy of the water is also more. Thus, production of electricity is more.

Multiple choice

Gulf of Cambay and Gulf of Kutch are most attractive locations for generation of

  1. geothermal energy

  2. wind energy

  3. tidal energy

  4. solar energy
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

The most attractive locations are the Gulf of Cambay and the Gulf of Kutch on the west coast where the maximum tidal range is 11 m and 8 m with average tidal range of 6.77 m and 5.23 m, respectively. The Ganges Delta in the Sundarbans in West Bengal also has good locations for small scale tidal power development.

Multiple choice

Which of the following options is not a conventional source of energy?

  1. Cow-dung

  2. Wind

  3. Wood

  4. Agriculture wastes
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Conventional energy sources are those that have been traditionally used for centuries, like wood, agricultural waste, cow dung (biomass). Non-conventional sources are newer or renewable alternatives like wind, solar, tidal, geothermal. Wind is classified as non-conventional renewable energy.

Multiple choice

Find out the appropriate word and fill blank (i).

Directions: The following passage has some blanks, each of which has been numbered.

There are two ____ (i)____ sources of energy, renewable and non-renewable. ____(ii)____ electric power is a major energy source. This is electricity generated by turbines turned by water. Solar energy is energy ____(iii)____ from the sun. Sun is a very important energy source. Renewable energy sources are clean and ____ (iv)____. They can be ____ (v)____ too

  1. various

  2. different

  3. types

  4. many
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

'Different' is the correct word choice because the sentence contrasts two distinct categories of energy sources - renewable and non-renewable. While 'various,' 'types,' and 'many' are grammatically possible, they don't properly convey the contrast between the two categories. 'Different' emphasizes the distinction between these two types.

Multiple choice

Find out the appropriate word and fill blank (iii).

Directions: The following passage has some blanks, each of which has been numbered.

There are two ____ (i)____ sources of energy, renewable and non-renewable. ____(ii)____ electric power is a major energy source. This is electricity generated by turbines turned by water. Solar energy is energy ____(iii)____ from the sun. Sun is a very important energy source. Renewable energy sources are clean and ____ (iv)____. They can be ____ (v)____ too

  1. enabled

  2. given

  3. derived

  4. took
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

'Derived' is the correct verb meaning energy obtained or drawn from the sun. We say solar energy is derived from the sun. 'Given' is too passive - energy isn't simply given; it's extracted or obtained. 'Enabled' doesn't make sense in this context. 'Took' is incorrect grammar and meaning - we don't say energy is 'took' from a source.

Multiple choice

Find out the appropriate word and fill blank (ii).

Directions: The following passage has some blanks, each of which has been numbered.

There are two ____ (i)____ sources of energy, renewable and non-renewable. ____(ii)____ electric power is a major energy source. This is electricity generated by turbines turned by water. Solar energy is energy ____(iii)____ from the sun. Sun is a very important energy source. Renewable energy sources are clean and ____ (iv)____. They can be ____ (v)____ too

  1. Thermal

  2. Nuclear

  3. Hydro

  4. Solar
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

The passage describes electricity that is 'generated by turbines turned by water.' This is the definition of hydroelectric power, where flowing or falling water turns turbines to generate electricity. Thermal, nuclear, and solar power do not use water-driven turbines as their primary generation mechanism.

Multiple choice

Find out the appropriate word(s) and fill blank (iv).

Directions: The following passage has some blanks, each of which has been numbered.

There are two ____ (i)____ sources of energy, renewable and non-renewable. ____(ii)____ electric power is a major energy source. This is electricity generated by turbines turned by water. Solar energy is energy ____(iii)____ from the sun. Sun is a very important energy source. Renewable energy sources are clean and ____ (iv)____. They can be ____ (v)____ too

  1. clear

  2. non-polluting

  3. endless

  4. important
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

The sentence discusses renewable energy sources being 'clean and ____'. Since the context emphasizes environmental benefits, 'non-polluting' is the logical choice - it directly states that renewables don't produce harmful emissions or pollutants. While 'clear' and 'important' are positive, they don't complete the environmental comparison as effectively.

Multiple choice

Find out the appropriate word and fill blank (v).

Directions: The following passage has some blanks, each of which has been numbered.

There are two ____ (i)____ sources of energy, renewable and non-renewable. ____(ii)____ electric power is a major energy source. This is electricity generated by turbines turned by water. Solar energy is energy ____(iii)____ from the sun. Sun is a very important energy source. Renewable energy sources are clean and ____ (iv)____. They can be ____ (v)____ too

  1. consumed

  2. used

  3. generated

  4. replaced
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

The passage states that renewable energy sources 'can be ____ too.' Since the previous sentence describes them as 'clean and non-polluting,' the word 'replaced' makes the most sense - renewable sources can naturally replenish or be renewed (unlike finite coal or oil). 'Consumed,' 'used,' and 'generated' don't capture the essential renewable quality.

Multiple choice

Which of the following cannot be considered as an energy source?

  1. Generator

  2. Transformer

  3. Solar cell

  4. Rheostat

  5. Battery
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Rheostat is the variable resistance, i.e. we can vary the value of resistor using rheostat. Rheostat is not energy source. It is used only to increase or decrease the given voltage value in lab experiments.

Multiple choice

Which of the following is a fossil fuel?

  1. Nuclear energy

  2. Wind

  3. Solar energy

  4. Natural gas

  5. Geothermal energy
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Natural gas is formed with coal and petroleum from the dead remains of plants or animals.
