Non-Conventional Energy Sources and Energy Crisis
Test your knowledge of renewable energy sources including solar, nuclear, geothermal, tidal, and ocean energy, along with energy crisis concepts.
Questions
How is tidal energy generated?
- Due to the difference in water levels in sea and rivers
- Due to fast blowing winds
- Due to high and low tides
- Both (1) and (3)
Which of the following is not an advantage of nuclear energy?
- Nuclear fuel can be used for a long time.
- It can cause very serious health problems in case of an accident.
- Even a small amount of nuclear fuel has the ability to generate very high amount of energy.
- It helps to reduce the dependence on fossil fuels.
Which of the following mirrors can be used to focus sunlight in a solar cooker?
- Concave
- Convex
- Plane
- Any of them
The most powerful energy source, if utilised properly, is
- biomass energy
- wind energy
- nuclear energy
- geothermal energy
Which of the following is not an energy form obtained from the sea?
- Tidal energy
- Ocean thermal energy
- Hydro energy
- Wave energy
How is geothermal energy influenced by the sun?
- Geothermal energy increases due to an increase in the intensity of the sun's rays.
- Geothermal energy decreases due to decrease in the intensity of the sun's rays.
- Geothermal energy converts nuclear energy to thermal energy.
- Geothermal energy is not influenced by the sun.
In a nuclear fission reaction,
- heavier nuclei combine to give a heavier nucleus and release of energy
- heavier nucleus breaks up into lighter nuclei and release of energy
- lighter nuclei combine to give heavier nucleus and release of energy
- lighter nucleus breaks up into even lighter nuclei and release of energy
Energy crisis can be solved by utilising
- geothermal energy
- nuclear energy
- solar energy
- All of the above
A major drawback of a nuclear power plant is that it

- is very costly to set up
- uses uranium which is available scarcely
- All of the above
Solar cooker can be used to cook food on a
- cloudy day
- sunny day
- stormy day
- rainy day
Geothermal energy is produced due to the
- geography of region
- climatic changes
- geological changes
- wind in that region
Which of the following is/are the drawback(s) of solar cell panel, inspite of being a good source of energy?
- It is costly to set up.
- It is a low power source.
- It is not compact in size.
- All of these.
We are facing an energy crisis because
- energy cannot be created
- energy cannot be destroyed
- energy changes from useful to useless form
- energy changes from useless to useful form
Which of the following energy sources is renewable?
- Fossil fuels
- Thermal power plant
- Hydropower plant
- Both (2) and (3)
