Energy Resources and Storage Questions

Multiple choice physics sources of energy non-conventional sources of energy electric energy generation and environment renewable and non-renewable energy

The source of energy of the hot water spring is geothermal energy.           

  1. True

  2. False

  3. Ambiguous

  4. Data insufficient
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Geothermal energy is the heat from the Earth. It's clean and sustainable. Resources of geothermal energy range from the shallow ground to hot water and hot rock found a few miles beneath the Earth's surface, and down even deeper to the extremely high temperatures of molten rock called magma.

The non-renewable source of energy amongst the following is :

  1. wind energy

  2. hydel energy

  3. solar energy

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

Answer is D.

A non-renewable resource (also called a finite resource) is a resource that does not renew itself at a sufficient rate for sustainable economic extraction in meaningful human time-frames. An example is carbon-based, organically-derived fuel. The original organic material, with the aid of heat and pressure, becomes a fuel such as oil or gas. Earth minerals and metal ores, fossil fuels (such as coal, petroleum, and natural gas), nuclear fuels, and groundwater in certain aquifers are all non-renewable resources.
Natural resources such as coal, petroleum (crude oil) and natural gas take thousands of years to form naturally and cannot be replaced as fast as they are being consumed. Eventually it is considered that fossil-based resources will become too costly to harvest and humanity will need to shift its reliance to other sources of energy. 
Hence, fossil fuels are non-renewable resources.

Define renewable sources of energy.

  1. A source whose energy supplied can be renewed is called renewable source of energy.

  2. A source of energy which will exhaust in future is called renewable source of energy.

  3. A natural source providing us energy which takes long time to replenish.

  4. A source of energy which causes environmental pollution is called renewable source of energy.

A Correct answer
Explanation

A natural source of energy that can provide us energy continuously without being exhausted is called a renewable source of energy.

Which of the following is not ultimately derived from the Sun's energy?

  1. geothermal energy

  2. wind energy

  3. nuclear energy

  4. bio-mass.
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

All the sources of energy are directly or indirectly derived from the ultimate source of energy. i.e. Sun, except for the nuclear energy. Nuclear energy is derived from the molecules of the radioactive elements.

Multiple choice physics towards green energy non-conventional sources of energy electric energy generation and environment renewable and non-renewable energy

Of the following, renewable source of energy is

  1. Wood

  2. Petroleum

  3. Natural gas

  4. Uranium
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Wood is a renewable source of energy because it can be replenished by planting new trees. Petroleum, natural gas, and uranium are finite fossil or mineral fuels that cannot be replaced on a human timescale.

Multiple choice physics towards green energy non-conventional sources of energy electric energy generation and environment renewable and non-renewable energy

The sources of energy which are being produced continuously in nature and are inexhaustible, are called

  1. Conventional sources

  2. Non-renewable sources

  3. Non-conventional sources

  4. None of these
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Sources of energy that are inexhaustible and produced continuously in nature are generally classified as non-conventional or renewable sources. Conventional sources like coal and petroleum are finite and exhaustible.

Among the following the sources of energy for which the sun is not a chief source of energy is ________.

  1. Hydroelectric power plant

  2. Ocean thermal energy conversion (OTEC).

  3. Tidal energy

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

Hydroelectric power depends on the water cycle driven by solar energy, OTEC relies on ocean temperature differences caused by solar heating, and biomass grows via photosynthesis driven by sunlight. Tidal energy, however, is driven primarily by the gravitational pull of the moon and the sun, making tidal energy distinct as it is not fundamentally powered by solar radiation.

Biomass based energy can be obtained from :

  1. direct burning of wood, agricultural residue etc.

  2. biomass may be converted in to some other form of fuel which can release energy.
  3. bacterial decomposition of organic matters like cow dung, agricultural wastes, human excreta etc. in presence of water in absence of air, a mixture of $CH _4, CO _2, H _2, H _2S $ etc.

  4. burning of industrial waste.
Reveal answer Fill a bubble to check yourself
A,B,C Correct answer
Explanation

A biofuel is a fuel that is produced through contemporary biological processes, such as agriculture and anaerobic digestion, rather than a fuel produced by geological processes such as those involved in the formation of fossil fuels, such as coal and petroleum, from prehistoric biological matter. Biofuels can be derived directly from plants, or indirectly from agricultural, commercial, domestic, and/or industrial wastes. Renewable biofuels generally involve contemporary carbon fixation, such as those that occur in plants or microalgae through the process of photosynthesis. Other renewable biofuels are made through the use or conversion of biomass (referring to recently living organisms, most often referring to plants or plant-derived materials). This biomass can be converted to convenient energy-containing substances in three different ways: thermal conversion, chemical conversion, and biochemical conversion. This biomass conversion can result in fuel in solid, liquid, or gas form. This new biomass can also be used directly for biofuels.
