Energy Resources and Storage Questions

Multiple choice physics work, energy and power forms of energy and energy conservation energy for everything forms of energy

Geothermal energy is feasible in regions that

  1. Are near the sea

  2. Have thermal plants

  3. Have coal mines

  4. Are over hot spots in the crust
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Geothermal energy relies on heat from the Earth's interior. Regions over hot spots in the crust, where magma is relatively close to the surface, are ideal for tapping into this heat.

  2. Molasses

  3. Pressmud

  4. Ethanol
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation
Bagasse
Bagasse is a fibrous material that remains after the juice is extracted from the sugar cane. It is used in the thermal power plant as fuel for production of power. Dry bagasse has calorific value of around 4600 Kcal/kg.
Multiple choice geography international development international development and world population and its impact on resources population growth and impact on resources reproductive health in humans

About ______ of the world's commercial energy comes from non-renewable fossil fuels.

  1. 50%

  2. 60%

  3. 70%

  4. 80%
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Most of our energy is derived from non-renewable sources. 80% of the world's commercial energy comes from fossil fuels i.e oil, coal and natural gas. As non-renewable resources, their use is clearly unsustainable. While these resources will still exist in the ground for many years, both the financial and energy costs of bringing them to market will become increasingly prohibitive as their supplies dwindle.

Multiple choice economics sustainable development with equity liberalisation objectives of economic planning in india need for sustainable development introduction to social movements and its types social movements

________ resources are those which can be used without the possibility of the resource becoming depleted or exhausted.

  1. Non-renewable

  2. Renewable

  3. Unlimited

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

A renewable resource is a natural resource which will replenish to replace the portion depleted by usage and consumption, either through natural reproduction or other recurring processes in a finite amount of time in a human time scale. Renewable resources include biomass energy such as ethanol, hydropower, geothermal power, wind energy, and solar energy. Biomass refers to organic material from plants or animals. This includes wood, sewage, and ethanol (which comes from corn or other plants).

Which of the following is an example of non-renewable resource?

  1. Petroleum

  2. Wind

  3. Solar energy

  4. Fossil fuel
Reveal answer Fill a bubble to check yourself
A,D Correct answer
Explanation
Non-renewable resources are those which get exhausted with extraction and use, for example, fossil fuel and petroleum. Wind and solar energy are renewable resources.
Multiple choice commercial applications management of natural resources unequal distribution of resources protecting our environment rules are for everyone

Bioenergy is the energy obtained from

  1. Coal

  2. Natural gas

  3. Biomass

  4. Petroleum
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation
Biomass is the amount of organic matter present in an organism. It is the stored form of energy in an organism. Biomass is used to produce bioenergy. Biomass can be of various types such as woods, crops, landfill gas etc. Biomass can be converted to various forms to produce biofuels, biogas etc. Highest amount of biomass is present in plants as they trap solar energy and convert it into mechanical energy in the form of stored food. 
So, the correct answer is 'Biomass'.

Both power and manure are provided by

  1. Petrocrops

  2. Nuclear plants

  3. Biogas

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

Biogas typically refers to a mixture of different gases produced by the breakdown of organic matter in the absence of oxygen. Biogas can be produced from raw materials such as agricultural waste, manure, municipal waste, plant material, sewage, green waste or food waste. It is a renewable energy source.
Biogas can be produced by anaerobic digestion with anaerobic bacteria, which digest material inside a closed system, or fermentation of biodegradable materials.
