Non Conventional Sources Of Energy Trivia Quiz

1.

Geothermal energy depends on
- A.
  
  Sun
- B.
  
  Wind
- C.
  
  Heat
- D.
  
  Waves
Correct Answer
C. Heat

Explanation
Geothermal energy is generated from the heat within the Earth's core. This heat is produced by the radioactive decay of minerals and the residual heat from the planet's formation. It is harnessed by drilling deep into the Earth's crust and extracting the hot water or steam to generate electricity. Unlike solar, wind, or wave energy, geothermal energy is not dependent on external factors like the Sun or wind, but rather on the Earth's internal heat.

Non conventional energy refers to
- A.
  
  Energy that causes lot of expenditure but is profitable
- B.
  
  Energy that is non renuable
- C.
  
  Energy that is used by majority of population
- D.
  
  Energy that is safe, renuable and do not cause heavy expenditure
Correct Answer
D. Energy that is safe, renuable and do not cause heavy expenditure

Explanation
Non-conventional energy refers to energy sources that are safe, renewable, and do not cause heavy expenditure. This means that these energy sources are sustainable and can be used without depleting natural resources. Additionally, they are safe for the environment and do not contribute to pollution or other negative impacts. Furthermore, they are cost-effective and do not require significant financial investment or expenses.

Biogas is prepared by bacteria .
- A.
  
  True
- B.
  
  False
Correct Answer
A. True

Explanation
Biogas is indeed prepared by bacteria. It is a type of gas that is produced through the breakdown of organic matter by bacteria in the absence of oxygen. This process, known as anaerobic digestion, occurs in biogas plants or digesters, where organic waste such as animal manure, agricultural residues, or sewage is fermented by bacteria. The bacteria break down the organic matter and produce biogas, which is primarily composed of methane and carbon dioxide. Therefore, the statement "Biogas is prepared by bacteria" is true.

Identify the picture
- A.
  
  Wind energy
- B.
  
  Solar energy
- C.
  
  Biogas
- D.
  
  Tidal energy
Correct Answer
C. Biogas

Explanation
The correct answer is Biogas because the picture represents a process in which organic waste materials such as food scraps and animal manure are broken down by bacteria in an anaerobic environment to produce methane gas, which can be used as a source of energy. Biogas is a renewable energy source that can be used for heating, electricity generation, and even as a fuel for vehicles.

From the above presentation we can infer that ___________ energy can be the most powerful.
- A.
  
  Solar energy
- B.
  
  Geothermal energy
- C.
  
  Biogas
- D.
  
  Tidal energy
Correct Answer
A. Solar energy

Explanation
Based on the information provided in the presentation, it can be inferred that solar energy can be the most powerful. The other options listed, geothermal energy, biogas, and tidal energy, are not mentioned or compared in terms of their power. Therefore, solar energy is the only option that can be inferred as the most powerful based on the given information.

Photovoltaic cells convert heat into electricity
- A.
  
  True
- B.
  
  False
Correct Answer
B. False

Explanation
Photovoltaic cells actually convert sunlight directly into electricity, not heat. This process is called the photovoltaic effect, where the cells use semiconductors to absorb photons from sunlight and generate an electric current. Therefore, the given statement is false.

In which of the following source of energy turbines are used
- A.
  
  Biogas and Geothermal energy
- B.
  
  Wind and Tidal energy
- C.
  
  Wind and Geothermal energy
- D.
  
  Solar and Tidal energy
Correct Answer
B. Wind and Tidal energy

Explanation
Turbines are used in the generation of electricity from wind and tidal energy. Wind turbines convert the kinetic energy of the wind into electrical energy, while tidal turbines harness the kinetic energy of tidal currents to produce electricity. Both wind and tidal energy are renewable sources of energy that can be harnessed using turbines to generate clean and sustainable power.

A region that uses Tidal energy
- A.
  
  Usa, Kenya and Japan
- B.
  
  India, France and Denmark
- C.
  
  Germany, Italy and China
- D.
  
  Australia, Canada and Chile
Correct Answer
D. Australia, Canada and Chile

Explanation
Australia, Canada, and Chile are all regions that use tidal energy. Tidal energy is a form of renewable energy that harnesses the power of ocean tides to generate electricity. These three countries have favorable geographical conditions, such as strong tidal currents and large tidal ranges, which make them suitable for tidal energy production. Additionally, they have invested in the development of tidal energy technologies and have implemented projects to harness this clean and sustainable source of energy.

Geothermal energy is used only for producing electricity
- A.
  
  True
- B.
  
  False
Correct Answer
B. False

Explanation
Geothermal energy is not only used for producing electricity but also for other purposes. It can be utilized for heating and cooling buildings, as well as for direct use in industries and agriculture. This renewable energy source harnesses the heat from the Earth's core and can be accessed through geothermal power plants or geothermal heat pumps. Therefore, the statement that geothermal energy is used only for producing electricity is false.

Wind energy can be used for
- A.
  
  Lighting
- B.
  
  Cooling
- C.
  
  Crushing grains
- D.
  
  None of these
Correct Answer
D. None of these

Explanation
Wind energy can be used for various purposes such as generating electricity, pumping water, or powering machinery. However, the options provided in the question do not include any of these uses. Therefore, the correct answer is "none of these" because none of the options accurately represent the potential uses of wind energy.
