Renewable Energy Questions and Answers – Classification of Energy Resources

Renewable Energy MCQ Question

  1. Based on usability, Energy Resources are classified into _
    a) primary, secondary and tertiary resources
    b) primary and secondary resources
    c) primary, secondary, intermediate and tertiary resources
    d) primary, intermediate and secondary resources

Answer: d
Explanation: On the basis of usability, Energy Resources are classified into Primary, Intermediate and Secondary Resources. Primary Resources are present in nature prior to human interference or modification. Intermediate Resources are obtained from primary resources after one or more stages of transformation while Secondary Resources are the form of energy that is finally supplied to the consumer for utilization in Renewable Energy MCQ

  1. Which of the following is not a type of primary resource?
    a) Crude Oil
    b) Coal
    c) Hydrogen Energy
    d) Sunlight

Answer: c
Explanation: Hydrogen is mainly obtained from Fossil Fuels, which are primary sources of energy. Therefore, Hydrogen energy is a secondary source of energy. Crude Oil, Coal, and Sunlight are the primary source of energy since they can be directly obtained from nature.

  1. The ratio of energy received from a raw energy source to energy spent to obtain the raw energy source is called as _
    a) consumption ratio
    b) fuel ratio
    c) energy yield ratio
    d) joule ratio

Answer: c
Explanation: The ratio of the energy provided by a system (like Wind Energy Conversion Systems) over its lifetime to the energy required to make it is called its energy yield ratio.

  1. Energy Resources which are being used for many decades are known as _
    a) conventional energy sources
    b) non-conventional energy sources
    c) primary energy sources
    d) fuel cells

Answer: a
Explanation: Conventional sources of energy are those sources that are being used traditionally for a long time i.e. coal, petroleum, firewood, etc. Non-conventional sources are relatively new in terms of utilization.

  1. A new renewable energy system is designed to harvest energy from wind. The total energy required to build the system is 240 kJ. The energy yield ratio of the system is 14:3. The total energy provided by the system over its lifetime is _
    a) 18,000 kJ
    b) 54,000 kJ
    c) 1,120 kJ
    d) 2,258 kJ

Answer: c
Explanation: We know that the energy yield ratio (Ey) of a system is given by
Ey = (\frac{E_s}{E_r})
Where Es = Energy supplied by the system over its lifetime
And, Er = Energy required to build the system
Therefore, Ey = (\frac{Es}{240} = \frac{14}{3})
Or, Es = 240 x (\frac{14}{3})
Or, Es = 1120 kJ.

Renewable Energy MCQ – Advantages and Disadvantages of Conventional Energy Sources

  1. Conventional Energy Sources are cheaper than Non-Conventional Sources.
    a) True
    b) False

Answer: a
Explanation: At present Conventional Energy Sources are cheaper than Non-Conventional sources. Since the Non-Conventional sources are relatively new in terms of usage, the technology for harnessing energy from these sources is not well developed. The cost/kWh of electrical energy obtained from different conventional sources are as follows:
Coal- 1.65 ₹/kWh
Diesel- 3.00 ₹/kWh
Hydropower- 1.00 ₹/kWh
Nuclear – 1.20 ₹/kWh
which is less than the cost/kWh of the non-conventional sources.

9.Most of the Renewable energy sources are __
a) location-specific
b) universally available
c) highly efficient
d) polluting

Answer: a
Explanation: One of the major limitations of renewable sources is that they are location specific. States without rivers can’t have hydropower dams, and states with wind speed less than 23km/hr at 50 m height can’t have wind energy plants. Renewable energy sources are not universally available due to their location specificness. They have low efficiency due to their dilute nature. Most of the Renewable energy sources do not require any fuel and hence cause minimum to low pollution.
