Question : Non-commercial energy sources are often used for:
Option 1: Industrial production
Option 2: Transportation
Option 3: Cooking and heating
Option 4: Electricity generation
Correct Answer: Cooking and heating
Solution : The correct answer is (C) cooking and heating.
Non-commercial energy sources refer to traditional and often locally available sources of energy that are used primarily for household purposes in rural and low-income areas. These sources include biomass fuels such as firewood, agricultural residues, and animal dung, which are commonly used for cooking and providing heat in households. They are typically used in traditional stoves or open fires, especially in regions where access to commercial energy sources may be limited or unaffordable. Non-commercial energy sources are also used for small-scale localized electricity generation in some cases, but their primary usage is for cooking and heating needs.
Question : Which infrastructure sector focuses on the generation and distribution of electricity?
Option 1: Energy infrastructure
Option 2: Transportation infrastructure
Option 3: Telecommunication infrastructure
Option 4: Water infrastructure
Question : Assertion: Commercial energy sources, such as coal and natural gas, are extensively used for electricity generation and industrial purposes.
Reason: Commercial energy sources are readily available and have high energy density.
Option 1: Both assertion and reason are correct, and the reason is the correct explanation of the assertion.
Option 2: Both assertion and reason are correct, but the reason is not the correct explanation of the assertion.
Option 3: Assertion is correct, but the reason is incorrect.
Option 4: Assertion is incorrect, but the reason is correct.
Question : The term "grid parity" refers to:
Option 1: Equal distribution of energy resources
Option 2: The cost of renewable energy matching conventional energy
Option 3: A power outage in the electricity grid
Option 4: An efficient energy transmission system
