1. Which are non-exhaustible source of energy?

Correct Answer: Correct answer is: (B) Solar energy, wind energy, Biogas.

Exam Relevance: GRE, GATE, NEET, JEE

Difficulty: Easy

Concept notes: Non-exhaustible sources of energy, also known as renewable resources, are those that can be replenished naturally and are not depleted by use. Examples include solar energy, wind energy, and biogas.

Common Mistakes: A common mistake is to confuse fossil fuels and natural gas with renewable resources. Fossil fuels and natural gas are non-renewable because they take millions of years to form and are finite.

Explanations: Solar energy, wind energy, and biogas are non-exhaustible sources of energy because they are naturally replenished and do not deplete over time. Solar energy is derived from the sun, wind energy from the movement of air, and biogas from the decomposition of organic matter. These sources are sustainable and can be used continuously without depleting the resource.

Option Analysis:

Option A: Fossil fuel and natural gas are exhaustible sources of energy because they are finite and take millions of years to form. They are not renewable.
Option B: Solar energy, wind energy, and biogas are non-exhaustible sources of energy because they are naturally replenished and can be used continuously without depleting the resource.

Mnemonic: S.W.B. - Solar, Wind, Biogas

2. Select renewable source of energy amongst those given

Correct Answer: Correct answer is: (D) Wind.

Exam Relevance: AP Environmental Science, GRE, GATE, NEET

Difficulty: Easy

Concept notes: Renewable resources are those that can be replenished naturally within a human timescale. Wind is a renewable resource because it is generated by the movement of air, which is a continuous process driven by the sun and the Earth's rotation.

Common Mistakes: A common misunderstanding is that all natural resources are renewable. However, resources like coal, petroleum, and firewood are non-renewable because they take millions of years to form and cannot be replenished within a human timescale.

Explanations: Wind is a renewable source of energy because it is generated by the continuous movement of air, which is driven by the sun and the Earth's rotation. This process is ongoing and can be harnessed to generate electricity without depleting the resource.

Option Analysis:

Option A: Coal is a fossil fuel and is not renewable because it takes millions of years to form and cannot be replenished within a human timescale.
Option B: Petroleum is also a fossil fuel and is not renewable for the same reasons as coal.
Option C: Firewood is a renewable resource in the sense that trees can be replanted, but it is not as sustainable as wind energy because it involves cutting down trees, which can lead to deforestation if not managed properly.
Option D: Wind is a renewable resource because it is generated by the continuous movement of air, which is driven by the sun and the Earth's rotation.

Mnemonic: Wind is renewable, like the sun's shine.

3. Alternative sources of energy include .....

Correct Answer: Correct answer is: (D) All of the above.

Exam Relevance: AP Environmental Science, GRE, GATE, MCAT

Difficulty: Easy

Concept notes: Renewable resources are energy sources that can be replenished naturally in a short period of time. Solar power, wind power, and hydropower are all examples of renewable energy sources.

Common Mistakes: A common misunderstanding is that only one of these options is a renewable resource, when in fact all three are.

Explanations: Solar power harnesses energy from the sun, wind power captures energy from the movement of air, and hydropower uses the energy from flowing water. All three are sustainable and can be replenished naturally, making them renewable resources.

Option Analysis:

Option A: Solar Power is a renewable resource as it uses the sun's energy, which is constantly replenished.
Option B: Wind Power is a renewable resource as it uses the kinetic energy of wind, which is a natural and continuous process.
Option C: Hydropower is a renewable resource as it uses the energy from flowing water, which is replenished through the water cycle.
Option D: All of the above are correct as they are all renewable resources.

4. What is used to store energy from the sun on cloudy days or during the night time?

Correct Answer: Correct answer is: (C) A battery.

Exam Relevance: AP Environmental Science, GRE, GATE, NEET

Difficulty: Easy

Concept notes: Batteries are used to store energy from the sun on cloudy days or during the night time in solar energy systems.

Common Mistakes: A common misunderstanding is that a photovoltaic cell (D) can store energy, but it only converts sunlight into electricity.

Explanations: In solar energy systems, photovoltaic cells convert sunlight into electrical energy. However, this energy needs to be stored for use during periods when sunlight is not available, such as at night or on cloudy days. Batteries are used to store this electrical energy for later use. Other options like a furnace (A) or a generator (B) do not store energy from the sun; they are used for different purposes.

Option Analysis:

Option A: A furnace is used for heating and does not store solar energy.
Option B: A generator produces electricity from fuel and does not store solar energy.
Option C: A battery stores electrical energy for later use, making it suitable for storing solar energy.
Option D: A photovoltaic cell converts sunlight into electricity but does not store it.

Mnemonic: Battery = Backup for Tomorrow's Energy Yield

5. Is Biomass a renewable OR non-renewable energy resource?

Correct Answer: Correct answer is: (D) Renewable.

Exam Relevance: AP Environmental Science, GRE, GATE

Difficulty: Easy

Concept notes: Biomass is a renewable energy resource because it is derived from organic materials that can be replenished over time.

Common Mistakes: A common misunderstanding is that biomass is non-renewable because it involves burning organic materials, which can be confused with fossil fuels.

Explanations: Biomass is considered renewable because it is derived from organic materials such as plants, agricultural waste, and wood. These materials can be regrown and replenished over time, making biomass a sustainable energy source. Unlike fossil fuels, which take millions of years to form and are not replenished on a human timescale, biomass can be continuously produced and used.

Option Analysis:

Option A: Biomass is not non-renewable because it can be replenished over time.
Option B: Biomass is not neither renewable nor non-renewable; it is specifically renewable.
Option C: Biomass is not both renewable and non-renewable; it is specifically renewable.
Option D: Biomass is renewable because it can be replenished over time.
Option E: Biomass is not all of the above; it is specifically renewable.

6. What is an economic benefit of solar energy?

Correct Answer: Correct answer is: (A) Saves on electricity bills.

Exam Relevance: AP Environmental Science, GRE, GATE

Difficulty: Easy

Concept notes: Solar energy is a renewable resource that can significantly reduce electricity costs by generating power from sunlight.

Common Mistakes: A common misunderstanding is that solar energy systems are too expensive to install and do not provide a return on investment.

Explanations: Solar energy systems can reduce electricity bills because they generate power from sunlight, which is free and abundant. Once the initial installation cost is covered, the ongoing electricity costs are significantly reduced or eliminated, leading to savings over time.

Option Analysis:

Option A: Correct. Solar energy systems can save on electricity bills by reducing reliance on grid electricity.
Option B: Incorrect. Solar energy typically reduces energy costs rather than increases them.
Option C: Incorrect. Solar energy can create job opportunities in installation, maintenance, and manufacturing.
