Question 1: Define a non-renewable energy resource and give two examples.

Answer: A non-renewable energy resource is a resource that cannot be replenished at a sustainable rate once depleted; examples include coal and oil.

Question 2: Describe the primary method used to extract natural gas from underground reserves.

Answer: Natural gas is primarily extracted through drilling wells into underground reservoirs and then bringing the gas to the surface for processing.

Question 3: Explain how the combustion of coal generates electricity.

Answer: Burning coal heats water to produce steam, which then drives turbines connected to generators, converting mechanical energy into electrical energy.

Question 4: Calculate the amount of energy (in joules) released when burning 1 kg of coal with an energy content of 24 MJ/kg.

Answer: Energy = mass × energy content = 1 kg × 24,000,000 J/kg = 24,000,000 J

Question 5: Identify one major environmental concern associated with the use of non-renewable energy resources.

Answer: One major concern is the emission of greenhouse gases, such as carbon dioxide, which contribute to climate change.

Question 6: Which of the following is a non-renewable energy resource? A) Solar power B) Wind energy C) Oil D) Geothermal energy

Answer:

Question 7: Fill in the blank: The process of converting fossil fuels into usable energy involves __________ and ________.

Answer: combustion, energy conversion

Question 8: Describe two safety precautions that should be taken when handling non-renewable fuels like coal or oil.

Answer: Safety precautions include wearing proper protective gear (gloves, masks), ensuring proper ventilation to prevent inhalation of toxic fumes, and following safety protocols during storage and combustion to prevent fires or explosions.

Question 9: Explain the concept of energy efficiency in the context of non-renewable energy power plants.

Answer: Energy efficiency refers to the ratio of useful electrical energy produced to the total energy input during fuel combustion; higher efficiency means less energy is wasted.

Question 10: Discuss one technological advancement that has improved the efficiency or safety of non-renewable energy extraction or use.

Answer: One advancement is the development of cleaner coal technologies, such as carbon capture and storage (CCS), which reduces greenhouse gas emissions from coal-fired power plants, improving environmental safety and efficiency.

Question 11: Based on current trends, what is a likely future challenge for reliance on non-renewable energy sources?

Answer: A major future challenge is the depletion of finite resources and the need to transition to sustainable energy sources to prevent energy shortages and environmental damage.
