Question 1: Define 'renewable energy' and give two examples.

Answer: Renewable energy is energy from sources that are naturally replenished, such as wind and solar power.

Question 2: What is 'fossil fuel'? Name three types commonly used for energy generation.

Answer: Fossil fuels are non-renewable energy sources formed from ancient organic matter, including coal, oil, and natural gas.

Question 3: Explain 'energy security' in the context of resource management.

Answer: Energy security refers to the reliable and affordable supply of energy to meet a country's needs.

Question 4: Define 'carbon footprint' and its relevance to energy consumption.

Answer: A carbon footprint measures the total greenhouse gases emitted directly or indirectly by an individual, organization, or product, primarily from energy use.

Question 5: What is the significance of 'offshore oil extraction' in the UK?

Answer: Offshore oil extraction in the UK, particularly in the North Sea, has been a major source of domestic oil production, contributing to energy independence and economic revenue.

Question 1: Which country is the largest producer of wind energy in Europe?

Answer: Germany

Question 2: Name the major oil field located in the North Sea that has historically contributed significantly to the UK's oil production.

Answer: The Brent oil field

Question 3: Identify two advantages of renewable energy sources over fossil fuels.

Answer: They are sustainable and produce less greenhouse gas emissions.

Question 4: What does the term 'energy mix' refer to?

Answer: The combination of different energy sources used by a country to meet its energy needs.

Question 1: Based on the case study of the UK's energy supply, explain how the country has diversified its energy sources in response to declining North Sea oil production.

Answer: The UK has increased investment in renewable energy, such as wind and solar power, and imported natural gas to reduce reliance on diminishing North Sea oil reserves, thus enhancing energy security and sustainability.

Question 2: Identify two environmental impacts associated with offshore oil extraction in the North Sea.

Answer: Oil spills causing marine pollution and habitat disruption for marine species.

Question 3: Discuss the economic benefits and challenges of expanding renewable energy in the UK, based on the case study.

Answer: Benefits include reducing carbon emissions and creating jobs; challenges involve high initial costs, intermittency issues, and the need for technological development.

Question 1: Explain why offshore oil extraction is concentrated in the North Sea region.

Answer: The North Sea has rich oil reserves, advantageous geological formations, and existing infrastructure, making it a prime location for offshore extraction.

Question 2: Analyse the reasons for the global shift towards renewable energy sources.

Answer: Global concerns over climate change, finite nature of fossil fuels, technological advancements, and policy incentives have driven a shift towards renewable energy.

Question 3: Describe the geographical factors that influence the location of wind farms in the UK.

Answer: High wind speeds, open flat landscapes or coastal areas, proximity to energy demand centers, and minimal environmental or social conflicts influence wind farm locations.

Question 1: To what extent has the UK's focus on renewable energy contributed to reducing its carbon footprint? Evaluate using relevant examples.

Answer: The UK's investment in wind and solar power has significantly reduced reliance on fossil fuels, cutting greenhouse gas emissions. However, challenges such as intermittency and high costs mean that renewables alone are insufficient to meet all energy demands, requiring a balanced approach with other sources.
