What is a significant benefit of the energy island concept mentioned in the text?

• It can power different countries around the North Sea at the same time

• It can be used for agricultural purposes

• It will serve as a tourist attraction

• It will reduce the number of ships in the North Sea

Answer explanation

The energy island concept allows for the simultaneous powering of multiple countries around the North Sea, enhancing energy collaboration and efficiency, which is a significant benefit compared to the other options.

Based on the information provided, what is a likely long-term impact of building interconnected energy islands in the North Sea?

• Increased energy security and collaboration among European countries

• Decreased employment opportunities in the region

• Reduced need for renewable energy sources

• Increased isolation of European countries

Answer explanation

Building interconnected energy islands in the North Sea is likely to enhance energy security and foster collaboration among European countries, as it allows for shared resources and improved energy distribution.

What is the approximate capacity of sixty gigawatts in terms of nuclear power plants?

• Forty nuclear power plants

• Ten nuclear power plants

• One hundred nuclear power plants

• Twenty nuclear power plants

Answer explanation

Sixty gigawatts is roughly equivalent to the output of forty nuclear power plants, as each plant typically generates about 1.5 gigawatts. Therefore, the correct answer is forty nuclear power plants.

How long is the Viking Link subsea power cable?

• 765 kilometers

• 500 kilometers

• 1000 kilometers

• 250 kilometers

Answer explanation

The Viking Link subsea power cable is 765 kilometers long, making it one of the longest interconnectors in the world. This length allows it to efficiently transmit electricity between the UK and Denmark.

Why will large storage facilities be required in the future energy system?

• To meet the ever-growing need for energy and support transmission infrastructure

• To replace all existing power plants

• To reduce the use of renewable energy

• To increase the cost of electricity

Answer explanation

Large storage facilities are essential to accommodate the increasing energy demand and to ensure reliable transmission of energy, especially as we integrate more renewable sources into the energy system.

Suppose you are tasked with planning the integration of 50 gigawatts of offshore wind into the electricity grid. What factors would you need to consider to ensure efficient and timely deployment?

• Anticipating planning and investments, upgrading transmission infrastructure, and ensuring storage capacity

• Only increasing the number of power plants

• Reducing the use of renewable energy sources

• Ignoring the need for new technology

Answer explanation

To integrate 50 gigawatts of offshore wind, it's crucial to anticipate planning and investments, upgrade transmission infrastructure, and ensure storage capacity. These factors enable efficient and timely deployment, unlike the other options.

How can hydrogen help secure electricity supply for industrial sites in the future?

• By storing hydrogen and using it during peak hours

• By increasing fossil fuel consumption

• By reducing the need for electricity

• By eliminating the need for renewable energy

Answer explanation

Storing hydrogen allows industrial sites to use it during peak electricity demand, providing a reliable energy source and helping to balance supply and demand without increasing fossil fuel use.

What is one of the three levers for the energy transition mentioned in the text?

• The energy efficiency part, which is reducing energy consumption

• Increasing fossil fuel usage

• Building more coal power plants

• Reducing the use of renewable energy

Answer explanation

The correct choice highlights energy efficiency, which focuses on reducing energy consumption. This is a key lever for the energy transition, unlike the other options that promote fossil fuels or coal, which are counterproductive.

Hydrogen is described as being available in what kind of quantities?

• Virtually unlimited quantities

• Very limited quantities

• Only in small amounts

• Only in certain countries

Answer explanation

Hydrogen is abundant in the universe, primarily found in stars and gas giants, making it available in virtually unlimited quantities. This distinguishes it from other resources that may be limited or region-specific.
