What is energy security?

• The ability of a country to store large amounts of energy

• The uninterrupted availability of energy sources at an affordable price

• The use of renewable energy over fossil fuels

• The development of nuclear power plants

How might a country's reliance on imported fossil fuels impact its energy security during a global crisis?

• It exposes the country to supply disruptions and price volatility.

• It reduces vulnerability as fossil fuels are always available globally.

• It increases energy security due to diversified energy sources.

• It encourages immediate transition to renewable energy.

Which of the following scenarios best illustrates the "energy trilemma"?

• A country focuses on nuclear energy to achieve zero emissions.

• A nation struggles to balance energy security, environmental sustainability, and affordability.

Which energy resource is most affected by geopolitical tensions?

• solar

• hydroelectric

• wind

• oil

How does the concept of "energy return on energy investment" (EROEI) influence energy policy decisions?

• Higher EROEI values indicate lower environmental impact.

• Renewable energy always has a higher EROEI than fossil fuels.

• Low EROEI values are preferred for long-term energy security.

• Energy sources with higher EROEI are more economically sustainable.
