Question 1
Directions: Read the following passage and answer the given questions.
Nuclear power and hydropower are crucial components of global low-carbon electricity generation, collectively supplying three-quarters of the world’s low-carbon energy. Over the last 50 years, nuclear power alone has prevented over 60 gigatonnes of CO2 emissions, equating to nearly two years’ worth of global energy-related emissions. Despite this significant contribution, nuclear power is facing a decline in advanced economies, where plants are closing, and new investments are scarce. This comes at a time when the world urgently needs more low-carbon energy sources to meet international climate goals.
The decline of nuclear power could have serious implications for both electricity security and the cost of energy. Projections suggest that nuclear power in advanced economies could drop by as much as two-thirds by 2040 if no significant actions are taken. This would hinder efforts to reduce global CO2 emissions, as outlined in the Paris Agreement and modeled in scenarios like the Sustainable Development Scenario, which calls for rapid cuts in emissions. Achieving these reductions without nuclear power would require massive investments in renewables and energy efficiency, further complicating an already challenging transition to a low-carbon economy. This decline poses serious risks to global climate goals. Nuclear power provides a reliable and consistent source of low-carbon energy that complements intermittent renewable sources like solar and wind. Without it, the costs of transitioning to a fully sustainable energy system will likely increase, and progress in reducing emissions could slow significantly.
To address these concerns, the report suggests several key government actions. These include supporting the safe operation of existing nuclear plants, encouraging the construction of new nuclear facilities, and investing in advanced nuclear technologies. By taking these steps, countries can ensure that nuclear power remains a vital part of the global low-carbon energy mix.
Which of the following statements can be inferred from the passage?
(I) Nuclear power has played a major role in reducing global CO2 emissions over the past decades.
(II) The decline of nuclear power in advanced economies is primarily due to safety concerns.
(III) The cost of transitioning to a fully renewable energy system without nuclear power could rise significantly.
