Sample IELTS Reading Passage: Medium Text

Renewable energy sources, such as solar and wind power, are becoming increasingly popular due to their sustainability. However, integrating these energy sources with traditional power grids presents several challenges.

First, the intermittent nature of renewable energy is a significant obstacle. Unlike fossil fuels, which can be burned consistently to produce energy, renewable sources depend on weather conditions. For instance, solar panels generate electricity only when the sun is shining, and wind turbines require wind to operate. This inconsistency can lead to unreliable energy supply, making it difficult to balance the grid.

Second, the existing infrastructure is not equipped to handle the variability of renewable energy. Traditional power grids are designed for steady and predictable energy input, typically from coal, natural gas, or nuclear sources. In contrast, renewable energy can cause fluctuations in grid stability as production rates spike and drop. Upgrading infrastructure to smart grids that can respond dynamically to changes in energy input is essential.

Third, there are economic challenges associated with the integration. Significant investments are needed to retrofit existing systems and build new infrastructure to accommodate renewable energy. Additionally, the cost of renewable energy technology, while decreasing, is still relatively high. Governments and private sectors must collaborate on funding and policy-making to make integration feasible.

Finally, regulatory and policy issues also pose challenges. Different regions have varying regulations regarding energy production and distribution. Harmonizing these regulations to foster seamless integration of renewable energy is necessary. Policies promoting renewable energy usage, such as subsidies and tax incentives, can ease the financial burden on developers and consumers alike.

In summary, while the shift towards renewable energy is vital for a sustainable future, overcoming the challenges of variability, infrastructure limitations, economic factors, and regulatory hurdles is crucial for successful integration with traditional energy systems.

Question 7: Renewable energy sources are affected by __ conditions.

Answer Key and Explanations

1. b) Dependence on weather conditions
   Explanation: The passage mentions that solar and wind power depend on weather conditions to generate energy, making this the primary issue.

2. b) It is designed for steady energy input
   Explanation: Traditional grids are built for constant energy generation, unlike the variable input from renewable sources.

3. False
   Explanation: The passage states that significant investments are needed to upgrade the infrastructure.

4. False
   Explanation: Wind turbines require wind to generate electricity, making them unable to operate at any time.

5. a) ii) High costs of technology and infrastructure
   b) i) Need to harmonize energy regulations
   c) iv) Unsuitable for renewable energy input
   d) iii) Variability in energy production

6. steady

7. weather

Common Mistakes and Tips

Common Mistakes:

• Misinterpreting data: Ensure you understand the specific details provided in the passage.
• Vocabulary misunderstandings: Look out for similar words with different meanings in the context.
• Time management: Allocate time to each passage appropriately to avoid rushing through the last one.

Tips:

1. Skim the passage first to get a general idea.
2. Focus on understanding the main idea of each paragraph.
3. Scan for keywords in the questions to locate answers quickly.
4. Practice different question types to become familiar with the format.

Vocabulary

1. Intermittent (adj.) /ˌɪntərˈmɪtənt/: occurring at irregular intervals; not continuous or steady.
   • Example: The intermittent nature of solar power can pose challenges for grid operators.
2. Retrofit (v.) /ˈrɛtrəʊfɪt/: add (a component or accessory) to something that did not have it when manufactured.
   • Example: Many power plants need to be retrofitted to handle renewable energy sources.
3. Fluctuation (n.) /ˌflʌktʃuˈeɪʃən/: an irregular rising and falling in number or amount; a variation.
   • Example: Renewable energy causes fluctuations in the grid’s stability.
4. Subsidy (n.) /ˈsʌbsɪdi/: a sum of money granted by the government to help an industry or business keep the price of a commodity or service low.
   • Example: The government offered subsidies to encourage solar panel installations.

Grammar Focus

Passive Voice: Essential in academic writing to focus on the action rather than the subject.

• Structure: [Object] + to be verb (in the correct tense) + past participle of the main verb.
• Example: Significant investments are needed to retrofit existing systems.

Complex Sentences: Combine multiple ideas and add depth to writing.

• Structure: Main clause + subordinate clause (introduced by conjunctions such as because, although, since, etc.).
• Example: Although the cost of renewable energy technology is decreasing, significant investments are still required.

Conclusion

Successfully integrating renewable energy into traditional systems is a complex but essential step towards a sustainable future. Understanding the academic text related to this topic can help you excel in the IELTS Reading section. Practice regularly, focus on the details, and always manage your time effectively during the exam.
