Model Essay

Introduction

Renewable energy sources such as solar, wind, and hydroelectric power are increasingly being adopted worldwide as an alternative to fossil fuels. However, a debated issue is whether this shift leads to higher energy prices. This essay will examine both viewpoints and provide an opinion on whether the transition to renewable energy results in more expensive energy.

Body Paragraph 1

One perspective is that the increased utilization of renewable energy spurs higher energy costs. Proponents argue that the initial investment in renewable energy infrastructure is substantially expensive. Solar panels, wind turbines, and other related technologies require significant up-front expenditures for development, installation, and maintenance. Furthermore, renewable energy sources often face volatility; for instance, solar and wind power depend on weather conditions, which can fluctuate and thus impact energy availability. These variables can drive prices higher as the technology and infrastructure stabilize to become more cost-efficient.

Body Paragraph 2

Conversely, advocates for renewable energy assert that it ultimately results in lower energy prices over time. They contend that once the initial costs are amortized, the ongoing expenses are minimal compared to fossil fuels, which have continuous mining, transportation, and environmental costs. Renewable energy sources are abundant and, theoretically, inexhaustible. Solar energy, for example, can be harnessed indefinitely with negligible marginal costs once the infrastructure is established. Furthermore, technological advancements and economies of scale significantly reduce the per-unit cost of renewables, suggesting a potential long-term downward trend in energy prices.

Renewable Energy Sources Cost Comparison

Opinion

In my opinion, while the initial phase of transitioning to renewable energy may be marked by higher costs due to infrastructure investment and technological adjustments, the long-term benefits far outweigh these initial expenditures. As the technology matures and more efficient systems are developed, renewable energy is likely to become not only more cost-effective but also more reliable and environmentally sustainable.

Conclusion

In conclusion, although the initial use of renewable energy can lead to higher energy prices due to infrastructure and technology costs, the overall trend indicates a potential reduction in energy prices over time. The sustainable and inexhaustible nature of renewable energy sources, combined with continual technological advancements, suggests that the long-term impact will be favorable for both the economy and the environment.

• Economies of scale: Cost advantages achieved when production becomes efficient.

Grammar Points:

• Conditional Sentences: Used to discuss potential future trends (e.g., “once the initial costs are amortized”).
• Relative Clauses: Provide additional information (e.g., “which can fluctuate and thus impact energy availability”).

Key Vocabulary Terms

1. Infrastructure (n) /ˈɪnfrəˌstrʌkʧər/: The basic physical systems and structures needed for the operation of a society or enterprise.
2. Amortized (v) /əˈmɔrtaɪzd/: Gradually write off the initial cost of (an asset) over a period.
3. Volatility (n) /ˈvɒlətɪlɪti/: Liability to change rapidly and unpredictably, especially for the worse.
4. Proponents (n) /prəˈpoʊnənts/: People who advocate for a theory, proposal, or course of action.
5. Expenditures (n) /ɪkˈspɛndɪʧərz/: The action of spending funds.

Conclusion

Renewable energy’s influence on energy prices is complex, with both short-term and long-term considerations. As renewable technology evolves, it is crucial to evaluate its economic impacts in conjunction with its environmental benefits. Future IELTS candidates should consider similar topics reflecting global sustainability trends in their preparations. Potential future prompts may include:

1. The role of government subsidies in promoting renewable energy.
2. Comparing the economic impacts of renewable energy versus fossil fuels.
3. The social benefits of transitioning to renewable energy sources.

By mastering such topics, candidates can substantially enhance their writing skills for the IELTS test, moving towards higher band scores.
