IELTS Vocabulary: Renewable Energy Sources

IELTS Podcast

Renewable energy and sustainable technologies are pivotal in shaping a sustainable future. This article delves into the societal impacts of these technologies, utilizing passive voice to describe processes inherent in their development and deployment.

Grammar Point Covered

The passive voice is often used in English to emphasise the action and the receiver of the action rather than the doer. This is particularly useful in scientific and technical writing to focus on processes and results. For example, ‘The electricity is generated by the wind turbine’ highlights the process and outcome without specifying who operates the turbine.
