Learn Farsi: برای محافظت کردن از اقلیم، باید از توربین‌ها استفاده کنیم. - To protect the climate, we must use turbines.

When the subject of both halves of the sentence is the same (here, 'we'), you can use برای followed directly by the infinitive to mean 'in order to'. You could also use the subjunctive phrase برای اینکه محافظت کنیم, but the infinitive form is concise and very common in formal speech or writing.

Why do both halves of the sentence use the preposition از?

In Farsi, many compound verbs require a specific preposition to connect to their object. Both محافظت کردن (to protect) and استفاده کردن (to use) take از. Even though English uses a direct object for both, Farsi grammar essentially phrases it as protecting 'from' and using 'from' the objects.

Is اقلیم the usual word for climate?

اقلیم is the precise, scientific word for 'climate', especially used in environmental contexts like climate change. You likely already know آب و هوا (literally 'water and air'), but that is much more commonly used to discuss the daily weather rather than long-term climate patterns.

Could we drop the plural suffix ها from توربین‌ها since it refers to turbines in general?

Yes, in Farsi, a generic plural object can often be left in the singular form (just توربین) without changing the overall meaning. However, keeping the ها suffix is perfectly natural here and emphasizes the physical, countable nature of the many machines we need to build and use.
