Questions & Answers about Ilość energii odnawialnej jest różna w zależności od pogody.
How does the phrase w zależności od affect the word pogoda here?
The compound phrase w zależności od ends with the preposition od (from), which always requires the following noun to be in the Genitive case. Since the base word pogoda (weather) is feminine, it takes the standard Genitive ending -y, becoming pogody.
The English translation uses the verb "varies", but the Polish sentence uses jest różna. Why is that?
In Polish, it is very natural to express the idea of something varying by using the verb być (to be) with the adjective różny (different). You are literally saying the amount "is different" depending on the weather. Notice that the adjective takes the feminine form różna to agree with the feminine noun ilość.
Why is it energii odnawialnej instead of the dictionary form energia odnawialna?
The noun ilość (amount) is followed by the Genitive case to express "amount of". Therefore, both the noun energia and the adjective odnawialna must take their feminine Genitive endings, giving us energii odnawialnej.
Could I use the word liczba instead of ilość for "amount" in this sentence?
No, because ilość is strictly used for uncountable nouns, like energia (energy), water, or sand. You would only use liczba (number) for countable objects, such as a number of solar panels or wind turbines.
