Learn Portuguese (Portugal): Não temos nenhuma dependência do combustível da cidade. - We have no dependence on the fuel from the city.

In Portuguese, double negatives are standard. While Não temos dependência is understood, adding nenhuma sounds much more natural, similar to saying 'We do not have any dependence.' Notice that nenhuma is feminine singular to match the noun dependência.

Why is it dependência do combustível when in English we say 'dependence ON the fuel'?

In Portuguese, the concept of depending takes the preposition de, not em (which usually translates to 'in' or 'on'). Here, de combines with the masculine article o (for o combustível) to form do.

Could we say combustível na cidade instead of combustível da cidade?

They mean slightly different things. Using da (de + a) means the fuel belongs to or is provided by the city ('the city's fuel'). If you said na cidade (em + a), it would just mean any fuel that happens to be physically located in the city.
