Probably, you have already known, if we want to explain something, we use the conjunctions ПОТОМУ ЧТО, ОТТОГО ЧТО (because). Before we turn to alternative ways of cause description, I would like to explain here the punctuation in the usage of these compound conjunctions, because students ask these questions from time to time. As the previous sentence shows, the most common case is when we write comma before the conjunction. But there are also cases, when comma separates the conjunction. Look at these two examples.
За границей мы чувствуем себя комфортно, потому что знаем иностранные языки - We feel ourselves comfortable abroad, because we know foreign languages. За границей мы чувствуем себя комфортно, возможно, потому, что знаем иностранные языки - We feel ourselves comfortable abroad, probably, because we know foreign languages.
Well, most often, when a sentence includes a parenthetical word (ВОЗМОЖНО - perhaps, МОЖЕТ БЫТЬ - maybe, etc), the conjunction is separated by a comma. A parenthetical word is separated - according to the rules.
At the same time, a compound conjunction can also be separated - it depends on the intonation. Let's say, to write comma in order to show the pause.
Now let's look at the alternative of the conjunction ПОТОМУ ЧТО (because). These are the conjunctions БЛАГОДАРЯ (thanks to) and ИЗ-ЗА (because of), which have the same meaning as ПОТОМУ ЧТО (because), but are used in other situations and grammar structures.
We use БЛАГОДАРЯ [blagadarya] to show a positive cause. Something that is useful.
The structure with a noun:
БЛАГОДАРЯ (thanks to) + noun in Dative case
The structure with a verb or the word "eсть" (remember, we often omit the word "есть", although we imply it):
БЛАГОДАРЯ ТОМУ, ЧТО + phrase describing the positive effect.

Благодаря хорошей погоде мы смогли устроить пикник - Thanks to a nice weather, we could make a picnic.

We use ИЗ-ЗА (due to), when we want to express negative connotation - something that has caused harm or prevented from getting result.
Structure with a noun.
ИЗ-ЗА (due to) + noun in genitive case.
The structure with a verb or the word "eсть"
ИЗ-ЗА ТОГО, ЧТО + phrase describing a negative effect.

Be attentive, the choice of conjunction does not depend on words or phenomena out of context which are considered to be positive or not. All depends on a situation and result.
