Hello. I have seen the following sentence.
However, people have to build dams to use this energy. and as dams cost a lot money, so water energy is expensive.
I have never found "as" used like in the above sentence. Is it used to have the meaning of "such", please?

    It looks as though the sentence has been constructed from these two sentences in Interchange Workbook 2

    However, people have to build dams to use this energy. Dams cost a lot of money, so water energy is expensive.
    Interchange Workbook 2

    If you really need to make one sentence out of those two, I think it's preferable to use either "since" or "so":

    1 However, people have to build dams to use this energy and, since dams cost a lot of money, water energy is expensive.
    2 However, people have to build dams to use this energy, and dams cost a lot of money - so water energy is expensive.

    Edit: We more usually find the as...so construction in comparisons, where "as" means" "just as" (in the same way).
    (Just) as the cow gives us milk, so the hive gives us honey.
