    I can't understand the logic here - it's certainly cheaper to use vents
    that don't need to use power!

    As far as "better", that depends on too many variables, like prevailing
    winds, average temperature - what I have in mind is, you'll probably need
    more ventilation when the winds are calm and the heat is stifling -
    convective venting might not be enough, so could use a power assist, but
    other than that, I'd invest in one of the passive ones first.

    Cheers!

    They (roof-mounted attic ventilation fans) are also available solar-
    powered, which makes a certain amount of sense: the hotter the sun
    shines, the better it works. Not terribly expensive either
    ($100-200?). I saw some last weekend, but have forgotten the exact
    price.

    Cheers,

    All reports I've seen say that powered vents and turbines do nothing.
    Depending on the area of the country, ridge or gable vents, along
    with soffit vents work better. They don't squeak either.
