I remember hearing about that, but I'm thinking that was a different
affect than just water vapour would produce.

I wouldn't have thought a power plant would introduce enough water to
the atmosphere to make a noticable difference but...

Looking online there are a wide range of estimates for that, some
saying that plants with cooling towers release almost nothing, not
what someone said the other day. Another site said the ones that
use the water and then dump it are usually set up near the ocean
and use salt water with little affect other than right near the
exhaust pipes (warm water).

One site said that a large Nuclear plant attempting to reclaim
all the water it uses would Lose about 30 million litres per day
to evaporation, a tiny perscentage (1% to 2%) of the total water
it uses for cooling. But that number is still quite a bit higher
than I would have guessed.

It also begs the question, is that enough to make a noticable
difference to the weather or climate ?
