On a cold night, what's a good way to reduce heat loss through
the windows? Do the blinds make much difference?

Everything helps, but heavy drapes will do more than the blinds.



In summer it can pay to reflect sunlight hitting east and west
windows. Vinyl blinds let some light through and probably
absorb some. Is there a better way to reduce solar heating
through windows?

In the winter you want to let that sun come in as much as possible. Thee
are coatings that will help in the summer though.
