The 1960's era house I live in had screened vents that were way too 
small, and in the hottest part of the year the heat in the attic would 
build up past the 150*F range and radiate into the top/ main floor. When 
my landlady's son put in power vents, set to turn on at a certain 
temperature,  the attic temps dropped and the upstairs apartment became 
much cooler compared to previous years. Good quality non-powered 
'whirly-bird' or turbine vents would be nearly as effective and use no 
electricity.
