In comparison to other means of conferencing, audio conferencing is a little cheaper. This makes less sense close to the equator where the amount of daylight does not vary much in a year, or near the poles where the difference between winter and summer daylight hours is very large. Electrical lighting produces a lot of heat, whereas, if properly controlled, natural lighting generates hardly any heat at all. For some, however, the time change can have more serious consequences to their health. One of the aims of DST is to make sure that people's active hours coincide with daylight hours so that less artificial light is needed.
