Well it obviously depends what you use but for example I basically run four Tunze 6105s. If I just ran these full power all the time it would be 35W x 4 x 24 = 3.36 kWh per day. If I alternated flow it would cut it down by half and then if I also just reduced flow to 20% or so at night the savings would be even better at approximately 35W x 0.5 x 4 x 12 + 35W x 0.2 x 4 x 12 = 1.176 kWh per day. Savings of 2.184 kWh per day. This will add up to power savings and while yes not substantial if combined with a few other "miniscule" ideas it could add all add up to something substantial.
