I wouldn't worry about filtration. It would be more efficient with 2
tanks instead of 3. But the energy expense is minor compared to the
other 2 items. And especially compared to all of your other energy
usage during the day, including your computer. Of course I'm of the
mind set that aquaria are luxury items that are inherently wasteful.
But I'm also a cynic that can't grasp any real significance of me
running plus or minus an extra couple hundred watt devices compared to
the current use and waste of the rest of the world.

Filtration uses less power than heating?

I'm pretty sure the heaters on my 30G tanks have 3amp fuses, whereas my
filters have 5amp fuses... and the heaters only run for some of the day,
whereas the filters are 24/7.

My partner and I have often wondered about the power requirements per tank,
but my way of thinking is that we-get-the-bill-we-pay-the-bill... i'm very
curious to learn exactly how much fish tanks cost to run per week if someone
else can be bothered to do the math.

Tank1 - Non-aggressive community
1x 20W Strip light, 150W heater, 2x poweheads.

Tank2 - Convicts
2x 20W Strips, 150W heater, 1x external cannister filter

Tank3 - Dempseys
1x 25W daylight , 1x 15W nightlight, 150W heater, 1 powerhead, 1 small
external cannister

Tank4 - Livebearers
1x 20W, 100W heater, 1 powerhead

Lights are on 12-18 hours per day, heaters rarely kick in cos the flat we
live in is pretty warm anyway.
