Here’s a thought on electricity consumption

It got me thinking just the other day about electricity consumption with a planted aquarium. Now we use a lot of lights with our plants as you might expect. We also use LED lights because of their lower electric consumption but have some T5s which use a fair bit more as you might guess. Quite how much I don’t know but it got me thinking about consumption and when hobbyists have their lights on and for how long.

Our electric meter has day and night time setting and night time is almost half the price of the day time. I then quite literally had a light bulb moment…

wouldn’t it be better to use electricity at night when the price is cheaper than during the day?

Although not always practical, we have started running some of our lights at night (between 11pm – 7am), thereby cutting our costs.

Do you think this is a good idea for you at home and your planted tank?

Lets say you arrive home at 6pm, so you could have lights come on then, and go off at 2am in the morning, this way you too could be using cheaper electric (assuming you have the same set up as us), and run your lighting for the normal 8 hours a day.

What do you think? I would live to hear your thoughts.

  1. I don’t have an electricity meter like this- sounds great though! I only have an itty-bitty 28l aquarium with a bunch of shrimp in it but I have wondered what their carbon footprint is in comparison to the size of them! Shipping of shrimp, making of the aquarium and all the bits and bobs inside and then the constant heat/light/filter/bubble maker combo to keep them happy make me wonder if this hobby could ever be very eco friendly ;).

  2. When you put it like that, shrimp are probably one of the least carbon footprint friendly inverts around :) I think with more time, electrical products will become cheaper to run (a while off yet in general).

    But do you think you might change your lighting times with the view to saving a bit of cash on your electricity?

  3. That sound like Economy 7, and for the average household it’s actually more expensive as the cost of daytime electricity is higher in some cases 3 or 4 times as much as the night tariff.
    I have just dropped Economy 7 for a flat rate, OK at night the price is about double, but the daytime price is half what it was. So as most households use the bulk of their electric between 7.00am and midnight it would probably be of no benefit, unless you have Electrovoltaic :)

    1. WOW. That’s a huge drop in electricity use. Well done.

      Interesting to hear about the peak usage in Oz though.

      So how are your plants doing now Nathan with the LEDs compared to the halides?

  4. Seems like a great idea, with work I only usually get 1 hour viewing time. If I started turning them on at 6 I’d get about 5 hours to admire my tank.
