Let me share with you guys...
My previous setup consumed 757.8 kW (757800W) per month. Largest contributor being my Artica 1/3hp (840W) that ran approximated 10 hours a day (temp range 25ºC to 26.5ºC) amounting to 252 kW/month.
So my aim is to cut that to half... not exceeding 378.9 kW/month.
To put that in perspective, if Singapore is to produce electricity using coal, my old setup would've released approximately 750 kg worth of green house gas into the atmosphere (that's 9 ton a year) Luckily Singapore relies on cleaner ways of producing electricity... but nevertheless the truth is still mind boggling
