I am not demanding you to "self sacrifice" in the sense I don't think you should stay in the dark to use less electricity but more on turn off the lights you don't need.

Similar, don't buy shit you don't need, do a bit of effort to research if maybe you can "sacrifice" a bit of money to buy a greener product or that will be shipped from a closer location etc. The industry is burning fuel to give you the shit you want, for you whims , you can't just blame them.
