gamer that is irrelevant really ...it should be about doing the best you can...and don't underestimate the impact of frequent washing
First there is the electricity use
Second the water use - I think lots of people don't understand that in order to get that water into your taps, clean enough for you to drink, takes a lot of resources - energy, chemicals. And then the water that goes down the drain into the sewage obviously then needs processing too.
Washing products - even environmentally friendly stuff has to be manufactured, packaged, transported.
Wear & tear on machine - washing machines are designed/manufactured to last a certain no of washes. Your machine will break down/need replacing sooner. And energy & resources needed to make the machines, transport them and dispose of them.
Same on your clothes (bedding/towels) - more frequent washing causes more wear and hence they will need replacing more frequently. With all the associated production, manufacturing, transport costs.
And obviously if they are tumble dried you have the electricity used, manufacturer of drier, disposal of drier...
