Think it might bring down the grid? They're pretty cheap.

There's no easy answer. It depends on the kVA size of transformer feeding your house, your load size relative to that rating and percentage of your load relative to total load at the time.

The billable charge is the bus fare you pay.

If you alone bring extra luggage and use three seats when there are plenty of empty seats, the effect is negligible.

If many people did this and reduced the number of revenue producing seats during busy time, they have to add buses to carry the displaced people, thus each of you is collectively contributing to wasted energy by wasting capacity. Answer? not "eco friendly".

Harmonics are even worse. They're like those people who bring loud arse kids who cause QUALITY of service issues to other customers.

Sheer stupidity like removing existing harmonics filter/PFC and advocating it online is like littering, bragging about it and telling kids littering is good and they should litter more. Advocating something that do not have it to begin with is more like encouraging the purchase of more polluting products.
