technically there isn't much risk. We carry our phone with us, sleep also put near the bed to charge. That have more EM wave than the substation.

Though, psychologically it may not be so present. It is like opposite neighbour have a few sharp roof thrust pointing towards ur main door like dragon claw. You will feel some threat every time you walk in and out of the house.

you might over come this for nwo... but then later when things dont goes well (life always have up and down, of course,) we will then try to related to the substation bring negative energy and will always have that little torn in our eye and heart. Take note we can;t move the the substations, so you want to move house then?

planting tree will reduce the effect, but if you aware it is there... subconciously you will still free it.

i am not a hard beliver of feng shui... just appreciate ergonomic and pscyological effect - especially in a large investment.
