LAND NEAR POWER TRANSMITTERS

A friend of mine bought the piece of land above with the intention of turning it into a Herb Garden.  The land is located in a village and everything looks good except for the fact that an electrical transmitter is located very near it. In Feng Shui terms, this means that there is too much yang energy.
For those living near an electrical or power transmitter, it would be best if they move but if that is not possible, then the next best thing is to look for some remedies to neutralise the excess Yang energy.  
One way is by introducing water as this element is one of the best cures for too much yang energy. I heard that my friend has plans to build a small pond in his land and so this will effectively counter the yang energy.  So if he and his family decide to build a house on the land and use it as a holiday home, it would be okay.
