There is a big difference.
The Earth's electrical field subtle ground energy) is mainly a continuous direct current (DC) producing field that has influenced life on the planet throughout time. Home wiring systems use alternating current (AC) and unless at a very low frequency and/or low power, AC is foreign to our biology. AC, and other forms of man-made electromagnetic fields (EMFs), are being researched as possible factors in a variety of stress-related responses. Many people are sensitive to EMFs and studies show an “association,” but not cause and effect, with some health issues.
