The Dirt on Dirty Electricity

Up until recently, the term ‘Dirty Electricity” evoked in me images of the smoke stacks from coal fired power plants, open pit mines and mazes of huge erector-set like structures stringing power lines across the countryside. But the overt pollution of air, water and land resulting from the generation of electricity is only one meaning of the term. The other meaning of ‘Dirty Electricity’, though, specifically refers to one type of electromagnetic frequency called ‘high-frequency voltage transients’. A less visible is a form of pollution that does not appear on the agenda of the environmental movement hardly at all, it may turn out to be just as significant a form of pollution.
