What happens if you live near a power line?
If you’re within 50 of a 765 kv line or transmission tower, you’re more likely to develop cancer and experience increase in triglyceride.

Where does electricity come from in a utility?
Other utilities purchase electricity directly from other utilities, power marketers, and independent power producers or from a wholesale market organized by a regional transmission reliability organization. The retail structure of the electricity industry varies from region to region.
