There are many problems with these power meters including increased power bills (they were touted as vehicles to save power and money), violations of privacy (the power companies are gathering data of power usage and selling this information to third parties), and possibility of cyber-hacking of the power grid with the ability to turn off our power.

The electromagnetic frequencies from the meters are in the range that may cause cancer, and health effects of smart meters include but are not limited to depression, anxiety, insomnia, palpitations, and decreased fertility in men.
