Josh del Sol got curious in the summer of 2011 after a friend linked a serious illness to the recent installation of a smart meter." Del Sol subsequently learned that electrical utilities across North America had been quietly installing "smart grids" that ... monitor Internet-connected meters and appliances in homes and businesses. Now, del Sol is on the verge of premiering a feature-length documentary ... titled Take Back Your Power, disclosing questionable industry practices in support of implementing networked control systems for power plants. The film links billing mistakes, invasive monitoring, even human illnesses to the rising use of smart grids in the U.S. and Europe. "Take Back Your Power delivers an ominous, powerful message about the energy industry's shift to closely watching how customers use energy in their home in an invasive, controversial manner," says Lee Waterworth, president of Yekra, a video-on-demand company. Del Sol says access to industry sources was tough. "We had a difficult time getting anyone in the industry to talk to us on camera once they found out that we were wanting to get to the bottom of some of these concerns," he says. The filmmaker was surprised by the contrast between the views of industry officials and those of ordinary citizens trying to get to the bottom of safety, privacy and health concerns. Del Sol hopes the documentary helps to prompt the electricity industry "to provide more transparency, accountability and clarity on the issues we explore in the film."
