The National Security Agency is looking to build a massive $2 billion computer center at the Camp Williams military reservation in Utah, but critics worry it will drain energy needed by current power users, the Salt Lake Tribune’s Matthew D. LaPlante reports. The NSA has already maxed out a power grid in Baltimore, and Utah officials are trying to figure out how they would accommodate such a power-hungry customer. The new facility would itself consume the equivalent of the electricity needed to power all the homes in Salt Lake City.
