I find the electric transmission grid quite interesting. The U.S. electric transmission grid consists of an additional than 200K miles of high-voltage transmission lines (230 Kilovolts and bigger). Transmission lines carry electricity from power plants to areas where electricity is necessary and needed. Electricity travels at nearly the speed of light, arriving at its source at the speed of light. Shareholder-owned electrical firms invested about $49 billion in the nation's transmission method from 2000 to 2007, and are expected to pay even more in the future. Certain trade magazine report this information. T&D World magazine, as an example, is for designed for engineers and operations professionals in the electrical power transmission and distribution industry.
