Transmission Lines: The High-Voltage Backbone of Modern Energy

Transmission lines, with a vibe score of 8, are the high-voltage highways that transport electricity from power plants to substations, and ultimately to consumers. The first transmission line, built in 1882 by Marcel Deprez, was just 15 km long and operated at 2 kV. Today, transmission lines span millions of kilometers worldwide, with some operating at voltages as high as 1,100 kV. The development of high-voltage direct current (HVDC) transmission lines has further increased efficiency and reduced energy losses. However, the construction of new transmission lines is often met with controversy, particularly regarding their environmental impact and the use of eminent domain to acquire land. As the world transitions to renewable energy sources, the importance of transmission lines will only continue to grow, with an estimated $1.5 trillion investment needed by 2050 to upgrade and expand the global grid.
