"Transmission is the biggest barrier to the development of Wyoming's considerable wind energy resources. But not only do we need to build the lines to carry this renewable energy to market, these lines must be 'right-sized' from the start. The key is to get the maximum number of electrons transferred with the least amount of environmental disturbance."
