The Gobi Desert in the western region is the most suitable for the construction of large-scale photovoltaic power stations; however, due to the sparse population in the western region, the demand for electricity is limited; and due to the long distance, the cost of transmitting electricity to the eastern region is high. In practice, we have to give up the favorable terrain of the western region on the Gobi Desert and turn to the development of the photovoltaic power generation industry in the eastern region where the demand for electricity is greater.
