Abstract
Abstract A review of the methods of obtaining water in the Canary Islands (Spain) is presented, dividing the islands into two groups: the eastern islands and the western islands. This division is due to the different origins of water resources, with western islands using mainly underground sources, while the eastern ones main source is seawater desalination. Water sources define the way in which water is obtained, as well as the energy expenditure to obtain it. In this review, the energy consumption of different methods of drinking water collection is studied, as well as the resources that make up the energy mix in the Canary Islands. In addition, a projection is made for drinking water consumption and energy consumption related to water use in the archipelago up till the year 2035, in order to observe the expected trends in these sectors.
