Limited water availability can also affect the expansion of solar power. Solar PV has very low water needs, mainly for cleaning solar panels. In contrast, concentrated solar power (CSP), which is more suitable for delivering baseload electricity, requires substantial freshwater for its steam turbines (INEA, 2018). Reduced availability of freshwater could therefore result in power losses. There are several adaptation options that reduce water consumption. They include alternative cooling technologies such as dry-cooling and repurposing of excess water from thermal power generation to clean mirror components (Frisvold and Marquez, 2014).

    Why? Does not CSP require direct insolation whereas PV yields certain electricty also with a cloudy sky?
