Solar cooling

Cooling from renewable energies, particularly solar cooling (SC) technologies, represents a key issue within the European Union energy policy. The higher temperatures experienced in Southern Europe widely attributed to climate change continue to increase the summer energy demand for air-conditioning. Employing the power of the sun can substantially reduce electricity peaks during the summer months and at the same time reduce CO2 emissions.


Solar heating, a widely accepted concept for hot water production enjoys a high level of market penetration and is widely accepted by the general public. SC, however, although a mature technology, has rather low levels of market penetration and public acceptance. This is due to a number of nontechnological barriers such as its relatively higher initial investment costs compared to traditional air conditioning installations.
