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 several nontechnological barriers such as its relatively higher initial investment costs compared to traditional air conditioning installations.
