class=\"has-small-font-size\">A typical solar thermal system used in Greece has a collector area of 2,5m<sup>2<\/sup> and a water store around 150 l. The system usually replaces an electric storage water heater. The average collector output is 683 kWh\/m<sup>2<\/sup>\/y . The avoided CO<sub>2<\/sub> emissions correspond to 989 g CO<sub>2<\/sub>\/kWh. As such, a typical thermosiphon in Greece saves 1688 kg. CO2\/y.<\/p>\n\n\n\n<p class=\"has-small-font-size\">The average distance covered by a family car is 12 000 km\/year and the average emissions of a new Internal Combustion Engine (ICE) car is about 120gr\/km. An electric car, in an optimal scenario where it would be fully supplied with electricity from renewable sources, could save all emissions of an ICE, equivalent to about 1400 kg. CO2\/y. It should be noted that, in most cases, the CO<sub>2<\/sub> content of the electricity from the power grid used by the electric car should be deducted from the referred savings by an electric car.<\/p>\n\n\n\n<div style=\"height:26px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<h4>Energy cost \u2013 ranges for different solar thermal applications<\/h4>\n\n\n\n<p class=\"has-small-font-size\">The graph indicates the range of solar thermal heat costs for different types of solar thermal systems in different European regions, based on the Levelised Cost of Heat (<a href=\"file:\/\/\/C:\/Users\/PedroDias\/Dropbox%2520(SOLARHEATEUROPE)\/Pedro%2520Dias\/Documents\/0-TEMP\/FROnT_D3.1_elaboration-of-a-cost-estimation-methodology_final2016_.pdf\">LCOH<\/a>). In simple terms, the LCOE indicates the average costs per energy unit average costs of per energy unit supplied over the lifetime of the system. This is compared with the range of costs for useful heat from reference sources, which considers the losses by converting natural gas and electricity into heat. A conversion efficiency of 85% for gas and 95% for electricity is assumed. The costs of natural gas and electricity are based on values for domestic consumers in the second half of 2019.<\/p>\n\n\n\n<p class=\"has-small-font-size\"><strong>Sources:<\/strong> Solar Heat Europe, <a href=\"http:\/\/solarheateurope.eu\/project\/solar-thermal-markets-europe-trends-market-statistics-2016-published-november-2017\/\">Solar Thermal Markets In Europe<\/a> \u2013 Trends And Market Statistics.
