Abstract: The developed countries in European economy countries have focused on promoting energy consumption and carbon dioxide emissions reduction since 2018. The technical model analysis of solar thermal utilization in Europe is intended to provide reference for rural solar cascade thermal utilization in China. By analyzing the low-carbon energy supply pattern in these countries, it is found that the residential structure represented by small villages in Europe is different from large urban agglomerations in China. In the energy field, it is highlighted by the rapid development of decentralized low-carbon buildings combined with heating and heating in winter. In addition, through the analysis of solar thermal application in Europe, it is believed that the key prerequisite for promotion of solar thermal utilization is to reduce the cost of solar heating elements and improve the efficiency to increase secondary profits. Solar thermal utilization is the most economical and reliable way in the long run.

Key words: Solar energy, Heat utilization, Renewable energy, Low carbon technology
