· 170 million new solar thermal systems using standard technologies and 120 million new solar thermal systems using emerging technologies will need to be installed by 2030 to achieve the target of 400 million dwellings with solar thermal technologies for water heating.

· Italy, Brazil and the United States posted year-on-year growth rates of 83%, 28% and 19%, respectively in the deployment of standard solar thermal technologies in 2021.

· Smart heat-storage systems, heat pumps and direct solar heating systems and centralised solar power combined air conditioning systems are emerging solar thermal technologies that work intelligently to optimise self-consumption.
