The average winter and summer temperatures, which started in 1800, are the longest current series shown in the table. The series on the average year temperature and on hours of sunshine per year started in 1900. For the number of days below of above a certain temperature (ice days, summery days) the ranges started between 1940 and 1950. The complete set of climate data is available from 1980 onwards

Heat is a form of energy. The use of shallow geothermal cold avoids the consumption of electricity for cooling. Figures have been broken down into deep geothermal heat and geothermal energy with or without heat pumps. Geothermal energy is a form of renewable energy. With deep geothermal heat, the pumped up water is sufficiently warm (approximately between 60 and 90 degrees Celsius) for direct consumption via a heat exchanger. The main application is the heating of greenhouses. With geothermal energy, the pumped water is usually not warm enough (about 10 degrees Celsius) for direct consumption. This is why heat pumps are often used to bring the temperature to a sufficiently high level. Geothermal energy can be used both for heating and cooling. The main use of geothermal energy is the heating and cooling of office buildings. Data available from: 1990 Status of the figures: The figures in this table are definite up to and including 2016 and revised for 2017. Changes as of 29 June 2018: Revised figures for 2017 have been added. When will new figures be published? Provisional figures of deep geothermal heat and shallow geothermal energy in the form of heat used through heat pumps for the previous year are published each year in June. Definite figures of all variables for the previous year appear each year in December.
