The times when climate and environmental protection were always clearly on the «good» side are over. In the real-life implementation, alternative energies collide with nature conservation and species protection, as, e.g. in the case of off-shore wind farms. The discussion about «clean» nuclear energy is also difficult. In general, this means that one must take a closer look, weigh up the (long-term) impacts and evaluate the planned measures accordingly in a comprehensive manner.
There are also side aspects to consider regarding air quality measurement. It is almost a paradox when air quality is measured by driving vehicles through the city. If the car has an electric drive, this has, at best, a NO2-reducing effect. The fine dust pollution from brake and tyre abrasion remains. And the environmental problems associated with the production of the necessary car batteries are widely known.
A very topical issue at the moment is energy supply and energy consumption. There are also substantial differences in energy consumption of air quality measurements. The containers that operate the public measurements have an annual energy demand of 3,500 kWh to more than 11,000 kWh, depending on the equipment. This means that even the more economical measuring stations consume more than a typical 2-person household.
With the Hawa Dawa measuring devices, the energy-consuming conditioning of the air before measuring is taken over by a calibration algorithm through the innovative use of artificial intelligence. This means that the annual energy consumption of our measuring devices is at the level of a standard household freezer – i.e. a fraction of the energy that has to be provided for a measuring station.
