We, therefore, think that an evolutionary approach has to be designed that starts from facets of the life-world energy concept that are already in accordanc with the science concept. This appears to be possible. Regarding Ogborn's (1986) previously mentioned view that the use of energy in daily life is, as a whole, correct from the scientific point of view if one interprets it as 'available energy' (more precisely as exergy), the everyday use of energy has to be reinterpreted from the point of view of the science energy concept. If, for instance, it is said that energy is consumed in a certain process, this has to be reinterpreted by employing the above energy quadriga: energy is transformed in that process from one form to certain others and may change the place of manifestation (is transported) but the amount of energy does not change (conservation) whereas the value decreases (degradation). In short, we aim at a strategy to nullify the contradictions between the life-world and the science energy concept by interpreting the life-world concept in terms of the energy quadriga.
