A comprehensive assessment of different energy systems from the economic point of view has to be based on data showing all relevant costs incurred and benefits drawn by the society from the use of such energy systems, i.e. internal costs and benefits visible to the energy consumer as prices paid for power supplied, as well as external costs and benefits. External costs or benefits of energy systems cover among other items employment or wage standard effects, energy-induced environmental impacts, public expenditure for pollution abatement and mitigation of risks and effects of accidents, and the user costs connected with the exploitation of reserves, which are not rated high enough to really reflect and demonstrate the factor of depletion of non-renewable energy sources, as e.g. fossil reserves. Damage to the natural and social environment induced by anthropogenous air pollutants up to about 90% counts among external costs of energy conversion and utilisation. Such damage is considered to be the main factor of external energy costs, while the external benefits of energy systems currently are rated to be relatively unsignificant. This means that an internalisation of external costs would drive up current prices of non-renewable energy sources, which in turn would boost up the economics of renewable energy sources, and the hydrogen produced with their energy. Other advantages attributed to most of the renewable energy sources and to hydrogen energy systems are better environmental compatibility, and no user costs.
