energy. This only changed with industrial revolution when lignite and hard coal

Offering the advantages of easy transportation and processing also as a raw
material, crude oil has become one of the prime energy carriers applied today.
Moreover, natural gas used for space heating and power provision as well as a
transportation fuel has become increasingly important, as it is abundantly
available and only requires low investments in terms of energy conversion
facilities. As fossil energy carriers were increasingly used for energy generation,
at least by the industrialised countries, the application of renewable energies
decreased in absolute and relative terms; besides a few exceptions, renewable
energies are of secondary importance with regard to overall energy generation.
Yet, the utilisation of fossil energy carriers involves a series of undesirable side
effects which are less and less tolerated by industrialised societies increasingly
sensitised to possible environmental and climate effects at the beginning of the
21st century. This is why the search for environmental, climate-friendly and social
acceptable, alternatives suitable to cover the energy demand has become
