Abstract: Fossil fuels depletion and increasing environmental impacts arising from their use call
for seeking growing supplies from renewable and nuclear primary energy sources. However, it is
necessary to simultaneously attend to both the electrical power needs and the specificities of the
transport and industrial sector requirements. A major question posed by the shift away from
traditional fossil fuels towards renewable energy sources lies in matching the power demand with
the daily and seasonal oscillation and the intermittency of these natural energy fluxes. Huge energy
storage requirements become necessary or otherwise the decline of the power factor of both the
renewable and conventional generation would mean loss of resources.
