      abstract     = {Wind-solar power has an intrinsic huge volatility and the
                      obvious question arises, is it possible to marginalize it to
                      an extent that the power generation can sufficiently be
                      synchronized with the electric power consumption being
                      volatile as well. We present a novel function describing the
                      volatile system as a whole. The new function, in turn,
                      depends on three characteristic numbers, which means that
                      the volatility of this system is characterized by those
                      numbers. Using the data of the total electric power
                      consumption and the total wind-solar power generation in
                      Germany for the last seven years (2015–2021) taken every
                      15 minutes we determine the characteristic numbers from
                      these data and get the result that marginalizing the
                      volatility is possible with a minimum of required storage
                      capacity, provided (i) a surplus of wind-solar power is
                      supplied about doubling the number of devices, (ii) smart
                      meters are installed, (iii) a different kind of wind
                      turbines and solar panels is partially used. Our results
                      suggest that all the present electric energy required in
                      Germany can be obtained from wind-solar power if (i), (ii)
                      and possibly (iii) are fulfilled. And our results indicate
                      that, because of the minimal necessary storage capacity,
                      controlled wind-solar power can in addition produce the
                      energy for transportation, warm water, space heating and in
                      part for process heating, requiring an increase of the
                      electric energy production in total by a factor of 5. Then,
                      however, a huge number of wind turbines and solar panels is
                      required changing the appearance of German landscapes
                      fundamentally. Our method can be applied to the wind-solar
                      power problem of any country provided a reliable basis of
                      power data exists over a sufficiently long period.},
