Wind, wave and tides all suffer from the fact that they are variable sources of power output. For example, there will be times when due to windless days or calm seas—and both can occur for periods of several days even in the winter time—they are producing little or no power.
Insofar as this shortfall has to be made up by electricity from conventional power stations, these newer energy sources would not necessarily reduce the installed capacity of such conventional stations needed to meet the total demand on windless or calm days. What the newer sources will do is to save fuel that would otherwise be burned in conventional power stations.
Pumped storage reservoirs could in principle be used to counter this effect, but there 1 is not enough additional reservoir capacity available. We therefore face the same type of storage problem as in solar energy. Thus, unless some new method of energy storage can be developed or we move to the widespread use of a fue
