Abstract :
Present day electricity is a bargain. It frees mankind from a host of dirty, debilitating occupations—epitomized by the now endangered occupation of legger. Correctly applied, electricity would make a most excellent paramount energy carrier for a post-carbon world. It is, however, only an energy carrier and not a source of energy, the preeminent source for its generation being bargain-priced fossil carbon. But when, in less than a century, that is gone, electricity is a good bet to cost markedly more while being still a bargain. This paper once again shows that mankindʹs energy needs can be met by (i) renewable solar generation of electricity buffered by (ii) massive electricity storage and (iii) a robust distribution grid. The time available for making this switch from fossil carbon to solar is at best a century and possibly as little as fifty years.
