We need very large (multi-gigawatt-hour) storage for big cities and megacities, but so far the only viable option to serve them is pumped hydro storage (PHS): it uses cheaper nighttime electricity to pump water from a low-lying reservoir to high-lying storage, and its discharge provides instantly available generation.[76] With renewably generated e

there is no reason to believe that we are in a better position to foresee the extent of coming technical innovations (unless, of course, you are a believer in near-imminent Singularity), the events that will shape the fortunes of nations, and the decisions (or their regrettable absence) that will determine the fate of our civilization during the ne

findings were astonishing. More information was generated in 2001 than in all the previous existence of our species

In large, populous nations, the complete reliance on these renewables would require what we are still missing: either mass-scale, long-term (days to weeks) electricity storage that would back up intermittent electricity generation, or extensive grids of high-voltage lines to transmit electricity across time zones and from sunny and windy regions to
