That article somehow contends that we will have a stable grid with 2X PV and 7 hours of storage. But it is dark at least half of the time. Keep in mind also the best PV systems in the world make 31% of their nameplate. In NY, USA the average for the year is 15% with days at a time of 0% in the winter.

"Based on the current analysis, the most cost-effective system (for the USA) would cost 11 trillion dollars and require a 5,000 GW PV System and 16,650 GWh of storage."

We can stretch our carbon fuel for as long as we can by using what we have left to build out alternative energy but eventualy it will leave us long before (never) we are ready to leave it.
