> A number of research teams have tackled the whole “how much could (or should) renewable energy power our grid?” question. Of course, the regions studied, goals of the studies, technology assumptions, and other parameters have varied, so the studies come to various conclusions. Here are some of the most notable studies I’ve seen:

> Finite energy reserves and annual renewable planetary energy reserves (Terawatt‐years). In other words, total known and recoverable reserves are shown for the finite resources (coal, uranium, petroleum, and natural gas), while yearly potential is shown for the renewables.
