Re: [Phys-L] a 50 state plan for renewable energy by 2050

["David Marx" <marx@phy.ilstu.edu>]

There is nothing on the group's site that shows how their numbers are
determined, nor what their plan is for providing energy for transportation. 
It seems to rely 100 % on electricity, except where significant geothermal
resources are available.  What assumptions are made about utility-scale
storage, etc.

It seems like just an effort in public relations.
