Whoa, just as I start this reply there's Uma Thurman topless with DeNiro on the TV - hold on here - what the heck am I watching? Mad Dog & Glory?! Well now, that's a way to start a Saturday morning!

I disagree with parts of the 'Reality" pdf simply because the author speaks more of a total 'energy crisis' than just using less barrels of 'light sweet crude' & appears much more concerned with pollution than an alternative to the internal combustion engine. While I will agree that there isn't a free lunch the whole pollution debate belongs on a whole 'nother thread.
I'm sure we could have some 'lively' discussions about that!
I still think that electric is the way to go. It has more future than any other other foreseeable alternative (misty eyed - love that one Franc!).
Hydroelectric expensive? Sure, if you build new dams & mess with the rivers behind them. But we have hundreds of dams that could easily be converted back into using a turbine. Solve all of our electric needs? Of course not, but every little bit helps.
