Hi SRSrocco, thanks for your coments.

Comparing highways with renewable energy is not the smartest thing to do. Renewables can and will help just because they are renewable.

As for highways you're prabably right, my post shows how hard the gap will be to fill. Even with a steady increase in production from other energy sources the comsumption rates of today aren't likelly to prevail for long.

I'm not saying that you're wrong, the math is on your side, I just hope for a better future.

Lads...let me clear this up...if you will...all these so called renewable technologies will need plenty of R-A-W  M-A-T-E-R-I-A-L.  And of course lots of energy to mine..ship..manufacture and produce.  Of course there will limited and local use of these technologies for sure.  But for wide spread use to PLUG and PLAY our current lifestyle....you got better odds playing the LOTTO.

Renewables and reparing and replacing current infrasture will be in competition for ever depleting resources at ever increasing costs.  I am an optomist...but being pragmatic today might save more skins.
