Fuel might be free, but you've got to use it efficiently and effectively.
SHOZ, I know that you don't care what the efficiency is (better than nothing you state), but you've got to do better than digging holes and filling them in to look busy/green.

chart is the return on energy investment of a bunch of technologies...the 3.9 is Solar returning 3.9 times the invested energy over it's entire life...the 1.6 is buffered (with storage to even out it's fluctuations).
I KNOW that we can imagine 90% effcient solar cells with will increase that markedly...but imagining stuff is good doesn't make it so...
