From Lomberg,
'...a modern windmill($3-million installed cost)can produce the energy used for it's own production within just three months.' circa 1997 (page 135)
The present TESLA (PANASONIC) automotive batteries are reflecting a 20-year service life.
For their 'installed cost',it would be great to see a life-cycle cost analysis.The US Commerce Dept. tracks this sort of thing,although it may be proprietary.
