PEP CASA Grande Plant Reaches 'Near Net Zero'.......
........................for Sustainability

Frito-Lay's Casa Grande, Ariz., plant is nearly self-sustaining in water, heat and electricity.

Too long to paste, 2 page story, but the headlines say it all, great strides in alternative energy in industry are happening. I posted on MKC linked to this. Like upgrades on conputers, the alternative energy industry will be sustainable itself as more and more go to it, and users will need replacements and upgradres in time.
