"This report documents the environmental impact of our facilities and our efforts to reduce their impact. In particular, this report documents: â How we generate and use energy across our worldwide facilities including our corporate offices, data centers, and retail stores by highlighting our fiscal 2012 accomplishments"
Ahem? Ahem yourself. The quote being discussed, and the 75% claim is:
And for all of Apple’s corporate facilities worldwide, we’re at 75 percent, and we expect that number to grow as the amount of renewable energy available to us increases.
Now see page 10 of the report linked above. Notice how retail stores is a separate category than corporate offices.
Bottom line: No, the 75% does not include stores.
