I found an article related to Dawn's post about Google's latest solar campus.
This article also mentions one of the factors for sustaining natural capital, as we talked about last week - "Shifting from sale of goods to provision of services". It mentions that although the installations of photovoltaic systems is a common stereotyped as expensive elements, companies like Google, are now beginning to look at it in terms of as beneficial investments through "returns on investment" and "internal rate of return". They mention that it does not need much maintenance (as the the inverters are the only major replacement necessities every 15 years or so), provided that is installed correctly and appropriately integrated into the building.
