I guess this is an interesting way to look at it, but I would rather see rankings based on the proportion of companies' power needs that are *met* using sustainable resources. Wal-Mart, for example, should never receive accolades for its pitiful 3% usage, whereas a lot of small and medium companies that are 100% self-sufficient (Procaps Labs, for example) should be highlighted.
I notice that everyone on this list has at least one (in some cases several) reseller of renewable energy certificates (REC) on their list. As a fun exercise, I tallied up an approximate REC value using $0.001/kWh - which is probably a little higher than the average paid here (since such large purchases are probably discounted compared to my point of reference), but is in the right order of magnitude based on the number of similar agreements I have seen as a LEED certification reviewer.
Tally: 10,668,793,171 kWh
Value of potential REC: $10,668,793
Meaning that the average additional cost for these top 10 companies is just over one million dollars per year. This isn't anything to sneeze at, although as we have several of the worlds most valuable companies on this list, I think we should temper our praise except where the percentage (which is a better indication of an organizations commitment to green energy) approaches 100%.
Notably Walmart's 3% and the DOE's 12% (while large in terms of total kWh), does not represent industry leadership in this area.
