Walmart: huge jump in green power use rankings

According to the United States’ Environmental Protection Agency Green Power Partnership, 28% of the total power used by Walmart Stores in the US comes from green (renewable, including solar, wind, geothermal, biogas, biomass, and low-impact hydroelectric sources) power sources. Ranked by total green power use, this has moved Walmart from twelfth place in the 2011 rankings (for 2010 usage), with 263,533,433kWh of green power usage, to 3rd place in the recently released rankings, with 872,382,088kWh of green power usage in 2011.

In the 2012 rankings (2011 usage) the top ten companies in the National Top 50 in green power usage are Intel Corporation, Kohl’s Department Stores, Wal-Mart Stores, Inc. / California and Texas Facilities, Whole Foods Market, Johnson & Johnson, City of Houston, TX, Starbucks, City of Austin, TX, Staples, and Hilton Worldwide. US EPA publishes this data to encourage procurement of electricity from green sources.

GallonDaily suggests to US EPA that ranking by total green energy use is a poor indicator as it does not encourage energy conservation. Our suggestion is that the rankings should be presented only by percentage of electricity used that is obtained from renewable sources, thereby giving small and medium sized electricity users the chance to win some recognition and not serving as an inhibitor of energy conservation. Expect us to provide some more analysis in this direction in the next issue of Gallon Environment Letter.
