20 biggest on-site 'green power' generators

Intel is still king of the hill when it comes to the EPA's quarterly Green Power list, but Kimberly-Clark wears the crown for investing in the most on-site renewable energy technology.

Technology giant Intel still leads the nation in its purchases of green power, using more than 2.5 billion kilowatt-hours of energy generated by renewable sources, predominantly solar and wind.

That is according to the latest edition of the Green Power Purchasing list, which is published quarterly by the U.S. Environmental Protection Agency. The company's percentage of green power as a total of all electricity consumed remained about the same from the second quarter to the third quarter, if you glance at the most recent past list.

The ranking is based on data reported to the EPA's Green Power Partnership program. It reflects electricity generated by renewable sources, and it only focuses on U.S.-based operations. Companies or organizations get credit for buying renewable energy certificates, for investing in on-site generation, or for using utility green power services.

Here are all the latest list leaders:

Personally, I spent the most time looking at the on-site generation list, because that reflects the organizations that are actually taking a chance on green energy technologies. Here's that Top 20 list in its entirety:

  1. Kimberly-Clark (8 percent, or 193.3 million kilowatt-hours) - Biomass
  2. U.S. Air Force (1 percent, or 62 million kilowatt-hours) - Biogas, solar and wind
  3. BMW Manufacturing (37 percent, or 61.8 million kilowatt-hours) - Biogas
  4. Wal-Mart Stores (1 percent, or 37 million kilowatt-hours) - Biogas, solar
  5. City of San Jose, Calif. (16 percent, or 31.8 million kilowatt-hours) - Biogas
  6. City of San Francisco (4 percent, or 31.6 million kilowatt-hours) - Biogas, solar
  7. Nassau County, New York (15 percent, or 29.1 million kilowatt-hours) - Biogas
  8. SC Johnson & Son (14 percent, or 26.8 million kilowatt-hours) - Biogas
  9. City of San Diego (8 percent, or 20.3 million kilowatt-hours) - Biogas, small-hydro and solar
  10. Kohl's Department Stores (1 percent, or 20.1 million kilowatt-hours) - Solar
