The EPA ranked the paper company number one because of the nearly 193 million kilowatt hours (kWh) of energy used to run Kimberly-Clark''s facility in Everett, Washington, that is generated on-site from waste produced in making paper pulp, the story stated.
According to the story, the power generated by Kimberly-Clark represents more than 7 percent of the electricity the company would otherwise have to purchase.
Collectively, the top 20 companies produced and used more than 736 million kWh of on-site green power, which the EPA said was equivalent to the amount of electricity needed to power more than 61,000 U.S. homes, the story noted.
