The U.S. Department of Energy has been counting on leftover residue from corn cultivation—such as stalks and cobs—as an abundant future source of renewable clean energy, and touted it as a potential goldmine for farmers as well.

They calculated that harvesting the corn residue may actually result in the release more climate-altering carbon dioxide into the atmosphere than federal environmental regulations allow.…Read More
Forty-four years ago today, Denis Hayes convened the very first Earth Day, an event that drew millions to events across the United States and heralded a new global awareness of the need to preserve our natural resources.

The planning decisions made in those cities will have a lasting impact on the well-being of people within them.…Read More
