27 with about 70-percent less carbon emissions than petroleum-based equivalents. They claim it doesn’t impact agricultural crops, land, or water. Green Algae: Biofuels SOUTHERN NEW MEXICO – Columbus will be home to Luna County’s first green energy facility—literally green, in this case. Algae will be cultivated by Sapphire Energy in man-made ponds about 8 miles west of Columbus on the Mexican border, to later be converted to a green goop called algae-based biofuel, oilgae, or algal fuel. “This will be the first Sapphire facility in the country,” says Tim Zenk, spokesperson for Sapphire Energy in San Diego. “We’re looking at different geographies,” says Zenk. “Now our focus is on New Mexico.” Luna County is considered ideal for algae-based biofuel because of the flat desert conditions, the high level of sunlight, and the large amount of underground salt water.
