Using Carbon to Fight Carbon

Using Carbon to Fight Carbon Renewable Energy World: "California, United States -- Carbon dioxide seems to be the evil nemesis in a world preoccupied with its contributions to climate change. The less CO2 you emit, it seems, the better citizen you are, and with good reason. But at algae-to-biofuel facilities across the nation, carbon dioxide is not only not the enemy, it's an essential partner to helping achieve a low-carbon future.
CO2 — along with sunlight and water — is needed to grow algae, which can in turn produce oil, otherwise known as “oilgae” or “green crude.” While in its nascent stages, the “oilgae” industry is making strides toward commercial production, all while putting CO2 – designated a pollutant by the Environmental Protection Agency last year – to work as a needed, and yes, valuable, feedstock."
