Study Says Algae Biofuel Has Dirty Life Cycle

Algae has seemed like a great biofuel candidate because it’s extremely efficent at creating energy from sunlight and it could potentially form closed loops for power plants – absorbing exhaust while creating new fuel – but a recent study has knocked algae off its pedestal. University of Virginia researchers have found that the life cycle of algal biofuel produces high levels of greenhouse gas emissions — much more than it sequesters. The culprit is the large amount of fertilizer used to produce the algae.  The fertilizers come from petroleum-bases sources and emit nitrous oxide.  The researchers propose using fertilizer from sewage plants as a way around the problem.
