Renewable energy development and implemented energy efficiency measures are responsible for 70% of the the drop in US carbon dioxide emissions seen since 2007 (when a slow decline began), according to a new report from Greenpeace.

The findings stand in contrast to some of the arguments put out there by detractors of renewable energy — some of who have argued that the drop in carbon emissions was the result of the natural gas tracking boom. The numbers say otherwise, of course.
