In the past two years, the number of online job postings containing the keyword "sustainability" has more than quadrupled to 8,245 in May, according to Indeed.com, which aggregates online job postings. The number containing "wind" and "solar" more than doubled in the same time period.
Some of that growth might have come from the $800 billion economic stimulus package, about $100 billion of which was devoted to green-related projects, said Robert Pollin, a professor of economics at the University of Massachusetts Amherst.
Much money was devoted to helping companies retrofit buildings to be energy efficient, and according to Mr. Pollin's research, every $1 million devoted to that task created about 17 jobs for the life of the project, he said.
Because many of the jobs are cross-sector, we can't be exactly sure how many were created for what reasons. But it's clear that tens of thousands of Americans are being employed in the clean energy field who might otherwise not have jobs. This rough analysis from the Wall Street Journal illustrates the increase in activity.
