Green sure is a handy word. Over the past few years it has become one of the building industry’smost heavily used catchphrases, salted with marketing potential and earnest ecological concern.

When we use the word green (or associated terms) in a GBA blog, for instance, our intention is to put its use in proper context, whether the post is about an aspect of building performance, the environmental impact of a project, or perhaps a set of green certification criteria.

Our attempted levels of precision and clarity seem to diminish, however, when the word is used to describe an employment category – i.e. green jobs – as was brought to mind this week bya story published in the San Antonio Express. Headlined “Moving to ‘green jobs’ proves tough,” the article points out that employment opportunities have often been scarce for people who have trained for jobs in the alternative-energy sector, despite an analysis by the Texas town’s city government that showed there are anywhere from 2,200 to 60,750 green jobs in the area, depending the criteria used to define “green.” When the term is applied broadly and includes fields that contribute to green practices, for example, the jobs number is big, but shrinks dramatically when it’s applied only to jobs for, say, solar panel installers and wind turbine technicians.

An academic issue

U.S. Commerce Department figures, meanwhile, show 10,000 to 13,000 green jobs, of all categories, in the San Antonio area. In the end, in this economy, trying to accurately gauge a job’s greenness may beside the point. The focus for employers and prospective employees in San Antonio is matching training with demand.

“I really don’t know what a green job is,” Mac Rattan, owner of M&M Weatherization, told theExpress. “I have been doing weatherization for 15 years, so I guess we were green before green became cool.” As a participant in the vastly expanded Weatherization Assistance Program, Rattan’s company increased its workforce fivefold to 100 people, although he is well aware that when the WAP’s stimulus-funded allotments wind down, so will business.

But even amid the economic uncertainty, said Les Shephard, director of the Texas Sustainable Energy Research Institute at University of Texas San Antonio, the best long-term strategy for the community’s academic institutions may be to collaborate on developing renewable-energy technologies and producing graduates who will start businesses and market them. And not worry too terribly much about green labels for their own sake.

“我看整个绿色工作的概念is that it represents a continuum from vocational and on-the-job training to jobs created through research and innovation,” he said.
