Massachusetts' fast-growing "clean energy" industry -- companies involved in fields such as solar and wind power, conservation, and high-efficiency energy technology -- is poised to add as many as 3,000 jobs this year, according to a state survey released yesterday.

The green-energy business already accounts for at least 14,400 jobs and is growing three times as fast as other major industries -- like financial services, defense contracting, software and communications, and healthcare technology -- said the Massachusetts Technology Collaborative, which conducted the survey.
