A trend is beginning to form where professionals are taking their talents and moving them to jobs that can help improve the environment. A growing number of midlife career-changers are trading in their nine-to-fives for jobs more in line with their convictions and concerns for the environment. These "green-collar jobs" are on the rise and the current tally of 8.5 million U.S. jobs in renewable-energy and energy-efficiency industries could grow to as many as 40 million by 2030, according to a report commissioned by the American Solar Energy Society.
And the burgeoning industry is claiming scores of experienced workers who can put to use the skills they've acquired in more established fields such as construction, finance, and marketing. In some cases, the high demand for green career changers translates into a larger paycheck. But more often, the satisfaction of making a positive difference in the world is enough of a boost.
Many people are tired of their jobs and know they want to give back to the environment, but have no idea where to look for a green collar job.
