The U.S. Department of Labor's Bureau of Labor Statistics doesn't have current projections about how many jobs these industries could provide. But a BLS economist said given the swelling interest in climate issues, there will probably be new information soon.
Meanwhile, some well-known individuals have been touting the green arena.
In a May 2006 BusinessWeek article, Bill Joy, co-founder of Sun Microsystems and a partner at Kleiner Perkins Caufield & Byers, a Menlo Park, Calif.-based venture capital firm, said: " ... I think the greatest legal creation of wealth today is in the green area - not just in the U.S. but in the developed world. ... There will be an enormous amount of new green technology, new wealth, and we are trying to create the Googles, the Microsofts of the new era."
Greenhouse Gases Begone - Green Job Growth Begin
Vital to fighting global warming, experts say, is the reduction of emissions of greenhouse gases, predominantly carbon dioxide.
The main cause of global warming is human activity, particularly carbon emissions from residential and commercial buildings, power plants and transportation, according to scientists.
Eileen Claussen, president of the Pew Center on Global Climate Change, said green jobs will burgeon in various new technologies needed to fight global warming.
"If we really are serious about addressing global warming, we will need new technology in transportation, energy technology-renewable [energy], technology related to carbon capture and sequestration, new building-related technology [to cut emissions from buildings], air conditioning, insulation, windows, light [fixtures]," Claussen said. "But I think you have to balance that with jobs in old technology that will go away. The world is going to change, and every time you have a change there are winners and losers."
Still, she said she believes there will be an overall growth in green jobs.
Claussen said addressing global warming will drive a need for non-technology-related jobs, as well: state and national government officials to write rules about how new technologies are used; economists to evaluate costs and benefits of investments; and international negotiators to hammer out global frameworks as technology expands.
"No sector of the economy will be untouched," Claussen said.
Renew that Fuel
Renewable energy, derived from various sources such as biofuels, wind and solar, also will be a wellspring of green jobs, experts say.
According to the Renewable Fuels Association, an industry trade association, the ethanol industry in 2005 supported the creation of more than 153,725 jobs in all parts of the U.S. economy, bolstering household income by $5.7 billion. There are currently 115 biorefineries in the United States, RFA numbers show, while 79 refineries are under construction and seven are being expanded.
Michael Jones, president of the bioenergy division at The Richmond Group USA in Richmond, Va., said bioenergy is a thriving part of the U.S. economy, and projects continued growth-including more green jobs-for the next several years.
Jones deals with recruiting and staffing for the bioenergy industry, focusing on professions such as construction engineers, plant managers, process engineers and chemical engineers.

"You can expect at any size facility [biorefinery] to generate anywhere from 20-100 jobs, depending on the size of the facility. That's just in operations for the plant, that doesn't count outside vendors, construction," Jones said. "On one level manufacturing in the U.S. has gotten a really bad rap-it's tough to find people who are making things, and I think we are at a turning point where energy is going to be one of those things people are excited to manufacture."
