Politics will continue to define what is "green" or "clean," since these are semantic and political devices, rather than scientific or economic characterizations
A Definition of the “Green or “Clean Economy”—Not What You Would Think
For years, the Obama Administration has claimed that the stimulus will increase employment through "green jobs". But what are green jobs? Are they jobs in the solar and wind industry? Yes, but according to a new study, the majority of green jobs in the United States are actually jobs in waste management (garbage), mass transit, and other non-energy areas, and those jobs are not stimulus-related. Even including those mature jobs, the green or "clean economy" jobs represent just 2 percent of all jobs in the United States, and renewable energy jobs, those touted by the Administration as being "green", make up just 5 percent of the "clean economy" jobs. That compares modestly to the largest sector of the economy--health care--employing 10.2 percent of all jobs, but unlike health care employment, "clean economy" jobs are growing slower than the U.S. economy.
