The Great Green Hope for lifting America’s economy is not looking so robust.

President Obama, both during his campaign and in his first year in office, has promoted the promise of new jobs in cutting-edge, nonpolluting industries, and such green jobs will be a major issue at his jobs “summit” meeting Thursday.

But, increasingly, skeptics who point to the need for more jobs are wondering why he is not doing more to create green jobs faster.

Growth in clean energy industries and in green jobs has been considerably slower and bumpier than anticipated, industry experts say.

But rather than giving up on its green jobs mantra, the White House will rededicate itself to promoting green industries at the jobs meeting, which will bring together business and labor leaders, politicians and economists.
