The Green Capital Alliance study finds a three-fold expansion in the number of Sacramento area clean technology companies over the last five years.
"We're leading the state of California with green job growth of over 87%."
Bill Mueller heads the non-profit Valley Vision which manages the Green Capital Alliance, a group promoting green jobs.
He says about 13,000 Sacramento area people work in clean-tech now. That's about 200 more than the number of people who work in farm-related jobs.
Mueller says the region is attractive to the green tech industry for a number of reasons.
"We have the proximity to the state capitol, we have amazing educational institutions, and then you have companies headquartered here that have great promise."
…companies such as Pacific Ethanol and OptiSolar.
Mueller says the growth in green-tech has been spurred by federal grants, which have totaled $300 million in recent years.
