Hardly a week goes by these days without the announcement of a new job-creating solar plant sprouting up in California.

Today's headlines were about plans for a 500 MW plant in King's County -- one of the areas hardest hit by the recession. Several California-based solar companies are heavily involved with the project, which will create thousands of high-wage jobs during construction.

This solar facility -- which will ultimately provide enough electricity to power 100,000 households -- joins many more that have been put in place, are under construction, or are on the drawing boards in the Golden State. All told, more than 10,000 projects are in the works in the state -- far eclipsing that of any of our state's rivals. (For a complete list, visit www.californiasolarstatistics.ca.gov).

California also is a leader in the manufacture of solar panels. For example, Sunpower, recently announced it will build its first domestic plant to make solar panels in Milpitas, creating more than 100 jobs and joining other solar manufacturers already located in California: Kyocera in San Diego, SolarWorld in Camarillo, Heliodyne in Richmond, SunEarth in Fontana, FAFCO in Chico and Solyndra in Fremont. New start-up companies, like Stion in San Jose, are moving into production mode too. Throughout California, hundreds of solar construction contractors are doing business installing solar equipment.

But there is a cloud on the horizon. Two Texas oil companies, Valero and Tesoro, are mounting a drive to dismantle the catalyst for much of these job-creating solar businesses. Any day now, their ballot measure to effectively kill AB 32 is expected to qualify for the November ballot.

If it passes, it could likely chill billions of dollars of investment in solar facilities in California. That will put thousands of jobs at risk in the Central Valley, Inland Empire, and throughout the state in areas where the sun is being harnessed to provide clean power. It will undermine California's leadership in solar power, and threatens our energy security as well.

The California Solar Energy Industries Association is strongly opposed to the job-killing Dirty Energy Proposition (www.StopDirtyEnergyProp.com). CalSEIA's 220 members are creating local jobs throughout California in clean, renewable energy.

These are in-state construction jobs up and down the career ladder -- from entry level workers to those with advanced technical skills.

California is home to the largest and smallest solar companies because of the State's leadership in recognizing that reliance on fossil fuels is no longer acceptable. Thousands of Californians, from San Diego to Redding are doing business in your community.

In addition, solar energy is helping homeowners and businesses lower their electricity and natural gas bills to zero or near zero, which helps homeowners with their daily budget and makes California businesses more profitable.

That's why we are opposed to the special interest ballot measure being advanced by Texas oil companies. They don't want the competition from the clean energy industry. But we're determined to show Californians that we no longer can afford an addition to oil, as the Gulf oil spill is reminding us daily. We are hopeful voters will agree.
