LOS ANGELES (AFP) – California’s environmental regulators approved an ambitious plan aimed at slashing greenhouse gas emissions in the state by 30 percent over the next 12 years, officials said.

The California Air Resources Board (CARB) has backed a series of measures in a plan which sets out a timetable for achieving emissions standards outlined in a 2006 bill signed by Governor Arnold Schwarzenegger.

“This plan is California’s prospectus for a more secure and sustainable economy,” said CARB Chairman Mary Nichols.

“It will guide capital investments into energy efficiency to save us money, into renewable energy to break our dependence on oil, and promote a new generation of green jobs for hundreds of thousands of Californians.”

Key provisions of the plan are a cap-and-trade system covering 85 percent of the state emissions.

Additional recommendations of the plan include implementing California‘s clean cars standards and increases in the amount of clean and renewable energy used to power the state.

The scoping plan also calls for simple measures such as campaigns to encourage consumers to reduce their carbon footprint through carpooling and adjusting thermostats to use less energy.

Mark Z. Jacobson and other Researchers at Stanford University have completed the first quantitative, scientific comparison of alternative energy solutions by assessing not only their potential for delivering energy for electricity and vehicles, but also their impacts on global warming, human health, energy security, water supply, space requirements, wildlife, water pollution, reliability, and sustainability.

Based on their findings their list for the best sources of alternate energy looks something like this for Energy Production:

  1. Wind power
  2. concentrated solar power (CSP)
  3. geothermal power
  4. tidal power
  5. solar photovoltaics (PV)
  6. wave power
  7. hydroelectric power
  8. a tie between nuclear power and coal with carbon capture and sequestration (CCS).

While their Vehicle Options List looks something like this:

  1. Wind-BEVs (battery electric vehicles)
  2. wind-HFCVs (hydrogen fuel cell vehicles)
  3. CSP-BEVs
  4. geothermal-BEVs
  5. tidal-BEVs
  6. solar PV-BEVs
  7. Wave-BEVs
  8. hydroelectric-BEVs
  9. a tie between nuclear-BEVs and coal-CCS-BEVs
  10. corn-E85
  11. cellulosic-E85.

According to researches “the options that are getting the most attention are between 25 to 1,000 times more polluting than the best available options.”
