Proposition funds flow from out of state

Two energy measures have also attracted large sums:

Proposition 7 would require major increases in renewable energy.

Phoenix billionaire Peter Sperling has poured $3 million into the effort, accounting for nearly all of the money raised by the committee. Sperling's wealth comes from Apollo Group Inc., which owns the for-profit University of Phoenix colleges.

Foes, led by California utilities, have raised $23.7 million. PG&E has donated $12.25 million so far and Edison International $10.25 million.

Proposition 10 would authorize the state to sell $5 billion in bonds to help increase the use of natural gas-burning vehicles.

Backers have raised $3.75 million -- with $3.25 million coming from Clean Energy Fuels, a Seal Beach firm that supplies natural gas. Clean Energy's chairman is Texas oil and gas billionaire T. Boone Pickens.

Aubrey McClendon, chief executive of Chesapeake Energy in Oklahoma, donated $500,000 last month. There is no organized opposition.
