SACRAMENTO, Calif. - New tax money from out-of-state businesses may soon be used for school energy upgrades here in California.

State lawmakers proposed a plan to begin using money raised by the recent passage of Prop. 39, which increases taxes on out-of-state businesses.

The proposed bill was introduced at a Sacramento elementary school.  It calls for some of the new tax money, estimated at up to a billion dollars a year, to be spent on heating, ventilation, air conditioning and lighting upgrades in some of the oldest and poorest schools in the state.

Half of the money raised by Prop. 39 is required to go towards renewable energy and clean energy projects.
