LOS ANGELES -- The Los Angeles City Council has moved toward banning plastic bags at grocery stores in the nation's second-largest city.

The council voted 13-1 Wednesday to approve a policy that would ban single-use plastic bags.

The ban would take effect later this year after an environmental impact report that is expected to take four months and the council adopts an ordinance.

The city's program would be modeled after bag bans in 48 other California cities.

The city would allow large stores to phase out plastic bags over six months and then provide free paper bags for another six months. Small retailers would have a year to phase out plastic.

After a year, retailers would be allowed to charge 10 cents for paper bags.

Representing the entire East Coast in impressive renewable energy stats, Boston boosted its solar power with the Solar Boston program and counts wind among its top three sources of electricity, with a turbine on city hall and more slated for several public schools. Other big plans include turning fall leaves and other yard clippings into power and fertilizer with a new biogas facility, and using recycled trash to power homes. For those residents who don't rely exclusively on the nation's most utilized public transportation systems, taxis will soon be another green option as they're all required to go hybrid by 2015. New bike lanes and 250 bike racks have increased Boston's pedal power, and the city saves a whopping $400,000 a year thanks to LED traffic lights.
