The typical American household now has 24 electronic gadgets, and those computers, game consoles and cellphone chargers are putting an ever-growing burden on the electrical grid and household bills and the state's electricity grid.

In California, electronic devices now account for 31 percent of home electricity use. And the bulk of those devices are from home entertainment systems and personal computers.

The California Energy Commission, which has led the nation in adopting energy-efficiency standards for traditional appliances like refrigerators and air conditioners, is now turning its regulatory attention to more than 15 new products, from game consoles and computer monitors to outdoor streetlights and water-using products like toilets and pool pumps.

The commission is in the early phases of setting new standards that would likely come up for a final vote next year. The process, which includes workshops with industry, utilities and environmental groups and a public comment period, typically takes 18 months.

"Energy efficiency is our No. 1 priority," said Ken Rider, an electrical engineer with the commission's appliances and process energy office. "It's the cleanest, cheapest way to take care of increased energy demand in the state."

Andrew deLaski, executive director of the Appliance Standards Awareness Project, said it makes sense for California to turn its attention to consumer electronics.

"Consumer plug

load is on the rise as traditional loads like refrigerators and dishwashers are becoming more efficient," he said. "Consumer electronics are making up a bigger piece of the home energy pie."

But the Consumer Electronics Association, whose 2,000 member companies include Silicon Valley titans like Apple (AAPL), Hewlett-Packard (HPQ) and Intel (INTC), fiercely opposes new standards and warns of "serious flaws and shortcomings" in the process, including the use of old data. The association is also urging state legislators to support a bill by Assemblyman Charles Calderon that would curtail the energy commission's authority. The trade association argues that consumer electronics change so rapidly, with new iterations of products hitting stores every six to 18 months, that regulations are onerous, quickly outdated and unnecessary. And they stress that while the number of consumer electronics per household rose dramatically in the 1990s -- from 9.7 gadgets per household in 1990 to 17.4 per household in 2000 -- the number of gadgets per home has been flat since 2005.

It also maintains that the "convergence" that collapses multiple products into one actually saves energy. The ability to check email and take photographs with a smartphone, for example, means you don't have to turn on the home computer or keep a digital camera. Many game consoles provide access to the Internet.

"The California Energy Commission makes poor assumptions about the direction of technology," said Doug Johnson, vice president of technology policy at CEA. "Convergence is a good thing for efficiency. Smartphones are now a necessity, and many products are used in ways that save energy."

San Francisco-based PG&E is generally supportive of energy-efficiency standards. The utility partnered with Best Buy's San Carlos store to create a "Home Energy Department" display within the store to educate consumers about energy-efficient products.

The state says new standards could save $7 billion each year in electricity costs, reducing the need to build more power plants and lowering water use by 70 billion gallons a year. The state also argues that efficiency standards save consumers money on their electricity bills each month.

Many environmental groups support new standards, arguing that they would not only save energy in California but also serve as a catalyst for improving the energy efficiency of products sold elsewhere. The sheer size of California often pushes manufacturers to make changes. "These standards will ensure that new products sold in California contain the latest and smartest technology so that our products sip rather than gulp energy," said Noah Horowitz, a senior scientist at the Natural Resources Defense Council.

Several popular products -- including Microsoft's Xbox, Sony's PlayStation, Nintendo's Wii, set-top boxes used with cable and satellite television sets, personal computers and monitors -- would be affected. Because the commission has not yet settled on a definition for computers, it's not clear if tablets, like the popular iPad, will be included.

energy tips for your gadgets

1. Unplug It. The simplest way to save electricity is to unplug products when they are not in use. Search the wall sockets in your house for chargers and other devices that don't need to be plugged in. When you detach your cell phone from its charger, unplug the charger too.
2. Use a Power Strip. Plug home electronics into a single power strip with an on/off switch. This will allow you to turn off power to the devices in one easy step. One caveat: home entertainment equipment such as cable and satellite boxes and DVRs need to be reprogrammed or given time to reboot and download information when turned back on. You may want to plug these devices into a separate strip and only turn them off when you plan to be away for more than a few days.
3. Enable the power management features of your computer, such as "sleep" mode.
4. Instead of using a "screen saver," let your computer turn off or go to a dark screen.
4. Use a power meter. Products like Kill A Watt and Watts Up? Pro Power Meter can be plugged in between an appliance and a wall socket to let you see how much electricity it uses. That information can guide your decisions on which appliances to unplug or replace.
