Don't forget to 'spring forward' Sunday 

After a few weeks of morning sunlight, San Francisco’s early risers will be back in the dark Sunday morning as the new daylight-saving time goes into effect. (Will you need to download an update to keep your computer on track?)

As an energy-saving measure implemented in 2005 by President Bush, the new daylight-saving time adds an hour of daylight for four extra weeks each year. Normally, daylight-saving time is April through October, but now it will take place in March through November.

According to the California Energy Commission Web site, the average home uses 25 percent of all the electricity for lighting and small appliances. A good percentage of energy consumed by lighting and appliances occurs in the evening when families are home, and adding one hour of daylight can cut the amount of electricity consumed.

Hillard Huntington, executive director of energy modeling forum at Stanford University, said the change has potential to save consumers a little money, but comes at a time where alternative methods of energy need to start being considered more seriously.

As of yet, Pacific Gas and Electric Co. spokeswoman Melissa Mooney said PG&E couldn’t estimate immediate changes in local energy bills, but the company is reviewing the impacts of the early daylight-saving time on customers.

"Daylight-saving time provides a great opportunity to re-emphasize the significant environmental benefits created by energy efficiency," Mooney said.

There has also been buzz that the change will have a catastrophic impact on computers that were made before 2005 — but Steven Ostrowski, director of corporate communications for the Computing Tech Industry Association, said Y2K-like panic is unfounded.

"Normally people with newer machines are in good shape — but if you don’t have a newer machine, the most you’ll have to worry about is resetting the time. This is more in the annoyance and aggravation category than catastrophe," Ostrowski said.
