Sept. 17, 2008 - Oil and gas giant Chevron has launched a new ad campaign plugging the benefits of energy efficiency and conservation.

The new "I Will" campaign aims to encourage people to use energy more wisely, according to Chevron vice chairman, Peter Robertson.

"Energy efficiency is the cheapest and most reliable source of new energy that we have," Robertson says. "With demand for energy continuing to rise across the United States and around the world, it’s imperative that we use the resources we already have more efficiently."

In addition to TV and print ads debuting this month, Chevron is also re-launching its campaign website, willyoujoinus.com, which provides several interactive tools that demonstrate how simple individual actions can yield measurable energy savings. For example, the site's Energy Generator demonstrates how lowering the thermostat in an average U.S. residence by one degree over the winter can save enough energy to power a reading lamp for 5,000 hours.
