saving energy and reducing greenhouse gas emissions

Energy-saving consumers can make a real difference

Two weeks ago, we described some of the steps ExxonMobil is taking to address the risk of climate change. These included working to improve energy efficiency and fuel economy, and groundbreaking research into low-emissions technologies.

This week, we focus on consumers. About 40 percent of all energy-related carbon dioxide emissions in the U.S. — more than 2.3 billion metric tons annually — comes from consumers using energy at home or on the road. So the combined energy-saving efforts of many individuals can make a real difference.

Here are some simple steps to consider:

Be smart about electricity use.
Electricity accounts for 70 percent of carbon dioxide emissions attributed to homes in the U.S. Saving electricity helps reduce emissions. In fact, if every home in the U.S. used 10 percent less electricity, the carbon dioxide emissions saved would be like taking 15 million cars off the road. Turn off unnecessary lights. Replace incandescent bulbs with more efficient compact fluorescent lamps, lasting six to ten times longer. Turn off TVs, computers and other equipment when not in use. And choose appliances labeled "Energy Star," which meet government efficiency guidelines.

Heat and cool your home efficiently.
Nearly half of a home's energy bill covers heating and cooling. Reduce energy waste by installing adequate insulation, plugging leaks, and checking for open fireplace dampers. Clean air filters regularly and service heating and cooling units annually. Set your thermostat comfortably low in the winter and comfortably high in the summer, or consider a programmable thermostat adjusted to your schedule.

Improve your gas mileage.
Vehicles account for about half the carbon dioxide emissions resulting from energy use by consumers. Improve your mileage by avoiding aggressive driving, clearing your car of extra weight, and performing scheduled maintenance such as changing air filters and properly inflating tires. For longer-term savings, consider a more fuel-efficient vehicle for your next purchase.
