TI's key energy-related achievements during the year included:
Additionally, we continued to work to integrate new facilities into our production flow. We purchased three additional manufacturing sites in late 2011; these were included in our metrics for the first time in 2012.
- Assessing the top 820 energy-saving practices across various systems in 22 facilities worldwide, to identify opportunities for improvement and share best practices.
- Completing comprehensive energy assessments at five sites and identifying several conservation projects. Engineers performed these assessments in Maine, Scotland, California, and at two sites in Malaysia. Four of those sites were former National Semiconductor sites. This supported our goal of integrating those factories into TI's energy programs.
- Joining the U.S. Department of Energy's Better Plants program and committing to reducing our energy intensity at U.S. manufacturing sites by 25 percent in 10 years. This means we will use 25 percent less energy to complete the same manufacturing tasks.
- Our 2012 goal was to implement energy-saving projects that reduced utility costs by $6 million. We greatly exceeded that goal and realized an annualized savings of $7.9 million through 181 energy-efficiency projects that prevented 46,000 metric tons of carbon dioxide from entering the atmosphere.
- Although it takes a fairly small amount of energy to manufacture a single semiconductor chip, we manufacture billions of chips each year. That's why we set a goal in 2010 to reduce the energy required to design, market and manufacture a chip by 45 percent by 2015. After two years of working toward this goal, our normalized energy use decreased by 4.3 percent. This figure improved by 13.6 percent compared to 2011, and will continue to improve as our recently added factories become more fully loaded, which enables greater efficiency in operations.
- Our overall energy use globally was 11.2 million British thermal units (MMBTUs) or 3,295 million kilowatt hours, which comprised about 66 percent of our carbon footprint. This was a 5 percent increase from 10.7 million MMBTUs or 3,123 million kilowatt hours in 2011. The increase was due to the addition of three factories and one large office complex following the acquisition of National Semiconductor in late 2011.
- We continued sourcing 10 percent of the electric power used by our sites in Texas – including our headquarters – from wind power, which helped reduce our carbon footprint. Our Texas sites account for nearly 50 percent of our worldwide electricity use. The worldwide renewable energy we purchased was 20.1 percent of our total electricity purchases. We purchased 4.3 percent from the Panther Creek Wind Farm in West Texas, and 15.9 percent as part of our grid power mix, primarily from hydroelectric power plants.
TI's plans for 2013 will be to:
- Implement site-specific projects that incorporate best sustainability practices to reduce energy use and improve operational efficiencies.
- Continue implementing energy-saving projects that will reduce utility costs by $8 million.
