Manufacturing the billions of semiconductor chips TI produces annually requires critical resources such as energy, water and other materials. The majority of the energy we use is in semiconductor manufacturing, during which many tools operate 24 hours a day. Our energy use comprises sources characterized as direct (such as natural gas used on-site) and indirect (such as electricity purchased off-site).
TI takes a holistic approach to energy efficiency and conservation, from the way it uses energy to the products it manufactures. For decades, we have invested in efficiency projects and nurtured a work culture dedicated to reducing energy consumption. Today, on average, we implement more than 100 such projects annually that help us build, operate and manufacture more efficiently. These efforts reduce our carbon footprint and collectively save an average of more than $5 million each year.
Our manufacturing operations account for about 90 percent of TI's total energy use and are the focal point for our global energy strategy, which includes efforts to:
Some of the key ways we maximize energy efficiency include:
