Our vision is to create a sustainable energy future for Arizona. To accomplish this, we must strike a balance between delivering reliable, affordable energy and being responsible stewards of the environment.
By the end of 2016, 50 percent of our diverse energy mix was carbon-free. We reached this level with a combination of traditional and renewable energy resources and energy efficiency actions.
We continue working to make that mix cleaner. These efforts include closing coal units, modernizing natural gas plants, deploying renewable energy and improving energy efficiency. Our Palo Verde Nuclear Generating Station continues to be the country’s largest source of carbon-free energy, far surpassing other energy sources for producing clean, around-the-clock power.
Our efforts to reduce our carbon footprint are not limited to energy generation. We also have made our own buildings more energy efficient and continued converting our fleet to more fuel-efficient vehicles. Through these combined efforts, APS avoided 4.9 million metric tons of carbon dioxide emissions that otherwise would have been emitted in 2016—equivalent to removing more than 1 million automobiles from the road.
In line with projected population growth in Arizona, we anticipate customer growth of approximately 45 percent by 2032, representing up to an additional 549,000 customers. We expect renewable energy and energy efficiency to meet more than 50 percent of that growth. This will help us achieve our long-term goal to reduce our carbon-emission rate to less than 600 pounds per megawatt-hour (lb/MWh) by 2032.
