In 2017, we made long-term 2 Carbon emissions equivalences calculated using 2021 data from 100 percent renewable since opening June 2010 commitments to five more solar projects in North Carolina, the U.S. Energy Information Administration: www.eia.gov/electricity/ We used over 2. 14 billion kWh of electricity in 2022 to for an additional 85 m egawatts of clean energy. In 2022, sales_revenue_price/pdf/table5_a.pdf . power our data centers and colocation facilities around Between 2011 and 2015, we installed 68 m egawatts of 3 Emissions avoided are calculated using the GHG Protocol the world. We’re proud that 100 percent of that electricity Apple-created projects: two 20-megawatt solar projects, the Maiden data center was supported by projects that methodology for calculating market-based emissions. came from clean, renewable sources including solar, wind, an 18-megawatt solar project, and 10 m egawatts of generated 432 m illion kWh of renewable energy, which biogas fuel cells, and low-impact hydropower. To cover biogas fuel cells. We then worked with the local utility, is equivalent to the energy used by over 11,000 homes Duke Energy, to help build five solar projects through its in North Carolina for a year. 2 Use of renewable energy our needs, we build our own renewable power projects allowed us to avoid over 171, 000 m etric tons of CO e and work with utilities to purchase clean energy from Green Source Rider program. These solar projects came 2 online beginning in 2015 and were Duke Energy’s first during the fiscal year. 3 locally obtained resources. We’re staying at 100 percent even as Apple’s data center presence continues to grow. Green Source Rider projects to become operational. We worked with Duke Energy for several years to develop The energy efficiency measures we’ve implemented at We now operate eight data centers, and more are being this green energy tariff option, which allowed Apple and our Maiden data centers include use of outside air cooling developed. These data centers are spread across North Duke Energy to develop new renewable energy projects. through a waterside economizer during night and cool- America, Europe, and Asia.
