We’ve continued to pursue innovations in how we Apple-created renewable Colocation and distribution facility vendors supply about create and use renewable electricity, including through sources account for 3. 2 percent of our total load of renewable energy.

These purchases are subject to the same technologies.

This project supports the 130-megawatt California Flats solar Supporting social impact farm, which provides most of our renewable energy in We launched our Power for Impact program in 2019 California, by storing excess energy generated during the to help provide local communities with needed energy day and deploying it when it’s most needed. resources. With funding from Apple, local communities and organizations gain access to cost -effective We’re also continuing to support biological methanation energy. At the same time, Apple retains the projects’ research at Aarhus University, Denmark, which explores environmental attributes, benefiting the community, the production of synthetic methane for storage in the our company, and the environment. Apple is currently existing gas grid. In this process, bacteria consumes supporting 20 renewable electricity projects around the both hydrogen produced from excess renewable energy world, including in the Philippines, Thailand, and South and captured carbon dioxide to produce methane, the Africa.

Methane produced from renewables is a versatile energy carrier that can be used as a fuel source in households, industry, and transportation. Apple has invested in the California Flats energy storage project, which retains generated clean energy from intermittent renewable sources, including the adjacent 130-megawatt California Flats Solar Project (pictured).
