Google has continued to focus on being carbon neutral since 2017, becoming carbon neutral in 2007, and balancing all power consumption with buying clean energy. Devices like Nest speakers and displays use recycled plastics in their manufacture. Google continues to make improvements in this area. At Google I / O 2021, the company announced more cleaner energy initiatives with a goal of working with carbon-free energy by 2030.

One of the ways Google is looking to achieve its carbon-free efforts is through the use of carbon-conscious computing. The brand will use certain data centers for certain tasks, depending on the availability of carbon-free energy sources. This means that the data centers can take advantage of times and cases when carbon-free energy sources are more readily available and postpone tasks to use more of the clean energy that is already available. Google says this should be applied to media processing first – YouTube, Photos, Drive, etc. All of this happens in the background so that users can continue to use their applications as normal.

Another way Google wants to achieve its carbon-free initiative is to use geothermal energy. The search company announced a geothermal project to add carbon-free energy to the electrical grid that powers its Nevada data center, including the newer Las Vegas cloud region. The aim is to use the advantages of "next generation geothermal energy". His blog states: "By using advanced drilling, fiber-optic logging and analysis techniques, next-generation geothermal energy can unlock a whole new class of resources."

Google has partnered with Fervo, a clean energy startup, to improve next-generation geothermal production. It is therefore more efficient to obtain this form of clean energy, since geothermal energy generation has traditionally been somewhat limited by cost and location problems in production. Google's partnership with Fervo helps because Fervo can run fiber optic cables in wellbores to collect real-time data and figure out how to conserve the best possible resources. Combine that with machine learning and A.I. (which Google specializes in) and this can potentially work wonders for geothermal power generation.
