In 2007, Google set a goal to be carbon neutral in 2023 which has been revised to 2030. In order to achieve this goal, the company has been investing in a range of energy sources, including geothermal, nuclear and renewables to power its datacentres which account for 95.8% of the company’s ‘s electricity usage.
It has agreed to buy 200MW from a nuclear fusion startup called Commonwealth 
Fusion Systems (CFS). CFS, which has raised investment of $2 billion, intends to complete a demo fusion plant next year (pictured) which is intended to show that more energy can be produced from fusion than is put in. If successful, CFS will bring a commercial fusion power plant online in Virginia in the early 2030s capable of generating 400 MW of power.
It has also agreed to buy 500 MW of nuclear fission energy from startup Kairos Power.
It has a partnership with NV Energy of Nevada and Fervo Energy to increase geothermal power supply to its Nevada datacentres from 3.5 MW to 115 MW over about six years and is investing in Fervo’s geothermal projects including one in Utah expected to deliver 400 MW by 2026-2028.
It bought 1300 MW of solar energy in the first half of 2025.
In 2024, it invested $20 billion with Intersect Power and TPG Rise Climate to build carbon-free power plants.
