Google explains how to use carbon-free clean energy by 2030

Google carbon free


Google published an extremely ambitious plan on I/O,The goal is to completely switch to carbon-free clean energy by 2030. A company can achieve the goal of carbon-free in several different levels. The most basic is to buy carbon rights to replace its own carbon output. If it is more advanced, it is when there is excess green energy production (such as solar energy in the daytime, or (Wind power when the wind is strong) sells electricity to the grid in exchange for power support from the grid when production is insufficient. Although this can also be said to be “full use of green energy,” in fact, the electricity supported by the grid may still be thermal power generation.

Google’s current goal is to use clean energy “all the time”, which means that Google uses completely clean electricity at all times. At present, Google has five data centers that almost meet the standards, and 90% of its electricity is completely carbon-free, including the latest data center in Denmark. There, Google built five solar power plants, and Denmark itself is a country with a lot of wind resources.

However, there are also some data centers in more remote places, it will be more difficult to achieve the goal. Therefore, while building more green energy power plants, Google will also use AI to control the load between data centers, and put services that require more computing power (such as Photos and YouTube transcoding) into current data with a high percentage of green energy. The center, or in a data center dominated by solar energy, schedules most of the work to the daytime, and uses the existing green energy as much as possible.
