To show its commitment to the Climate Savers Computing Initiative and to respond to some critics who say that a search uses a lot of energy, Google reported about its energy efficient data centers. Google compared the amount of energy consumed by doing a Google search to the amount of energy consumed by Google to answer a search query. Google claimed that the amount of energy used by its data centers is half of the energy used by a typical data center.
Specifically, the energy used by Google to answer a query is only around 1kJ (0.0003kWh) of energy. In addition, Google also claims that web searches often take the place of more carbon-and time-intensive activities, such as driving a car or navigating through the throngs of shoppers in a busy shopping mall.
