Google disclosed in September 2011 that it "continuously uses enough electricity to power 200,000 homes", almost 260 million watts or about a quarter of the output of a nuclear power plant. Total carbon emissions for 2010 were just under 1.5 million metric tons, mostly due to fossil fuels that provide electricity for the data centers. Google said that 25 percent of its energy was supplied by renewable fuels in 2010. An average search uses only 0.3 watt-hours of electricity, so all global searches are only 12.5 million watts or 5% of the total electricity consumption by Google.
Google's initial public offering (IPO) took place five years later, on August 19, 2004. At that time Larry Page, Sergey Brin, and Eric Schmidt agreed to work together at Google for 20 years, until the year 2024. At IPO, the company offered 19,605,052 shares at a price of $85 per share. Shares were sold in an online auction format using a system built by Morgan Stanley and Credit Suisse, underwriters for the deal. The sale of $1.67 billion gave Google a market capitalization of more than $23 billion.

More InfoGoogle data centers are located in North and South America, Asia, and Europe. There is no official data on the number of servers in Google data centers; however, research and advisory firm Gartner estimated in a July 2016 report that Google at the time had 2.5 million servers. Traditionally, Google relied on parallel computing on commodity hardware like mainstream x86 computers (similar to home PCs) to keep costs per query low. In 2005, it started developing its own designs, which were only revealed in 2009.
More InfoIn 2003, after outgrowing two other locations, the company leased an office complex from Silicon Graphics, at 1600 Amphitheatre Parkway in Mountain View, California.

Caesar Sengupta, VP for Google's next billion users, told The Verge that 15,000 people get online for the first time thanks to Google Station and that 3.5 million people use the service every month. The expansion meant that Google was looking for partners around the world to further develop the initiative, which promised "high-quality, secure, easily accessible Wi-Fi". By December, Google Station had been deployed at 100 railway stations, and in February, Google announced its intention to expand beyond railway stations, with a plan to bring citywide Wi-Fi to Pune.
