The impact of Facebook's PHP code on the environment

Facebook provided information related to the server size a month ago. they used about 30 thousand servers, and most servers run PHP code to generate users' social websites. Driven by climate change discussions in Copenhagen: how much carbon will these servers generate? How much carbon dioxide emissions will be reduced if PHP code is replaced by other languages?

The power of a server is about 200 watts, and the cooling and other costs are about 400 watts. In the United States, 560 grams of carbon dioxide is generated on average per kilowatt-hour, and Facebook servers generate tons of carbon dioxide each year. If there are about servers running PHP code and C ++ code is used to replace PHP code, the efficiency of C ++ code is 10 times that of PHP code, around 22 500 servers can be shut down, which will reduce tons of carbon dioxide emissions. Of course, this is a bit unfair to Facebook. their servers only account for a small portion of the total number of servers running PHP code around the world.
