It might be a marriage made on the farm .. with data centers being located in rural areas that have lots of farms using manure to power data centers is a way to be green
"Data centers need a lot of energy. Dairy farms create a lot of methane. … HP Labs has done the math to show that one could be used to support the other."
" … data centers … increasingly being located near existing power generation or cooling resources. … untapped source of energy, however, is the methane generated by manure on farms around the world."
" … HP … paper shows how a farm of 10,000 dairy cows could … power a typical modern data center and still support other needs on the farm."
" … turning data centers from being energy hogs into energy neutral facilities … goal … see if we can take the data center completely off the grid."
