IBM India To Cut Data Center Emissions 40% With Solar PowerClean Technica, December 20, 2014
An IBM data center in India plans to cut is greenhouse gas emissions by 40% using solar power and water cooling for air conditioning. The Bengaluru-based data center uses a 50 kW solar photovoltaic system that provides electricity to the data servers.
The DC power generated by the solar panels is directly fed to the servers converting it into AC supply. This helps cut power losses by 15%, which, in turn, also cuts GHG emissions. Cold water flowing through the server mainframe takes away the heat generated by its various components.
The solar power system serves a dual purpose. It provides a free and virtually uninterrupted supply of electricity and offsets GHG emissions as well. Continuous power supply remains an issue even in Bengaluru, India’s IT capital. An increasing number of companies are now looking to set up their own solar power plants – rooftop or utility-scale – to meet their demands. The need for this in-house generation has also stemmed from the expected trend of increasing electricity tariff.
