Yahoo, Hewlett Packard and International Business Machines (IBM) have won a multimillion US government fund to finance a number of energy-efficient projects.
The companies secured around $20 million (£12.5 million) for energy efficient data processing, storage, telecommunications and other business energy projects.
Yahoo plans to use its $9.9 million to design a data centre system that makes use of outside air for cooling to enable power and water to be used much more efficiently.
IBM received around $4 million, which it will use to develop software to improve air conditioning and systems which use outside air at computing facilities to reduce energy dependency.
The firm will also use its funding to develop a system that transfers heat out of data centres and reduces the use of cooling energy.
Meanwhile, HP's $7.4 million will be used to test the creation of a system that connects data centres with alternative renewable energy sources such as wind and solar power.
