Andy Woods - Cooling the Data Center
What can be done to make cooling systems in data centers more energy efficient?

David J. Brown, Charles Reams - Toward Energy-Efficient Computing
What will it take to make server-side computing more energy efficient?

Eric Saxe - Power-Efficient Software
Power-manageable hardware can help save energy, but what can software developers do to address the problem?
