Power is becoming an increasingly large financial and scaling burden for computing and society. The costs of running large data centers are becoming dominated by power and cooling to the degree that companies such as Microsoft and Google have built new data centers close to large and cost-efficient hydroelectric power sources. Studies have projected that by 2012, 3-year data center energy costs will be double that of server equipment expenditures. Power consumption and related cooling costs have become a primary design constraint at all levels, limiting the achievable density of data centers and large systems, and pushing processor manufacturers towards alternative architectures.
