The document discusses the GreenLight project which aims to measure and reduce the energy usage of computational applications, algorithms, and architectures. It summarizes that the project focuses on minimizing energy usage for key user communities through various techniques like active power management, virtualization, and direct DC power from solar and fuel cells. The goal is to develop a "zero carbon" cyberinfrastructure through coupling optical networks between Australia, the US, and Canada to remote renewable energy sites.

ICT is a Critical Element in Achieving Countries Greenhouse Gas Emission Reduction Targets Applications of ICT could enable emissions reductions of 7.8 Gt CO 2 e in 2020, or 15% of business as usual emissions. But it must keep its own growing footprint in check and overcome a number of hurdles if it expects to deliver on this potential. www.smart2020.org
