In 2007, Barroso and Ho ̈lzle presented a case for energy-proportional computing that has transformed the design and energy-efficiency of computer servers and modern data centers. However, their original definition does not characterize the energy-efficiency profiles of recent highly-configurable servers, resulting in non-intuitive "super-proportional" behavior. In this talk, I introduce new definitions of "ideal" energy-proportional computing targeting both the design of new servers and optimal operation of existing ones.

For the first time in history, more than half of the world’s population lives in urban areas; in just a few more decades, the world's population will exceed 9 billion, 70 percent of whom will live in cities. Enabling those cities to deliver services effectively, efficiently, and sustainably while keeping their citizens safe, healthy, prosperous, and well-informed will be among the most important undertakings in this century.

Use of the heat from nuclear reactions to produce electricity has been proven over decades of commercial operation to be a safe and reliable large-scale carbon-free power source.  Advanced reactor designs and fuel cycles are designed to be even safer, more efficient, and produce far less waste than presently deployed commercial reactors.  Unfortunately, due to the historical regulated commercial environment in which the nuclear industry in western democracies has developed, no advanced reactors are allowed to be built and little innovation has been possible to address the primary

WiFi Display, also called Miracast, is an emerging technology that allows a mobile device (source) to duplicate its screen content to an external display (sink) via a peer-to-peer WiFi link. Despite its growing popularity and diverse application scenarios, Miracast involves a host of power hungry operations like video encoding/decoding and WiFi, which can quickly drain off a mobile device’s battery.

We invite you to a free, interdisciplinary conference of presentations and discussions on "Sustainable Science Communication" May 13 and 14, 2015. The event begins with the new documentary Merchants of Doubt and audience discussion beginning at 7 pm May 13 in the elegant Pollock Theater.

With ambitious new “renewable portfolio standards” of 50% in California by 2030 and for 20% of electricity for the entire United States by 2030, both excluding hydroelectric, the power grid faces dramatic challenges in absorbing higher levels of variability, whilst continuing to deliver reliable, cheap energy.  And with the DOE’s recent Wind Power vision indicates a 35% national RPS from wind is possible by 2050, the challenge continues beyond these nearer term goals.

A small, covert team of engineers at Microsoft turned one of the largest corporate campuses in the world into a “smart campus” achieving energy and operational savings. By applying an “Internet of Things meets Big Data” approach, the team refined a data-driven software solution that is slashing the cost of operating the campus’ 125 buildings. The software, which is saving Microsoft millions of dollars, has been so successful that the company and its partners are now helping building managers across the world deploy the same solution.

Printed organic electronics, a technology based on carbon-based semiconductors that can be processed into thin films using conventional coating and printing techniques, has been the subject of active research over the past decades. Due to their ability to be processed at low temperature, over large areas, at low cost, carbon-based semiconductors can lead to a new generation of energy-efficient products using energy-efficient manufacturing approaches.

The need for improving security standards for electric power systems is well recognized.  Such efforts however, are hindered by lack of decision support tools that can incorporate security into the decision making process. The current practice is to protect the system against known or anticipated failures either by using a post-processing phase or by explicit enumeration of the known cases.

In the past decade, polymers and small molecule thin films have found use in organic electronics as organic FETs (OFETS), photovoltaics (OPV) and LEDs (OLEDS). The way the organic molecules pack and the nanoscale morphology of these films (which is often different than in bulk) have a strong impact on the film functionality. To determine this structure and relate this to the film functionality, we have used grazing-incidence X-ray diffraction (GIXD) and small X-ray angle scattering (SAXS).
