2020 Emerging Technologies Review - Day 1: Energy Efficient Cloud and Data Center Workshop

In this special year, The Institute for Energy Efficiency at UC Santa Barbara held three virtual workshops as part of the 2020 Emerging Technologies Review.

The ETR virtual workshops covered new developments in: Energy Efficient Clouds and Data Centers on October 2nd; Smart Societal Infrastructure on October 16th; and Food-Energy-Water on October 23rd. Each virtual workshop featured world class experts and leaders in that arena from industry, academia and government.

Upcycling Plastic into Useful Molecules

The current scale of plastics production and the accompanying waste disposal problems represent a largely untapped opportunity for chemical upcycling. Tandem catalytic conversion by platinum supported on γ-alumina converts various polyethylene grades in high yields to liquid alkyl aromatics in the absence of added solvent or molecular hydrogen. These molecules can be used as biodegradable detergents. Coupling exothermic hydrogenolysis with endothermic aromatization renders the overall process thermodynamically accessible despite the moderate reaction temperature.

Perpetual Computing: Technologies for Banishing Batteries

The energy efficiency of computing has improved by a factor of more than a trillion since the electronic computer was invented.  This astounding energy efficiency scaling is creating the opportunity for battery-free sensing and computing systems that are powered by radio waves and other ambient energy sources.  Such devices can be implanted inside the body, permanently built into structures, or deployed at scales where batteries and wires are infeasible.  I will describe my group’s work aiming to enable battery-free, perpetual sensing and computing systems.  I will descr

Data Center Energy Analysis: Past, Present, and Future

Data centers consume 1-2% of the world’s electricity, and concerns about their energy use are growing as the world becomes increasingly interconnected and digitalized. Few data center operators publicly report electricity use, necessitating the use of mathematical models for generating the sector-level energy use estimates that guide public policy and shape public perceptions.
