Atmospheric carbon dioxide buildup unlikely to spark abrupt climate change

There have been instances in Earth history when average temperatures have changed rapidly, as much as 10 degrees Celsius (18 degrees Fahrenheit) over a few decades, and some have speculated the same could happen again as the atmosphere becomes overloaded with carbon dioxide.

New research lends support to evidence from numerous recent studies that suggest abrupt climate change appears to be the result of alterations in ocean circulation uniquely associated with ice ages.

“There might be other mechanisms by which greenhouse gases may cause an abrupt climate change, but we know of no such mechanism from the geological record,” said David Battisti, a University of Washington atmospheric sciences professor.

Code green: Energy-efficient programming to curb computers’ power use

Soaring energy consumption by ever more powerful computers, data centers and mobile devices has many experts looking to reduce the energy use of these devices. Most projects so far focus on more efficient cooling systems or energy-saving power modes.

A University of Washington project sees a role for programmers to reduce the energy appetite of the ones and zeroes in the code itself. Researchers have created a system, called EnerJ, that reduces energy consumption in simulations by up to 50 percent, and has the potential to cut energy by as much as 90 percent. They will present the research next week in San Jose at the Programming Language Design and Implementation annual meeting.

2011 Arts & Sciences Spring Lecture: A New Dawn for Solar Energy

Meeting the demand for clean, low-cost energy in a sustainable and environmentally friendly way is one of the defining issues of our time. Solar power can be a big part of the solution; however, ensuring it is affordable and scalable requires significant scientific and engineering breakthroughs. Explore the potential of solar energy and learn how UW researchers are combining basic scientific research in chemistry and physics with the powerful tools of molecular engineering, advanced materials and device design to meet this monumental challenge. This webcast is presented by the UW College of Arts and Sciences, the College of Engineering and the UW Alumni Association. See the video at:

UW Today: Dimmable windows with solar panels could power zero-energy buildings (2/23/11)

Windows – typically a drain on a building’s energy consumption – are being re-imagined to help boost buildings’ energy efficiency. UW engineers and architects are collaborating on smart windows that can change transparency, depending on conditions, and actually harvest energy from the sun’s rays. Read more at:

Brookings Article: Around the Halls: 'Cut to Invest' at the Department of Energy (2/11/11)

The new budget request proposes growing the DOE budget by a substantial 12% over FY 2010 spending levels. R&D accounts would increase by 1/3 to about $8 billion. The outline would increase funding of the DOE’s Office of Science to $5.4 billion, on course to meet the President’s long-term commitment to double the budgets of key research agencies.

Zensi, Shwetak Patel’s Energy Monitoring Startup, Purchased by Belkin

Zensi, an energy monitoring company based on technology developed by UW CSE professor Shwetak Patel and collaborators, has been purchased by Belkin.

Zensi’s technology was licensed from the University of Washington and from the Georgia Institute of Technology, Patel’s Ph.D. institution. The technology includes single-point-of-attachment sensors for electrical power, water, and natural gas — a single sensor in a home or business uses signal processing and machine learning to identify sources and rates of consumption. This dramatically reduces the cost of instrumenting the home or business and providing occupants with the information they need to behave in more economical and environmentally responsible ways.

According to Patel, this is just the beginning for using software to help consumers better conserve energy. “This puts UW on the map as a premier place for energy work in the residential space,” says Patel.

UW to study state biomass supply

OLYMPIA — The state has picked the University of Washington School of Forest Resources and TSS Consultants to do a 10-month study of the biomass supply in state forests. The study, the first of its kind in the nation, will be funded through a $1 million U.S. Forest Service grant. It will look at what biomass is available as well as access, infrastructure and location.

Testing the Waters with Tidal Energy

Tidal power may be destined to remain a niche player in the U.S. energy portfolio, but the low-carbon energy source has one key advantage over wind and solar--it's as dependable as the moon's phases. UW professor Brian Polagye quoted in this Scientific American article. Read more at:

7 Projects Paving the Way for Ocean Power

What if we could tap the power of the ocean to produce electricity?

The University of Washington’s School of Aquatic and Fishery Scientists in Seattle will be evaluating three technologies — echo sounders, acoustic cameras and multibeam sonar — for their ability to monitor animal densities at sites where hydrokinetic projects are proposed. The team, which scored a $746,000 grant over two years, plans to deploy instruments at the site of a tidal energy demo project proposed by the Snohomish Public Utility District, in Washington’s northern Admirality Inlet.

Molecular imaging and therapy center to develop, commercialize technologies

Ultrasound, best known by many for snapping pictures of babies before they are born, could soon be a way to spot cancerous cells before a tumor develops, precisely monitor how a person responds to treatment, or deliver genetic therapies to their targets.

The Ultrasound-based Washington Molecular Imaging and Therapy Center was established this spring with a $5 million grant from the Life Science Discovery Fund. The UW center will discover, develop and commercialize new medical technologies.

UW team builds sensors that run for decades on 1 battery

Researchers at the University of Washington and colleagues at Georgia Institute of Technology have figured out a way to make electronic sensors run for perhaps 50 years on a single battery.They're starting a company to commercialize the invention, which is already attracting potential customers. Shwetak Patel, an assistant professor of computer science and electrical engineering is the PI. Read more:

UW invention could someday make gasoline obsolete (watch a video)

Technology invented by Aaron Feaver during his PhD work at the UW led to the founding of Seattle-based EnerG2 and the licensing technology that is transforming the way energy is stored. Provost Phyllis Wise called it a, "...wonderful success story."

The high-level vision for EnergG2 is to make gasoline obsolete. CEO Rick Luebbe said, "We can do that with electrical energy storage."

EnerG2 - New manufacturing plant was dedicated August 10, 2010. See the plant dedication video at:
