“Exotic Behavior” Shines a Light on Piezoelectricity

Tina Casey — Sat, 14 Nov 2009 14:40:04 +0000

A team of researchers from UC Berkeley and the U.S. Department of Energy’s Lawrence Berkeley Lab have discovered a new lead-free material that produces an electrical current when exposed to stress. The phenomenon, called piezoelectricity, sounds exotic but it could some day become as common as backyard grills.

Piezoelectricity is a sustainable way to generate energy. It works by applying pressure or stress to certain crystalline materials, including certain ceramics and even bone, so it’s a green alternative to burning fossil fuels. Up to now, though, the most popular piezoelectric materials contain lead, a notorious neurotoxin. The discovery of a lead-free material could open the door to a piezoelectric energy future in which people generate significant amounts of electricity just by moving through the civic infrastructure, from highways to flooring and revolving doors.

UC Berkeley Report Says Global Warming Could Put $2.5 Trillion of California Real Estate at Risk

A new report says that global warming could cost the Californian economy billions of dollars each year, through a combination of rising sea levels, and the increased frequency of wild fires and extreme weather events.

The comprehensive study (PDF), published by researcher’s at UC Berkeley, also claims that $2.5 trillion of Californian real estate assets are at risk. The clear message, says co-author Prof. David Roland-Holst, is the strong economic case for timely action to slash carbon emissions and adapt to the already unavoidable effects of climate change.

“Our report makes clear the most expensive thing we can do about climate change is nothing,” he said. “As we learned in New Orleans, turning your back on the threat of natural disaster doesn’t make it go away.”

Energy Efficiency Policies and Products Create Jobs

In this uncertain economic time, it is great to hear some good (and not just on a relative scale, but really good) news. A just-released report authored by UC Berkeley professor David Roland-Holst, called “Energy Efficiency, Innovation, and Job Creation in California,” documents the job growth and economic development that resulted from thirty years of policies enacted in California to encourage residents to adopt energy efficiency measures.

A summary by the author David Roland-Holst on the sponsor (Next 10’s) site, documents that there is wealth to be created in reducing greenhouse gases and improving the environment. You can also download an executive summary or full report via that link.

The report shows that there were job losses in a few sectors due to energy efficiency policies, but it also lists over a dozen industries where the employment gains were significant. The net result is

How a Random Guy Trumped the Greatest Minds from China and the USA on Climate Change

Gavin Hudson — Sat, 02 Aug 2008 03:22:03 +0000

In May of 2006, I had the chance to attend the China-US Climate Change Forum hosted by the University of California at Berkeley. To an eco-geek, the list of speakers was star-studded with Nobel laureates, professors from top universities, famous innovators, and leaders from the business communities in China and the United States. The conference opened with the premier of Al Gore’s An Inconvenient Truth, just before it hit theaters. Before a university worker’s strike altered plans, Al Gore himself was slated to join the stage.

But it was a random guy in the audience who stole the show with a single insightful comment in the closing moments.
