02/09/12 — The College of Engineering has launched a new major-driven largely by undergraduate interest-that focuses in a comprehensive way on the generation, transmission and storage of energy, with additional courses on energy policy. Beginning in fall 2012, the new interdisciplinary Energy Engineering major will be offered through the Engineering Science Program and extract from the best energy-related courses already offered by the College. “The objective of this major is to produce students who are well-rounded energy experts,” says Tarek Zohdi, mechanical engineering professor and chair of the Engineering Science Program.

Berkeley Lab research sparks record-breaking solar cell performances

11/07/11 Berkeley Lab — Theoretical research by scientists at LBNL has led to record-breaking sunlight-to-electricity conversion efficiencies in solar cells. The researchers showed that, contrary to conventional scientific wisdom, the key to boosting solar cell efficiency is not absorbing more photons but emitting more photons. "A great solar cell also needs to be a great Light Emitting Diode," says Eli Yablonovitch, the UC Berkeley professor of electrical engineering who led this research.

An engineer’s duty

04/08/11 — When disaster strikes, all of us feel compelled to respond. Japan's devastating earthquake on March 11 called forth our faculty and students to help in ways only an engineer can.

Atomic fuel stored at U.S. plants poses risks similar to Japan facilities

03/18/11 Bloomberg — U.S. nuclear power plants that store thousands of metric tons of spent atomic fuel pose risks of a crisis like the one unfolding in Japan, where crews are battling to prevent a meltdown of stored fuel, nuclear safety experts said. Nuclear plants weren't designed with the intention of storing their spent fuel permanently, said Bozidar Stojadinovic, a professor in the department of civil and environmental engineering at UC Berkeley. "The plants have always been designed with the idea that the fuel will be taken care of," Stojadinovic said. "The government promised to do that."

Lead scientist Dr. Ashok Gadgil describes the partnership between the DOE lab and several non-governmental organizations including Oxfam America and the Clinton Global Initiative. Now with help from the Office of Energy Efficiency and Renewable Energy's Technology Commercialization Fund, Dr. Gadgil is bringing his latest innovation to Ethiopian households.

Energizing the energy agenda

12/14/10 — While climate change and carbon emissions are very much in today's headlines, what is less often discussed is the need to provide technological societies with the economic imperative to make changes in our global energy system.

Thermoelectrics: A matter of material

06/03/10 — Waste heat: It's when heat produced in a combustive process goes unused, dissipating into the air or water. Automobiles, industrial facilities and power plants all produce waste heat, and a lot of it. A holy grail awaits anyone who can improve the current fossil fuel system. One estimate places the worldwide waste heat recovery market at one trillion dollars, with the potential to offset as much as 500 million metric tons of carbon per year. What's the magic solution? Some Berkeley engineers believe the answer lies not in a sophisticated device, but in materials: specifically, finding a new material with spectacular thermoelectric properties that can efficiently and economically convert heat into electricity.

Blue and gold make green in Silicon Valley

04/07/10 — Clean and green technologies are on the rise in Silicon Valley. Electric car startups like Tesla Motors and solar cell and biofuel innovators are snapping up commercial space, while established companies like Applied Materials are growing their clean energy divisions. “Over the past six years, clean tech's portion of venture [capital] investments has grown from merely 3 percent to more than 25 percent,” reported the San Jose Mercury News in January. The newspaper went on to pronounce clean and green technologies the next great wave of innovation in Silicon Valley. It's no surprise to five Berkeley Engineering alumni who work in the up-and-coming sector.

Video Feature: A low-wattage workout

04/07/10 — At UC Berkeley's Recreational Sports Facility, where Berkeley mechanical engineering students Kimberly Lau and Maha Haji work out, they noticed all those people burning calories on exercise machines. Racing on treadmills. Striding on ellipticals. Churning on stationary bikes. What if that energy could be harnessed? Could workouts be more energy wise? In this video, they explore these questions and learn how you can make greener choices at the gym.

Rethinking nuclear power

04/07/10 — What's the first thing you think of when you hear the word nuclear? Mushroom clouds? Three Mile Island's reactor towers surrounded by swirling steam? Think again. Nuclear is back, big time. With climate change concerns escalating, fossil fuel supplies diminishing and electricity consumption expected to double in 10 years, nuclear has regained some of its lost luster. According to Brian Wirth, associate professor of nuclear engineering, “The 104 nuclear plants now in operation represent the largest source of carbon-free electricity in the country.”

A Sea Change for Wind Farms

11/13/09 — Twenty miles out to sea, far from seabirds and boat traffic, a 300-foot wind turbine spins in the breeze. It's not alone. Thirty wind turbines are generating electricity in something called an offshore wind farm. Each turbine is integrated into a highly advanced floating platform and tethered by thick chains to the sea floor. Electricity flows into a giant undersea cable that extends toward shore. At 200 megawatts, this floating farm of clean energy powers more than 60,000 homes. It's still a futuristic vision, but ocean engineers and entrepreneurs Dominique Roddier (Ph.D'00 Naval Architecture) and Christian Cermelli (M.S'90, Ph.D'95 Naval Architecture) are one step closer to bringing their unique solution, WindFloat, to life.

From Bacon to Biofuel

03/02/09 — Brown grease - a nasty melange of leftover animal fat, pan scrapings and other gunky residue - is a sewer pipe's worst enemy. In San Francisco, a pilot project led by two Berkeley Engineering alumni is in the works to explore for the first time how wastewater treatment plants throughout California might turn the unappealing stuff into biodiesel fuel. "For the city, it's going to be a win-win situation," says Domenec Jolis (Ph.D.'92 CEE), a senior engineer at the San Francisco Public Utilities Commission and the project's co-principal investigator.

A Better Energy Grid for the Developing World

11/02/08 — According to the UN, lack of access to electricity and fuel in rural areas contributes to 1.6 million deaths per year and perpetuates poverty. For engineers and energy suppliers working in this environment, bringing power to these populations requires a multi-pronged effort, not just to build the grids themselves, but also to plug into the human factors of operating within a particular culture and under what is usually a cash-strapped government. Christian Casillas, a Ph.D. student advised by Professor Daniel Kammen in the Energy and Resources Group, is balancing these two sides of the problem, working out the details of a roadmap to bring reliable electricity to the fishing villages along Nicaragua's eastern coast.

Engineering Grad Brings “Fiat Lux” to Nicaragua

01/02/08 — In remote villages along Nicaragua's Caribbean coast, the seemingly simple act of switching on a light is anything but simple. It's usually impossible. Mathias Craig (B.S'01 CEE) wants to change that. Craig, 29, is cofounder of blueEnergy, a nonprofit organization that is harnessing the power of the wind to illuminate homes, schools and rural clinics in an impoverished region where nearly 80 percent of the population have no electricity. Since 2004, blueEnergy has brought wind turbines to six Nicaraguan communities, providing electricity to some 1,500 people.
