The article states, "Across Africa,... Read More
Prices for wind energy have hit rock bottom, thanks to technological advances and learning. Are the opportunities for significant additional cost reductions tapped out, or are much-lower costs still possible? Recent research by Berkeley Lab suggests that some energy planners, analysts, and policymakers may be underestimating both the potential for and uncertainty in wind energy cost reductions. The consequence may be under-prediction of wind... Read More
EAEI researchers Jeff Greenblatt and Max Wei are quoted in an October 6, 2016 article in Christan Science Monitor on methane emissions from fossil fuels.
Two factors that contributed to the poisoning of tens of thousands of Washington, D.C., residents through their drinking water in the early 2000s—lead pipes and a disinfectant called chloramine—continue to coexist in countless water systems nationwide, including in the Bay Area. But not to worry, says UC Berkeley water expert and engineering professor David Sedlak; they’re safe when properly managed, which happens in the vast majority of public... Read More
Few would argue that the state hasn't done its fair share in the fight against climate change. But the question of how much the Global Warming Solutions Act has actually cut California's greenhouse gas emissions is tougher to get at. "I think that it worked," says the Lab's Jeffrey Greenblatt.
Technology advancements are expected to continue to drive down the cost of wind energy, according to a survey of the world's foremost wind power experts led by Lawrence Berkeley National Laboratory (Berkeley Lab). Experts anticipate cost reductions of 24%-30% by 2030 and 35%-41% by 2050, under a median or 'best guess' scenario, driven by bigger and more efficient turbines, lower capital and operating costs, and other advancements (see Figure 1...

When an individual utility customer decides to add rooftop solar to their home or business, the utility needs to deliver less power to that customer from other sources. A small number of solar adopters may not have much of an impact, but rapid growth in rooftop solar in some parts of the country has the potential to significantly impact the need for generating resources and transmission and distribution (T&D) infrastructure.
To account for... Read More
Two new Berkeley Lab studies find record low prices across all sectors
Solar energy system pricing is at an all-time low, according to the latest editions of two recurring “state of the market” reports released today by the Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley Lab).
Within the market for distributed solar photovoltaic (PV) systems, installed prices in 2015 declined by $0.20-per-watt (W) or 5% year-over-year for... Read More
Wind energy pricing remains attractive to utility and commercial purchasers, according to an annual report released by the U.S. Department of Energy and prepared by the Electricity Markets & Policy Group at Lawrence Berkeley National Laboratory. Prices offered by newly built wind projects are averaging around 2¢/kWh, driven lower by technology advancements and cost reductions.
"Wind energy prices—particularly in the central United States—are... Read More
Berkeley Lab study identifies two additional carcinogens not previously reported in e-cigarette vapor.
While previous studies have found that electronic cigarettes emit toxic compounds, a new study from Lawrence Berkeley National Laboratory (Berkeley Lab) has pinpointed the source of these emissions and shown how factors such as the temperature, type, and age of the device play a role in emission levels, information that could be valuable to...

In the mid-2000s, William Fisk, a senior scientist at Lawrence Berkeley National Laboratory, stumbled upon two obscure Hungarian studies that challenged common assumptions about the air indoors. The studies suggested that, even at relatively low levels, carbon dioxide could impair how well people thought and worked.
Fisk, an indoor–air quality expert who led the UC Berkeley Lab’s Indoor Environment Group, searched for other studies on the topic... Read More
LBNL is collaborating with ClimateWorks on defining metrics for tracking changes in energy efficiency progress, measuring impacts and assessing strategic opportunities. This report provides a detailed description of the indicators selected. The authors considered a wide range of indicators drawing upon the literature,... Read More
A major new initiative tackles water-energy issues in California and beyond.
Billions of gallons of water are used each day in the United States for energy production—for hydroelectric power generation, thermoelectric plant cooling, and countless other industrial processes, including oil and gas mining. And huge amounts of energy are required to pump, treat, heat, and deliver water.
This interdependence of water and energy is the focus of a... Read More
A new report outlines the challenges and opportunities for the state’s 200 isolated communities that pay some of the highest electricity and heating costs in the nation. Peter Larsen of the Energy Technologies Area, was among the study’s authors.
As climate change disrupts weather patterns, many countries face swamping along the coasts, but also shrinking freshwater supplies in many regions. The Lab’s Ashok Gadgil is the principal investigator on the U.S. side of a new $64 million collaboration between China and the United States to develop strategies and technologies to conserve water in energy production and use.
A start-up team, including Dr. Hanna Breunig of the Sustainable Energy Systems group at LBNL, was recently accepted into the Bay Area regional NSF Innovation Corps (I-Corps™), a program designed to help start-ups conduct customer discovery. Torq3, the start-up team, is developing new configurations of the Halbach Array Electric Motor (HAEM) to make them more powerful and energy efficient. Improving these characteristics will allow the new... Read More
Automated vehicles can both drive more efficiently and be designed to be lighter, saving energy. However, the convenience of not having to pay attention on the road may lead people to use them more, increasing energy consumption. Which effect will tend to prevail? ETA’s Jeff Greenblatt seeks to answer that question in a blog posted on... Read More
