Emissions of methane—a potent climate-warming gas⎯may be roughly twice as high as officially estimated for the San Francisco Bay Area. Most of the emissions come from biological sources, such as landfills, but natural gas leakage is also an important source, according to a new study from the Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley Lab).
The report by EAEI researchers Seongeun Jeong and Marc Fischer is the first to... Read More
India has announced a target of increasing the total renewable energy (RE) installed capacity from about 34GW in 2015 to 175GW by 2022 (including 100GW solar and 60GW wind capacity). This study assesses the technical feasibility of integrating 175 GW of renewables capacity in the Indian electricity grid, ascertains its impact on power sector investments and operations, and quantifies the incremental cost of such large-scale RE grid integration....

Many residential and commercial buildings leak air like sieves, wasting up to 40% of their heating and cooling energy. The primary reason for this energy loss is gaps and holes that exist in buildings’ air ducts. Getting an airtight seal on every connection can be difficult; even with skillful installation and generous applications of mastic (the putty... Read More

In the Nature article, "Can Wind and Solar Fuel Africa's Future?" IES' Grace Wu and Ranjit Deshmukh are quoted and their research highlighted on planning renewable-energy zones in Africa. "'The study is the most comprehensive mapping effort so far for most of those countries', says Wu."
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...
