Differences in local market conditions and policies, and other factors, particularly the size of the system, can lead to wide disparities in what consumers across the United States pay to install solar energy systems on their homes or small businesses. This translates into thousands of dollars difference in the price of comparable solar energy systems around the U.S.

Ever wonder what’s in the black cloud that emits from some semi trucks that you pass on the freeway? Lawrence Berkeley National Laboratory (Berkeley Lab) scientist Thomas Kirchstetter knows very precisely what’s in there, having conducted detailed measurements of thousands of heavy-duty trucks over months at a time at two San Francisco Bay Area locations.

New Research Quantifies Health Benefits of Reducing Greenhouse Gas Emissions

Reducing greenhouse gas emissions (GHG), which result from the burning of fossil fuels, also reduces the incidence of health problems from particulate matter in these emissions, according to Berkeley Lab researchers and colleagues. They calculated that the economic benefit of reduced health impacts from GHG reduction strategies in the U.S. range between $6 and $14 billion annually in 2020, depending on how the reductions are accomplished.

Berkeley Lab Report Quantifies the Financial Impacts of Customer-Sited Photovoltaics on Electric Utilities

A new report prepared by analysts from Berkeley Lab examines the potential impacts of customer-sited solar photovoltaics (PV) on electric utility profitability and rates. The report shows that these impacts can vary greatly depending upon the specific circumstances of the utility and may be reduced through a variety of regulatory and ratemaking measures.

Interactive Map Reveals Rooftop Reflectance for Five California Cities

The price of solar energy in the U.S. continues to fall substantially, according to the latest editions of two annual reports produced by Berkeley Lab. A third Berkeley Lab report, written in collaboration with researchers at Yale University, the University of Texas at Austin and the U.S. Department of Energy (DOE), shows that local permitting and other regulatory procedures can significantly impact residential photovoltaic (PV) prices.

Wind energy pricing is at an all-time low, according to a new report released by the U.S. Department of Energy and prepared by Berkeley Lab. The prices offered by wind projects to utility purchasers averaged just $25/MWh for projects negotiating contracts in 2013, spurring demand for wind energy.

Still a Lot to Learn About India’s Deadly Air Pollution

There is still a lot that scientists don’t know about air pollution, but the severe pollution common in much of India offers scientists an opportunity to better understand its causes and effects. Lawrence Berkeley National Laboratory researcher Josh Apte is developing some unique approaches to studying air pollution in India and hopes to apply what he learns to developing global strategies for combating it.

The world’s most advanced energy efficiency test bed for buildings is open for business, launched today by U.S. Department of Energy Deputy Secretary Daniel Poneman. FLEXLAB is already signing up companies determined to reduce their energy use by testing and deploying the most energy efficient technologies as integrated systems under real-world conditions. The facility includes a rotating test bed to track and test sun exposure impacts, and other high-tech features.
