According to a new study by the US Geological Society, fallen autumn leaves contribute as much mercury to the environment as precipitation. This is significant because precipitation was previously the major route for hazardous mercury in the air to be deposited to the environment. Most of the mercury in fish and food webs come from [...]
If you want to save energy and cut greenhouse gas emissions then focus on urban water conservation. That’s according to a new report entitled Drops of Energy: Conserving Urban Water in California to Reduce Greenhouse Gas Emissions (May 2011). The policy paper was produced by the UC Berkeley School of Law’s Center for Law, Energy [...]
On Monday, the media reported on a new study by the U.S. Geological Survey detailing the consequences of a winter ‘superstorm’ scenario that would strike the US West Coast and produce precipitation levels exceeding those experienced on average once only every 500 to 1,000 years.

When you’re submitting a bid to replace the KC-X aerial refueling tanker at $29.55 billion for 179 airplanes, every second counts. Literally and figuratively. Unfortunately when your bid is 5 minutes late and is disqualified, it works out to $5.91 billion per minute. That’s what allegedly happened to Los Angeles-based US Aerospace and its Ukrainian [...]
Today, the National Renewable Energy Laboratory based in Golden, CO released the Western Wind and Solar Integration Study. The goal of the study is to better understand the costs and operating impacts due to the variability and uncertainty of wind, photovoltaic, and concentrated solar power. The study found that a 35-percent target for wind and [...]
