Excerpts:
A new tool has been created by researchers at Purdue University that is able to detect flaws in lithium-ion batteries while they are still being manufactured, potentially greatly improving the quality and reliability of the batteries and also cutting down on waste/inefficiency. Specifically, the new tool is able to flag defects and inconsistencies in the thickness of electrodes that can limit the battery’s life and reliability. As a result of the inconsistencies being spotted right … Read More

Commercial production of solar windows, using the patented SolarWindow spray-on solar power coating system, may be just around the corner. A recent announcement from US building integrated photovoltaics (BIPV) developer New Energy Technologies Ltd. (which we’ve been following for years) has us feeling that the time may soon come. As per New Energy Technologies’ recent announcement, the big news is that the fabrication time of the technology has been greatly reduced. The fabrication process, which … Read More

If you have any doubts about solar power’s place in the U.S. energy landscape, check out the new report from the Solar energy Industries Association (SEIA). Titled “Enlisting the Sun: Powering the U.S. Military with Solar Energy,” the report details solar power systems at Army, Navy, and Air Forces in more than 31 states and Washington, D.C. that add up to more than 130 megawatts. Though not a great deal relative to the Department of … Read More

This article first appeared on Mosaic by Rosana Francescato There's been a lot of talk lately about net metering. What's so special about net metering, and why all the fuss? Net metering is a simple concept that's policy in 43 states. It's like rollover minutes on a cell phone bill — it lets utility customers who install solar systems feed energy they generate into the grid if they don't need it at the time they're generating … Read More

The idea of an “artificial leaf” sounds simple enough: Take a small, cheap, light-collecting device the size of a typical leaf, dunk it in a quart of water, and use solar energy to generate enough hydrogen gas for powering a small fuel cell. Scaled up, these solar-derived fuel cells would provide an energy storage solution that puts solar power on the same consistent, reliable footing as any fossil fuel. Various researchers have gotten most of … Read More

This article originally appeared on RenewEconomy. By Sophie Vorrath Ever since the US saw its CO2 emissions hit a 20-year low last year, the widely held belief has been that natural gas played the dominant role by pushing coal out of the market. But, as Stephen Lacey reports over on GreentechEfficiency, researchers at CO2 Scoreboard have come to rather a different conclusion. They found that, on a nationwide level, more than 50 million megawatt-hours of coal simply dropped … Read More

We previously reported on Tesla’s aim to pay back its Department of Energy (DOE) loan 5 years early. The company has made some strong steps in that direction this week with a couple of major fundraising announcements. As part of that, Elon Musk himself is investing a good chunk more money ($100 million) into the company. Naturally, these positive announcements (on top of all the others Tesla has been making in recent weeks) have helped … Read More

With Dr. Ernest Moniz officially confirmed at the next US Secretary of Energy, leading cleantech and green groups are getting their statements out regarding what they think of this. Here are a few I thought were worth publishing, followed by some of my own thoughts: EDF President Fred Krupp: Today's unanimous Senate vote to confirm Ernest Moniz as our next Secretary of Energy is great news for America. It shows that when Congress puts politics aside, … Read More

By Chris Robertson Large-scale solar power plants are now economic in Oregon. This is one of the surprising findings of the Oregon Solar Energy Industries Association's recently published "Vision to Integrate Solar in Oregon" (VISOR). Produced by Chris Robertson & Associates, LLC, with support from the Bonneville Environmental Foundation, the VISOR study can be accessed at chrisrobertsonassociates.com The cost of producing solar electricity from large-scale power plants is less than the regulated avoided costs of the two … Read More

Herman Trabish of Greentech Media has happened across a pretty interesting find — 97% of new electricity generation capacity in line to be added to the California grid in the second half (2H) of 2012 is from solar power projects. This is according to the California Independent System Operator (the ISO), as published in the 2012 Annual Report on Market Issues and Performance. In total, 1,633 megawatts of generation capacity are in line to be added to the grid in … Read More
