The Week in Cleantech

On Sunday, Tom Philpott at Peak Energy told us about The End of Food. The book, that is. While food is neither alt energy not cleantech, it is a key environmental theme in my view and will grow in importance as the effects of climate change are felt across the globe. On Monday, David McClellan at Solve Climate argued that the costs of nuclear energy were rising out of reach. A good attempt at coming up with a comparison of wind and nuclear prices, and interesting in the context of my earlier article on power plant costs. ...

Jeff Siegel March 26: Tesla Motors (NASDAQ:TSLA) Upgraded to $49 A123 Systems (NASDAQ:AONE) announced today that it will have to replace battery modules and packs that may contain defective cells. The replacement is likely to cost about $55 million. The stock is down about 4 percent in pre-market. If the broader market stays positive today, the damage could be contained. I expect to see a number of follow-up articles blasting A123 because, well, the company works in the electric vehicle space and it's received government support. The combination of the two makes it a popular target....

Jeff Siegel and Tom Konrad April 30: Orion Energy Systems (OESX) Triples Stock Buyback TK: Sometimes microcap stocks fall just because no one is paying attention.  The directors of Orion Energy Systems (AMEX:OESX) clearly think their company is one such. Orion is an energy management company with a focus on high efficiency lighting systems and alternative energy system integration in commercial buildings.  The company is profitable, with a trailing Price/Earnings ratio of 18, a Price/Sales ratio of 0.5, and sold at less than half of book value ($4.05) when the market closed on Friday...

On Sunday, Edgar A. Gunther at Gunther Portfolio provided some silicon updates from Intesolar North America 2008. Solar investors never get enough silicon updates, so here's another one! On Monday, Stacy Feldman at Solve Climate told us that China was now making increasingly more wind power parts. Actually, she is reporting on an article that was written last week and that I missed because I took a break from the Week In Cleantech last weekend. With regards to Chinese companies active in wind, we already list some in our Cleantech Stocks section, and will be sure to keep...

On Sunday, Marc Gunther told us all about the greening of Goldman Sachs. As our regular readers know, Wall Street's involvement in environmental finance is one of our preferred topic of discussion. On Monday, Dana Childs at Inside Greentech told us that there might be some good...

The Economist is currently running an interesting poll on whether we can solve our energy problems with existing technologies or whether we will need breakthrough innovations. Add your vote! On Sunday, Domenick Yoney at AutoBlog Green told us that electric bike sales were soaring world-wide. I'm not sure what's a good play on this, but an interesting trend to note nonetheless. On Monday, Matthew McDermott at TreeHugger told us about another biofuel feedstock we may not have considered. Earlier this summer, David Pauly at Bloomberg was telling us about yet another such potential feedstock, which apparently is...

In Solar, John Gilluly at The Chip Stock Trader let us know that help was on the way for solar stocks. An interesting take on the solar installation business with a stock pick - Akeena Solar (AKNS). But Keith Johnson at the WSJ's Environmental Capital suggested everyone should put away the champagne: the much awaited bill extending tax credits for solar and wind, it seems, may not be passed this session. Failure to agree on a bailout plan over the weekend would just about fully re-load the gun for solar shorts to get back to work next...

In Solar, Eric Savitz at Barron's Tech Trader Daily wondered whether stock loan deals would be repaid. It's always important for shareholders to pay attention to which financing structures companies chose. In this case, if you understood this well, it could have a been good lateral short play on Lehman's problems. However, if you were long ESLR and had not paid this financing too much attention, you were probably not pleasantly surprised. Good CleanTech let us know about a new report claiming that thin-film will make up a whooping 40% of the solar PV market by 2012....

If you know of a good piece that you think should be included here, don't hesitate to let us know! This week, we particularly liked... On Monday, David Roberts at Gristmill gave us Vinod Khosla's forecast for 2007 (thanks to Tyler at Clean Break for this one). On Monday, Jack Uldrich at The Motley Fool noted how the solar industry is getting its lobbying act together and going to Washington. Stocks...

Tom Konrad CFA May 7: Auction of Uni-Solar Fails to Draw a Qualified Bid As if there weren't enough bad signs for the solar industry these days, Energy Conversion Devices (OTC:ENERQ.PK) is cancelling the auction for United Solar Ovonic LLC (A.k.a. Uni-solar) as a going concern because of the failure to receive a qualified bid in the court-approved bankruptcy proceeding.  The companies have retained an auction services firm to prepare for the sale of Uni-solar's assets. May 8: Earnings Misses Hide Strong Revenue Trends at Ameresco (AMRC) and Pike Electric (PIKE) Ameresco (AMRC) and Pike Electric...

The Week in Cleantech is a weekly roundup of our favorite cleantech and alt energy blog posts and stories from across the web. If you know of a good piece that you think should be included here, don't hesitate to let us know! This week, we particularly liked... On Tuesday, Tyler Hamilton at Clean Break told us to stop obsessing about corn. On Tuesday, Anders Bylund at The Motley Fool discussed 3 stocks that missed the mark. Stock discussed: Evergreen Solar . On Thursday, Jennifer Openshaw at TheStreet.com informed us that it might be...

On Tuesday, Mark Gongloff at the WSJ's Energy Roundup informed us that Alcoa couldn't wait to go geothermal. This is indeed an interesting development. Aluminum smelters are some of the most electricity-intensive industrial processes around, and, in a context of rising energy prices, there are very real incentives to explore alternatives for firms in this industry. On Wednesday, Kevin Bullis at Technology Review looked into making cheaper solar cells for us. Could Heliovolt be the next First Solar (NASDAQ:FSLR)? On Wednesday, Tyler Hamilton at Clean Break warned us of the inherent limitations of so-called "clean coal". The...

In Solar, New Energy Finance told us that Spain had raised the cap on new solar capacity, but not enough to appease critics. Ucilia Wang at Greentech Media brought us analysts' picks for 2009's winning Solar stocks, but they didn't mention Sharp (SHCAY.PK), which GoodCleanTech told us had developed a technique to halve silicon wafer costs. In Clean Transportation, Autoblog Green brought us Insight into Honda's new Global Hybrid.  And Autoboog Green also told us GM's Lutz was bragging about the Volt's "flawless" batteries, GoodCleanTech introduced Mazda's plans for a rival. Treehugger...

On Sunday, Sebastian Blanco at AutoBlog Green informed us that European biodiesel producers were intent on stopping the "US biofuel invasion". I have long argued that the drive to ramp up biofuel production in the US was more about placating the farming lobby than it was about global warming or weaning America off foreign oil. It follows, then, that just like agriculture, generous biofuel subsidies are going to lead to frictions in the international trading system. The same is true, by the way, for Europe. To be continued... On Monday, Eli Hoffman at Seeking Alpha reported that...

This week, we particularly liked... On Monday, Andrea Quong at Red Herring told us how China was about to take aim at global warming. This is latest move by the Chinese government only reinforces the perception already held by many industry observers that China is on its way to becoming a true global powerhouse for alternative energy. On Tuesday, Martin LaMonica at CNET Newsblog informed us that cleantech investing was surpassing telecom and medical devices. Another day, another report report pointing to exceptional and sustained growth in the cleantech sector. This is nothing to alleviate fears...
