The Week In Cleantech, July 9 to July 15

Last week, Paul Davidson at USA Today told us about how Sodium-sulfur (NaS) batteries can increase the reliability and efficiency of the grid. On Monday, Keith Johnson of The Wall Street Journal told us that Wind Turbine Makers can't keep up with demand.   Investment tip: this should be good for 2nd and 3rd-teir turbine makers who otherwise would not be able to sell their products.  I've noticed this in a flurry of turbine sales by Composite Technology Corp.  (CPTC.ob), a company I own not for their turbine business, but instead because I see great potential for their transmission...

The Week In Cleantech (Aug. 24 to Aug. 30) – And The Tax Credit...

On Sunday, Technology Review showed us the first tidal power generator. Harnessing the ocean's power is the next frontier in utility-scale alternative power generation, but this has so far proven difficult given all that the sea can throw at what humans try to put in it. This installation produces power at a hefty 0.30 to 0.40/kWh, but scale can bring this down to 0.20/kWh. Cut that in half again and now you're talking. On Monday, Clean Edge told us that Schott was planning a partial spin-off of its PV unit through an IPO. Given the headwinds the Eurozone...

The Week in Cleantech (Jan. 20 to Jan. 26) – Renewable Energy Is Coming...

On Tuesday, Todd Woody at Green Wombat told us the the clock was ticking on the crucial solar investment tax credit. When the solar ITC was dropped, the potential impacts were unclear although many folks had a good idea of what might happen. It now seems as though this is indeed throwing a spoke in the wheel of more solar development in the US, although industry leaders apparently remain sanguine. Given the amount of debt financing solar developments typically get, throw on top of ITC concerns high levels of uncertainty in capital markets over the direction of the...

Trade Wars and Patent Wars and EVs- The Week In Cleantech: June 1, 2012

Tom Konrad CFA May 29: Chinese City of Hangzou Planning Electric Leasing Program to Include EVs This article in Zhejiang Online does not mention Kandi Technologies (KNDI) by name, but it does say the city of Hangzhou is planning on adding electric cars to its electric vehicle rental system, and the price will be the same as electric bike rentals.  To keep the price and space usage down, Kandi Technologies mini-EVs and Smart Vertical Parking System (described here) seem ideal.

The 10 Most Blogged Cleantech Stories of 2007

What were Cleantech bloggers blogging about in 2007?  We don't have to wonder... instead, I asked Brian, AltEnergyStocks.com's web guru, to do a special run of our Cleantech News Algorithm. The Cleantech News Algorithm automatically by scans nearly 300 cleantech blogs and news sources, selected for their cleantech content. It takes three main criteria into account: 1) what other bloggers are saying about a news item, 2) how users across the Internet prefer a news item (which we call 'social popularity'), and when the item was written.  Normally it gives high priority to fresh news items, but this...

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...

2008: The Year of (Un)Sustainable Biofuel

Last year, I used a special run of AltEnergyStocks.com's new Cleantech News (CTN) aggregator to bring you the ten stories of 2007 which bloggers found most interesting or controversial. Continuing the tradition, below are the ten stories of 2008 which Cleantech and Green Bloggers were talking about.

The Week In Cleantech (Apr. 20 – Apr. 26) – Are Alt Energy Stocks...

On Monday, Michael Kanellos at CNET's Green Tech Blog told us that cellulosic ethanol was to surpass corn...in 14 years. Turns out he got that info from one of the leaders in making enzymes to break down cellulose. So if it takes about 14 years for cellulosic ethanol to scale up production levels to about 15 billion gallons annually, or roughly 10% of current liquid fuel consumption in the US, could there be a risk that cellulosic misses the boat altogether? Most of the estimates thrown out there for the cost of cellulosic to be competitive with corn are...
