Energy Efficiency

I recently attended the Optoelectronic Industry Development Association's (OIDA) "Green" Photonics Forum.  Unlike dirty industries trying to appear green, the Optoelectronics industry does not really have to try to be green.  Two prominent examples familiar to clean energy investors are Concentrating Photovoltaic Solar (CPV) (i.e. using optics to focus light on high efficiency solar cells) and Light Emitting Diodes (LEDs). The presentations on Tuesday focused on the above technologies, and I was struck by a common problem faced by both: heat dissipation.  According to Sarah Kurtz, a National Renewable Energy Laboratory scientist leading the team working on high-efficiency, multi-junction...

Lighting Science Group Corp. (LSGP.OB) unveiled an LED R30 floodlight which provides the equivalent light output of a 65 watt incandescent floodlight but uses up to 80% less energy over a lifetime that is up to 50 times longer. The new floodlight, powered by Optimized Digital Lighting(TM) (ODL(TM)) technology, is designed for use both indoors and outdoors, in recessed cans and other applications that require a standard screw base socket. The R30 floodlight is one of the most widely used bulbs today, typically found in large quantities in commercial, industrial, retail, educational and hospitality facilities.

by Debra Fiakas CFA On Friday Rubicon Technology, Inc. (RBCN:  Nasdaq) announced the appointment of a new chief operating officer to manage the company’s sapphire materials production.  Rubicon is a producer of materials used in electronics components, including the company’s specialty, monocrystalline sapphire materials.   Rubicon chose a seasoned operator for the COO post, which now encompasses functions previously carried about by managers in two different positions.  The new hire, Hany Tamim, was previously with SunEdison (SUNE:  Nasdaq), the developer and producer of solar cells and modules.  He has experience in managing crystal growth and...

This article has been cross-posted on The Oil Drum. Last month, I brought you some nice maps showing when and where good wind resources are found in the US.  Now I've found something better: a visual comparison of electrical load with wind farm production, published by the Western Area Power Administration in 2006.  The study compared electricity production from five wind farms in Northern Colorado, Southwestern Nebraska, and Central Wyoming in 2004, 2005, and the start of 2006, compared with electricity consumption in the same area over the same time period. Comparison of Wind Production to...

Tom Konrad, CFA With new climate legislation or a renewable portfolio standard unlikely now that Republicans control the US House of Representatives, progress on clean energy is likely to come mostly from action at the state level, and from regulation at agencies such as the EPA, rather than national legislation.  Why Energy Efficiency Standards Make Economic Sense One type of regulation that is fairly uncontroversial is improving energy efficiency standards, that is regulation of the amount of energy an appliance or other device can consume during normal use.  In an efficient market, regulation might bring...

I highlighted FLIR Systems (NASD:FLIR) as a way to participate in the growth of the energy auditing industry in late 2007.  I was ambivalent about it at the time: I very much liked the potential growth story, but felt the stock was overvalued. Flir has fallen about 35% since late 2007, and 50% since its peak in July 2008 (while revenues have grown about 50%), prompting me to give it another look.     Infrared Stimulus Weatherization of low income housing and Federal building retrofits are a major component of the American Recovery and Reinvestment Act (aka "Stimulus Package.") ...

Tom Konrad CFA With earnings announcements coming fast and thick over the last two weeks, it has been all I can do to keep up, let alone go into detail about the companies I usually follow, as I did with Maxwell Technologies (NASD:MXWL) earlier this week. (Note: I am currently long Ameresco and Short Maxwell.) Rather than remain completely silent, I’m going to attempt to focus on the main take-aways I’ve gleaned from the filings and earnings calls, starting with Ameresco’s (NASD:AMRC) potentially confusing earnings. Another “Miss” Ameresco again missed First Call analysts’ average earnings estimates for the...
