The Next Trend: Integrating PV with Solar Thermal
Tom Konrad CFA The Once Bright Future of CSP Solúcar PS10 solar tower. Photo by afloresm via Flickr Since before I started writing about investing in clean energy in 2006, I’ve been fascinated by Concentrating Solar Thermal Power (CSP.) CSP held the promise of much cheaper energy than was then available from photovoltiac (PV) solar, combined with thermal storage, which eliminated the variability problems of PV. Unlike other renewable energy able to produce baseload power (geothermal, biomass, and hydro), CSP is scaleable: The solar resource in areas...
Energy Independence Day
Jim Lane Independence Day Celebration photo via BigStock Yesterday, in the United States the bands and bunting were on display, because it was Independence Day. But is freedom really sustainable, without energy independence too? It would be a sweeter thing, political independence, if it were accompanied by more energy independence. For examples, choices at the pump that didn’t involve wealth transfers to people who oppose the principle of ballot boxes. But before there is energy independence, there has to be more freedom from the entropy that...
When Will Polypore Payoff?
by Debra Fiakas CFA Diagram of a battery with a polymer separator. Lithium ion batteries make it possible to recharge your smart phone, camera and a multitude of other have-to-have-with-us-every-moment devices. Yet the average person knows very little of the inner workings of something so important to our daily lives. One little item in a battery is a highly specialized membrane that fits neatly between opposing electrodes - the positive and negative poles that make an electrical charge. This membrane manages the charge and discharge process. ...
SunShot Grand Challenge: The SunShot Swerve
Ed Gunther Has a permanent swerve or shift downward of the PV (Photovoltaic) Learning Curve been caused by PV industry overcapacity, normalized polysilicon prices, and the aggressive SunShot goals? From SunShot Grand Challenge: The SunShot Swerve On the second day of the SunShot Grand Challenge Summit and Technology Forum, SunPower Corporation (NASDAQ:SPWR) President Emeritus Dr. Richard Swanson presented “The SunShot Swerve” providing his perspectives on where the PV industry is today and how SunShot has influenced the industry’s direction. After explaining the book that motivated the title, Dr....
Is Ocean Energy More Than “A Very Expensive Hobby”?

Referring to three levels of development Epoch 1, 2, and 3 Andrew Tyler, CEO of Marine Current Turbines (MCT), a company now owned by Siemens (SI), gave a few key pointers to companies interested getting beyond the “very expensive hobby” stage of ocean energy development. While his tongue-in-cheek...
Two EVs for the Other 99%
Tom Konrad CFA The Tesla Model S, from the unveiling on 26-Mar-2009. (Photo credit: Wikipedia) An EV for the 1% The chatter among electric vehicle (EV) enthusiasts and investors is all about the launch of the Tesla (NASD:TSLA) model S. A cool ride, no doubt, but not many of us are ever going to buy a sedan that starts at $49,900, even after the $7,500 tax subsidy. Fortunately for the rest of us, this week also brought news about two much more affordable EVs. An EV for the 99% Chicago...
