Well I'm back after a little hiatus. Sorry I've been gone so long! I just took a new job at Go Green Solutions in Pasadena in mid-March. I've thrown myself headlong into the new position and as a result have let my blog posting responsibilities slide a bit. But not to worry, my new job dovetails well with what I've been talking about here in Energy Crunch (did the company's name give it away?) so I'll be able to continue to bring my insights to this column, as my throngs of readers will no doubt be assured to hear.
For today I just wanted to point out this article which gives further hope that soon solar power will be cheaper than fossil fuels, and the stampede to renewables will begin in earnest.
Enjoy the article, and check back now that I've got my schedule back under control a little bit.

Q-Cells and the Future of Solar Photovoltaics
The solar industry is booming. According to this article, "sometime in the next two years, more raw silicon will be going to solar panels than to electronics chips." And according to a report recently released by BCC, the market for solar PV cells will reach $32 B/year in 2013. Good news, but there's one catch: supplies of polysilicon, one of the key ingredients in many solar PV panels, are growing tight. The bottleneck isn't the raw material (sand), but rather the production capacity for refining sand into polysilicon.
This means two things: (1) a scramble among polysilicon PV cell manufacturers for supply, and (2) a move towards thin-film technologies, such as CIGS, which don't use silicon or use much less of it.
One company that's moved to address both of these issues is Q-Cells out of Germany. They've signed a long-term supply agreement with China's LDK Solar, locking in a supply of 43,000 tons of silicon wafers through 2018. And EverQ, their joint venture with Evergreen Solar and Norway's REC, has locked in supplies of up to 2,100 tons of polysilicon per year through 2015. That translates to enough silicon for an output of roughly 6,600 megawatt peak.
A quick back-of-the-envelope analysis shows that this translates to securing access to enough raw materials to convert into $16 billion of revenue, using the revenue per MW of PV cell in 2013 from the BCC report I mentioned above. So the polysilicon shortage shouldn't dent their growth:
Meanwhile, their subsidiary companies are ramping up thin-film technologies. Calyxo makes cadmium telluride PV cells and Brilliant 234 produces thin-film silicon modules. Solibro GmbH, a joint venture with Solibro AB, is a CIGS (cadmium indium gallium selenide) manufacturer.
This is an impressive company that seems to have all the bases covered. I'd keep an eye on them.
