Zachary Shahan just put together statistics on the amount of solar installed by state on a per capita basis through 2012.
The results are interesting (and the full post can be found here) but none of these results are more interesting than the curious case of Arizona.
Arizona has historically been a large coal producing and consuming state and despite recent growth in solar has not been a leader on renewable energy policy or deployment.
The following guest essay was written by Paul Symanski. Paul is an electrical engineer with expertise in solar energy, and shares his views on why solar power often faces unnecessary headwinds. —————- To anyone who has ever spent a day in Arizona’s Valley of the Sun, it is obvious. The sunniest state in the nation is blessed, cursed, with a fierce sun. Yet, as one explores the landscape, artifacts of the capture of solar energy are conspicuously absent. This dearth is true for solar electric, domestic hot water, passive solar design, and even for urban design. It is as if the metropolis stands in obstinate defiance against the surrounding desert and its greatest gift. Yet, the incessant sun is a… Continue»
I am going to be offline for a few more days, enjoying some time with the family. In the interim, Tom Standing has sent some detailed replies to some of the comments following his posts Arizona Solar Power Project and Ambitious Solar Plans in France. —————————— Here is some additional material in response to a few of the comments that were submitted regarding my essays on the solar project in Arizona and the solar plan for France. First is a general comment about my intent with the two essays. I am merely attempting to contribute some hard-edged reality to many solar proposals that do not seem to have been adequately appraised through the conceptual engineering process. The value and scale… Continue»
The following guest post was written by Tom Standing, a “semi-retired, part-time civil engineer for the City of San Francisco.” In Part 1, Tom takes on the calculations for a 280 MW solar thermal plant in Arizona that I looked at back in February. My conclusion from that essay was that the electrical demands of the U.S. could in theory be met on 10,000 square miles of land. Tom peels the onion a few more layers and puts the energy production into perspective. While solar calculations are by no means second nature to me, I see no obvious errors in Tom’s calculations. But I consider peer review to be a very useful component of my blog, and I know that… Continue»
I couldn’t make this stuff up if I tried. The following was called to my attention in an e-mail earlier today after Ron Steenblik uncovered the story: Yuma doctor hopping on board booming ethanol trend Continuing the trend that I reported on previously, amateurs continue to jump onto the ethanol bandwagon: Dr. Sultan Lalani doesn’t lose sleep over the biggest project he has ever done. And he said he doesn’t lose any sleep over criticism of the proposed 55-million-gallon per year ethanol plant he hopes to build near Tacna either. With a construction cost of $125 million, this plant is serious business, but Lalani said it doesn’t overwhelm him. He wants to do the project, located at Avenue 47-1/2E and… Continue»
