Algae is the most promising source to produce oil in the quantities needed to displace any significant amount of petroleum. Can is Petrosun (Pink Sheets: PSUD) the company to fulfill this promise? I doubt it; follow the link to find out why.

We’re way behind the curve on climate change. Only after we have a new President is the US likely to take action to limit greenhouse gasses. Meanwhile the artic ice sheet is vanishing faster than any of our models predicted, and the world is emitting more carbon than even the most pessimistic IPCC projections.
Given that backdrop, it’s too late to wait for some new technology to come along and save us, be it cellulosic ethanol or carbon capture and storage. Investors should keep that in mind, too.
When the world wakes up to the urgency of Climate Change, more money will be spent on near term solutions than research into new technology.
The scale of the problem is daunting, which is why I believe there is such a temptation to invest our hopes in new technology, as opposed to investing our dollars in the technology we have today, which can take us most of the way we want to go, if only we can muster the political capital (the cost is negligible, because the efficient use of energy almost always than pays for itself and then some.)
That’s why I’m calling for a Clean Energy Marshall Plan.

I Just completed a series on Ten Renewable and Energy
Efficiency companies to buy when the market hits bottom. These are solid
companies, and a market downturn is a great time to aquire any and all of them.
I also mentioned a few more which almost made it into the
list in the introduction and also here.
Note: I and/or my clients have positions in all the stocks mentioned.

I took my 2002 Prius in to the shop today to have the brakes looked at because they were squeaking when I back up. It has 78,000 miles on it, and I’ve never changed the brake pads: most of the braking is done by the electric motor during regenerate breaking , but after 78K miles, the squeaking made me think they’d finally been worn down enough to be replaced. The reason I only heard squeaking when I back up is because the electric motor does the breaking almost all the time (unless I’m stomping on it) under normal
driving conditions.
Wrong! The garage just called me and told me it by back pads were about 1/2 worn down, and the fronts looked like they’d been recently replaced, but not resurfaced. The surface was glazed, which is what was causing the squeaking. Or maybe it was the rear pads.
At this rate, it looks like I’m <em>never</em> going to have to replace the brake pads on the front, while I might have to replace the rears once before I hit 200,000 miles.
I’ll have them checked again in another 5 years, just to be safe.

RealClimate has an article outing "The 2008 International Conference on Climate Change" as a publicity event to generate reports in the press of a lack of consensus in the scientific community about anthropogenic Climate Change.
I was struck by this quote:
they are offering $1,000 to those willing to give a talk. This reminds us of the American Enterprise Institute last year offering
a honorarium of $10,000 for articles by scientists disputing anthropogenic climate change. So this appear to be the current market prices for calling global warming into question: $1000 for a lecture and $10,000 for a written paper.
That’s a high price, since serious scientists usually happy to deliver lectures on their scientific work for free. I can only conclude that we have passed "Peak Climate Denial" and that, because demand for "scientific" papers continues to be funded by industry lobbies such as the Heartland Institute and the American Enterprise Institute, the price has had to rise in the face of diminishing supply (i.e. scientists willing to destroy their reputations for money.)
Unfortunately, accurate data on the Climate Denial Reserves and Prices are scarce, but these prices make me think we’re well past peak (or at least on an undulating plateau.) Fortunately, society will continue to function (and most likely run better) when Denial Depletion reduces Denial Reserves to a few crazy bloggers in dark corners of the Internet.

A trip down to the local national party offices to participate in a press conference asking the presidential candidates to pledge their support for clean energy legislation got me thinking about the candidates… I wasn’t sure which candidate has the best clean energy platfom. So I spent a day reading thorough thier platforms, and came to a surprising (to me answer).

I had just written an articles for the Colorado Renewable Energy Society’s e-newsletter CRES Clips about goings on at the Colorado Public Utilites Comission (PUC), when a piece of big piece of PUC related news came out:
Governor Ritter appointed the current Executive Director of Environment Colorado to fill a recently vacated seat on the PUC.
Why should every advocate in Colorado care? Because it’s great to have another sympathetic ear!
What follows is the article I wrote for CRES Clips, to give readers unfamiliar with the PUC an idea of why I think this is so important:
The Colorado Public Utilities Commission: Where Energy Policy is Implemented
2007 was a banner year for the
Colorado
lawmakers when it comes to energy policy, and with all the successes. While it would be tempting for clean energy advocates to declare victory and go home, getting good laws passed is only the beginning. When it comes to implementing laws that pertain to investor-owned utilities, the responsibility falls on the Colorado Public Utilities Commission (PUC) to interpret the legislation and ensure that our state’s public utilities comply with that interpretation. Here, “public utilities” means Xcel and Aquila , since rural electric cooperatives and municipal utilities are generally exempt from PUC regulation.
The PUC accomplishes its business in a series of “dockets” in which various “interveners” submit testimony (and respond to other interveners’ testimony) for the PUC to consider. Individuals can become interveners, but it is time consuming and requires
knowledge of PUC procedure. Public interest groups with an attorney can also intervene, with various expert witnesses submitting testimony on behalf of that group.
CRES is not currently intervening in any dockets, although several members of the Policy Committee (including myself) are involved in one way or another. Given those inherent conflicts of interest, CRES is not currently endorsing any particular intervening group.
What follows is a quick summary of some of the most important dockets before the PUC this year, and the groups who support Renewable Energy and Energy Efficiency who are intervening, and whom you can support or contact for more information about their activities. Also, it is possible that the PUC will combine some of these dockets.
07A-447E Xcel Resource Plan. These dockets will determine the mix of new generation and energy efficiency resources with which Xcel plans to meet our anticipated electricity needs in the coming years. Anticipated/ current interveners: EEBC, IEA, RUC, SWEEP, WRA.
07A-420E—Xcel
DSM Plan in which the PUC will review Xcel’s proposals for electricity DSM policy including energy savings and DSM budget goals, DSM program cost recovery, and incentive to the utility for implementing effective DSM programs. This docket was initiated in response to DSM legislation enacted last year, HB 07-1037.
07A-462E—Xcel
Renewable Energy Plan in which the PUC will review Xcel’s plans for complying with the recently doubled Renewable Energy Standard. Interveners: CoSEIA, WRA.
07M-446E—Xcel
Plan on Transmission. Transmission is essential to bringing the power from renewable energy sources to population centers. This docket will determine much of when and where transmission is upgraded or built, and so will have a long term impact on what Renewables can be developed. Current Interveners: IEA, WRA.
07R-371G—Gas
DSM Rules. This docket will determine the key policies governing gas utility energy efficiency programs, including energy savings goals and how utilities will be compensated and rewarded for reductions in natural gas usage. Current Interveners: EEBC, RUC, SWEEP.

· Filed under Technology, solar thermal
The December 6 Technology Quarterly from The
Economist magazine profiles
a Dutch office building which is both heated and cooled using heat (or cold) from the asphalt of the road outside the building, as opposed to the more conventional use of solar thermal panels on the building’s roof. The article optimistically ends,
The result is cheap heating in winter and cheap cooling in summer. And there is a bonus. Summer heating softens asphalt, making it easier for heavy traffic to damage the road surface. Dr de Bondt’s system not only saves electricity, but also saves the road. Expect to see more examples of it, in other countries, soon.
While this is a very elegant solution, the author fails to grasp that,
because the road is essentially an unglazed thermal
collector, and only gets
warm in the summer or cool in the winter, requiring that seasonal heat be stored. Summer heat from the asphalt is used to heat the building in winter, while the chill of the inter road cools the building in summer.
In this particular case, seasonal storage is accomplished with heat exchangers placed in not one, but two separate natural aquifers near the building. The fortunate proximity of two such aquifers is extremely rare. While this is a very elegant way to heat and cool a building, the lack natural aquifers in which to store seasonal heat will likely prevent widespread adoption of this
technology, no matter what the author believes.

Does it seem totally unfair to you that the young, who are typically much more environmentally aware, are often stuck living in cold, drafty, unhealthy, and expensive to operate rentals, while it’s the old and the wealthy splash out on gigantic mansions with multiple low efficiency furnaces and air conditioners?
It does to me. Well, if you’re one of those green renters, you can do something about it. I’ve put together a checklist to use that can help you sift out the efficient buildings from all the cold, drafty ones.
Since it’s not really about stocks, I sent it over to Jetson Green as a guest post. But if it’s stocks that might benefit from the trend in energy efficient homes you’re looking for, I list several in the intro I wrote for it at Alternative Energy Stocks.

I was low on biodiesel for my Jeep while down in Denver ex-urb Parker last month, and know I wouldn’t find biodiesel there… so I only got a few gallons. But I was surprised to see this sign:

E85, but no biodiesel. That’s Parker for you. And I was just talking about an ethanol glut!
