I asked my readers at Alternative Energy Stocks what companies they wanted to know more about, and the two most requested were a transmission and wind company (CPTC.OB), and a company looking to make oil for biodiesel from algae (PSUD.PK).

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 did two top Ten lists to bring in the New Year. First, I picked ten speculative plays in renewable energy and energy efficiency that I think will do well. This was a 3 part series:
Part I: LED Stocks and Ultracapacitor stocks
Part II: Batteries, Distributed Generation, combined Heat and Power, and Electricity Transmission
Part III: Geothermal, Wind and Wave Power stocks, and a Solar Short
My second Top 10 list is plain fun… we used an algorithm to see what stories cleantech bloggers were linking to in 2007, and I did a short summary of each. Here is my Ten Most Blogged Cleantech Stories of 2007
Enjoy!

For the Shopping season, I’ve just publised an article on a gift that’s greener than just giving more “stuff.” Help your young ones prepare for their future (and the future of the planet) with my Top Five Stocks to Give as Gifts this Holiday Season.

I’m bullish about the battery industry, because I fee that rising oil prices and consumer awareness will lead to accellerating adoption of hybrids, plug-in hybrids, and electric vehicles over the next decade. So I’ve been researching the battery industry, and trying to look for companies that can benefit without being tied to a single battery chemistry, since I doubt the conventional wisdom that some company will perfect the Lithium-Ion battery, and that will be the solution for all mobile energy storage.
I just did a write up on one company that I think not only has technology that is applicable to a wide variety of chemistries, but it’s also selling for less than what I think its assets are worth.
The company is Electro Energy Inc. (EEEI), and you can read more by clicking here.

Mea Culpa, I’ve been falling behind keeping this blog updated… but most of you probably realize that the real stuff goes on at AltEnergyStocks these days. Over the last two weeks, I wrote a series of companion pieces to a series of articles that were published on energy Tech Stocks, based on a long interview Bill Paul, the writer did with me. Here’s an index to them (and they each contain links to the interview articles.)
1. Large Scale Electricy Storage
2. Plug-In Hybrids and Battery Stocks
3. & 4. Improving Transmission and my Ambivalent stance on Biofuels
5. Light Emitting Diode (LED) Stocks
6.Cellulosic Ethanol and Sustainable Forestry.
7. Alcoa and Blue Chip Stock Picks

I have now posted the last two articles in my series on the WGA Energy Efficient Buildings Workshop.
The third article (here) talks about some of the “above code” standards, such as Energy Star and Built Green, why I feel the code should resemble these standards a lot more than it does now (above code should mean measures that are not viable on a pure economic basis, but that people want because it makes them feel good… when total cost of ownership is taken into account, these “above code” standards actually produce homes that are cheaper to live in and own than houses built just to code.)
I also talk about several companies that my benefit from a move to wide adoption of these above code standards, as well as from energy retrofits of existing homes.
Article number four (here), talks about the trend to performance contracting, where a building owner contracts for a certain level of service (lighting levels, temperature, etc.) with a third party, and that party upgrades the building’s efficiency, with the savings from efficiency gains not only paying the energy bills, but also paying for the upgrades (which can include solar panels and other renewable energy projects as well as energy efficiency upgrades) as well as a profit for the contractor.

Many energy advocates are concerned about the construction of new conventional electricity generation. This is not only due to the harmful effects of mining, using, and disposing of the waste from coal, natural gas, and uranium, but also because there is only so much electricity demand. My Alt Energy Stocks column this week exproles the possibility of utilites building too much conventional generation to need any renewables at all.
Utilities often say that they will have trouble meeting future demand… this was the justification for the coal plants (now mostly replaced by nuclear) planned by TXU. But these projections massively underestimate the potential of imporved energy efficiency which most studies put at about 1.2% acheivable savings per year, but I believe could be much higher with changes to the regulatory landscape.

It’s unfortunate, but even many environmental advocates also have money invested in companies that are doing a lot to make our world a lot less pleasant place to live. After all, we need to put our money somewhere, and a nonprofit salary isn’t going to fund your 401k to the point when you can retire after having saved the world if you’re money is in CDs.
However, renewable energy and more generally progressive companies that advocate for action on global warming are giving us more and more opportunities to profit from our principles. Here is a brief look at how the stocks of the members of the United States Climate Action Partnership are doing in comparison to Big Coal so far this year.
Coal is off to an early lead, but if you want reason to hope, I give a few at the end of the column. But the best reason for me is the ability to sleep at night.

My weekly column for AltEnergyStocks again doubles as part of my study for the second CFA(R) exam. The Equity valuation part of the curriculum contains a chapter by Michael Porter on analyzing competitive pressures in an industry. I decided to apply it to the corn based Ethanol industry, and, as often is the case, it changed my way of thinking about the industry. I’ve never been bullish, because I worry about a classic commodity squeeze: both ethanol and the main feedstock (corn) are commodities, and are subject to forces outside the industry which effect their prices. For instance, if corn harvests were to be poor because of drought or pests, at the same time that oil prices fell, many ethanol producers would be forced out of business because their costs exceed their selling prices.
I also went on a little rant about the typical measures of Energy Payback and Energy Return on Energy Investment (ERoEI) often used in the industry. These measures are often used to criticize ethanol, but it is a weak criticism, because they do not take into account the time value of energy: namely that a kWh of electricity today is a lot more useful than a kWh produced 30 years from now. We should instead be thinking in terms not only of how much energy we have to use to get energy out, but also in terms of how soon we get that energy.
I propose a couple measures, of Energy Net Present Value (ENPV) and Energy Internal Rate of Return (EIRR) which I think would give us a clearer view of the undying energy economics (and hence the potential economic profitability) of various energy production technologies. But that is a column for another week.
This week, here are my thoughts on competition in the corn Ethanol industry, and how it might affect your investments.
If you have a subscription, there’s also an excellent article in the NYTimes on ethanol in Hawaii. I think it ties in well to this one, and the one I wrote last July about renewable energy in Maui.
