How Infrared Imaging can Sell Energy Efficiency
Energy Efficiency breaks the laws of economics. Despite the fact that it's considerably cheaper then traditional energy sources, as well as providing substantial benefits in terms of comfort, economic growth, safety, and the environment, barriers arising from misplaced incentives and the attitudes, awareness, perceptions, and general level of knowledge all conspire to prevent people from taking steps which would otherwise be extremely rewarding. The key to better implementation of Energy Efficiency programs are programs to raise people's interest or awareness. For instance, there is the example of how Woodstock Hydro found that their customers' electricity usage dropped 15%...
Clean Energy Stocks Shopping List: Five Energy Efficiency Stocks
Stocks may be expensive now, but they won't be forever. Five energy efficiency plays to buy when they're cheap again in efficient HVAC, desalination, thermal imaging, and lighting. Tom Konrad, Ph.D., CFA This article continues my Clean Energy Stocks Shopping List series. In the first, I looked at five clean transport stocks I'll be looking to buy when the market falls. In the second, I took a step back, and outlined why it makes sense to wait for better prices than to buy these companies now. Here are five stocks I'll be looking to buy in my all time...
NovX21: Urban Miner
by Debra Fiakas CFA There's Platinum in them catalytic converters. Mention platinum and most of us think about beautiful and expensive jewelry. However, platinum can be found in the dullest of products. Catalytic converters used in automobiles for emissions control represent about one-third of the demand for platinum. The devices attached to the rear of our cars uses a mix of previous metals to remove nitrogen oxides, carbon monoxide and hydrocarbons from engine exhaust. The catalytic converter on a typical car uses a gram or less of platinum,...
Power Integrations: Profiting from Efficient Electronics
Tom Konrad, CFA With new climate legislation or a renewable portfolio standard unlikely now that Republicans control the US House of Representatives, progress on clean energy is likely to come mostly from action at the state level, and from regulation at agencies such as the EPA, rather than national legislation. Why Energy Efficiency Standards Make Economic Sense One type of regulation that is fairly uncontroversial is improving energy efficiency standards, that is regulation of the amount of energy an appliance or other device can consume during normal use. In an efficient market, regulation might bring...
The Alternative Energy Fallacy
John Petersen In 2009, the world produced some 13.2 billion metric tons of hydrocarbons, or about 4,200 pounds for every man, woman and child on the planet. Burning those hydrocarbons poured roughly 31.3 billion metric tons of CO2 into our atmosphere. The basic premise of alternative energy is that widespread deployments of wind turbines, solar panels and electric vehicles will slash hydrocarbon consumption, reduce CO2 emissions and give us a cleaner, greener and healthier planet. That premise, however, is fatally flawed because our planet cannot produce enough non-ferrous industrial metals to make a meaningful difference and the prices...
Bargain Priced Alternative Energy Stocks
A review of Crystal Equity Research’s novel alternative energy indices found a number of companies that have delivered exceptional price appreciation over the last year. Several were reviewed in the recent post “Alternative Returns” on May 8th. Expectations for growth appeared to be driving the price movement, so the last post “Quest for Growth” featured four companies from the indices for which analysts have posted high growth predictions. Not unexpectedly some investors have already bid higher the stocks of those promising companies.
In this post we go back to the lists to find the companies with both high growth predictions and low price-earnings...
Orion Energy Systems: Right Industry, Right Time
by Debra Fiakas CFA March 31st marked the end of fiscal year 2014 for Orion Energy Systems (OESX: Nasdaq), a provider of energy-saving lighting systems. The half dozen or so analysts who follow the company on a regular basis think the company will be able to report about the same level of sales as the same quarter last year, but will actually suffer a penny loss instead of making a profit as they did last year. If they are right it will be a setback for Orion, which higher sales this year than last and has so far...
A Clean Energy REIT: Hannon Armstrong Sustainable Infrastructure
Tom Konrad CFA On April 18th, Hannon Armstrong Sustainable Infrastructure Capital (NYSE:HASI) IPOed on the New York Stock Exchange. HASI is one of only two publicly traded Real Estate Investment Trusts (REITs) dedicated to sustainable infrastructure. The other such sustainable REIT is Power REIT (NYSE:PW), which I have written about extensively. PW is both illiquid and involved in significant litigation, two factors which may put off the conservative investors who gravitate towards REITs. In December, Power REIT purchased the land...
Waterfurnace 7 Series vs. Climatemaster Trilogy Geothermal Heat Pumps: The Best of the Best
UPDATE: I just looked into the 7 Series vs the Trilogy 40 in more detail here and came to a slightly different conclusion. Tom Konrad CFA Geothermal heat pump diagram via Bigstock Waterfurnace Renewable Energy (TSX:WFI, OTC:WFIFF) launched its new highly efficient 7 Series geothermal heat pumps (GHP) today. The 7 Series commercial release beats Climatemaster’s (a division of LSB Industries (NYSE:LXU)) Trilogy 40 as the first commercially available GHP with a variable speed compressor.

Looking forward, 50 percent of those polled...
Cleantech is a Bunch of Hot Air!
David Gold While renewable energy often captures most of the cleantech headlines, if anyone doubts why energy efficiency must play a significant part in the cleantech effort – as significant, if not more so, than the role of renewable energy just examine the energy flow graphic developed by McCall and Bassett and reprinted in the June edition of Technology Review. At least half of U.S. energy consumption goes to nothing more than creation of hot air through waste heat. And, when one realizes that much of the 13.9% of electricity output from power plants shown in the...
Who’s a Fat Cat?
Tom Konrad CFA A Fat Cat. Photo of "Cauchy" by author. Friday, in a generally positive article about Lime Energy (NASD:LIME), I noted that the top five executives at the company seemed overpaid in comparison to one of their nearest rivals, Orion Energy Systems (NYSE:OESX). Since this was not based on in-depth research, and is a pretty serious allegation about a company I’m otherwise enthusiastic about, I decided to do some more digging. Who is a Fat Cat? Using data on executive pay from Morningstar, I compared executive pay at...
Lime Energy Gets $2.5M to Fund Growth of Utility Business
Tom Konrad CFA I was surprised when Lime Energy (NASD:LIME) announced that it was selling a million shares to Richard Kiphart, one of its own directors and its largest shareholder. Last year, CEO John O’Rourke had told me that Lime expected to reach profitability without having to raise additional capital. What happened in the meantime? It was the best of Limes, It was the worst of Limes Two things had happened, one bad, one good. The bad was that Lime’s C&I business turned in a particularly weak first quarter, cutting expected profits by a little over $1...
Why the Financial Crisis is like Energy Inefficiency
Tom Konrad, Ph.D. I have a regular column called Greener Money in Smart Energy Living Magazine. The Spring issue just printed, and I'd like to highlight this column, because it discusses ideas I have not written about elsewhere. The column begins: As people become more aware of how we use energy, many become amazed and appalled at the sheer waste of it. Why are homes built without attention to insulation and sealing that would not only make them more comfortable, but also mean they cost less to live in, even with the slightly larger mortgage payments? Why do...
Hidden Gems? Why Green Investors Should Look at PFB, Vodafone And Telefonica
Part 1 of 2 Bill Paul Looking for alternative energy stocks with undiscovered potential? Who isn't? Here are three possibilities (with three more to come next week). You can decide for yourself whether they are worth further investigation. First up: PFB Corporation, which trades on the Toronto Stock Exchange under the symbol PFB. Calgary-based PFB is an energy efficiency play. The company makes insulating building products that it sells under branded names in commercial and residential markets in North America and Japan. The company most recently reported third quarter net income of $1.6 million or 24 cents vs. $1.1...
