Why Energy Efficiency is a Hard Sell
Two months ago, I was talking to an experienced entrepreneur who was exploring business models to provide geothermal heat pumps to households. At first blush, it seems like a great idea. Geothermal heat pumps often have payback periods of under five years, which translates into internal rates or return in excess of 20% over the 30 year life of the system. With plenty of room for a business to recoup its cost of capital and leave some money on the table for the consumer, it's amazing that there isn't a company in every jurisdiction already active in the market. ...
Lime Energy’s Long Dark Year Of The Soul
Tom Konrad The last year has been hard on Lime Energy (NASD:LIME Disclosure: I own this stock.) The company discovered problems with its internal reporting over a year ago, and the effort to restate the books and establish proper controls took much longer than anyone expected, in large part because the internal investigation uncovered additional problems as it proceeded. While the company was in danger of delisting, creditors were reluctant to provide funding, and this led the company to sell its two most capital intensive businesses: its asset development business, and its ESCO business. The ESCO business required backing...
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%...
FLIR: A Red-hot Energy Efficiency Stock
On Monday, I wrote that I wouldn't buy a house without an energy audit. For now, I'm in the minority, but I don't expect that to last. Each of these trends is likely to lead to more homes getting energy audits: Rising energy costs: as energy prices rise, knowing what to do to improve your home's energy efficiency will become more valuable. Weak real estate market. Now that the boom is past us, new home builders need to put more effort into providing and advertising a quality product in order to attract buyers and stay in business. ...
LEDs: A better light bulb. Again.
by Marc Gunther. So you remember CFLs, right? The curlicue bulbs? The time they took to go on? The harsh light? Despite their drawbacks, compact fluorescents have sold fairly well in the US. They save customers money. Utilities promoted and subsidized CFLs, particularly in California. Walmart (NYSE:WMT) pledged to sell 100 million of them. Time magazine put one on the cover. By 2012, CFLs represented 27 percent of the bulbs installed in the over 3 billion medium screw-based sockets in the United States, according to a Navigant study quoted by NRDC. Other researchers put the number lower, about 20 percent,...
Ten Solid Clean Energy Companies to Buy on the Cheap: #6: Sharp Corporation (SHCAY.PK)
I don't write frequently about solar stocks, especially photovoltaic (PV) manufacturers. While the industry is almost certain to be a spectacular growth story, it's also a story that everyone already seems to know about. Trader Mark put it well: "these stocks are too driven by retail hands." The PV story clicks with people, and when that happens, they often buy stocks with little regard to what they are worth. PV stocks are so psychological, we'd all do well to lie down on a couch before buying. As the IRS is unlikely to allow psychotherapy as an "investing expense," I...
Smart Grid Stocks For The Obama Stimulus Package
A few weeks ago, I wrote about how a new Obama administration would renew with Keynesianism (i.e. large-scale counter-cyclical infrastructure spending) but with a green twist to: (a) get the US economy out of its funk and (b) propel America into the 21st Century by providing a massive push for its green industries. I discussed certain rail stocks and electric grid stocks that could benefit as a result. By-and-large, I've been right on both counts about the President-elect's strategy (i.e. Keynesian and green), but I did forget to mention an important part of the plan's focus:...
Energy Recovery Recovers Its Own Energy
by Debra Fiakas CFA Energy Recovery (ERII: Nasdaq) has announced a breakthrough license of its hydraulic fracturing pump to oil and gas patch service provider Schlumberger (SLB: NYSE). Called the Vorteq by Energy Recovery, the pump features the company’s core pressure exchange technology, representing an entirely new approach to driving the chemical-laced water producers send deep into the earth to extract oil and gas. Energy Recovery develops and markets components and equipment for fluid flow and pressure cycles found industrial processes. Its patented pressure exchange devices are designed to take advantage of energy created in...
Is Cree, Inc. (CREE) Likely to Burn Out?
Tom Konrad, CFA Pioneering light-emitting diode (LED) maker Cree, Inc. looks overvalued. Light-Emitting Diodes, or LEDs, can be made to shine more brightly by increasing the power to them. This has the unfortunate effect of overheating the leads and shortening the lifespan of the LED. A similar effect may soon hit the stock of LED maker, Cree, Inc. (CREE.) Since I began the tradition, Cree has been a mainstay of my annual portfolio of ten stocks for the next year, published each January (See the 2008 and 2009 lists. The Cree-free 2010 list is here.) LEDs have been among...
How to Build a Cleantech Company Without Huge Investment Capital: A Case Study
David Gold While many cleantech companies require very large amounts of capital in order to get to market, there is a quiet group of cleantech companies bucking that trend. Companies like Heartland Biocomposites (Green Building Materials), RealTech (Water Testing) and TerraLUX (LED Lighting) all built significant and growing businesses with compelling intellectual property and did so initially without multi-millions in capital from venture funds (let alone tens or hundreds of millions). Because TerraLUX is one of our portfolio companies and I therefore know them best, their story is one I am able to share. TerraLUX boasts...
Lights of Energy Focus
by Debra Fiakas CFA It is the season of lights. Lights for Hanukkah. Lights for Christmas. Energy Focus (EFOI: Nasdaq) has been having a season of lights all year. The company reported $62.3 million in total sales of its LED lighting products in the most recently reported twelve months. Customers included large business and industry, property owners and the military. The oil and gas industry is an important market vertical. Energy Focus really shines for the U.S. Navy with its explosion proof LED globes in all the colors the Navy needs to provide military personnel safety...
The Pros Pick Three Green IT Stocks For 2014
Tom Konrad CFA Green 2014 image via BigStock Being green is not all about wind turbines and solar panels. In fact, it’s usually greener to be smarter about using what we have than to replace it with something new, no matter how green. My panel of professional green money managers understands this. When I asked them each for their top three green stock picks for 2014, there were as many picks focused on smarter resource use as there were solar stocks. I recently gave...

Power Integrations Enables Manufacturers to Earn the ENERGY STAR Label on External Power Supplies
Power Integrations Inc (POWI) announced that its EcoSmart technology enables manufacturers to earn the Energy Star label for their external power supplies. An expansion of the Energy Star program announced this week by the U.S. Environmental Protection Agency addresses external power supplies, the adapters that power such products as cell phones, MP3 players, digital cameras, PDAs and many other household and office devices.
Ameresco (AMRC): Clean Energy One-Stop Shop
Tom Konrad CFA Contrary to common belief, the greatest barrier to the adoption of clean energy is not the cost. In many cases, cost is not a barrier at all: it's an advantage. That's because energy efficiency measures are usually so cost-effective that they not only pay for themselves, they can often pay for the addition of flashier clean energy technologies such as solar and wind. For institutions in the Federal and MUSH (Municipalities, Universities, Schools, and Hospitals) sectors, the main barriers are lack of capital and expertise. Lack of capital arises because such institutions traditionally consider...
