NewScientist’s January 28 issue is likely to unsettle clean energy advocates — but it is worth the read.
The cover article, “Power paradox: Clean might not be green forever,” posits that even renewable energy can warm the planet, and eventually change climate, if we continue to ratchet up power production to serve our ever 
Energy efficiency in the U.S. is much light and little heat — literally. Government policy pays a great deal of attention to saving electricity, but focuses little on the thermal energy we waste.
“Policy is electricity-centric in the U.S. Unless you are making kilowatts, the most efficient investments are off the radar,” sa 
I have a new favorite word — aggregation. At the risk of sounding like a reporter, I'm going to summarize a pre-holiday news story you might have missed but need to know about. 
Securitizing renewable energy networks from cyber-attacks is not complicated by their oft-cited operational headache of intermittency, but rather by their separation from a utility's control system, said smart grid executives at the Gridwise Global Forum in Washington, DC in early November. Though renewable intermittency adds to the challenge of stabilizing a grid, the forum revealed new evidence of real-world smart grid load shifting that continues to chip away at the tired argument that renewable energy cannot successfully integrate into a legacy grid. 
This is the era of Big Oil. Could the next be the era of Big Efficiency?
A new report by the American Council for an Energy-Efficient Economy suggests the possibility. Re-invented with today’s smart energy technologies, energy efficiency could displace 40 to 60 percent of our total energy needs by the year 2050, according to The Long-Te 
If there was one key takeaway from the most recent RenewableEnergyWorld.com and Solar Power-gen webcast it was that the year ahead will be difficult for large-scale solar power development due to poor access to capital, an uncertain policy landscape, the pending trade case against China and module prices that are too low to support a healthy indust 
Once again, John Petersen has gone too far with his petrol-head arguments against Electric Vehicles (EVs.) 
Building transmission to accommodate utility-scale renewable energy generation in the U.S. is seen as essential by much of the renewable energy industry. But can it be justified? Doing so will necessarily involve constructing some of the longest stretches of wire ever undertaken in this country. Much of the best wind and solar resource is located quite distant from the load. Ultimately, thousands of miles of huge power lines will have to be built. It is not illogical to ask whether investment in such massive infrastructure "costs too much and provides too little." It is also not illogical to answer "no," not if the value proposition is laid out appropriately and a well crafted policy and regulatory approach can be established that effectively addresses the issues. 
On December 16th I wrote: "My favorites for a strong 2012 include AONE, MXWL, AXPW.OB, ZBB, JCI, ENS, ACPW and XIDE. They all merit serious attention from investors who want exposure to the energy storage sector." Since then four of my favorites have bottomed and turned sharply higher while the Pride of Palo Alto endures a short circuit. The following table compares today's closing prices with the December 16th closing prices for those five companies. 
Americans tend to beat themselves up over their imperfections. We eat too much, watch too much TV and owe China too much money. Despite all of our sloth, we can feel good about one area: our progress saving energy.
A report issued this week by the Institute for Electric Efficiency found that we saved enough electricity to power almost 10 
The concept of the smart grid continues to mystify both utilities and consumers alike. Is it cost-effective? What is the best method for deployment? Is the public ready for it? Do we actually need it? 
Go ahead -- call me a hypocrite. I claim to be a cleantech venture capitalist yet I tell you here and now that I am not convinced of anthropogenic (human-caused) climate change (aka global warming). And I will audaciously tell you that my convictions on climate change in no way run contrary to my strong belief in the need for a cleantech revolution. 
If someone told me they could improve the efficiency of my computer so that it operates quicker, at no extra cost to me, I can’t imagine I’d turn them away. Yet, the energy efficiency industry offers a similar option for homes and businesses and at least so far, consumers aren’t flocking to the programs.
On-bill financing gives c 
I wasn’t able to attend the [frustrating] climate change talks in Durban, South Africa this year, although I would have loved to. South Africa is an incredible place to visit.
I say the talks are frustrating because they always seem to go the same way. The European nations and some smaller countries attend the meeting armed with serious data 
Electric utilities operated under a rarified business model for decades. Their customers were captive so they rarely had to think about what motivated them to buy. New government energy efficiency mandates have changed that, and done so with an ironic twist. Now utilities must figure how to get their customers to refrain from buying.
It’s no 
This week more than 750 large companies, small businesses and organizations sent a letter to Congress calling for a one-year extension of the Department of Treasury's Section 1603 Program. 
As I have said before, there is deliberate bearishness about solar power, much of it coming from the fossil fuel industries.
They ignore solar economics. Install a capital good now and money comes out day-after-day, year-after-year, literally for decades. Regardless of the current price of grid electricity you will, in time, pay for that c 
It’s December again (how did that happen!?) and our annual time for reflection here at Kachan & Co. So as we close out 2011, let’s look towards what the new year may have in store for cleantech.
There are eggshells across the sector for 2012. Global economic uncertainty is leaving some skeptical about the chances for emerging clean 
The U.S. Department of Energy’s reputation is now enshrined as the agency that Republican presidential contender Rick Perry wants to dismantle – if only he could remember its name. But a recent report by the American Academy of Arts and Sciences offers a different direction for the federal agency, one that may not make it more memorab 
President Barack Obama was in Australia this week and upset China and Indonesia with the annoucement of an increased miliary presence in this country, including 2500 US Marines to train and provision equipment in Darwin.
When the U.S. Marine Corp establish themselves a new home in Darwin, they will bring some seriously green equipment and ideas to
