Here’s a piece from the Executive Director of the Sierra Club, announcing that, after 120 years of endorsing only strictly legal actions, the organization for the first time will be embracing civil disobedience.  Two quick observations, if I may:

• It’s interesting that most Americans embrace the notion of civil disobedience as it applies to the past; we regard a great many of these people all through our history as heroes – starting, of course, with the Founding Fathers of the U.S. — and we have similar feelings of warmth for the people who followed their path – the Thoreaus and Abolitionists of the 19th Century and the women suffragettes and M.L. Kings of the 20th.  Our current president talks about the glory of Seneca, Stonewall, and Selma.  Yet some of the same supporters of past disobedience are prone to regard the present-day “Occupy” people or those blocking the Keystone XL Pipeline as “rabble-rousers” or “socialists” or worse. I find this curious.

• This announcement from the Sierra Club is one of hundreds of news stories appearing over the last couple of years that indicates a rising tide of anger against the direction that civilization is taking. As readers have come to know, I think this anger is well-placed.  We live in a world that is utterly dominated by the corruptive influence of Big Money, and there seems to be no way to revert this trend.  Want an example?  If you’re in Congress, insider trading is perfectly legal!  Want another dozen examples?  Just write me and ask.

I’d like to see your comments on the subject.

Whenever I come across an article like this on microgrids, i.e., “islands” of distributed energy generation, storage, and consumption that are not connected to a power utility, I look at the numbers. If I were a utility exec, how scared would I be about the incursion of microgrids into my turf?

This article projects that by 2022, microgrids worldwide will total 15 GW. Note that our current generation capacity is 15 terawatts, 1000 times that much. I suppose, putting this in perspective, that if you told me that I would lose 1/1000th of my market to an interloper over the next ten years, I could live with that without too much heartburn – especially considering that the total market itself will grow considerably over that period of time.

For readers who may feel a deep-seated feeling of grief associated with the environmental devastation that our society is visiting upon its home planet, this “train wreck in slow motion,” as it’s so often been described, here is a breathtakingly beautiful piece of writing from Carolyn Raffensperger, Executive Director of the Science & Environmental Health Network.

Whether it’s a book project or a blog post, I spend several hours every day trying to find the words that will best communicate the urgency of the environmental situation in a way that will inspire people to take on a spirit of hope and a commitment to action in a world where hopelessness and apathy seem to make more sense.  So, when I come across language with this level of power and brilliance, I don’t mind making a heartfelt recommendation. Trust me on this one, and check out this fabulous short essay.

It’s so easy to look at the levels of stupidity and corruption that have so overwhelmed the U.S. democracy over the last half-century and conclude that there is no hope.  Some of us may have thought that perhaps the Supreme Court’s 2010 decision “Citizens United” (granting corporations the right to spend as much money as they want to manipulate our elections in whatever direction suits their purpose) might have been the final nail in the coffin.

But then we look at the actual statistics associated with the movement to forward a Constitutional Amendment that would overturn Citizens United, and we see that it’s sailing right along!  (more…)

I just got back from Crestron Masters programming training where I learned about all of their new products coming out and currently available.

Crestron got its start doing programmable controllers and touch panels for the AV industry. In the process they created some very versatile controllers that allow for control over some very disparate and unrelated pieces of equipment. While controlling projectors/displays, screens, video switchers and audio equipment was their focus in the beginning, that rapidly grew into controlling lighting and HVAC also which then gave them control of over whole building lighting and HVAC systems. There is also interfacing with entry control and security systems. (more…)

A reader points out:

French automaker Peugeot Citroen has invented a brand new air-powered hybrid. The ‘Hybrid Air’ system uses compressed air to move the car’s wheels when driving under 43 mph. Peugeot says the new hybrid system should get up to 141 miles per gallon of gas. Models should roll out as early as 2016. Man, we hope it’s not all a bunch of hot compressed air!

So the car is powered by an internal combustion engine (at ~ 20% efficiency) that compresses the air, which then suffers huge efficiency losses when it’s decompressed?  That sounds like a terrible solution to me, and I find their claim dubious (unless the “car” weighs 80 pounds, or there is some other wild variable I’m not seeing).   

This, btw, is what has people enthused over EVs; the efficiencies of charging and discharging batteries are in the 90s (as high as 99%), and the efficiency of the motor itself, i.e., the conversion from electrical to mechanical energy, is in the low 90s as well.  Of course, the issue here is how the electricity is generated; if it comes from coal, that’s bad.

My thanks to AltEnergyStocks.com’s Tom Konrad for his recommendation that I buy stock in cleantech up-and-comer Maxwell Technologies! It’s up a mere 43% from when I bought it just a couple of months ago, not to mention 7.39% today — and the day’s not over. Woot!

I’m largely kidding with all this ebullience; I know that Tom recommended this for the long-term, and that the short-term spurt has been more a matter of luck than anything. But in any case, Woot!

Some days, I’m proud to be an American. Other days, I come across stuff like this piece on climate change, and I want to try to find a rock to crawl under.

Obviously, antics like this piece from Fox News, accusing all climate scientists of corruption, are theater rather than news, but that doesn’t make them any less embarrassing to our country.

H. L. Mencken said 80 years ago, “no one ever went broke underestimating the taste of the American public.”  But isn’t there a limit? Isn’t there anything these people at Fox won’t do for money?

If I had to pick a single theme that cuts across the business buzzwords that prevailed over the last half-century, I think I’d choose “convergence.”  The convergence of manufacturing and IT, of voice and data communications, of telephony and IT, etc.  And of course, our current fascination with bringing together the proliferation of web services, mobile devices, and emerging consumer lifestyles.

Here’s one not to be overlooked, however: the convergence of IT and OT (information and operations technologies) that pundits believe will drive a huge section of the business world over the coming decades.  I’m a believer as well, insofar as this whole subject is really the enabler of so much of what we’re doing in energy efficiency, conversation, and the migration to renewables. 

Take a few minutes, if you will, and look through these 17 “must-know” IT/OT technologies.  As you do, consider how important most of them are to moving our world in the direction of the sustainable generation and consumption of energy.

My friends at Eos Energy Systems tell me that far more than 95% of the world’s energy storage is pumped storage hydroelectricity (PSH) – which is one of the reasons they believe that their breakthrough in zinc-air batteries is so important.  We commonly think of PSH of requiring natural changes in elevation, since the cost of building such topographies would be cost-prohibitive – but is that necessarily true? 

Here’s a unique approach to energy storage that the Belgians are implementing, building a hollowed-out island (pictured at left) off the coast of West Flanders, enabling them to more than triple their wind capacity (currently 3%) from its North Sea wind farms alone, allowing them to replace one of their two 3,000-MW nuclear plants.

The article doesn’t quote the cost, but this does seem potentially viable in shallow and calm waters.
