As I’ve mentioned, I receive several new clean energy business concepts per week, mostly rooted in proven technology.  The scientific mechanisms behind solar, wind, biomass, hydrokinetics and geothermal are all very well-established, and have been for a great period of time.  Every day there are improvements, and in some cases, important ones, and that’s a good thing.  But with each email I open from an inventor somewhere on the globe, I’m constantly hoping that I’ll get something legitimate but really new – not just a claim at an incremental improvement on an old technology.

Like most people, I judge the legacies of civilization’s finest contributors to the arts and sciences by how far advanced their contributions were from the work of their predecessors.  Here’s a quick story on the subject:

altattributeAfter we’ve spent an entire winter at home, it is finally time to open the windows, letting the fresh spring air in. Its time to chase away the cobwebs and bring out the best of our home. The following tips will cover both cleaning and some simple organizing you can do to stick to a more green outcome of your spring cleaning:

altattributeA colleague sent me this piece on the roadblocks that the utilities are throwing up to impede distributed generation.  He notes, “Everyone will decide where they come down on these issues, but the utility industry is now using a monopoly position to work against battery storage, solar, and independent electric vehicle infrastructure; they are stunting progress.  Now the industry will talk back, and so will the younger generation.”

You’re absolutely right, my friend.  There are huge pressures mounting up associated with utilities and distributed generation.  I’ve always advocated for a wholesale reform in the way utilities are regulated that is fair for all concerned while encouraging the things that are obvious social goods: distributed generation, storage, renewable energy, smart-grid, and, ultimately, V2G.  That our society allows the utilities to work actively against clean energy is stupid, to put it kindly.

Never at any other time in history has it been this easy to travel half-way around the world at a moment’s notice. In the early 2010s, flying to some of the greatest and most beautiful cities and regions in the world is child’s play indeed. And with rising airline competition (including those budget airlines) flying is becoming cheaper and cheaper. These new developments have opened the world for more and more people to see and enjoy, and it’s a fantastic time to be alive.

However, the increase in air travel around the world is not without its own issues and concerns, especially in relation to how it can impact our environment.

Like many other developed countries around the world, Australia have been committed to pulling out all the stops when it comes to the preservation of the environment. On a recent trip to the land down under, I was particularly impressed with this nation’s response and commitment to creating a more sustainable way of living for its citizens, and those who visit from abroad. I believe Australia could become a model country on sustainable living, and other nations would be wise to follow in their path.

I just got back from a long lunch with a brand new intern here at 2GreenEnergy — Louis de Saint Phalle.  A high-powered intellectual (he speaks five languages, and is highly educated, especially in economics and the physical sciences), Louis wants to research and write about a subject close to my heart: the national security implications of energy policy.

I promised that as soon I got home, I’d jot down a some notes on the subject that could inform Louis’ work, and so here are a few ideas for subject matter:

I just got off the phone with a bright new intern at 2GreenEnergy, Avdit Kohli, who’s wrapping up his master’s degree in electrical engineering at Northeastern University in Boston.  Insofar as Avdit’s main interest at this point is the technology side of solar photovoltaics, I told him that I would assemble a list of questions, then suggest that he pick one for the topic of a white-paper that he could develop for publication on our website.

Rather that send him his list privately, I thought I’d create a blog post and just send him the link.  Here’s the list:

The people at Tesla Motors are almost as good at making videos as they are at building cars.  Here’s a four-minute story of a guy whose job entails building run-of-river hydro plants, using the enormous water resources of Norway.  He enjoys skiing, and, between runs, he uses his cell phone to check his range — 471 kilometers — more than sufficient to get him home to his pretty blond wife.  But if it weren’t, he could stop off for a cup of Joe at one of the numerous Tesla Supercharging stations along the way.  

How does he get around to all these functions – in the dead of the harsh Scandinavian winter?  Easy.  His ultra-reliable Tesla Model S.  Not a bad life.

Among my planned stops today is an exhibit of the art of Carl Jung (pictured here in 1910).  My only studies in this area take me back to my junior year in high school, where I was lucky enough to be a part of a fabulous seminar that introduced a small group of us to the theories of Freud, Jung, Erikson, Maslow, and a few others. 

All these years later, I wonder if Jung’s concept of the collective unconscious isn’t rooted in a profound truth.   In his own words:  

“My thesis then, is as follows: in addition to our immediate consciousness, which is of a thoroughly personal nature …, there exists a second psychic system of a collective, universal, and impersonal nature which is identical in all individuals.” 

Don’t we need some sort of theory to explain (more…)

Writing for RenewableEnergyWorld, my colleague Jennifer Runyon begins her recent article on ExxonMobil and climate change:

We don’t cover climate change news all that much here on RenewableEnergyWorld.com. The reason for that is that we view climate change as just one bullet point in a list of reasons why renewable energy make sense: energy independence, grid stability through decentralized generation and resource depletion are also on that list.

I’ve known Jennifer for many years, and I respect her deeply, but I don’t follow her logic here.  She’s right, of course, that climate change is only one of many reasons to favor renewable energy over fossil fuels, just like cancer is only one of the many diseases that can kill you.  But I’m not sure that’s a reason to pay little attention to it.
