Car Ownership and SustainabilityThere was a popular song here in the U.S. in the 1990s that began: “I believe that children are our future….”  This has always struck me as nonsensical.  The lyricist might have been thinking:  OK, let’s get started with a brave and bold statement….I believe that old people are our future…., no, wait a second; they’re going to be dead soon; let’s make that children, yes that’s much better.

Be this as it may, yes, he was obviously correct: young people are indeed our future.  That’s why it’s so gratifying to see that they lead the charge in a great number of directions that favor sustainability, one of which is a bold reduction in car ownership.  (more…)

Ocean Acidification and Its Many Terrifying ConsequencesThose of you who understand the basic chemistry of ocean acidification know that the excess carbon dioxide in the atmosphere is absorbed into the seas, momentarily creating carbonic acid, which almost immediately breaks apart into products that includes a hydrogen ion.  The ion then combines with the previously abundant carbonate molecule, the limiting reactant in the formation of calcium carbonate (limestone).  (more…)

2GreenEnergy Thanks All Its Contributors--And Steve Martin for a Highly Relevant QuoteI may have mentioned that we recently passed the 5,000 mark in terms of total posts here.  In fact, this is number 5,126–of which I’ve written 4,483.

When it comes to my stuff, I’m reminded of what (American actor, director, and comedian–pictured) Steve Martin said:  “Fortunately, persistence is a good substitute for talent.”

Thanks to all who have contributed.

What Will Become of Most Renewable Energy Concepts?Frequent commenter “MarcoPolo” (the original pictured left) writes:

While it’s true that some technologies do become mainstream innovations, most never fulfill the dreams of their supporters, and remain only hobbyist or small scale applications.

Like you, every week, I receive dozens of proposals by dedicated, enthusiastic (sometimes a little rabid and fanatical ) innovators, seeking to finance the development, or commercialization, of all sorts of wonderful new innovative concepts. I try to sort these into five categories: (more…)

Divestment from Fossil Fuels Is a Big Deal in Today’s WorldWe often hear that young people are much more environmentally conscious than previous generations, and we certainly have to hope that’s true.  It’s certainly the case with a young woman named Emma, who writes as follows:

As a trainee journalist…I’ve been lucky enough to be part of some really exciting projects…but there few things I find more exciting than a mass movement of people fighting back – and it’s hard to imagine a more important fight than climate change. (more…)

Covering the Subject of Synthetic Fuels for "The Hedge Connection"Here’s another monthly installment that I write for The Hedge Connection, where, in this case, I present a short introduction to the subject of synthetic fuels as a viable method of energy storage.

I begin with a reminder to Hedge Connection readers what 2GreenEnergy is all about, i.e., that it represents an effort to bring together entrepreneurs in renewable energy and related disciplines with the sources of investment capital they need to take their business concepts forward—a task that has required me to review literally thousands of ideas (more…)

Pope Francis’s Messages Don’t Resonate with EveryoneIt’s hardly a surprise that the right wing here in the U.S. is taking issue with the Pope’s involvement in politics.  Hardly a week goes by without the Pontiff’s explicating some aspect of God’s will and how He commands that we care for one another and the environment around us.  These concepts have profound implications as to how we conduct our society and govern ourselves, and predictably, we have Republicans suggesting that His Holiness stay out of the political arena and limit his concerns to strictly religious matters.  (more…)

Re-Establishing Our Relationship With Our Power UtilitiesBrace yourself for a plethora of stories like this: Utilities and consumers at war over the use of rooftop solar.  Fans of renewable energy object to the cap that NV Energy in Las Vegas, Nevada has placed on the number of homes that can sign up for its net metering program.  The utility argues that each new installation reduces the revenue base that is required to keep its utility financially viable, though this reasoning does not impress a number of different groups who are vocally objecting to the utility’s position.  (more…)

Air-powered Car – “Coming Soon”

Over the years, I’ve had several friends send me this “air car” concept.  It’s a terrible idea in terms of engineering and physics, but that’s not the most objectionable thing about it; it’s a bald-faced attempt at deceit. (more…)

Trans-Pacific Partnership: An Eco-Disaster in the Making

I just received an email that reads:

Craig, we won a big victory in the U.S. Senate on Tuesday—when Democrats voted against moving on fast-track legislation for the TPP (Trans-Pacific Partnership) agreement.

But the battle to stop a secret corporate trade deal is not over. (more…)
