Improvements in Solar PV Come in Many DimensionsWe all know that our world is becoming increasingly capable of migrating away from fossil fuels, and the plummeting costs of renewable energy are the chief driver.  But what factors lie behind this declining cost structure?  Actually, there are several.

In the world of solar PV, one of the key issues is scale, i.e., the benefits that accrue to mass production.  But, arguably, advancements in materials science, at least in the long-run, will be of even greater value. (more…)

Sustainable Fishing and Civil DisobedienceAs you read this post, the crew aboard the Greenpeace ship “Esperanza” (or “hope”) is busily destroying fishing lines that catch tuna for Walmart in a most barbaric fashion, killing obscene numbers of other aquatic animals.  Is what Greenpeace is doing legal? Hardly. Is it right?  By my wits, absolutely.

We’re fortunate enough to live in a world where civil disobedience is flourishing;  it’s an important and well established tool in dismantling injustice.

If you would like to sign the petition demanding that Walmart cease these horribly abusive fishing practices, just click the link above.

Impressive Pace of Development in Hydrokinetics I’m rooting hard for my friends at hydrokinetic start-up Littoral Power Solutions to develop their product quickly and get into the game while there is still time. There is never a good time for dawdling in the renewable energy industry,  and that’s especially true given the progress that GE has made recently in this space, with its new turbine engineered for low-head run-of-river hydro.

While it’s far from a pure-play renewable energy concern, GE, with its recent purchase of Alstom Power, moved another step in that direction.  What’s more, it’s obviously investing considerable resources in this arena.  That’s really good to see, as it re-enforces the notion that we see all around us, the rapid migration to clean energy resources.

Understanding What Environmental Engineering Can Do for Your CommunityEnvironmental engineering primarily touches two sub-fields, civil engineering and biology. But each of these, in turn, is very broad. The field applies to everything from our global environment on down to the local level and interacts with other disciplines as diverse as space science, climatology, architecture, and geology. We notice it most at the local level, where we live.

The Local Environment (more…)

How the Media Is Ruining the United StatesHere’s a video I put on my Facebook page, with introduction: Those seeking to know why things in our country are so screwed up need look no further than this.

My old friend Steve Vachss writes:  This woman makes some good points. Nevertheless, she misses one fundamental reality. The media are not there to serve the public good or to provide fair coverage. I agree with her that TV “news” has been unwatchable for the past year, due to the political nonsense she fairly describes. (more…)

Ethical Handling of Refugees Is Essential to Global SustainabilityHere, Peter Sutherland (pictured), Special Representative for the UN Secretary-General for International Migration, speaks on the moral issues surrounding the processing of refugees.  IMO, no one has ever said something like this in a clearer and more compelling way.

Curiously, the concept of nationalism lies at the core of his statement, reminiscent of the video message that Arthur C. Clarke left us: “I hope we’ve learnt something from the most barbaric century in history — the 20th. I would like to see us overcome our tribal divisions and begin to think and act as if we were one family. That would be real globalisation…”

asdaHere’s a petition I just signed regarding the family pictured here.  It has very little to do with environmental issues, though a great deal to do with figuring out who we are as a nation.  If it doesn’t make you angry that this is happening in the U.S., you have a far more even temperament than I do.  (more…)

Note on Linguistics as it Applies to the Subject of SustainabilityIt’s the birthday of 20th Century philosopher Ludwig Wittgenstein, known for his contention about the role of linguistics in determining one’s capacity to perceive the world.  He wrote: “The limits of my language are the limits of my mind. All I know is what I have words for.”

This is a very interesting assertion, but I’ve never found it compelling.  There are potential thoughts and feelings that are unavailable to us because we don’t have words for them? It seems more likely that we make up words that describe new objects and feelings, and thus one does not limit the other. (more…)

What Force Does the Paris Agreement on Climate Change Carry?It should come as no surprise that there are people referring to the Paris Agreement on climate change, which 175 countries signed last week as “farcical,” on the basis that it is non-binding.  It was probably these people’s ancestors who said the Declaration of Independence was a farce because the British had a big, well-equipped army that would be tough to beat.  (more…)

175 Countries Sign Paris Agreement on Climate ChangeIt’s strange that such good news on a grand scale can receive so little coverage in the mainstream media.

The countries of the world have agreed to work together to mitigate the potentially catastrophic effects of climate change.

In some publications, this appears on page 6 next to an ad for used cars.  I choose to give it a bit more prominence.
