Celebrating the Things that All Humankind ShareIt’s the birthday of anthropologist Louis Leakey.  From the Writer’s Almanac:

In 1948, Leakey and his wife found one of the earliest fossil ape skulls ever discovered; it was between 25 and 40 million years old. It is now believed to be the skull of the ancestor of all large primates, including humans. Then, in 1959, they turned up another hominid skull, which was 1.75 million years old. It was the oldest skull of a close human relative ever found at that point, and it helped persuade other anthropologists that Africa was indeed the place where human beings had evolved.

It’s a shame that our daily lives contain only occasional reminders of our common humanity and its many profound implications, e.g., our rights as people and our duties to treat one another justly and kindly.  And now the consequences of getting this wrong are irreparable, as suggested by yesterday’s 70th anniversary of the nuclear explosion over Hiroshima.  Note: according to Bulletin of the Atomic Scientists Nuclear Notebook 2014, the total number of nuclear weapons is estimated at 10,144.

It’s a good thing there are no hateful bullies running for U.S. president in 2016.  Oooops, strike that.

The Most Innovative New Advances in Green TechnologiesIn 2015 the human race is at the peak of technological advancement, with some form of clever device or product making its way into pretty much all aspects of our day-to-day lives. On the most part these are to provide us with faster and more efficient goods and services, however when it comes to helping us to live greener lives, there are some incredible technologies available for us to use. Again, these are practical in their application. but the important difference that sets these aside is that they are more eco-friendly. (more…)

From a Kind-Hearted Reader in ZambiaHere’s a little exchange with a gentleman by the name of Ken from Zambia, who’s been following my work on clean energy investment opportunities.  Out of modesty, I normally wouldn’t publish something like this, but I couldn’t resist in this case:

Ken:  You’re a legend!

Craig: That’s what my mother says, but I thought she was probably the only person on Earth who ever had that thought.

Ken:   Haha… well at least you know now – she isn’t!

How to Optimize Your HVAC System for Maximum Home Energy EfficiencyNow that the warmer months are here, it’s not enough to have an air conditioning unit. Air conditioners need special maintenance to ensure they’re running at optimal levels and to ensure that cooling costs stay at a minimal amount. The home’s HVAC needs to be maintained to ensure proper heating, ventilation and cooling. Consider these tips. (more…)

Who's Your Landscape Architect?Here’s a story that’s made national news in the last few days and for good reason: it’s about a battle that pits people who want the land in front of their houses to be ecosystems for the species that would have occurred there in nature: frogs, clover, snakes, insects, tall grasses, etc.—against the rules of their home-owner associations that call for manicured and irrigated lawns. The people under attack want nature to be their landscape architects; their assailants claim their rights to make rules that preserve their rights to certain aesthetics. (more…)

Clean Energy ArgonautsCan you define the word “argonaut?”  I couldn’t, until this morning when the good people at dictionary.com made it their “word of the day”: a person in quest of something dangerous but rewarding.

One could say that 2greenenergy readers are argonauts for clean energy.

Philanthropy in Africa Can BackfireA reader points out that efforts to bring education and clean energy to the poorest of the poor in Africa only creates further dependence.

It’s true that giving things away is antithetical to the concept of establishing commerce. For example, every megawatt of solar we install as an act of philanthropy is a megawatt of solar that a vendor cannot sell. What would be best is the stimulation of these economies, and the establishment of social conditions in which women are not encouraged to have a dozen or more children.

A close friend offers an astute comment based on an observation he and his team made at a certain philanthropic organization:

1.       Let the Gates Foundation concentrate their resources on keeping more people in Africa alive.

2.       We should concentrate on making being alive more worthwhile:

a.       Address abject poverty by making environmentally benign energy available to all at an economically accessible cost.

b.      Energy is the underlying source of affluence.

c.       It has been demonstrated that affluence is a “cure” for excessive fertility.

 

 

 

 

 

 

 

 

 

Climate Change and Our OceansIf you’re wondering about the impacts of rising levels of CO2 on ocean physics and chemistry, you’ll want to check out the article linked here. Damage to key marine and coastal organisms, ecosystems, and services is already detectable, and will face high risk of impacts well before 2100, even under low-emissions scenarios.  Immediate, substantial reduction of CO2 emissions is required to prevent the massive and mostly irreversible impacts.

International agreements on climate change have proved elusive thus far, but even if we get what we’re hoping for here, we tend to overlook the influence we’re having on our oceans.  As the authors note:  any new global climate agreement that does not minimize the impacts on the ocean will be inadequate.

Energy “Propaganda”I mentioned earlier that Alex Cannera, the core participant in the on-going pro-nuke email thread I read, really doesn’t dig renewables, and feels compelled to take a swat at solar and wind at every available opportunity.  When someone else agreed with me and questioned his judgment on the validity of renewables, he wrote:  (more…)
