CBS’s Leslie Stahl’s Viewpoint on CleanTech and Climate Disruption?  That Depends–Who’ll Write the Biggest Check? 

CBS’s Leslie Stahl’s Viewpoint on CleanTech and Climate Disruption?  That Depends--Who’ll Write the Biggest Check?Less than a year ago, CBS aired a “60 Minutes” segment hosted by Leslie Stahl, whose mission was to convince tens of millions of credulous, uninformed viewers that cleantech was a failure, and they, as taxpayers, had been fleeced.  Now she’s telling a different story, but why?

End of an Era – I mean “Epoch”

End of an Era – I mean “Epoch”I never memorized the names of the eras and the epochs used to describe geologic time, but I’ve heard several references recently to the idea that scientists are considering calling an end to the current epoch (the Holocene) and starting a new one, based on the profound impact that humankind has had on the planet (to be called the Anthropocene).

On Taking Care of Mother Earth – Another Thought

Here’s another remark for our reader who denies a duty to take care of our planet, expressing himself in this comment in my recent post:

There is no “Mother Earth”, nor are we required to be “good stewards” to anyone but our own best interests. 

This fellow seems prepared to throw away the entire development of philosophy of religion over the past 5000 years in favor of the thinking of Ayn Rand.  Read more ›

Adventures in Ocean Hydrokinetics

Adventures in Ocean HydrokineticsI had a nice chat with my brother yesterday during which he asked my opinion of a company called Hydro Alternative Energy (HAE).  Looking at their website just now, I notice they write:

(Ocean) currents can be thought of as rivers that exist within the oceans, with predictable directions, pace, and borders.  Then, the electricity generated by currents can be connected directly to the grid.  …. In addition to using ocean currents, electricity can also be generated by tidal flow.

Electric Transportation Will Provide Numerous Benefits

Electric Transportation Will Provide Numerous BenefitsAs pointed out in this article, the presence of electric vehicles plugged into our grid will one day provide a great number of different benefits, largely in terms of “ancillary services,” but also in terms of absorbing off-peak power, and, perhaps providing some power to the grid in times of peak load.  In addition, grid operators will be able to charge EVs at the precise times during the day that enable them to integrate the maximum amount of renewables.

When will all this happen?  It’s hard to say, because so many factors are moving at the same time: the smart grid/Internet of Things, the EV adoption curve, the development of different flavors of renewables, the build-out of our power transmission lines, the availability of other sorts of storage, etc.

On Taking Care of Mother Earth

On Taking Care of Mother EarthRecently, one reader made an impassioned comment on our need to take care of our planet, and another responded:

There is no “Mother Earth”, nor are we required to be “good stewards”, to anyone but our own best interests. 

I appreciate this very clear and concise remark.  In fact, I think that all of human relations comes down to this very point: we either feel a sense of love and duty toward the people around us …. or we don’t.  Read more ›

Run-of-River Hydro Projects in Southern Brazil

Run-of-River Hydro Projects in Southern BrazilEach month, I submit an article for publication in the “Hedge Connection,” a marketing platform for hedge funds and an information portal for investors, in which I extol the virtues of one of our renewable energy investment opportunities.  Here’s this month’s submission, in which I review a collection of run-of-river hydro projects in Southern Brazil.

Air Umbrella

waste energy and other environmental resources on frivolous junk

The message here is simple: If there is a way to waste energy and other environmental resources on frivolous junk, we’ll find it.

The product also has the virtue of flinging more rain on other people around the user. I’d like to see how this works in New York City, and how far the user would get before he was flattened by a fellow pedestrian.

Replacing Coal with Natural Gas

Replacing Coal with Natural GasAs I wrote yesterday, a wholesale replacement of coal-fired power plants with natural gas has short-term appeal, but an unacceptable array of long-term unintended consequences, e.g., creating an environment in which the development of renewable energy isn’t financially attractive.  The author of this piece agrees, and compares the idea to binge dieting, not a bad analogy.
