Uninformed Critics (Often Pro-Nuke People) Attack Renewable Energy with Loud, Though Specious ArgumentsI’m often called upon to defend renewable energy against its critics.  Here are my words of rebuttal to Alex Cannara, a nuclear advocate who for some reason feels compelled to denigrate renewables at every opportunity.  My remarks are in italics below each of his assertions.

• There’s no such thing as “renewable” energy.  Remember conservation of energy? “Renewable” is a marketing term.

The word “renewable” doesn’t mean that we’re manufacturing energy from nothing, only that we’re taking it from sources that are virtually infinite and comparatively non-polluting.  The sun will be shining in our sky for the next 7.59 billion years, continuously bestowing our planet with 6000 times more power than we are consuming right now.  By contrast, since the dawn of industrialization, humankind has reduced the store of hydrocarbons in the Earth’s crust by over 50%.  That resource depletion alone is scary, when you think about it, though that’s the very least of our concerns with fossil fuels.

Using Comedy To Drive Home Important PointsIt’s remarkable how stand-up comedians can make serious points in extremely effective ways.  You’re laughing you butt off at the same you’re saying to yourself, “That’s EXACTLY correct.”   I’ve mentioned several times how Robert Morgan pulls this off so astonishingly well with his hilarious piece “The History of Oil.”

If you’re looking for a similar experience on a different topic, here’s Australian comic Jim Jeffries (pictured) tackling one of the most controversial subjects in the US: gun control. Part One, Part Two

American Is Exorcising Itself of “Citizens United”My recent post: The Social Contract and the U.S. Government makes the point that the American people are in the process of putting a spear through the U.S. Supreme Court decision “Citizens United.”

A reader responds:  Hi Craig. When you look at a map of the U.S., think of the people who live there. (more…)

Sierra Club’s “Beyond Coal” Campaign Has Been Incredibly EffectiveFor some reason, not everyone shares my approval of the Sierra Club. Say what you will, but their Beyond Coal campaign has succeeded in forcing the retirement of one coal plant every 10 days for 5 straight years. 200 coal plants altogether are retired or slated to be retired, out of the original 523 they took aim at. They’ve already surpassed their 2020 goal, and thus enlarged their mission: retire half of all coal plants by 2017.

Ponder this for a second; think about how few Americans understood this issue just 10 short years ago, and how pervasive it is in the public consciousness today. That’s really terrific work. Right on, guys.

Contemplating the End of EarthOf the 4700+ blog posts I’ve written here since 2009, several dozen contain the suggestion that our civilization as we know it may be headed for extinction within the next century.  What’s most likely to take us down?  Any of a number of things, but certainly the damage we’re wreaking on our environment has the potential to get the job done all by itself: (more…)

In the phone calls I place to my mother every few days, we sometimes talk about 2GreenEnergy, which, I’m flattered to say, she reads regularly. Last night she reiterated something she’s been telling me for years:  she sometimes has issues with my posts that are “tangential” to the basic notion of renewable energy.  My recent post on The Social Contract and the U.S. Government came immediately to my mind when she said that; I think I may be in trouble with her on this one….. 🙂 (more…)

Solar PV: Is Bigger Better?We’ve all had the thought: What are the relative merits of utility-scale solar PV vs. the distributed, rooftop version?

To be sure, there are numerous factors to be considered.  In terms of the levelized cost of energy for each kWh, no one doubts that the utilities can afford to build (or buy) power at a scale that is unachievable at the local level.   But what about the value to the local economy? The cost of power transmission lines?  The further entrenchment of monopolistic interests over those of the individual?

IMO, the author does a good job in the article linked above.

Last Tuesday saw the passing of novelist E. L. Doctorow at age 84 (pictured). I had written about him a couple times, as I was always tickled by what he said one time about his writing routine: “Here’s how it goes: I’m up at the stroke of 10 or 10:30. I have breakfast and read the papers, and then it’s lunchtime. Then maybe a little nap after lunch and out to the gym, and before I know it, it’s time to have a drink.”

Needless to say, I don’t compare myself to Doctorow or any other talented writer, yet I have to say that I share a fairly relaxed approach to the subject of preparing my books and blogging here at 2GreenEnergy and other sites on clean energy. The concepts spring up naturally from reading other people’s stuff – some of which inspire praise and support, some curiosity, and others rebuke. There really is no discipline to it at all.

Run-of-River Hydro in Brazil: An Opportunity Available for the TakingEven though it’s experiencing appreciable economic and political uncertainty, Brazil doesn’t seem to waver too much in its profound commitment to renewable energy.  The vast majority of the 1.8 GW installed last year was wind energy, and, while I’m a big fan (pun intended), I’d love to see more run-of-river hydro, a concept that I believe fits very well with Brazil’s natural energy resources as well as its electricity demand patterns, as I’ve described here, in my list of renewable energy investment opportunities.  Needless to say, my colleague who acts as the principle of the deal linked above, couldn’t agree more.

Advice to Solar PV Entrepreneurs: Begin with Market ResearchLast week, I advised two would-be solar entrepreneurs with a novel idea to validate its market appeal before spending money building a prototype or taking any other steps forward. As I suggested here and here, using the kindest and gentlest language I could muster, I urged them to use a small but definitive market research effort to corroborate their belief that an appreciable level of consumer demand exists for the concept.
