Should We Censor Communication—Whether in Movie-Making or Renewable Energy?

Should We Censor Communication—Whether in Move-Making or Renewable Energy?For the first time in the history of Hollywood, filmdom is caught in a no-win situation: if Sony Pictures airs its movie exposing the insane brutality of the Kim Jong Un regime, it’s a near certainty that North Korea is more than crazy enough to kill innocent Americans—probably an enormous number of them.  I chose the picture for this post specifically for those who may be wondering if the regime is, in fact, sufficiently deranged; it features a few of the 80 Koreans who were executed by firing squad one recent afternoon for watching foreign films.  Thus Sony’s conundrum: releasing the film results in death; not releasing it endorses and encourages censorship—imposed first from the criminally insane—but what next?

Speaking of censorship, but on a completely different scale, for the first time in the history of 2GreenEnergy I told someone just last night that I wanted to sever dialog.  Read more ›

Predicting Energy Consumption in the 21st CenturyMy colleague Gary Tulie sent me this, explaining how energy use in the UK is falling, despite an improving economy.

I feel sorry for people whose job is predicting the energy markets of the future—and for precisely this reason.  Read more ›

The Endless Variety of Hydrokinetic Devices

The Endless Variety of Hydrokinetic Devices

For the reader who, for whatever reason, may be on a quest to check out every conceivable variation on the theme of extracting the kinetic energy out of moving water, here is Atlantis.  Note that a great deal of discussion refers to R&D in 2002 and 2006.  Not to sound cynical, but I think there is a reason for that, and it doesn’t bode well for their investors and other fans of this type of technology.

Re-invigorating U.S. Cleantech Innovation

Re-invigorating U.S. Cleantech InnovationI’m guessing the name Walter Feuchs is not a new one to many readers; he’s been in and around cleantech innovation for a very long time.   Here he writes:  (This document) provides an overview of innovations with a global perspective. Any questions?

Walter:  I don’t disagree with a single word you’ve written in your “Green Climate Fund” piece, and the prose is, as always, very clear and compelling. Read more ›

Discussion on “Free Energy”

Discussion on “Free Energy”A reader asks for my comments as follows:

I am not a technician but a Free Energy lover – (I’ve spent) more than 30 years trying to understand Nikola Tesla patents as the first approach to free energy.  (Now I’m studying):

• “Thermoelectric generator combination — solar ovens concentrate between 800 to 1000°C of heat, converted into electricity by means of Peltier modules

• KapaGen .. closest to Tesla’s free energy… inventor got too much pressure from the “police” and therefore does not answer me anymore Read more ›

Driving Participation in Waste-To-Energy

Driving Participation in Waste-To-EnergyA reader, part of the labor union IBEW 1933 utility workers in Southwest Florida, asks my opinion on a waste-to-energy matter:

I represent Glades Electric Coop (18000 meters and old style poor coop) and LCEC (200500 meters and more modern wealthy coop).  I personally believe the transition to renewables with interaction of the existing grid is a gift waiting to happen. I would like your thoughts on how to get members of theses coops (especially progressive renewable believers) to start participating in the trustee structures of the coops.

I’m afraid I’m not going to be of too much help–beyond rooting for you, that is.  Read more ›

No Energy Policy, But Good News on Cuba

No Energy Policy, But Good News on CubaAs we’ve seen, any move by the U.S. legislature that would send us in the direction of clean energy is far too contentious at this time.  Fortunately, our Congress has stumbled upon another good thing to be done in the world–one that happens to be almost totally noncontroversial:  rescinding America’s obsolete and hateful policy with respect to Cuba.

Humanitarians everywhere celebrate this and all victories–whatever form they take, whomever they affect, and wherever on the globe they occur. Here are 21 pictures that, according to the article, “say it all.”

Warren Buffett Loves Demand Response

Warren Buffett Loves Demand Response“Everybody knows” that demand response is going to be huge over the next decade.  How do we know?  Well, for one, Warren Buffett is investing in it.  And what exactly makes us believe that the Oracle of Omaha is so incredibly unlikely to err?   His $63.6 billion.

Don’t get me wrong, I agree that he’s right about demand response, and that he’s a fabulously brilliant guy overall.  But the logic above is faulty; it’s reminiscent of this classic scene from the American film City Slickers (1991).

Can Ocean Wave Energy Be Cost-Effective?

Can Ocean Wave Energy Be Cost-Effective?The more I read about this, and the more time passes (perpetually bringing down the cost of solar and wind), the more I doubt it.  Having said that, here’s an article on the use of wave energy in Africa.

The project developer writes:  The technology can achieve a power generation cost as low as USD 0.02 per kW (sic), …. compared to USD 0.03/kWh for coal, USD 0.12 for solar and USD 0.036 for wind. 

“Can” achieve?  Under what circumstances?  Sorry, but this is total horse hockey.
