Here’s Nobel Prize-winning economist Paul Krugman’s recent column in the New York Times addressing the oft-discussed issue: Are efforts to achieve environmental sustainability necessarily damaging to the strength of the economy?

As usual, as we dig deeper into subjects like this, we learn that there are important complexities.

In this case, some efforts to decarbonize open up huge economic opportunities.

Krugman uses the “carrot and stick” metaphor and points out that carrots like financial bonanzas tends to work better than sticks, like taxes. Yet, in reality, our society is too far from where it was a few decades ago, where the consumption of fossil fuels becomes extremely unattractive the moment someone is asked to cover the costs of the environmental damage associated with climate change, ocean acidification, and loss of biodiversity.

Renewable Energy Concepts Can’t Violate the Laws of Physics

In the early days of 2GreenEnergy, my people and I were vigorously engaged in finding solid ideas in cleantech that needed funding in order to move forward.

I vividly remember a conversation with a guy in Maryland who was trying to explain the (ostensible) breakthrough that he and his team had made in hydrokinetics. When I was having trouble visualizing what we was talking about, he asked me to “think of it as a river in a box.”

“Oh!” I exclaimed. “You mean you take a box full of standing water, add energy to it get it moving, then extract that energy, leaving you with more energy that you added to it.”

“Exactly.”

I politely explained that the laws of physics, specifically the first and second laws of thermodynamics, make this impossible.

He wasn’t through, however, and insisted that, in his office, his people had constructed a “working model.”

Here’s where my tone descended into something less than 100% polite. I told him that he may think he has a working model, but he’s wrong; if he believes this, he’s ignorant; if he doesn’t, but is conducting this conversation anyway, he’s a fraud.

“But don’t you want to come see it?” he implored.

“No. Not only would not fly across the country to see whatever it is you claim to have built, I wouldn’t walk across the street to a “working model” of something that is theoretically impossible.”

I tell this story because the claim made at the upper left is essentially identical. You’re pumping water up out of a stream, and then claiming to extract more energy when the water flows back into the stream.

Of course, social media today is rife with complete crap like this. We’ve devolved to a point where defrauding money out of idiots is rapidly replacing baseball as our national pastime.
