Sunday Train: The Two Transitions to A Renewable Electricity Supply

The topic for this week’s Sunday Train was brought to my mind when I listened to the Energy Gang podcast. They were discussing the question of whether “CSP (that is, concentrated thermal solar power) is dead”, and the always entertaining, but not uniformly informative, “energy futurist” Jigar Shah declared that “CSP is dead” (segment starts 30:29), backing the claim up with a set of bullet points that fell far short of supporting the claim. And listening to the set of bullet points, it seemed to me that he was talking in the context of the phase of the transition to renewable energy that we are presently in, and ignoring the phase of the transition that we will have to pass through if we are to survive as a national economy and national economy.

In short, he seemed to be talking more as an energy presentist than an energy futurist, claiming that there was no plausible position for solar CSP power based on both the technology currently rolled out for a technology that is experiencing rapid development, and on context of renewable energy being added to an energy system which is untenable over the long term.

But I do not mean to single out Jigar Shah, since as I have recently been exploring various discussion spaces talking about various issues in the roll-out of renewable energy, cross-talk between the different phases of the transition to renewable energy seems to be commonplace. So what I wish to write about this Sunday afternoon is the “Two Transitions” to renewable energy: the Current Transition and the Next Transition.

Sunday Train: The Solar Fight, Is Going Right, Deep in the Heart of Texas …

Well, what do you know? I look around, and see a story saying Solar power gains momentum after long struggle in Texas. And not in “Grist” or “Solar Energy News!” or any such … but in the Dallas Morning News Business section from Wed, 4 June 2014.

According to the story,

Recurrent announced plans last month to build a 150-megawatt solar farm in West Texas after signing a 20-year power purchase deal with Austin Energy. That comes just months after First Solar, one of the world’s largest solar companies, began construction on a 22-megawatt farm near Fort Stockton with plans of eventually expanding to 150 megawatts.



And an even more dramatic acceleration could be ahead. Solar developers have been flooding the state’s grid operators with applications for more solar farms, close to 2,000 megawatts worth, said Warren Lasher, director of system planning for the Electric Reliability Council of Texas. “It’s hard to say how much will actually get built,” he said. “It’s been this way for more than a year. But it’s a significant increase from before.”
