If you read Vinod Khosla’s critique of German environmentalist Herman Scheer, then you’ll want to read this retort from the man himself. Scheer decided to respond to Khosla by writing a rebuttal for CNET’s News.com. In a nutshull, he calls Khosla’s viewpoint naive, contradictory and an example of established forces trying to perpetuate the centralized power infrastructure that has served and made profitable a handful of the world’s biggest power suppliers. Scheer makes some solid points here — it will be interesting to see how — and if — Khosla replies.
Before you read Scheer’s reply, I do want you do read the following comment that Khosla posted on this blog: “I love PV and am invested in PV but don’t believe it can replace 50-100 per cent of coal… we need something that can match the scale and ‘utility requirements’ of coal at the price of coal-based electricity.”
Until cheaper, reliable and large-scale storage is available, this won’t happen with solar PV. I’m surprised that Scheer didn’t address this point in his reply. I think the debate between these two is not solar thermal power versus solar PV, but rather solar PV as a majority of the world’s power versus solar PV as a restricted minority player.
