Counterpoint: If solar and wind are competitive, why all the aid?
In “Solar and wind are viable, not just ‘feel-good’ climate solutions” (Sept. 27), Jim Davidson made a Counterpoint to my recent arguments about green energy (“Feel-good solutions won’t solve climate change,” Sept. 22).
Davidson supports my championing of spending $100 billion a year on green energy R&D. He suggests that this is a new position. But I have in fact advocated it consistently for a decade, including in a front-page article in the British newspaper The Guardian in 2010.
