J'ai appris aujourd'hui le décès de David MacKay, un homme extraordinaire. Il a écrit L'énergie durable - pas que du vent! Triste, car il avait certainement encore des choses à apporter.
David MacKay is dead. A big hero, though I never knew much about him. But I did buy, read, love (and lend) his book Sustainable Energy Without the Hot Air. Download it, or watch the video, and learn you some science and realism. Take-away point: "If you want reliable (low-carbon) electricity supply in the winter, you need nuclear, and once you have nuclear, there's not much point spending money on wind".
