A dispassionate observer might wonder why the debate is concentrating on electricity generation since its contribution to CO2 emissions is about one-fifth of the total, whereas transport, heating and industrial processes account for four-fifths. Casting about for the least unpopular "solution" to the problem, politicians find a seductive answer: wind power.
