Ross McKitrick has posted some thoughts on Earth Hour, as told to a journalist last year:
The whole mentality around Earth Hour demonizes electricity. I cannot do that, instead I celebrate it and all that it has provided for humanity. Earth Hour celebrates ignorance, poverty and backwardness. By repudiating the greatest engine of liberation it becomes an hour devoted to anti-humanism. It encourages the sanctimonious gesture of turning off trivial appliances for a trivial amount of time, in deference to some ill-defined abstraction called “the Earth,” all the while hypocritically retaining the real benefits of continuous, reliable electricity. People who see virtue in doing without electricity should shut off their fridge, stove, microwave, computer, water heater, lights, TV and all other appliances for a month, not an hour. And pop down to the cardiac unit at the hospital and shut the power off there too.
