Why is it so difficult to wean ourselves from fossil fuels?

Why is it so difficult to wean ourselves from fossil fuels? The answer is a surprisingly simple one. A clarifying insight comes from comparing different energy sources in terms of their energy content. Using 1 million BTUs as a standard for comparison, let’s look at how much it costs to get that much energy from […]
