ftfy.

The truth is that we could reduce emissions by living less affluent lifestyles, like, say, the 1950s. Smaller houses, fewer per capita miles driven, little or no intercontinental or transcontinental flights, less meat. But we won't. We cannot step off the hedonistic treadmill, even for a second, or the economy will collapse. And we can think of nothing worse than the economy collapsing. So we create a false dilemma, an impossible constraint system. So we will fail.

There is no need to fail. Just stop investing in obsolete technology. It's basic economics. Increase the energy efficiency of transport 3 fold by switching to electric cars. Increase the energy efficiency of electricity generation three fold by not wasting it on inefficient turbine based powerplants (coal, nuclear). Fossil fuels are downright disgusting in their inefficiency. There is a reason why we need so much primary energy. It's because when we burn coal 2/3 of the energy turns into useless heat. Heat is so useless you even get it for free by circulating water in black pipes exposed to the sun. The only advantage fossil fuels have is energy density and that they can be used as a chemical feed stock.
