> I've yet to see an economy-rich energy-poor country Past performance usually doesn't predict future results. I'm not aware of any good or service that is not subject to diminishing returns from increased consumption. Keep increasing energy consumption and you start hitting other limiting factors like the availability of other resources, labor, population growth, food, etc. Energy can help with some of those but not all of them and not in a linear relationship. Eventually you hit the ultimate limiter: diminishing marginal utility of wealth itself. At some point you start to max out as a human. There are countries that consume more energy than the USA that are actually poorer and their higher consumption is a function of either climate (lots of HVAC) or the use of old inefficient technology (in which case poverty actually increases consumption). It really looks like the ultimate limits to growth (on Earth) are demand side limits to growth due to leveling off of population. Humans have fewer kids when they have more wealth and/or see more humans around.
