There's a heavy assumption in your comment that more energy = more happiness. I'm not sure if you actually believe that, or if you just haven't questioned it, but that seems untrue to me. There's a correlation between energy expenditure and comfort, but it's less clear to me that there's a correlation between comfort and happiness. In fact, I tend to think that too much comfort makes us unhappy in some ways. I definitely think Texans are pretty miserable in comparison to Sri Lankans.
