When we lived in a s&b we both had to commute five days a week and did errands and stuff two days a week. The gas usage was equivalent to what we use now - about 30 gallons per week.
When we lived in a s&b, we probably used the US average of 80 gallons of water a day. Now we use that in a week.
When we lived in a s&b, since we couldn't move our house when the weather got uncomfortable, we had to use quite a bit of heat (natural gas) during the winter and A/C (electricity) during the summer. Our house was 1500 sf. Now we move to where the weather is good, and avoid using either much of the time. We also have 600W of solar, which provides for most of our needs. It doesn't hurt that we are only heating or cooling 300 sf.
Are we more conservative (in the resources sense)? Absolutely. Which means we also 'conserve' quite a bit of money.
