MikePA,
We use the most oil and energy per person. Energy use can be summerized into three catigories;
Transportation
Housing
And all that stuff we buy
Transportation has largely influanced the US. With the introduction of the car at a time of tremendous US growth, it was easy for us to live "out of town". At the same time, 70% of US citizens were involved in the ag biz. Most of Eurpoe was established before the car with concentraited populations in cities. Most European have 5-6 story buildings as far as the eye can see. Mass transist was not only easy to adapt to but almost impossable to own and park a car. I work for a company in Vienna but also travel to Milan, Prague and other smaller cities. Mass transit costs about $1 usd for 45 min of travel. Metro system covers the city corner to corner, and buses cover the rest. Trians go between even the small cities. In the end, you can travel faster, cheaper and best of all you don't have to finding parking! Have a few too many beers with the boys, no problem! We fly everwhere. I bet I fly the Asia, 4 times a year mostly just to to "meet and greet". Europe, 5+ times a year. In most cases, a conference call would do.
Housing. We lve in big houses, plain and simple. I'm pushing nearly 3800 sq-ft with just my wife and two dogs. I have rooms I have not looked into in months. We keep the house at 74/70 Summer/Winter. I takes a lot of energy to build/heat-cool/maintain a house.
All the crap we buy. Walmart has built a biz on disposable stuff. Yea it's cheeper, so what the hey, I'll take two. TVs in every room! And don't get me started on Hoiliday gift buying! All this stuff we buy has some oil content, energy to make it and energy to deliver it and often energy to run it.
We are the biggest economy in the world. Were kind of a perpetual motion machine; buying stuff, using energy all paid for by the jobs of making stuff, big houses and more cars. When the day comes and were not the ones with those jobs "making stuff and we have to import that enery", we will see our perpetual motion machine grind to a halt.
