I'm pretty much of an ordinary citizen too. That tends to explain why I like to focus on the commuting end of the deal. I often mention the conversion of money to the gas, just for fun. Things like "here's a couple fifths of gas" or "here's a tip of a couple gallons and a litre of gas" are part of my common parlance. Energy is Money.

the ultimate of this style of thinking is that pennies are $60/gallon and quarters are $800/gallon. A $10,000 surgery job is 4 barrels of pennies! When thinking about large amounts of money, you can easally imagine a warehouse with drums full of pennies. A million bucks is 400 drums of pennies, 20 to a side in that warehouse. Imagine standing on a mezzanine looking down on the floor with those drums of pennies. There is a website about extreme numbers of pennies. (megapenny.com?)

More so than time, energy is money. What a businessperson calls "time is money" ends up being time * energy = money.
