When it came my turn to ask a question, I voiced my concern about a recent article in the Wall Street Journal that noted how billionaire Warren Buffet had recently purchased Burlington Northern Railroad, betting that in the future, ethanol (made from corn) is going to be a major fuel source and that railroads are going to be the key to getting that corn to refineries. Buffet is placing a bet on the future of our energy needs, and that bet may make him yet another fortune. That's okay-that's capitalism at its finest-but what happens when Midwestern farmers decide it's more profitable to plant corn and plow their fields to the edges than it is to preserve pheasants or keep their land under Conservation Reserve Program protection? In response, the Secretary again reminded me of the balance we must strike, as a nation, between energy use, habitat preservation and the need for recreational lands of all types. That's when I really starting thinking about the obligation each of us has to help wean this country off its addition to oil. There is a lot we can do to help ease our energy needs wherever we live, even in the smallest of ways. We've all heard about turning downn our thermostats in winter and using the AC more sparingly in summer, but how many of us actually put that into practice? We can also turn down the hot-water heater and take shorter showers; run the dishwasher only when it's completely full; make sure the kids turn off the lights whenever they leave a room; and power down the computer at night. And, of course, we should drive the most fuel-efficient cars and trucks available, carpool, use public transportation and even walk or ride a bike to work or to the train station when the weather permits. These things might seem silly-they're so basic-but if everyone in the United States simply maintained the air pressure in their car's tires at the proper level, they'd get better gas mileage and we'd save millions of gallons of fuel every year.
