Energy and other commodities become more expensive when the demand is high, raising the cost for everyone. When energy costs skyrocket, the price of food goes up, too, making it harder to feed a family on a tight budget. When we conserve resources like fuel, there's more for everyone and costs stay low. Insulate your home, buy energy-efficient light bulbs and walk to the store or to school instead of driving. Buy your produce locally, too, from a farmers market or food cooperative. Locally grown foods and locally manufactured goods typically use less energy because they incur are fewer transportation and staging costs.
