Apple trees produce apples. You can eat the apples year after year or chop down the tree and burn the wood to stay warm or build furniture. But you won't get more apples. When we consume a resource as fuel, we use some of the energy, waste some, and release by-products into the biosphere. This is inefficient, expensive, nonrenewable, and nonsustainable.
