BACKSTOP RESOURCE: A sustainable, renewable natural resource that is used in place of, and as a substitute for, finite, exhaustible natural resources that have been exhausted. A sustainable resource is one in which the amount used today cannot reduce the amount available tomorrow.The best example is solar energy. No matter how much solar energy we use today, the same amount reaches the planet every day in the future. A backstop resource is then a sustainable resource, like solar energy, that society uses after finite resources, like fossil fuels, have been exhausted. In fact, solar energy is often considered THE backstop energy resource. It represents THE "safety net" that's available when fossil fuels are depleted.

This derivation process begins with the consumption line, then adds investment, government purchases, and finally net exports. The process actually generates three alternative aggregate expenditures lines based on the number of sectors included (two sector, three sector, and four sector).
