Energy return on investment: Impact of societal energy yields on economic sustainability

Evaluating an energy source based on the amount of invested energy needed to access, use, and dispose of waste for a resource, is crucial to economic stability. Using energy return on investment (EROI) as a tool to measure the investment yield of an energy source provides a large pool of information on which future energy investment decisions cam be based. High yield energy sources are critical to maintaining current economic models, and should measure the ability of renewable energy to compete in the energy market.
