英文摘要：

The facts of global wanning and financial crisis increase uncertainty faced by investing in energy technology. Much of recent attention from worldwide researchers has been paid to decision-making process of energy technology under an uncertain environment This article reviews the application of uncertain investment theory, i.e., real option theory in energy techno-economic evaluation, from the perspective of three main energy technological routes for climate mitigation, that is, new energy, energy efficiency and carbon capture and storage （CCS）. As the international concern of global wanning and the inherent risk of global economy are rising, it would be increasingly important to evaluate economics of these technologies under such a background. Hence real options theory is expected to perform more and more widespread use.
