Scenarios are the primary tool for examining how current decisions shape the future, but the future is affected as much by out-of-ordinary extremes as by generally expected trends. Energy modellers can study extremes both by incorporating them directly within models and by using complementary off-model analyses.

能源建模人员应该在方案中更系统地探索极端

场景是检查当前决策如何塑造未来的主要工具，但未来受到异常极端因素和一般预期趋势的影响很大。能量建模人员可以通过将极端直接合并到模型中或通过使用补充的模型外分析来研究极端。
