It's a reverse value proposition: the more we feel threatened, the more energy we spend defending, restoring, and asserting our value, and the less energy we have available to create value.
这是一个关于价值的逆命题：我们越觉得受到威胁，就会花更多的精力来防御、恢复和确认我们的价值，这样就剩下越少的精力来创造价值。
But she said an equally important use for the renewable fuels would be to store solar energy so it is available at times of peak demand, and overnight.
