把这一句，留给此刻的你

But that's not enough: To maintain energy security, one needs a supply system that provides a buffer against shocks. It needs large, flexible markets. And it's important to acknowledge the fact that the entire energy supply chain needs to be protected.

但这还不够:要维持能源安全，就需要一个供应体系，为冲击提供缓冲。它需要庞大而灵活的市场。承认整个能源供应链需要保护这一事实是很重要的。
