Nuclear power, both fission-based and fusion-based, is yet another possibility for vast, reliable, secure, and environmentally safe primary energy. Here, too, there are technological obstacles, but they seem surmountable.
聚变和裂变产生的核能是另一种大量、可靠、安全且无环境污染的初级能源。这里同样存在技术障碍，不过看起来可以克服。当然，此外还有重大的政治、制度以及安全方面的因素，所有这些问题都需要适当处理。
