Nuclear energy presents a number of disadvantages, owing to concerns about safety and disposal of radioactive waste. Hydroelectric power is already widely used, while wind and solar energy are structurally sporadic and disparately available.
能源生产多元化的现有替代方案是有限的。由于对其安全性和放射性废料处置的担心，核能也有诸多劣势。水电已经得到了广泛应用，但风能和太阳能的利用在结构上呈分散状态，资源的分布也不均衡。
