各个水电开发计划都伴随一些大的环境问题,特别是在热带地区。然而,在自然保护做得好,能源和水的利用效率有了显著提高的地方,水电开发往往比火电和核电开发更为合适。但这意味着以后开发水电必须比以往更为有效地防止、减轻或补偿这种开发所带来的环境影响。世界银行制订新的政策正是想做到这一点。 All hydropower development projects are accompanied by some major environmental issues, especially in the tropics. However, where natural conservation is well done and the efficiency of energy and water use is significantly improved, hydropower development tends to be more appropriate than thermal power and nuclear power development. However, this means that the development of hydropower in the future must more effectively prevent, mitigate or compensate for the environmental impact of such development than ever before. The World Bank is planning a new policy precisely to achieve this.
