新的 IPCC （国际气候变化小组）报告（ AR5 ）的第三卷（ WGIII ）中关于可再生能源的评论，看来比较 2007 年的报告（ AR4 ）乐观得多，特别重视太阳能的开发利用。 对于资源严重紧缺的实情，我们是否在今后发展中应当十分重视？ 例如有下面这样的文字。怎样理解？ The theoretical potential for RE greatly exceeds all the energy that is used by all economies on Earth . The global technical potential of RE sources will also not limit continued market growth. A wide range of estimates are provided in the literature but studies have consistently found that the total global technical potential for RE is substantially higher than both current and projected future global energy demand. 可再生能源的理论潜势大大超过了目前地球上所有经济体的能耗。全球可再生能源的技术潜势也不会限制能源市场的持续发展。现有文献提出了宽泛的估算，这些研究发现全球可再生能源的技术潜势比较当前和未来预估的全球能源需求都要高得多。 The technical potential for solar energy is the highest among the RE sources, but substantial technical potential exists for all forms of RE. The absolute size of the global technical potential for RE as a whole is unlikely to constrain RE deployment. 在各类可再生能源之中，太阳能的技术潜势最高，然而各种可再生能源都具备相当强的技术潜势。全球可再生能源的技术潜势量就整体而言不会限制可再生能源的应用。
