在全球化市场中，一国消费的部分商品/服务可能是在国外利用各种能源生产的。为了适当评估一个国家在多大程度上正在转向更可持续的能源，必须考虑到这两个方面，即沿着其境内生产的可再生能源的数量以及进口货物/服务所包含的数量。这项工作量化的太阳能贸易中使用环境扩展的投入产出模型。数值结果显示，有些国家是太阳能的净进口国（世界上任何地方为生产所需商品和服务而消耗的太阳能数量大于它们在当地产生的太阳能数量），而另一些国家则是净出口国（情况相反）。此外，人们发现，在过去二十年中，顶级经济体的太阳能生产有所增加。我们的分析旨在促进设计更有效的环境政策，以促进全球太阳能的使用。(C)2015爱思唯尔有限公司版权所有。
In a globalized market, part of the goods/services consumed in a country might be produced abroad using diverse energy sources. To properly assess the extent to which a country is moving towards more sustainable energy sources, it is imperative to consider both, the amount of renewable energy produced within its boundaries along with that embodied in the imported goods/services. This work quantifies the amount of solar energy embodied in trade using environmentally extended input output models. Numerical results reveal that some countries are net importers of solar energy (the amount of solar energy consumed anywhere in the world for producing the goods and services they require is greater than the amount of solar energy they generate locally), while others are net exporters (the opposite situation occurs). Additionally, it was found that the production of solar energy in the top economies has increased in the last two decades. Our analysis aims to facilitate the design of more effective environmental policies for promoting the use of solar energy worldwide. (C) 2015 Elsevier Ltd. All rights reserved.
