The world therefore needs to stimulate other kinds of spending. One powerful way to boost the world economy and to help meet future needs is to increase spending on key infrastructure projects, mainly directed at transportation (roads, ports, rail, and mass transit), sustainable energy (wind, solar, geothermal, carbon-capture and sequestration, and long-distance power transmission grids), pollution control, and water and sanitation.
因此，世界需要刺激其他类型的消费。拉升世界经济，应付未来之需的一条有力举措是增加对重点基础设施的投资，主要致力于交通（公路，港口，铁路，大运量客运），可持续性能源（风力，太阳能，地热，碳捕捉和碳封存，还有电力远距离传输系统网络），污染控制，以及用水及卫生事业。
