Looking ahead, the world economy will need to introduce alternative technologies that conserve energy, water, and land, or that enable us to use new forms of renewable energy (such as solar and wind power) at much lower cost than today.

展望未来，世界经济需要引进保存能源，水和土地或者可以使我们以比现在更低的成本使用新型可再生能源（如太阳能和风能）的替代技术。

For example, power plants can adopt solar energy or capture and safely dispose of the carbon dioxide they produce with fossil fuels – as can large factories.

例如，电厂可以采用太阳能或者捕获并且安全地处理其随着矿物燃料而所产生的二氧化碳，大型工厂也可以做到。
