The first is improved energy efficiency, meaning that we should use much less energy to achieve the same level of well-being. For example, we can design our buildings to use sunlight and natural-air circulation so that they require far less commercial energy for heating, cooling, and ventilation.
这一转变有三个部分。首先是改善能源效率，这意味着我们可以使用少得多的能源实现相同水平的福利。比如，我们可以设计利用阳光和天然空气循环的建筑，这样就可以使用少得多的商业能源用于制热、制冷和通风。
