In contrast, if small-scale, diversified, community systems (such as solar power, wind power, or biogas, or water collection from ponds, lakes, and rainwater) could be used instead, this would allow greater flexibility in resource use and would reduce dependence on oil.
反之，若能以社區式、小型、分散而多元的系統取代，例如整合太陽能、風力、沼氣來供應一個社區的電力，或是併用埤塘、湖泊、雨水收集系統，分散供水，在資源使用上可以更具彈性，也降低人類對石化能源的依賴，。
