Ms. Harper believed that energy depletion will have a major impact upon the socioeconomic system that will not be resolved by turning to renewable energy alone. Through mathematical modeling, she predicted that energy consumption has grown to the point that we will never sustain our current consumption levels without plentiful and cheap fossil fuels.
She argued that we must cut our consumption, abandoning the current socioeconomic system in favor of re-localization, sustainability and decentralization. She believed it is possible for human society to achieve equitable, sustainable stability while maintaining a reasonable quality of life. To reach this goal, she recommended direct action on a grassroots level, as opposed to a reliance upon government and business.
