Airplane designers have done their best to minimize the pain. Since the nineteen-thirties, cabins have evolved from wicker chairs in bare metal tubes to mood-lit cocoons full of curved surfaces. The air has been pressurized so that pilots can fly up to smoother skies. The service carts have been lightened with composites and braced with built-in brakes and stay-closed drawers. Should the plane suddenly drop, the passenger seats can bear a force of sixteen g’s; the jump seats have harnesses to hold down the crew. Should a fire break out, the walls, seat backs, and tray tables are made with self-extinguishing polymers that won’t give off toxic fumes. Floor lights will guide the passengers down darkened aisles, to evacuation slides that inflate and unfurl to the land or water below.
面对这一历史性拐点，“综合能源服务”成为全行业破局的必然方向。正如中国宏观经济研究院能源研究所可再生能源发展中心副主任陶冶指出，未来的核心不再局限于单一的开发侧，而是供需匹配、技术融合等高维能力的集成，旨在为用户提供涵盖绿电供应、能效管理、需求响应等在内的“一站式”服务。
