New building designs have slashed heating and cooling costs by relying much more on insulation, natural ventilation, and solar power. Advances in nanotechnology offer the prospect of lighter construction materials that require much less energy to produce, making both buildings and vehicles far more energy efficient.
科技也在能源效率方面带来了新突破。新建筑设计通过更多依靠隔离、自然通风和太阳能降低取暖和制冷成本。纳米技术的进步为我们提供了更轻质、生产过程消耗能源更少的建筑材料，大大提高了建筑和汽车的能源效率。
