Old refrigerators consume a lot more electricity than the highly efficient models available today. Do a quick calculation, and you would find that you would have been better off buying a second energy-saving fridge to keep than running that old energy gobbler in your garage.

通用串行总线(USB)最初只是一种将外围设备连接到PC的通信协议，现已发展成为消费电子产品和移动设备的主要功率传输标准。随着USB Type-C支持的输出功率范围的扩大，以及根据正在制定的能效法规的技术倾向性来看，这种主导地位将会持续数年。

800V系统的使用意义重大，因为它是当今400V传动系统的两倍。两倍的电压可以将充电时间减半。两倍的电压还能在给定的功率水平下将电流减半，从而减小电缆的规格和重量，从而造出更轻的电动汽车。
