The US has one of the best, most reliable power grids 2 in the world, so people aren't saying 'let's knock out this entire grid 1.' You could just have one converter box in your house, and that way you're not converting AC to DC at the level of every single device.
美国拥有世界上最好、最可靠的电网,所以人们不会嚷嚷着“把整个电网砍掉。”你只要在家里装上一个转换器,这样你就不用针对每个电子产品逐一地去把电流从交流电转换成直流电。
