We'll need to electrify cars, switch buildings heated by natural gas furnaces to electric heat pumps, and electrify the huge amount of heat used in industrial processes.

我们需要汽车电气化，将天然气炉供热的建筑 转换为使用电热泵，并用电来满足工业过程中 使用的大量热量。

For example, electric heat pumps don't burn fossil fuels and, when you factor in savings on energy use, are cost-competitive with gas furnaces, but homeowners only change their heating and cooling systems every few decades.

例如，电热泵不燃烧化石燃料，考虑到节约能源时， 与煤气炉相比具有成本竞争力， 但房主每隔几十年才更换一次供暖和制冷系统。
